Quantized heat flow in the Hofstadter butterfly
Résumé :
When subjected to a strong magnetic field, electrons on a two-dimensional lattice acquire a fractal energy spectrum called Hofstadter’s butterfly. In addition to its unique recursive structure, the Hofstadter butterfly is intimately linked to non-trivial topological orders, hosting a cascade of ground states characterized by non-zero topological invariants. These states, called Chern insulators, are usually understood as replicas of the ground states of the quantum Hall effect, with electrical and thermal conductances that should be quantized, reflecting their topological order. The Hofstadter butterfly is now commonly observed in van-der-Waals heterostructures-based moiré superlattices. However, its thermal properties, particularly the quantized heat flow expected in the Chern insulators, have not been investigated, potentially questioning their similarity with standard quantum Hall states. Here we probe the heat transport properties of the Hofstadter butterfly, obtained in a graphene / hexagonal boron nitride moiré superlattice. We observe a quantized heat flow, uniquely set by the topological invariant, for all investigated states of the Hofstadter butterfly: quantum Hall states, Chern insulators, and even symmetry-broken Chern insulators emerging from strong electronic interactions. Our work firmly establishes the universality of the quantization of heat transport and its intimate link with topology. A. Zhang, et al., arXiv:2601.05694 (2026)

One-to-one correspondence between two-point correlators and entanglement in magnetic systems
Résumé :
There are multiple measures of multipartite entanglement — including entanglement in thermal mixtures — currently used to study many-body interacting systems. Recently, Quantum Fisher Information has been proposed as a multipartite entanglement measure that can be connected to experimentally accessible observables. In this talk, I will present our recent findings about a one-to-one correspondence between two-point correlators and a certain general class of Heisenberg-like Hamiltonians and wavefunctions. This is a foundation of our claim that a mapping from finite-temperature observables to any entanglement measure exists for such systems. Furthermore, I will present our results of training a convolutional neural network (CNN) to recognize and predict the entanglement for one-dimensional anisotropic XY and XYZ models, which exhibit an entanglement transition. From our preliminary results we found that entanglement can be accurately predicted by a CNN using both static and dynamical correlators, even when the network is trained on only a fraction of the full dataset or on data from a different system than the one used for prediction. Specifically, when trained on observables from an anisotropic XY model, accurate predictions can be achieved using only about 3% (6%) of the data when employing dynamical two-point correlators (structure factors) for learning.

Spin-orbit torque based magnetic memories evaluation for cryogenic applications
Résumé :
The rapid development of cryogenic computing platforms, including superconducting electronics, quantum information processors, high-performance computing systems, and space applications, has created a demand for memory technologies that operate efficiently, reliably, and scalable at low temperatures. While magnetic random-access memory (MRAM) is a mature and commercially deployed non-volatile memory at room temperature, its behaviour and limitations at cryogenic temperatures remain insufficiently explored, particularly for three-terminal spin-orbit torque magnetic tunnel junctions (SOT-MTJs). This thesis presents a comprehensive experimental and modelling study of SOT-based magnetic memories operated from room temperature (300 K) down to liquid-helium (4 K) temperatures. A dedicated cryogenic characterisation framework is developed to extract magnetic parameters, quantify switching statistics, and evaluate write performance under both quasi-static and sub-nanosecond pulsed conditions. Temperature-dependent measurements reveal enhanced magnetic anisotropy and thermal stability at low temperatures, accompanied by non-trivial trends in critical switching current. By combining experiments with micromagnetic simulations incorporating temperature-dependent material properties and transient Joule heating, this work demonstrates that self-heating remains a dominant factor during write operations, especially at cryogenic bath temperatures. Beyond conventional SOT-MRAM, complementary approaches including optimised spin-transfer torque devices and voltage-gate-assisted SOT switching are investigated. They show that controlling retention via storage layer thickness is a relevant strategy to decrease write current while electric-field control of anisotropy enables efficient modulation of switching across a large temperature range. Overall, this thesis establishes both the physical limitations and technological potential of SOT- and voltage-gated SOT-based MRAM as viable candidates for future cryogenic memory systems.

Quantum optics with radiation on the move
Résumé :
With the scaling of quantum technologies to many separate material quantum components, we may have to couple these systems by propagating quantum radiation, in the form of light, microwaves or phonons. There are, however, rather fundamental obstacles to the treatment of propagation of quantum radiation and its interaction with matter. These obstacles include the general multimode character of propagating fields and the duration and spatial extent of useful light and microwave pulses. The talk will review a recent theoretical approach to deal theoretically with these obstacles, and it will present examples of new, unforeseen, possibilities for easy preparation and manipulation “on the fly” of quantum states of light and matter.

Twist-Angle-Controlled Anomalous Gating in Bilayer Graphene/BN Heterostructures
Résumé :
Anomalous gating effects—such as gate ineffectiveness and pronounced hysteresis—have been observed in graphene-based systems encapsulated in boron nitride (BN) and linked to a possible ferroelectric state. However, their origin, stability, and reproducibility remain under debate. During this talk, I will present charge transport experiments in dual-gated, dynamically rotatable van der Waals heterostructures based on bilayer graphene encapsulated in BN. Remarkably, the angular degree of freedom acts as an ON/OFF switch for the anomalous gating response. We show that the angular alignment between the two BN layers is the key parameter governing these effects. Both gate ineffectiveness and hysteresis are highly sensitive to small angular changes, and they clearly change in behavior, which we classify into three distinct regimes.

Neutron and x-rays scattering on quantum magnets at high pressures and low temperatures
Résumé :
Application of external pressure acts as clean tuning parameter of inter-atomic distances and bond angles and therefor allows for precise control of magnetic interactions in condensed matter. Extreme conditions can thus be used to stabilize novel quantum phases and drive systems close to quantum criticality where new and exciting phenomena are expected. Within this seminar I will show how recent advances in neutron and x-ray scattering allows to access fingerprints of quantum correlations and present novel results on quantum magnets at the extreme.

The search for neutron electric dipole moment at PSI
Résumé :
The Universe and its history are simultaneously very well understood and still a big mystery. We have amazing tools from satellites to
observatories to weight the universe over its history. But the components of the Universe can simply not yet be explained by physicists. To get the full picture, we need to identify and understand the interactions at play throughout the life of the Universe. This is the meeting point between particle physics and cosmology. At this meeting point stands the neutron, a common particle that we can uniquely use in high precision experiments.
I will present how experiments searching for a permanent electric dipole moment of the neutron (nEDM) aim at discovering new sources of CP violation beyond the Standard Model of particle physics and understanding the origin of the matter-antimatter asymmetry of the Universe. The quest for the neutron electric dipole moment started more than sixty years ago. In recent experiments, polarized ultra-cold neutrons are stored in material bottles.
I will present the ongoing efforts at the Paul Scherrer Institute in Switzerland where the n2EDM spectrometer has taken the first “physics data” in 2025. A large fraction of this dataset is dedicated to measurements of the UCN spectrum. I will present the newest UCN spectroscopy techniques that were recently published and the reasons for the importance of a deep understanding of the UCN spectrum.

Chiral charge density waves in EuAl4 and related compounds
Résumé :
The BaAl 4 structure type has centrosymmetric, tetragonal symmetry, I4/mmm, with three crystallographically independent atom sites: Ba, Al1 and Al2. Solid solution series RAl 4-x Gax (R= Eu, Sr, Ca, Ba; 0 < x < 4) crystallize in this structure type [1], where Ga preferably occupies the Al2 site. Accordingly, complete chemical order is found for x = 0, 2, 4. Incommensurate charge-density waves (CDWs) have been observed in several of these ordered compounds. For the other values of x, lack of chemical order leads to suppression of the CDW transition. At much lower temperatures (T = 10–30 K) magnetic order appears for the compounds with magnetic Eu atoms. Here, we present the crystal structures of the incommensurate CDWs of EuAl 4 , EuAl 2 Ga2 and SrAl 4 . In particular, the symmetry of the CDWs is analyzed in view of x-ray diffraction data (present data [2–5]), and results of transmission electron microscopy (TEM), density functional theory (DFT) calculations and inelastic x ray scattering (IXS) from the literature [6–8].

Development of the combinatorial approach for the CVD thin film deposition process : Multiphysics coupling and machine learning
Résumé :
The combinatorial approach applied to chemical vapor deposition processes integrating high-throughput experiments, computational simulations, and machine learning seems to emerge as a transformative paradigm to accelerate the discovery of novel materials. Through systematic gradient explorations, large-scale datasets can be generated to deepen our understanding of process-structure-property relationships. Machine learning models, trained on experimental and simulated data enable rapid prediction and identification of high-potential solutions, thereby guiding future experiments and simulations. The synergy not only reduces the time or cost associated with material discovery but also unlocks access to previously unexplored regions of the materials space.
Short Bio/CVMy academic journey began in Grenoble, where I studied chemistry before developing a keen interest in materials sciences, particularly nanostructures and their processing. Driven by a desire to unravel the underlying mechanisms, I started my PhD in Toulouse, between the CIRIMAT and LGC. There, I expanded my expertise in chemical engineering and Multiphysics simulation. After nearly two years of postdoctoral research, I sought to broaden my research perspective and joined Polytechnique Montréal in the chemical engineering section for two postdoctoral positions that led to an associate professor role. However, my longing for French cheese proved irresistible, I successfully secured a position at CNRS and joined SIMaP in February 2026.

Optimisation et caractérisation avancée de couches minces de zircone stabilisée à l’yttrine par dépôt chimique d’organométalliques en phase vapeur pour des cellules électrochimiques à oxydes solides
Résumé :
Notre consommation énergétique et l’électrification de notre production afin de la décarboner. Le développement des énergies solaire et éolienne est cependant freiné par leur défaut principal : leur intermittence. Le stockage saisonnier de l’énergie sous forme d’hydrogène est une solution prometteuse pour pallier à ce défaut. EPISTORE est un projet de recherche européen visant au développement d’une cellule électrochimique à oxydes solides (SOC), réversible, en couche mince, basse température (< 500°C). Ces dispositifs sont en effet particulièrement pertinents pour la conversion électricité-gaz.
Cette thèse, dans le cadre d’EPISTORE, projet du programme de recherche et d’innovation Horizon 2020, vise au développement de couches minces de zircone stabilisée à l’yttrine (YSZ) pour servir d’électrolyte pour ces SOCs. Le YSZ, contenant 8 mol% d’yttrine (8YSZ) est un matériau déjà largement utilisé comme électrolyte dans les dispositifs électrochimiques en céramique. Ses propriétés lui permettent de conduire efficacement les ions oxygènes tout en formant une barrière électronique. L’étude des couches minces de YSZ fabriquées au cours de cette thèse doit permettre d’évaluer la pertinence de réduire la quantité d’yttrine dans le matériau. En effet, les travaux publiés sur le sujet suggèrent qu’une concentration de 3 mol% ou 4 mol% d’yttrine pourraient améliorer les propriétés mécaniques, vitales pour des dispositifs en couches minces.
Ce travail détaille l’optimisation de la synthèse de ces films par dépôt chimique en phase vapeurs d’organométalliques (MOCVD) puis la caractérisation avancée de ces échantillons, non seulement structurellement et morphologiquement (XRD, TEM, SEM, Raman…) mais aussi de leurs propriétés électriques via de la spectroscopie d’impédance électrochimique (EIS) ou mécaniques via nanoindentation et tests de déformation. Une nouvelle technique d’observation directe de la diffusion ionique impliquant des traceurs isotopiques et de la spectroscopie Raman a aussi été adaptée à ce matériau pour la première fois.
Les résultats obtenus suggèrent que l’emploi de 3YSZ et 4YSZ à basse température (< 500 °C) permettent d’obtenir des performances électrochimiques équivalentes ou supérieures au 8YSZ. Un effet positif de ce changement de concentration sur les propriétés mécaniques des films n’a cependant pas été démontré.

Magnetism and spin dynamics of a weakly interacting rare-earth stretched diamond lattice
Résumé :
In condensed matter physics, a quantum-disordered ground state is characterized by the absence of long-range order down to absolute zero temperature, where the disorder is driven by quantum fluctuations that persist even at T=0. On the other hand, the magnetism of rare-earth materials is particularly intriguing as it originates from their localized 4f electrons, which exhibit strong spin–orbit coupling, pronounced magnetic anisotropy, and relatively weak exchange interactions between magnetic ions. These unique characteristics, when combined with suitable lattice geometry, can give rise to a wide variety of unconventional magnetic ground states.
A diamond magnetic lattice is a bipartite network and in its ideal form, does not exhibit geometric frustration. However, “stretched” diamond lattices have recently gained attention where frustration can emerge due to competition between nearest-neighbor (J1) and next-nearest-neighbor (J2) exchange interactions, despite preserving the bipartite nature. In this context, we investigate the magnetic ground state of the rare-earth molybdate compound Na5Yb(MoO4)4, which crystallizes in a stretched diamond magnetic lattice. This compound can be viewed as a complex derivative of the conventional scheelite- type ABO4 structure, crystallizing in the tetragonal space group I41/a. The magnetic lattice in Na5Yb(MoO4)4 is highly unusual, featuring a remarkably large nearest-neighbor Yb–Yb separation of approximately 6.3 Å, in contrast to previously studied stretched-diamond systems where the J1 distance typically lies in the range of 3–5 Å and is predominantly governed by superexchange interactions. Furthermore, the next-nearest-neighbor (J2) Yb–Yb distance exceeds 9 Å, significantly weakening the J2 exchange interactions. As a result, magnetic frustration arising from competing J1–J2 exchange is significantly suppressed in Na5Yb(MoO4)4, distinguishing it from other frustrated diamond-lattice systems.
We employ neutron and synchrotron X-ray diffraction to elucidate the structural details of Na5Yb(MoO4)4. The magnetic properties and ground state are investigated using bulk magnetic susceptibility measurements, specific heat studies, and muon spin relaxation (μSR) experiments. In addition, density functional theory calculations within the DFT+U framework are used to provide theoretical support for the experimental findings. Our results establish Na5Yb(MoO4)4 as a rare example of a dipolar quantum paramagnet in which single-ion physics and long-range dipolar interactions dominate, while exchange interactions are suppressed to the millikelvin energy scale.

A new magnetic state, “B-Phase”, found in MnSi at Low Temperatures
Résumé :
In cubic chiral magnets, Dzyaloshinskii-Moriya (DM) interactions within the chiral crystal structure result in diverse magnetic textures, including skyrmion lattices (SkL) and chiral soliton lattices, which hold promise for spintronic and magnonic devices. Among these, MnSi has been extensively studied due to the SkL formation in the so-called “A-phase” just below Tc [1]. Recently, it was suggested theoretically that at low temperatures (T), the conical helimagnetic (CH) and forced-ferromagnetic (FFM) phases in MnSi might not be directly connected but separated by another SkL phase, possibly metastable, or a new phase of unknown nature near the critical magnetic field (Bc) [2]. The theoretical prediction of the new SkL phase at low T is in good agreement with the experiments reported in MnSi and Cu2OSeO3 [3,4]. On the other hand, by using careful ac susceptibility measurements at low temperature, we determined the magnetic phase diagrams of oriented crystals of MnSi [5]. A new unexpected region, termed “B-phase”, was observed when the magnetic field was applied along the main diagonal <111>.
To clarify the nature of the “B-phase”, we performed small-angle neutron scattering (SANS) measurements at TAIKAN in J-PARC and transverse field (TF)-μSR experiments at TRIUMF. At low temperatures and fields near Bc, SANS patterns revealed two peaks along the horizontal axis, corresponding to the magnetic Bragg peaks of the CH state. Notably, no diffraction peaks indicative of a six-fold-symmetric SkL were observed. Meanwhile, μSR results showed a distinct internal magnetic field distribution in the “B-phase”, different from those in the CH or FFM phases, suggesting that the “B-phase” could involve a reorientation of Mn helices within the unit cell.
In the presentation, we will discuss these SANS and μSR findings in detail and their implications for understanding the spin texture in the “B-phase”.

Empirical machine learning for 3He spin-filter polarisation decay
Résumé :
A lightweight, empirical machine-learning framework is presented for predicting the time evolution of the nuclear polarisation of 3He spin-filter cells under realistic neutron beam line conditions. The method bridges the gap between detailed microscopic modelling of polarisation relaxation and purely heuristic correction schemes by combining supervised learning with basic physics-informed constraints on spin relaxation. This strategy ensures physically consistent polarisation forecasts while maintaining computational efficiency and ease of implementation.
The framework is tailored to the limited number of heterogeneous experimental datasets typically encountered during routine instrument operation. Rather than explicitly modelling all relaxation mechanisms, it learns an effective representation of polarisation decay directly from experimental data. Within the domain spanned by the training dataset, the model demonstrates stable predictive performance while preserving the expected exponential relaxation behaviour and accommodating non-linear, history-dependent effects.
The resulting predictions enable reliable, time-dependent corrections of neutron scattering data affected by polarisation efficiency drift. Compared with traditional single-parameter relaxation models, the approach accounts for the combined influence of multiple experimental parameters and their temporal evolution. Although extrapolation beyond the training domain requires careful validation, the method provides an operationally efficient and reproducible tool for polarisation monitoring and correction in realistic experimental environments.
