SUMMARY:Vadim PLASTOVETS (University of Augsburg)
DESCRIPTION:Cavity-controlled superconductivity : interplay of matter and photonic fluctuations\nRésumé : \nConfining electromagnetic fields in a cavity reshapes the photonic environment of a superconductor\, providing a tunable control of its superfluid stiffness. We show that the sign of this effect depends qualitatively on the underlying superconducting regime. In conventional low-temperature BCS superconductors\, cavity-photon-mediated electron-electron interactions renormalize the kinetic mass of Cooper pairs\, leading to a reduction of effective superfluid density near critical temperature. In contrast\, in phase-fluctuating two-dimensional superconductors (such as underdoped cuprates)\, the cavity reshapes the collective plasma mode and can thereby suppress thermally excited phase fluctuations\, effectively enhancing the superfluid stiffness. These theoretical findings provide a possible explanation for recent experimental observations in niobium- and cuprate-based systems. \n_ \nContact : pierre.nataf@lpmmc.cnrs.fr

SUMMARY:Soutenance de Thèse par Lucie RIVET (CEA-Irig/SyMMES)
DESCRIPTION:Synthèse et caractérisation de polymères d’accepteurs non fullerène stables pour des cellules solaires « tout polymère »\nRésumé : \nAu cours des cinq dernières années\, les cellules solaires organiques (CSO) ont montré une forte progression de leurs performances dépassant 20% de rendement photovoltaïque en 2022. La formulation de ces deux matériaux sous forme d’encre imprimable rend possible l’industrialisation de ce procédé sur des substrats flexibles et par des techniques d’impression à haute vitesse. La bascule vers l’industrialisation à grande échelle est proche mais il reste à s’affranchir de plusieurs verrous technologiques importants. Parmi les approches permettant d’augmenter la stabilité des couches actives\, le remplacement des petites molécules acceptrices appelée accepteurs non fullerène par leurs dérivés polymères a récemment attiré notre attention. Ils présentent plusieurs avantages : une grande facilité de formulation sous forme d’encres solubles dans des solvants non halogénés\, une nano-morphologie robuste permettant une stabilité à long terme et l’accession a des couches plus épaisses grâce au mélange de deux polymères.​​​​​

SUMMARY:Soutenance de thèse par Tanisha BADHAURIA
DESCRIPTION:Étude des effets électromécaniques dans des nanofils semi-conducteurs piézoélectriques\nRésumé : \nZinc oxide (ZnO) nanowire (NWs) are promising materials for nanoelectromechanical systems (NEMS) and piezoelectric energy harvesting due to their coupled piezoelectric\, semiconducting nature and compatibility with low temperature synthesis methods. Theoretically\, ultra-thin ZnO NWs are expected to show a substantial increase in the piezoelectric response\, but their experimental fabrication and integration into functional devices still present difficulties. This thesis explores the effects of NW geometry\, d efect chemistry and device architecture on the electromechanical response of hydrothermally grown ZnO NWs. Two device architectures are developed for advanced nanoscale characterization\, including individual laterally contacted NW devices and vertically integrated Piezoelectric energy generators (PEGs). We report the first successful integration of electrically functional devices \nand (PEGs) with vertically aligned ultra-thin ZnO NWs of diameter about 20 nm for the experimental study of their piezoelectric behaviour. The systematic post-growth treatments like oxygen annealing\, vacuum annealing and oxygen plasma exposure are investigated by XRD\, FESEM\, PL\, XPS\, KPFM\, s-MIM and PFM. An oxygen annealing at 500° C showed that the free-carrier screening is reduced and increases the effective piezoelectric coefficient from 5.3 pm/V to 6.2 pm/V\, a 17% enhancement\, while \, preserving the NW morphology. Combining the size reduction of ZnO NWs to ultra-thin with oxygen annealing result in a synergistic enhancement of the piezoelectric performance. The oxygen annealed PEGs fabricated from 20-nm-diameter and 1-μm-long ZnO NWs showed a maximum output voltage of 134 mV under the applied force of at 1N\, which is an enhancement of about 306% compared to the devices based on the thicker (~80 nm) NWs which was 33mV. The results directly link the dimensions\, defect chemistry\, and electromechanical response\, showing that combining diameter engineering and defect engineering is an effective strategy for optimizing ZnO-basedpiezoelectric devices for future self-powered sensors and energy harvesting applications. \n_ \nContact : deborah.verger@grenoble-inp.fr

SUMMARY:Arthur GOETSCHY (Institut Langevin\, ESPCI Paris)
DESCRIPTION:Light\, a random walker ?\nRésumé : \nHow do waves such as light or sound propagate through fog\, paint\, or biological tissue? For decades\, this process has been described in terms of the diffusion of wave intensity. However\, this picture misses an essential ingredient: interference between distinct scattering paths. In this talk\, we will explore two situations in which interference profoundly alters wave transport. In the first part\, we will introduce a new propagation equation that describes how specially shaped waves\, such as open transmission channels created using wavefront-shaping techniques\, evolve inside scattering media. This provides access to the spatial structure of transport beyond the conventional diffusion picture. In the second part\, rather than shaping the wave\, we will shape the medium itself. We will show how strong spatial correlations can create pseudogaps and dramatically suppress wave transport\, leading to an Anderson-type transition with intriguing connection to percolation. This effect will be illustrated for vector light propagating through three-dimensional disordered media. \n_ \nContact : dorian.bouchet@univ-grenoble-alpes.fr

SUMMARY:Giovanna MORIGI (Saarland University)
DESCRIPTION:Searching a quantum database using noise\nRésumé : \nEfficient retrieval of information is a core operation in the world wide web\, is essential for the sustainance of living organism\, and is a paradigm for optimization. Quantum physics holds the promise for a quadratic speedup with respect to existing classical search algorithms. Achieving such speedup\, however\, requires an outstanding degree of control of the quantum dynamics of systems of large size. This implies the suppression and corrections of the errors induced by the unavoidable action of the external environment. In this talk\, we will take inspiration from foraging in nature\, which results from the interplay of deterministic dynamics and stochasticity\, and discuss examples of quantum search dynamics emerging from the interplay between quantum coherent processes and the action of an external reservoir. We will discuss how these insights can contribute to our understanding of out-of-equilibrium dynamics in the quantum world and of the mechanisms of their stabilization\, and how they could pave the way for a novel class of robust quantum algorithms. \n_ \nContact : sergey.skipetrov@lpmmc.cnrs.fr

SUMMARY:Buyun ZHENG (doctorant)
DESCRIPTION:Physical properties and structure–property relationships in silver nanowire networks for low-emissivity applications\nRésumé : \nThe increasing demand for energy-efficient windows has stimulated the development of transparent low-emissivity (low-E) coatings capable of reducing radiative heat transfer while maintaining high visible transparency. Conventional low-E technologies\, such as metal-based multilayer structures and transparent conductive oxides\, provide high optical and infrared performance but may involve limitations related to flexibility\, processing\, or manufacturing complexity. Silver nanowire (AgNW) networks have emerged as a promising alternative owing to their low infrared emissivity\, high optical transparency\, mechanical flexibility\, and compatibility with scalable deposition processes. \nThis thesis investigates the physical properties of AgNW networks and their potential integration into low-E coatings\, with particular emphasis on structure–property relationships. The influence of key structural parameters\, including nanowire diameter\, length\, density\, and alignment\, is investigated through experimental characterization and physical analysis. In particular\, an optical percolation transition is identified at a network density well above the electrical percolation threshold\, accompanied by a transition in infrared angular emissivity from dielectric-like to metallic-like behavior. Furthermore\, dense AgNW networks are further shown to follow a generalized Hagen–Rubens relationship\, enabling infrared emissivity to be directly related to the electrical properties of the network. The impact of nanowire dimensions and network topology on low-E performance is further investigated to identify the structural parameters governing the trade-off between visible transparency and infrared emissivity. The stability of AgNW networks is also addressed through the deposition of oxide layers by spatial atomic layer deposition (SALD)\, with the aim of improving environmental and thermal stability while assessing their influence on the optical and emissive properties of the resulting coatings. Overall\, this work contributes to a more comprehensive understanding of the structure–property relationships in AgNW networks and provides physical insights into their use as transparent low-E coatings for energy-efficient applications. \nShort Bio/CV \nBuyun Zheng is a PhD student at the Laboratoire des Matériaux et du Génie Physique (LMGP).  His research focuses on the physical properties of silver nanowire (AgNW) networks and their integration into low-emissivity (low-E) coatings for energy-efficient windows. His work investigates how network structure influences the electrical\, optical\, and infrared properties of AgNW networks\, with particular interest in percolation phenomena and network topology. \n_ \nContact : deborah.verger@grenoble-inp.fr

SUMMARY:Michael SONNER (UC Berkeley)
DESCRIPTION:Multibath Influence Matrices : Universal Scaling from Real-Time Dynamics\nRésumé : \nWe introduce a framework for describing the real-time dynamics of quantum impurity models out of equilibrium which is based on the influence matrix approach. By replacing the dynamical map of a large fermionic quantum environment with an effective semi-group influence matrix (SGIM) which acts on a reduced auxiliary space\, we overcome the limitations of previous proposals\, achieving high accuracy at long evolution times\, which we demonstrate by computing the spectral function of the single impurity Anderson model. Once the effective compressed baths are obtained\, they can then be used as building blocks\, allowing the study of more complex models such as the two impurity Anderson model. At a coupling strength between the two dots comparable to the Kondo scale this model is known to host a two channel Kondo like non-fermi liquid point. We study this critical point by considering dynamical observables such as the relaxation time after a quench and the work exerted on a ramp through the critical point exhibiting Kibble Zurek like physics. Finally I’ll discuss applications of this method to non-equilibrium dynamical mean field theory. \nContact : loic.herviou@lpmmc.cnrs.fr

SUMMARY:Diego GARCIA OVALLE (Université de Sherbrooke)
DESCRIPTION:Spin and orbital angular momentum in periodic solids : From nonmagnetic to magnetic materials\nLe séminaire théorie est financé par la fédération de recherche Quantalps. \nRésumé : \nOver the past few years\, the study of the electron’s degrees of freedom have received a major interest in condensed matter\, both theoretically and experimentally. In particular\, investigating the spin and the orbital angular momentum is a source of a fascinating landscape of new physics in periodic systems\, where materials that are effectively nonmagnetic and even composed with light elements can be used for the new generation of more efficient electronic devices. \nIn this talk\, I will explain from the theory point of view how these two fundamental properties of the electron have a dramatic impact on the nonequilibrium responses of quantum materials. Firstly\, in the nonmagnetic case\, I will describe how the angular momentum of the electron can be connected to the nonlinear Hall effect in noncentrosymmetric materials. When moving forward to analyze spin and orbital transport exclusively\, I will focus on distinguishing the role of spin-orbit coupling and the Rashba effect on the spin and orbital-to-charge conversion in materials without inversion symmetry\, which are key figures of merit for the optimization of the basic structures in data storage. Secondly\, we will switch the gear to ferromagnetic materials to discuss two distinct effects in low symmetry crystals that emerge from the trigonal warping of the Fermi surface: A special class of spin-orbit torque and the so-called crystalline in-plane Hall effect. Last but not least\, I will present an important prospect of my work that aims to exploit the spin and the orbital angular momentum in antiferromagnets and altermagnets from surface engineering. Here\, I will illustrate the instance of the nonequilibrium spin polarization reported very recently\, and its potential extension to superconductivity. Exploring nonequilibrium responses arising on the spin or the angular momentum serve not only as a probe of the electronic structure of quantum materials\, but also as tools that might shed light on how to control them externally for novel applications in spin-orbitronics. \n_ \nContact : serge.florens@neel.cnrs.fr

SUMMARY:Bin LAI (UFZ\, Germany)
DESCRIPTION:Synthetic electro-biotechnology : Bridging electrochemistry with microbiology to push the biotechnology boundaries\nRésumé : \nMathematics defines the boundaries of biology. In developing a biotechnological process\, one of the most fundamental design principles is the conservation of mass and energy. These balances define the stoichiometric limits of carbon and electron partitioning across the product spectrum\, thereby constraining achievable product yields and\, ultimately\, process rates and titers. In this seminar\, I will introduce our approach to tackling these intrinsic constraints through a hybrid bioelectrochemical strategy. Specifically\, we develop a mediator-based extracellular electron transfer pathway that enables selective targeting and modulation of microbial electron flow. The integration of electrochemistry and microbiology offers a promising solution to partially decouple microbial carbon and electron balances\, thereby overcoming the natural upper limits of conventional biotechnology. \n_ \nContact : natale.scaramozzino@univ-grenoble-alpes.fr

DESCRIPTION:Quantum simulation with Fluxonium Qutrit Arrays\nRésumé : \nFluxonium superconducting circuits were originally proposed to realize highly coherent qubits. In this talk\, we explain how these circuits can be used to implement and harness qutrits\, by tuning their energy levels and matrix elements via an external flux bias. In particular\, we investigate arrays of fluxonium qutrits\, and their potential for the quantum simulation of exotic quantum matter. We identify different operational regimes\, classified according to the plasmon-like versus fluxon-like nature of the qutrit excitations. Highly tunable on-site interactions are complemented by correlated single-particle hopping\, pair hopping and non-local interactions\, which naturally emerge and have different weights in the different regimes. We investigate the rich ground-state phase diagram of qutrit arrays and propose practical dynamical experiments to probe the different regimes. Future directions towards analogue simulation of exotic quantum matter are presented. \n_ \nContact : equipe-seminaires-nano@listes.grenoble.cnrs.fr
