SUMMARY:Roger TORMO-QUERALT (Institute of Photonic Sciences (ICFO)\, Barcelona\, Spain)
DESCRIPTION:Carbon Nanotube Electromechanical Oscillators: where photons\, phonons and electrons meet\nRésumé : \nAchieving strong mechanical nonlinearities\, minimally invasive detection\, and control at the few-phonon level is a central challenge in the development of mechanical oscillators for quantum technologies\, including quantum information processing (1\,2)\, precision sensing (3)\, and tests of quantum mechanics (4\,5). In our group\, we aim to realize these capabilities using suspended carbon-nanotube mechanical oscillators coupled to electronic quantum dots. In this talk\, I will present results obtained with a device operating in the exotic dispersive ultrastrong-coupling regime (6\,7)\, where the interaction strength between a nanotube mechanical oscillator and a double-quantum-dot electronic two-level system (DQD-ETLS) exceeds the bare energy of the oscillator. In this regime\, we demonstrate a mechanical Kerr oscillator with an anharmonicity exceeding the state of the art for mechanical systems by four orders of magnitude (8). We read out the mechanical states using a superconducting cavity coupled to the square displacement (x²) of the oscillator (8)\, paving the way towards future quantum non-demolition (QND) cavity-based readout of mechanical Fock states (9). I will also show that the decay and decoherence rates of our ETLS charge qubit outperforms the current state of the art for 2DEG-based systems\, reaching the highest coherence values ever measured in a charge-based DQD-ETLS (10). \n1 A.

SUMMARY:Jonathan HOME (ETH Zürich)
DESCRIPTION:Scaling trapped-ion quantum computers\nRésumé : \nTrapped ions are among the most promising paths to realizing quantum computers\, having exhibited the highest fidelity gates and long coherence times. Scaling up will require the adoption of new technologies\, and can be facilitated by new approaches. In this talk I will describe recent work from our group in both directions. Firstly I will describe the use of integrated optics to deliver light to multiple zones of an ion trap chip in scalable manner\, and give an impression of the new types of control which might be enabled by this approach 1\,2\,3. I will then introduce a new concept for scaling trapped-ion quantum computers based on microfabricated Penning traps\, introducing flexible 2-dimensional ion transport while removing the need for high-voltage radio-frequency fields and thus improving compatibility with standardized chip fabrication 4\,5. We have used this to perform sensing of both static and oscillating magnetic and electric fields near the chip surface\, and more recently demonstrated multi-qubit gates and control of multi-dimensional arrays of ions. \n1 K.

SUMMARY:Maurizio SACCHI (CNRS - Institut des NanoSciences de Paris and Synchrotron SOLEIL)
DESCRIPTION:X-rays with Orbital Angular Momentum for spectroscopy and imaging\nRésumé : \nIn addition to the spin angular momentum (SAM) associated to the light polarization\, Laguerre-Gaussian light beams carry also an orbital angular momentum (OAM) of ℓ /photon [1]ℏ associated to an azimuthal dependence exp(iℓϕ) of the electric field phase. Over the last thirty years\, OAM beams at vis-IR wavelengths found applications in fields as different as biology\, telecommunication and imaging [2]. The azimuthal phase dependence\, with a singularity on the propagation axis\, is accompanied by a radial modulation of the intensity (ring-shaped beams)\, properties that have been used to modify local magnetic ordering\, to improve the spatial resolution in microscopy\, and to enhance the edge sharpness in phase-contrast imaging. \nOver the last decade\, several approaches to the generation of OAM beams at shorter wavelengths\, from XUV to hard x-rays\, were proposed. Potential applications are often based on the extrapolation of previous work carried out in the vis-IR range. For instance\, as for the SAM\, the handedness imposed by the OAM has been exploited to study magnetic materials [3] and chiral molecules [4]. The interest of extending the use of OAM beams from the vis-IR to the x-ray range has been growing steadily over the last few years. Nonetheless\, the offer of user accessible beamlines and endstations remains limited\, especially when one aims at independently varying both SAM and OAM in a controlled way. At the SEXTANTS beamline of the SOLEIL synchrotron\, we have implemented and commissioned a new setup for soft x-ray spectroscopy (absorption and resonant scattering experiments) with OAM beams [5]. \n1.

SUMMARY:Cyril BRESSY (Aix-Marseille Université - Institut des Sciences Moléculaires de Marseille (iSm2))
DESCRIPTION:Compartmentalized MultiCatalysis : Chirality as Probe\, Separation of Enantiomers & Catalytic Active Transport\nRésumé : \nLife solves the problem of different reaction conditions by the compartmentalization of the catalytic systems. This solution opens new opportunities for the chemists using synthetic membranes to isolate the catalytic systems. \nWe were interested to study the diffusion of molecules through a semi-permeable membrane when no gradient of concentration does exist. Chirality was found to be helpful to be used as probe to study such systems (1). A scale of diffusion energy depending on the structure of the solute was established providing fruitful lessons. \nBased on these results\, compartmentalized multicatalytic systems were set up for different goals : \n– A system where two catalysts of opposite configurations are working in each compartment leading to the physical separation of enantiomeric products starting from a racemic substrate. This is describing a case of compartmentalized parallel kinetic resolution (CPKR)(2).\n– A system to promote the active transport of a molecule able to cross a membrane. The active transport means a transfer against the gradient of concentration (3). \nReferences \n1 .  J. Hou\, S. Chevallier-Michaud\, L. Favre\, D. Hérault & C. Bressy\, J.

SUMMARY:Lucas GOEHRING (Nottingham Trent University (UK))
DESCRIPTION:Structure formation in paints and coatings\nRésumé : \nPaints and coatings are typically a mix of small particles\, like pigments\, along with a polymer glue or binder. Similar products include inks\, varnishes\, cosmetics\, ceramics and even the lithium-ion battery electrodes that power modern electric vehicles. These materials are prepared as a liquid\, spread over a surface\, and dried.  As anyone who has painted a wall will know\, however\, this process can easily go wrong. Even a well-prepared paint can develop an undesirable skin and wrinkle\, crack\, or peel\, and these coatings can also visibly degrade over time. \nIn this talk I will go through the key stages of film formation\, or how a colloidal dispersion dries.  I will show how small angle scattering experiments (SANS/SAXS) helped to elucidate how the structure of the film changes during drying\, evolving from a dilute gas of particles\, into a transient gel where capillary pressures balance electrostatic repulsion\, to a final aggregated solid. I will then turn to look at how the insight gained has led to a better understanding of mechanical instabilities like fracture\, shear banding\, birefringence\, and peeling\, as well as revealing an unexpected route to colloidal crystallisation. \nFinally\, I will summarise our recent work using neutron scattering techniques to investigate blanching\, a degradation process that can cause a visible whitening in the traditional varnishes that are used as a protective outer coating on many historically and artistically important paintings. \nSpeaker’s website: https://www.ntu.ac.uk/staff-profiles/science-technology/lucas-goehring \n— \nOrsolya Czakkel (College 9 Secretary) \nExternal visitors may ask for a site access to tellier@ill.fr \nZoom link: https://ill.zoom.us/j/95581858117?pwd=hh9paEQj6BF8u9WYzfZkvZaGspe1i3.1  – Passcode: 078610 \n

SUMMARY:Ismaele Vincent MASIELLO (TU WIEN\, Austria)
DESCRIPTION:Nonclassicality\, quasiprobabilities and weak values explored in neutron interferometry\nRésumé : \nThe violation of Bell inequalities has demonstrated that quantum mechanics exhibits features with no classical counterpart; however\, identifying the boundary between quantumness and classicality remains a nontrivial task. Quasiprobability representations and weak values are valuable tools for investigating these boundaries\, and their physical relevance has been confirmed across a range of impactful experiments. Several of these experiments have been implemented in neutron interferometry\, a platform that has historically played a central role in the study of foundational quantum mechanics and nonclassicality. Compared to typical photonic implementations\, it is less susceptible to classical reinterpretations\, as it involves a single massive particle in a superposition of two or three spatially separated paths. Moreover\, it offers several experimental advantages\, such as macroscopic beam separation\, individual control of the sub-beams\, and long interaction and coherence times at room temperature and ambient pressure. In this talk\, I will introduce weak values and quasiprobabilities as tools to investigate the quantum–classical boundary and present results obtained in neutron interferometry.\n_ \nHanno Filter (College 3 Secretary) \nExternal visitors may ask for a site access to tellier(at)ill.fr \nZoom link : https://ill.zoom.us/j/98964195699?pwd=vPhNT17CAeoDUr7QX4PjfyPnWsHuMU.1 – Password : SeminarC3 \n  \n

SUMMARY:Benjamin BACQ-LABREUIL (IPCMS\, Université Strasbourg)
DESCRIPTION:The Role of the Apical Oxygen in Cuprate High-Temperature Superconductors\nRésumé : \nScanning tunneling microscopy measurements exploiting the natural superstructure modulation of the cuprate superconductor Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$ (Bi-2212) have revealed a possible correlation between the Cu-apical-O distance and the superconducting order parameter\, as reported recently by O’Mahony et al. [1]. These observations were interpreted as evidence for a direct link between superconductivity and the charge-transfer gap\, and more broadly revived the long-standing question of the role of apical oxygens in cuprate superconductivity. In this talk\, I will discuss the impact of apical oxygen displacement on the superconducting properties of Bi$_2$Sr$_2$CuO$_{6+x}$\, Bi-2212\, and HgBa$_2$CuO$_{4+x}$ [2]\, leveraging a recently developed first-principles framework for high-temperature superconductors [3]. The quantitative agreement between our calculations and experiments allows us to unambiguously attribute the observed variations of superconducting order parameter to changes in the apical distance. We demonstrate\, however\, that the latter controls the former predominantly via the effective hole-doping of the CuO$_2$ planes\, with negligible effect on the charge-transfer gap. The modest magnitude of the order parameter modulation induced by apical-oxygen displacement alone therefore warrants caution in interpreting correlations between $T_c$ and the apical distance inferred from comparisons across different cuprate compounds. \n[1] O’Mahony\, et al.\, Proc.

DESCRIPTION:Sensing Mass at the Nanoscale : Suspended Nanochannel Resonators and NEMS-MS for Biology\nRésumé : \n\nDetermining the mass of biological nanoparticles opens new avenues for characterizing biological systems at their own scale. In this joint seminar\, researchers from LETI and IRIG will present two complementary nanoresonator platforms : Suspended Nanochannel Resonators (SNR)\, which operate in solution\, and Nanoelectromechanical Mass Spectrometry (NEMS-MS)\, which operates in the gas phase. Together\, these technologies cover a range of biological particles\, from lipid nanoparticles and extracellular vesicles to viral particles. Beyond the technical principles underlying each platform\, selected applications will illustrate the potential of these approaches for the characterization of biological samples.​​​​​\n​\n\n\n\nLes séminaires et soutenances sont ouverts à tous\, notez toutefois que l’accès au campus EPN nécessite un avis de rendez-vous.

SUMMARY:Dario DAGHERO (Department of Applied Science and Technology\, Politecnico di Torino)
DESCRIPTION:Point Contact Andreev-Reflection Spectroscopy : mechanisms\, models and examples\nRésumé : \nPoint-contact spectroscopy [1] in superconductors\, also known as point-contact Andreev-Reflection spectroscopy (PCARS) is a simple but powerful and versatile technique that allows a direct determination of the number\, the amplitude and the symmetry of the energy gap(s) in superconducting materials [2\,3]. The technique is rather simple in principle\, i.e. it just consists in creating a small (point-like) contact between a normal metal and a superconductor\, and to measure its differential conductance as a function of the bias voltage across the junction. However\, there are several complications that make this simple recipe fairly difficult to realize in practice. First of all\, the contact must be in the spectroscopic regime [1\,2\,3]\, i.e. electrons from the normal metal must be injected in the superconductor with an excess energy that coincides with eV\, V being the bias voltage. Hence\, they must not lose energy in the banks and in the contact itself. The ideal condition is that of ballistic conduction through the N/S interface\, which ensures no Joule effect and requires in turns that the contact size is smaller than both the coherence length and the electronic mean free path in the superconductor.\nWhen these conditions are met\, the conduction through the contact is dominated by Andreev reflection\, a quantum phenomenon that is responsible for the conversion of the normal current into supercurrent\, and occurs in a specific range of voltages (electron energies) set by the amplitude of the superconducting gap. Several models have been proposed to describe the phenomenon and are currently used to extract information on the amplitude and symmetry of the order parameter from the spectra. The simplest one [4] was only suited for superconductors with an isotropic (s-wave) gap\, but has been successfully generalized to the case of layered materials with anisotropic gaps\, like cuprates [5\,6] or strontium ruthenate [7]) and finally to the 3D case\, while taking into account the shape of the actual Fermi surface [3]. The latter generalization allows calculating the point-contact spectrum for any symmetry of the order parameter\, including exotic ones with horizontal node lines.\nAfter discussing these general aspects\, I will briefly describe the application of the technique to some example materials\, from the conventional multiband superconductors MgB2 [8] to unconventional ones like Pu-based heavy fermion compounds [9] or Fe-based compounds [3]\, to transition-metal dichalcogenides [10]. \nReferences\n1.

SUMMARY:Carlotta PORZIO (CERN\, Switzerland)
DESCRIPTION:Experimental activities at the ISOLDE-CERN facility\nRésumé : \nThe ISOLDE factily at CERN is one of the world-leading laboratories for the production of radioactive ion beams (RIBs) with the ISOL (Isotope Separation On-Line) method. More than 1000 isotopes of over 70 chemical elements have been produced via the interaction of a 1.4 GeV proton beam with a variety of target materials. After ionization and mass separation\, the beams can be delivered at low energy or post-accelerated up to about 10 MeV/u using the HIE-ISOLDE linear accelerator. The facility supports a broad scientific program\, spanning nuclear structure studies\, nuclear astrophysics\, materials science\, life sciences\, and investigations of fundamental interactions. \nAmong the experimental setups available at HIE-ISOLDE\, the Miniball gamma-ray spectrometer is employed to investigate both collective and single-particle properties of exotic nuclei. Combined with the post-accelerated radioactive ion beams\, Miniball enables nuclear structure studies via Coulomb excitation and nucleon-transfer reactions. \nThis seminar will provide an introduction to the ISOLDE facility and the ISOL RIB production method\, and an overview of experimental setups and techniques\, with a focus on the Miniball spectrometer. \n— \nHanno Filter (College 3 Secretary \nExternal visitors may ask for a site access to tellier@ill.fr \n
