  • Nanofluidics meets condensed-matter physics : challenges and perspectives at the Quantum Plumbing Lab

    LiPhy, Salle de Conférence 140 rue de la Physique, St Martin d'Hères

    Nikita Kavokine (EPFL, Switzerland) The hydrodynamic wall has traditionally been considered a featureless object, whose only role is to provide a boundary for the fluid flow. Yet, there is now ample evidence that at nanometer scales, fluid flows are sensitive to the wall’s internal degrees of freedom. Recently, we have developed a field theory formalism […]

  • Isotropic amorphous topological phases – Daniel VARJAS

    LPMMC CNRS – Bat G, salle Roger Maynard G-421, Grenoble

    Résumé : Topological phases of matter are distinguished by robust properties that are insensitive to perturbations. These include quantized responses, perfectly conducting interfaces, and exactly zero energy modes, with wide-ranging technological applications. Recent years saw the complete classification of topological band structures, revealing an abundance of topological crystalline insulators. Many questions about the robustness of these […]

  • Structure and transport in 2D-nanoconfined electrolytes – Damien TOQUER (ENS Paris)

    LiPhy, Salle de Conférence 140 rue de la Physique, St Martin d'Hères

    Résumé : Recent experimental advances in nanofluidics have enabled the exploration of ion transport across molecular-scale pores. Conductance and flow measurements show that electrostatic coupling between the ions and the confining walls plays a major role. Despite these advances, direct measurements of ionic behaviour in such small systems remain challenging. Numerical simulations and theoretical modelling […]
