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 […]

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 […]

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 […]
