Nicolas Tancogne-Dejean (MPSD, Hambourg) All-optical spectroscopy of matter is a well-established technique to access properties of electrons and quasi-particles in matter. The description of these optical properties is usually done employing ab initio methods based on linear response theory. The recent advances in experimental techniques have opened up the possibility to develop novel types of… Read More »Advances in optical spectroscopies of solids : Insight from ab initio simulations (Nicolas Tancogne-Dejean / LPT / Seminar) – 16/11 – 14H.

Darka Labavic (Laboratoire Jean Perrin) - en visio In humans, the digestive tract contains the majority if the microbiota which is essential for the health of an individual. The digestive tract itself, is a complex system from a point of view of geometry, fluid mechanics, population dynamics, and biodiversity. In this work, we propose a… Read More »Hydrodynamic flow and concentration gradients in the gut enhance neutral bacterial diversity (Darka Labavic / LPT / seminar). – 23/11, 14 H.

Aurélien Manchon (CINaM, Université d’Aix-Marseille) Magnetic materials lacking inversion symmetry constitute a unique platform for the exploration and control of magnetism. In these systems, typically multilayers of transition metal ferromagnets and heavy metals (W, Pt, Bi2Se3 etc.), interfacial spin-orbit coupling promotes a wealth of physical phenomena, among which the emergence of magnetic skyrmions, spin-to-charge conversion,… Read More »Spin-Orbit Physics at Magnetic Interfaces (Aurélien Manchon / LPT / Seminar). – 7/12, 14 H.
