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.

Jerôme Dubail (LPCT, Nancy) I will briefly introduce “Generalized Hydrodynamics”, the hydrodynamic description of one-dimensional integrable systems , and review the experimental results obtained by the groups of I. Bouchoule in Palaiseau and D. Weiss in Penn State. One important experimental effect not taken into account in GHD is the atom losses : I will discuss… Read More »Hydrodynamics of the one-dimensional Bose gas : atom losses (Jerôme Dubail / LPT / Seminar). – 14/12, 14H.

Not so long ago, the concept of higher-order topological insulators and superconductors was mentioned for the first time in print (see Viewpoint ).
