Linear dynamical stability of hydrodynamics and the laws of thermodynamics

• Blaise Goutéraux

The low energy dynamics of interacting systems are described at late times and long distances by hydrodynamics. I will show that hydrodynamic theories are dynamically stable under linear perturbations provided the system is locally thermodynamically stable and the second law of thermodynamics is obeyed.

Poincaré et ses limites

• Marios Petrolopoulos

The Poincaré group is at the heart of Einstein's description of spacetime. Its non-relativistic limit, the Galilean group, is adapted to physics at velocities that are small compared with the speed of light. There is another limit, called the Carrollian limit, obtained formally as a zero-speed-of-light limit. Despite its exotic nature, this limit has found a vast field of applications in the study of the asymptotic symmetries of certain types of spacetimes, in the description of the horizons of black holes, and in the formulation of the ultra-relativistic limit of fluids.

Freezing phase transitions in lattice models and toy-models of quasicrystals

• Jean-René Chazottes

Surprisingly, the understanding of simple models within the framework of classical lattice statistical mechanics, which exhibit a phase transition between a disordered phase and an ordered (crystalline or quasi-crystalline) phase, has only progressed recently, notably through the use of ideas from dynamical systems. I will attempt to put things into perspective and discuss some very recent results.
