SUMMARY:LPTMS Seminar: Léo Touzo - CNRS candidate - Salle des séminaires 
 du FAST et du LPTMS\, bâtiment Pascal n°530 - 3 Nov 26 11:00
DESCRIPTION:Wave turbulence in odd fluids and odd solids\nLéo Touzo (Unive
 rsity of Chicago)\n&nbsp\;\n\nWeakly non-linear physical systems which sup
 port the propagation of waves may exhibit a phenomenon called wave turbule
 nce (by analogy with the well-known hydrodynamic turbulence)\, characteriz
 ed by a flux across scales of one or more conserved quantities (such as th
 e energy). These so-called turbulent cascades are by definition out of equ
 ilibrium phenomena\, which require forcing and dissipation at separated sc
 ales. They may arise in systems as diverse as water surfaces\, the atmosph
 ere\, plasmas\, elastic plates\, or Bose-Einstein condensates. In this tal
 k\, I will consider situations in which such a turbulent cascade develops 
 on top of a driven-dissipative steady-state\, which is already out of equi
 librium in the absence of forcing. I will focus on chiral active media\, i
 n which waves arise as a consequence of non-reciprocal responses known as 
 odd viscosity and odd elasticity. Through a combination of analytical and 
 numerical results\, I will show how odd viscous fluids and odd elastic sol
 ids may both exhibit wave turbulent cascades with unique properties. In th
 e case of the odd solid\, this occurs despite the energy not being conserv
 ed by the medium\, the cascading quantity being instead a new emergent con
 served quantity of the system.
