SUMMARY:Structure formation in scalar active matter - Mike Cates (Universi

DESCRIPTION:I will address the spontaneous formation of structure\, includ
 ing layers\, in diffusive active particles without alignment interactions.
  These can described in terms of a scalar density field with diffusive dyn
 amics\, and also in some cases\, birth/death dynamics.&nbsp\;Such density 
 fields are governed by stochastic PDEs where the noise stems from the unde
 rlying microscopic motion. For active systems this motion need not obey de
 tailed balance conditions\, so that that the noiseless evolution is not in
  general a gradient flow\, allowing a wider variety of behaviour than in p
 assive systems close to thermal equilibrium\, for which it is. In neither 
 case is linear diffusive instability of the uniform state (aka antidiffusi
 on) a prerequisite for structure formation\; the alternative is noise-indu
 ced nucleation of the structured state.
