DESCRIPTION:Recently developed generalised hydrodynamic theory has been qu
 ite successful in understanding non-equilibrium evolution in integrable sy
 stems like hard rods which do not relax to Gibbs state. For hard rod gas\,
  I will discuss hydrodynamic evolution from certain non-equilibrium states
  and demonstrate if and when they approach generalised Gibbs state. I will
  also discuss how to see the effect of dissipation in such evolution. In t
 he second part of my presentation\, I will talk about what happens when th
 e microscopic integrability is broken by trapping the hard rods inside a c
 onfining potential. Particularly\, I will discuss the possibility of chaos
 \, ergodicity and thermalisation in &nbsp\;trapped hard rods. Understandin
 g these properties of trapped integrable systems has recently drawn a lot 
 of interest.
