Quasiparticle Diffusion for the Toda Fluid in Equilibrium
Seema Chahal, Alberto Brollo, Indranil Mukherjee +3
Many-body integrable systems can be understood as a gas of quasiparticles. They propagate ballistically and drive large-scale transport. However, with the exception of the hard rod…
Microscopic and hydrodynamic correlation in 1d hard rod gas
Indranil Mukherjee, Seema Chahal, Anupam Kundu
We compute mass density correlations of a one-dimensional gas of hard rods at both microscopic and macroscopic scales. We provide exact analytical calculations of the microscopic c…
Stochastic dynamics of quasiparticles in the hard rod gas
Seema Chahal, Indranil Mukherjee, Abhishek Dhar +2
We consider a one-dimensional gas of hard rods, one of the simplest examples of an interacting integrable model. It is well known that the hydrodynamics of such integrable models c…
