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…
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…
Fixed Points and Universality Classes in Coupled Kardar-Parisi-Zhang Equations
Dipankar Roy, Abhishek Dhar, Manas Kulkarni +1
We study coupled KPZ equations with three control parameters . These equations are used in the context of stretched polymers in a random medium, for the spacetime spin-spin…
Lax random matrices from Calogero systems
Jitendra Kethepalli, Manas Kulkarni, Anupam Kundu +1
We study a class of random matrices arising from the Lax matrix structure of classical integrable systems, particularly the Calogero family of models. Our focus is the density of e…
