Entanglement Scaling and Full Counting Statistics in Excited States of Two-Dimensional Rotating Fermions
Priyangshu Goswami, Abhishek Dhar, Satya N. Majumdar +1
We investigate the entanglement entropy of a class of -particle excited state of fermions confined in a two-dimensional harmonic trap rotating at an angular frequency . The e…
Absence of hidden analytic conserved quantities in harmonically confined rods
Sahil Kumar Singh, Abhishek Dhar, Sanjay Moudgalya
Systems of hard rods of equal length in a one-dimensional harmonic trap have been observed to exhibit peculiar non-ergodic behavior that might suggest the existence of a novel hidd…
Slow heat-driven flow in a gas of hard disks
Amit Kumar, Abhishek Dhar, Baruch Meerson
We study a slow heat-driven flow in a gas of elastically colliding hard disks confined to a long channel. The initial state consists of two regions with large temperature and densi…
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…
Hydrodynamics of the Fermi-Pasta-Ulam-Tsingou chain
Shubhadeep Chakraborty, Abhishek Dhar
We provide a pedagogical review of the hydrodynamics of the FPUT chain. There are three hydrodynamic fields corresponding to the conservation of mass, momentum and energy. We provi…
