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…

Thermalization and hydrodynamics in an interacting integrable system: the case of hard rods
Sahil Kumar Singh, Abhishek Dhar, Herbert Spohn +1
We consider the relaxation of an initial non-equilibrium state in a one-dimensional fluid of hard rods. Since it is an interacting integrable system, we expect it to reach the Gene…

Entropy of hard square lattice gas with distinct species of particles: coloring problems and vertex models
Sahil Kumar Singh, Sudhir R. Jain
Coloring the faces of 2-dimensional square lattice with distinct colors such that no two adjacent faces have the same color is considered by establishing connection between the…
