Dean-Kawasaki fluctuating hydrodynamics for backscattering hard rods
Mrinal Jyoti Powdel
We study a system of backscattering hard rods in one dimension. Contrary to the usual ballistic hard rods, these hard rods flip the sign of their velocities with a rate . This…

Uncertainty Growth in Stably Stratified Turbulence
Mrinal Jyoti Powdel, Samriddhi Sankar Ray
We investigate uncertainty growth and chaotic dynamics in statistically steady, stably stratified three-dimensional turbulence. Using direct numerical simulations of the Boussinesq…

Conserved densities of hard rods: microscopic to hydrodynamic solutions
Mrinal Jyoti Powdel, Anupam Kundu
We consider a system of many hard rods moving in one dimension. As it is an integrable system, it possesses an extensive number of conserved quantities and its evolution on macrosc…
