Thermalization, Chaos and Hydrodynamics in Classical Hamiltonian Systems
Santhosh Ganapa
We will discuss various aspects of thermalization, chaos and hydrodynamics in one dimensional classical Hamiltonian systems. We study two problems. First, we will revisit the Fermi…
Quasiperiodicity in the Fermi-Pasta-Ulam-Tsingou problem revisited: an approach using ideas from wave turbulence
Santhosh Ganapa
The Fermi-Pasta-Ulam-Tsingou (FPUT) problem addresses fundamental questions in statistical physics, and attempts to understand the origin of recurrences in the system have led to m…
Blast in a One-Dimensional Cold Gas: From Newtonian Dynamics to Hydrodynamics
Subhadip Chakraborti, Santhosh Ganapa, P. L. Krapivsky +1
A gas composed of a large number of atoms evolving according to Newtonian dynamics is often described by continuum hydrodynamics. Proving this rigorously is an outstanding open pro…
The Taylor-von Neumann-Sedov blast-wave solution: comparisons with microscopic simulations of a one-dimensional gas
Santhosh Ganapa, Subhadip Chakraborti, P. L. Krapivsky +1
We study the response of an infinite system of point particles on the line initially at rest on the instantaneous release of energy in a localized region. We make a detailed compar…
Thermalization of local observables in the -FPUT chain
Santhosh Ganapa, Amit Apte, Abhishek Dhar
Most studies on the problem of equilibration of the Fermi-Pasta-Ulam-Tsingou (FPUT) system have focused on equipartition of energy being attained amongst the normal modes of the co…
