Blast in a One-Dimensional Cold Gas: From Newtonian Dynamics to Hydrodynamics
Blast in a One-Dimensional Cold Gas: From Newtonian Dynamics to Hydrodynamics
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 problem, and precise numerical demonstrations of the equivalence of the hydrodynamic and microscopic descriptions are rare. We test this equivalence in the context …
