Generalized hydrodynamics in strongly interacting 1D Bose gases

Abstract

Monitoring quantum dynamics Reducing the dimensionality of a quantum system of interacting particles can simplify its physics. Such reduction is possible in ultracold atomic gases, where a lattice of one-dimensional (1D) gases can be generated using optical potentials. Malvania et al . studied the dynamics of 1D rubidium-87 atomic gases after a sudden increase in the axial trapping potential. Normally, these dynamics would be difficult to describe theoretically, but the researchers found that a theory called generalized hydrodynamics captured the behavior of their 1D system over a long time evolution. —JS
