Real-time broadening of nonequilibrium density profiles and the role of the specific initial-state realization
Real-time broadening of nonequilibrium density profiles and the role of the specific initial-state realization
The real-time broadening of density profiles starting from nonequilibrium states is at the center of transport in condensed-matter systems and dynamics in ultracold atomic gases. Initial profiles close to equilibrium are expected to evolve according to the linear response, e.g., as given by the current correlator evaluated exactly at equilibrium. …
