Low-energy effective theory of non-thermal fixed points in a multicomponent Bose gas

26 Jul 2018Aleksandr N. MikheevChristian-Marcel SchmiedThomas Gasenzer

Non-thermal fixed points in the evolution of a quantum many-body system quenched far out of equilibrium manifest themselves in a scaling evolution of correlations in space and time. We develop a low-energy effective theory of non-thermal fixed points in a bosonic quantum many-body system by integrating out long-wave-length density fluctuations... (read more)
