Research Pursuits 【 display / non-display

  • Due to the recent development of experimental techniques of cold atomic systems trapped by laser it has now become possible to compare many theoretical results of integrable quantum systems such as the 1D Bose gas with experiments of one dimensional trapped atomic systems. The non-equilibrium dynamics of integrable qunatum many-body systems have attracted much interest also from fundamental aspects of quantum statistical mecahnics such as ergodicity and thermalization of isolated quantum systems, and typicality of quantum sates.
