Dynamics of ultracold quantum gases in the dissipative Fermi–Hubbard model

Abstract

We employ metastable ultracold $^{173}$Yb atoms to study dynamics in the 1D\ndissipative Fermi-Hubbard model experimentally and theoretically, and observe a\ncomplete inhibition of two-body losses after initial fast transient dynamics.\nWe attribute the suppression of particle loss to the dynamical generation of a\nhighly entangled Dicke state. For several lattice depths and for two- and\nsix-spin component mixtures we find very similar dynamics, showing that the\ncreation of strongly correlated states is a robust and universal phenomenon.\nThis offers interesting opportunities for precision measurements.\n
