Description:
Author(s): Jan Carl Budich and Markus Heyl We introduce a topological quantum number—coined dynamical topological order parameter (DTOP)—that is dynamically defined in the real-time evolution of a quantum many-body system and represented by a momentum space winding number of the Pancharatnam geometric phase. Our construction goes conceptuall… [Phys. Rev. B 93, 085416] Published Wed Feb 10, 2016
