Dynamical Phase Transitions and Instabilities in Open Atomic Many-Body Systems
Dynamical Phase Transitions and Instabilities in Open Atomic Many-Body Systems
We discuss an open driven-dissipative many-body system, in which the competition of unitary Hamiltonian and dissipative Liouvillian dynamics leads to a nonequilibrium phase transition. It shares features of a quantum phase transition in that it is interaction driven, and of a classical phase transition, in that the ordered phase is …
