Emergent Continuous Time Crystal in Dissipative Quantum Spin System
without Driving
Time crystal, a nonequilibrium phenomenon extending spontaneous symmetry breaking into the temporal dimension, holds fundamental significance in understanding quantum many-body physics. In this work, we explore the nonequilibrium phase diagram of a two-dimensional dissipative Heisenberg spin system in the absence of explicit driving. We numerically identify the emergence of novel …
