Boundary Time Crystals Induced by Local Dissipation and Long-Range Interactions
Zhuqing Wang, Ruochen Gao, Xiaoling Wu +4
Driven-dissipative many-body system supports nontrivial quantum phases absent in equilibrium. As a prominent example, the interplay between coherent driving and collective dissipat…
