Synthetic Berry curvature in atom-cavity systems
Zheng Tang, Rui-Lin Zhang, Xiaotian Nie +2
In atom-cavity systems, mean field theory is widely used, in which the quantum cavity operator is replaced by a classical amplitude. Then the problem is converted into atoms moving…
Non-adiabatic linear response in open quantum systems
Xiaotian Nie, Wei Zheng
Adiabatic theorem and non-adiabatic corrections have been widely applied in modern quantum technology. Recently, non-adiabatic linear response theory has been developed to probe th…
Fate of the spatial-temporal order under quantum fluctuation
Xiaotian Nie, Wei Zheng
In a previous theoretical work [arXiv:2205.01461], T. Esslinger group proposed a scheme to realize a spatial-temporal lattice, which possesses dual periodicity on space and time, i…
Non-equilibrium phases of Fermi gas inside a cavity with imbalanced pumping
Xiaotian Nie, Wei Zheng
In this work, we investigate the non-equilibrium dynamics of one-dimensional spinless fermions loaded in a cavity with imbalanced pumping lasers. Our study is motivated by previous…
Mode softening in time-crystalline transitions of open quantum systems
Xiaotian Nie, Wei Zheng
In this work, we generalize the concept of roton softening mechanism of spatial crystalline transition to time crystals in open quantum systems. We study a dissipative Dicke model…
