Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

The Dicke model describes the coupling between a quantized cavity field and a large
ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can …

The rate at which matter emits or absorbs light can be modified by its environment, as
markedly exemplified by the widely studied phenomenon of superradiance. The reverse …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Discrete time crystals are a recently proposed and experimentally observed out-of-
equilibrium dynamical phase of Floquet systems, where the stroboscopic dynamics of a local …

We establish a link between metastability and a discrete time-crystalline phase in a
periodically driven open quantum system. The mechanism we highlight requires neither the …

We demonstrate that the open quantum Rabi model (QRM) exhibits a second-order
dissipative phase transition (DPT) and propose a method to observe this transition with …

The superradiant phase transition (SPT) has been widely studied in cavity quantum
electrodynamics (CQED). However, this SPT is still subject to ongoing debates due to the no …

Open quantum Dicke models are paradigmatic systems for the investigation of light-matter
interaction in out-of-equilibrium quantum settings. Albeit being structurally simple, these …

We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel
multicriticality in a cavity quantum electrodynamics system, where a two-level atom interacts …
