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 atomic clocks, whether operating at optical or microwave region, can be divided into two
categories according to their working mode, namely the passive clocks and active clocks …

Any slight variations in the fundamental constants of nature, which may be induced by dark
matter or some yet-to-be-discovered cosmic field, would characteristically alter the phase of …

The Dicke model is a paradigm of collective behavior in quantum mechanics describing an
ensemble of N two-level atoms interacting with a single mode of the electromagnetic field …

We propose a system for observing the correlated phase dynamics of two mesoscopic
ensembles of atoms through their collective coupling to an optical cavity. We find a …

We investigate the collective decay dynamics of atoms with a generic multilevel structure
(angular momenta F↔ F′) coupled to two light modes of different polarization inside a …

Today's narrowest linewidth lasers are limited by mirror motion in the reference optical
resonator used to stabilize the laser's frequency. Recent proposals suggest that …

We present the non-equilibrium phase diagram of a model which can demonstrate both
Dicke–Hepp–Lieb superradiance and regular lasing by varying the coherent and incoherent …

Superradiant lasers operate in the bad-cavity regime, where the phase coherence is stored
in the spin state of an atomic medium rather than in the intracavity electric field. Such lasers …

The Dicke model is of fundamental importance in quantum mechanics for understanding the
collective behavior of atoms coupled to a single electromagnetic mode. Here, we …
