The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

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

Quantum multicriticality not only has fundamental research significance but also can
promote the development of emerging quantum technologies, owing to its rich phase …

We report on the experimental realization and detection of dynamical currents in a spin-
textured lattice in momentum space. Collective tunneling is implemented via cavity-assisted …

The coupling of ultracold quantum gases to an optical cavity provides an ideal system for
studying the novel long-range interacting nonequilibrium dynamics. Here we report an …

We investigate the three-level Dicke model, which describes a fundamental class of light-
matter systems. We determine the phase diagram in the presence of dissipation, which we …

We demonstrate the formation of a condensate in a dark state of momentum states, in a
pumped and shaken cavity-BEC system. The system consists of an ultracold quantum gas in …

Many-body cavity QED experiments are established platforms to tailor and control the
collective responses of ensembles of atoms, interacting through one or more common …

A quantum battery (QB) is an energy storage and extraction device that is governed by the
principles of quantum mechanics. Here we propose a three-level Dicke QB and investigate …

We describe a method to create and store scalable and long-lived entangled spin-squeezed
states within a manifold of many-body cavity dark states using collective emission of light …
