We review the recent developments and the current status in the field of quantum-gas cavity
QED. Since the first experimental demonstration of atomic self-ordering in a system …

Pumps are transport mechanisms in which direct currents result from a cyclic evolution of the
potential,. As Thouless showed, the pum** process can have topological origins, when …

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 …

The interaction between an atomic ensemble and a light mode in a high-finesse optical
cavity can easily reach the strong-coupling regime, where quantum effects dominate. In this …

Coupling a system to a nonthermal environment can profoundly affect the phase diagram of
the closed system, giving rise to a special class of dissipation-induced phase transitions …

We investigate the nonequilibrium steady state of the anisotropic open quantum Rabi model,
which exhibits first-order and second-order dissipative phase transitions upon varying the …

We demonstrate the existence of finite-component multicriticality in a qubit-boson model
where biased qubits collectively coupled to a single-mode bosonic field. The interplay …

We observe a structural phase transition between two configurations of a superradiant
crystal by coupling a Bose-Einstein condensate to an optical cavity and applying …

We investigate a series of two-mode quantum batteries (QBs) which exhibits better
performance in both the stored energy and average charging power compared to the two …

We study the magnetic phases of a nonequilibrium spin chain, where coherent interactions
between neighboring lattice sites compete with alternating gain and loss processes. This …
