We investigate the charging process of quantum battery (QB) systems in an extended Dicke
model with both atomic interactions and an external driving field. We focus on the effects of …

Superradiance and subradiance concerning enhanced and inhibited collective radiation of
an ensemble of atoms have been a central topic in quantum optics. However, precise …

We propose a quantum-enhanced heat engine with entanglement. The key feature of our

We study effective light-matter interactions in a circuit QED system consisting of a single LC
resonator, which is coupled symmetrically to multiple superconducting qubits. Starting from a …

We study the all-to-all connected XYZ (anisotropic-Heisenberg) spin model with local and
collective dissipations, comparing the results of mean-field (MF) theory with the solution of …
