- Abstract summary: We propose an efficient charging quantum battery achieved by considering an extension Dicke model with dipole-dipole interaction and an external driving field.
The maximum stored energy and maximum charging power are investigated by varying the number of atoms.
In addition, the maximum charging power approximately satisfies a superlinear scaling relation $P_rm maxvarproptobeta Nalpha$, where the quantum advantage $alpha=1.6$ can be reached via optimizing the parameters.

- Abstract: The Dicke model is a fundamental model in quantum optics, which describes the
interaction between quantum cavity field and a large ensemble of two-level
atoms. In this work, we propose an efficient charging quantum battery achieved
by considering an extension Dicke model with dipole-dipole interaction and an
external driving field. We focus on the influence of the atomic interaction and
the driving field on the performance of the quantum battery during the charging
process and find that the maximum stored energy exhibits a critical phenomenon.
The maximum stored energy and maximum charging power are investigated by
varying the number of atoms. When the coupling between atoms and cavity is not
very strong, compared to the Dicke quantum battery, such quantum battery can
achieve more stable and faster charging. In addition, the maximum charging
power approximately satisfies a superlinear scaling relation $P_{\rm
max}\varpropto\beta N^{\alpha}$, where the quantum advantage $\alpha=1.6$ can
be reached via optimizing the parameters.
