DOI: 10.1088/1367-2630/ab91fc
Abstract: We consider a quantum battery modeled as a set of $N$ independent two-level quantum systems driven by a time dependent classical source. Different figures of merit, such as stored energy, time of charging and energy… read more here.

DOI: 10.1103/physreve.106.054119
Abstract: A generalized collision model is developed to investigate coherent charging a single quantum battery by repeated interactions with many-atom large spins, where collective atom operators are adopted and the battery is modeled by a uniform… read more here.

DOI: 10.3390/e24121821
Abstract: A quantum battery consisting of an ensemble two-level atom is investigated. The battery is charged simultaneously by a harmonic field and an electrostatic field. The results show that the hybrid charging is superior to the… read more here.
