# Collective effects and quantum coherence in dissipative charging of quantum batteries

@article{Mayo2022CollectiveEA, title={Collective effects and quantum coherence in dissipative charging of quantum batteries}, author={Franco Mayo and Augusto J. Roncaglia}, journal={Physical Review A}, year={2022} }

We consider the dissipative charging process of quantum batteries in terms of a collisional model, where the batteries are coupled to a heat bath using non-energy preserving interactions. First, we show that for low temperatures the collective process can attain a charging power that increases polynomically with the number of batteries. The scaling we ﬁnd is N 3 that, while being grater than the bound obtained for unitary processes, it has a lower eﬃciency. Then, we study the dissipative…
