Comment on “Loss-Free Excitonic Quantum Battery” Tejero, Álvaro Manzano Diosdado, Daniel Quantum batteries have primarily been modeled as an ensemble of isolated systems that store energy and from which work can be extracted by applying unitary transformations. 1 Only recently have investigations begun in the direction of dissipative quantum batteries2−4 wherein the charge of the battery is protected against a dissipative environment. 2022-02-11T09:26:37Z 2022-02-11T09:26:37Z 2021-03-25 journal article J.
