We propose a gradient-based general computational framework for optimizing model-
dependent parameters in quantum batteries (QB). We apply this method to two different …

We consider a micromaser model of a quantum battery, where the battery is a single mode
of the electromagnetic field in a cavity, charged via repeated interactions with a stream of …

We discuss the idea of extracting energy stochastically from a quantum battery, which is
based on performing a projective measurement on an auxiliary system. The battery is …

This study examines the performance of finite spin quantum batteries (QBs) using
Heisenberg spin models with Dzyaloshinsky-Moriya (DM) and Kaplan--Shekhtman--Entin …

Energy extraction from quantum batteries by means of completely positive trace-preserving
(CPTP) maps leads to the concept of CPTP-local passive states, which identify bipartite …

We investigate the performance of the Lipkin-Meshkov-Glick quantum battery based on
shortcuts to adiabaticity (STA). We mainly consider the situation where the coupling strength …

We investigate the role of catalysts in energy extraction from quantum batteries. Two basic
classes of catalysts are proposed in this regard, viz., energy-and state-invariant catalysts …

We extend the concept of stochastic energy extraction from quantum batteries to the
scenario where both positive operator-valued (POV) and physically realizable non-positive …

Quantum battery concerns about population redistribution and energy dispatch over
controllable quantum systems. Under unitary transformation, ergotropy rather than energy …

Parity-time (PT) symmetric quantum theory can broaden the scope of quantum dynamics
beyond unitary evolution which may lead to numerous counterintuitive phenomena …
