Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

The seminal work by Sadi Carnot in the early nineteenth century provided the blueprint of a
reversible heat engine and the celebrated second law of thermodynamics eventually …

Quantum batteries are devices made from quantum states, which store and release energy
in a fast and efficient manner, thus offering numerous possibilities in future technological …

We investigate the charging process of quantum battery (QB) systems in an extended Dicke
model with both atomic interactions and an external driving field. We focus on the effects of …

We present a collision model for the charging of a quantum battery by identical
nonequilibrium qubit units. When the units are prepared in a mixture of energy eigenstates …

Energy extraction is a central task in thermodynamics. In quantum physics, ergotropy
measures the amount of work extractable under cyclic Hamiltonian control. As its full …

We investigate the optimal charging processes for several models of quantum batteries,
finding how to maximize the energy stored in a given battery with a finite-time modulation of …

Recently, an unconditional advantage has been demonstrated for the process of charging of
a quantum battery in a collisional model [Seah et al., Phys. Rev. Lett. 127, 100601 (2021) …

Energy storage is a basic physical process with many applications. When considering this
task at the quantum scale, it becomes important to optimise the non-equilibrium dynamics of …

We propose a cavity Heisenberg-spin-chain (CHS) quantum battery (QB) with the long-
range interactions and investigate its charging process. The performance of the CHS QB is …
