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 quantum battery (QB) makes use of quantum effects to store and supply energy, which
may outperform its classical counterpart. However, there are two challenges in this field. One …

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 propose to use a quantum spin chain as a device to store and release energy coherently
and we investigate the interplay between its internal correlations and outside decoherence …

Quantum battery (QB) is the miniature energy storage and release device and plays a
crucial role in future quantum technology. Here an implementation scheme of a QB is …

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 …

We study the problem of charging a dissipative one-dimensional XXX spin-chain quantum
battery using local magnetic fields in the presence of spin decay. The introduction of …

We investigate the steady-state charging process of a single-cell quantum battery
embedded in an N-cell star network of qubits, each interacting with a fermion reservoir …

Energy can be stored in quantum batteries by electromagnetic fields as chargers. In this
paper, the performance of a quantum battery with single and double chargers is studied. It is …

We demonstrate an asymmetry between the beneficial effects one can obtain using nonlocal
operations and nonlocal states to mitigate the detrimental effects of environmental noise in …
