Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Quasiprobabilities are mathematical quantities describing the statistics of measurement
outcomes evaluated at two or more times, which incorporate the incompatibility of the …

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 …

We investigate the performance of a one-dimensional dimerized XY chain as a spin
quantum battery. Such integrable model shows a rich quantum phase diagram that emerges …

Nonreciprocity, arising from the breaking of time-reversal symmetry, has become a
fundamental tool in diverse quantum technology applications. It enables directional flow of …

We propose and analyze a universal method to obtain fast charging of a quantum battery by
a driven charger system using controlled, pure dephasing of the charger. While the battery …

We introduce a cyclic quantum battery QB model, based on an interacting bipartite system,
weakly coupled to a thermal bath. The working cycle of the battery consists of four strokes …

Quantum battery (QB) is an energy storage and extraction device conforming to the
principles of quantum mechanics. In this study, the characteristics of QBs are considered for …

A scheme for quantum batteries consisting of an atom‐cavity interacting system under a
structured reservoir in the non‐Markovian regime is proposed. A multi‐parameter regime for …
