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 …

Quantum dynamical maps provide suitable mathematical representation of quantum
evolutions. When representing quantum states by density operators, the evident …

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 …

We show that a micromaser is an excellent model of quantum battery. A highly excited, pure,
and effectively steady state of the cavity mode, charged by coherent qubits, can be achieved …

The dynamics of quantum systems unfolds within a subspace of the state space or operator
space, known as the Krylov space. This review presents the use of Krylov subspace …

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

Understanding and simulating how a quantum system interacts and exchanges information
or energy with its surroundings is a ubiquitous problem, one which must be carefully …

A longstanding tool to characterize the evolution of open Markovian quantum systems is the
GKSL (Gorini-Kossakowski-Sudarshan-Lindblad) master equation. However, in some cases …

Strong local disorder in interacting quantum spin chains can turn delocalized eigenmodes
into localized eigenstates, giving rise to many-body localized phases. This is accompanied …

The amount of work that can be extracted from a quantum system can be increased by
exploiting the information obtained from a measurement performed on a correlated ancillary …
