Quantum Otto and Carnot engines have recently been receiving attention due to their ability
to achieve high efficiencies and powers based on the laws of quantum mechanics. This …

We propose an approach for the optimization of the charging of harmonic oscillators
(quantum batteries) coupled to a harmonic oscillator (charger), driven by a laser field. We …

We investigate the non-equilibrium thermodynamics of pure decoherence. In a pure
decoherence process, the system Hamiltonian is a constant of motion and there is no direct …

The possibility of efficiently converting heat into work at the microscale has triggered an
intense research effort to understand quantum heat engines, driven by the hope of quantum …

We study the possibility of deterministic protocols for extracting work from quantum systems.
Focusing on the two-point measurement work extraction scenario, we prove that, with …

Navigating the intricacies of thermal management at the quantum scale is a challenge in the
pursuit of advanced nanoscale technologies. To this extent, theoretical frameworks …

In this paper, we give a computational approach of work and heat for any quantum systems.
We use the strategy that the part of energy exchange with the von Neumann entropy …

We investigate the dynamics of ergotropy in open systems under Markovian and non-
Markovian evolutions. In this scenario, we begin by formulating the ergotropy of an arbitrary …

Dealing with a generic time-local non-Markovian master equation, we define current and
power to be process-dependent as in classical thermodynamics. Each process is …

We compare definitions of the internal energy of an open quantum system and strategies to
split the internal energy into work and heat contributions as given by four different …
