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 …

Given the evolution of an arbitrary open quantum system, we formulate a general and
unambiguous method to separate the internal energy change of the system into an entropy …

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 …

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 …

It was recently noted that different internal quantum reference frames (QRFs) partition a
system in different ways into subsystems, much like different inertial observers in special …

We study a quantum Otto cycle that uses a 2-qubit working substance whose Hamiltonian
does not commute with itself at different times during unitary strokes. We investigate how the …

Quantum thermodynamics aims at investigating both the emergence and the limits of the
laws of thermodynamics from a quantum mechanical microscopic approach. In this scenario …

Light can be squeezed by reducing the quantum uncertainty of the electric field for some
phases. We show how to use this purely-quantum effect to extract net mechanical work from …
