We theoretically investigate a quantum heat diode based on two interacting flux qubits
coupled to two heat baths. Rectification of heat currents is achieved by asymmetrically …

As previously demonstrated, the entropy production—a key quantity characterizing the
irreversibility of thermodynamic processes—is related to generation of correlations between …

Entanglement engines are autonomous quantum thermal machines designed to generate
entanglement from the presence of a particle current flowing through the device. In this work …

We study intraenvironmental classical and quantum correlations in a thermal machine,
which is modeled as a driven quantum system coupled with thermal reservoirs. We compute …

We present the exact theory of quantum engines whose working medium is a network of
driven oscillators performing an arbitrary cyclic process while coupled to thermal and …

We propose a practical implementation of a two-qubit entanglement engine which denotes a
scheme to generate quantum correlations through purely dissipative processes. On a …

The quantum entanglement between the coin state and the position in nonlinear quantum

We propose a solid state thermal machine based on quantum dots to generate steady-state
entanglement between distant spins. Unlike previous approaches our system can be …

We put forward four schemes of a coupled-qubit quantum Otto machine, a generalization of
the single-qubit quantum Otto machine, based on work and heat transfer between an …

We use the theory of open quantum systems to study quantum thermal machines, deriving
their master equations to understand how they evolve in time. We consider three different …
