Thermodynamics of quantum systems and quantum thermal machines are rapidly
develo** fields, which have already delivered several promising results, as well as raised …

The concept of inner friction, by which a quantum heat engine is unable to follow
adiabatically its strokes and thus dissipates useful energy, is illustrated in an exact physical …

We demonstrate the existence of universal features in the finite-time thermodynamics of
quantum machines by considering a many-body quantum Otto cycle in which the working …

We propose a spin-star network, where a central spin-(1/2), acting as a quantum fuel, is
coupled to N outer spin-(1/2) particles. If the network is in thermal equilibrium with a heat …

We investigate a quantum heat engine with a working substance of two particles, one with a
spin-1/2 and the other with an arbitrary spin (spin s), coupled by Heisenberg exchange …

We study work extraction from the Dicke model achieved using simple unitary cyclic
transformations kee** into account both a nonoptimal unitary protocol and the energetic …

In this work, we investigate the magnetocaloric effect for narrow nanowire quantum dot
based on spin-orbit coupling of the Rashba type. We first present an explicit expression for a …

A properly selected quantum heat engine consumes resources efficiently. Also, there are
many parameters to determine the right option. In this study, we construct and compare the …

We present two realizations of an Otto cycle with a quantum planar rotor as the working
medium controlled by means of external fields. By comparing the quantum and the classical …

A quantum thermodynamic cycle with a chiral multiferroic working substance such as LiCu 2
O 2 is presented. Shortcuts to adiabaticity are employed to achieve an efficient, finite-time …
