We consider the optimization of a finite-time Carnot engine characterized by small
dissipations. We bound the power with a simple inequality and show that the optimal …

Thermodynamics is a branch of science blessed by an unparalleled combination of
generality of scope and formal simplicity. Based on few natural assumptions together with …

An implementation of quantum absorption chillers with three qubits has been recently
proposed that is ideally able to reach the Carnot performance regime. Here we study the …

The energy selective electron device works among electron reservoirs with different
temperatures and chemical potentials. Electrons obey the Fermi-Dirac distribution, and with …

Isothermal transformations are minimally dissipative but slow processes, as the system
needs to remain close to thermal equilibrium along the protocol. Here, we show that …

When a Brownian particle in contact with a heat bath at a constant temperature is controlled
by a time-dependent harmonic potential, its distribution function can be rigorously derived …

Combining finite time thermodynamics and exergetic analysis, analogous to the definition of
ecological efficient power for heat engines, this paper proposes a unified performance …

We study the optimal performance of Carnot-like heat engines working in the low-dissipation
regime using the product of the efficiency and the power output, also known as the efficient …

The performance of a quantum Otto refrigerator coupled to a squeezed cold reservoir has
been evaluated using the χ figure of merit. We have shown that squeezing can enhance the …

We apply a unified and trade-off based optimization for low-dissipation models of cyclic heat
devices which accounts for both useful energy and losses. The resulting performance …
