We study the ecological regime of quantum heat engines where the heat transfer between
the environment and the engine is mediated with two qubits that act as energy filters and …

We consider optimizations of Lenoir engine within a quantum dynamical field consisting of N
noninteracting fermions trapped in multilevel infinite potential square-well. Fermions play a …

We study the similarities and differences between one-qubit Novikov quantum heat engines
and classic Novikov heat engines. We find that they have similar power-efficiency curves but …

We examine a quantum Otto engine using both Bose–Einstein condensation (BEC) and
normal Bose gas as working medium trapped in generalized external potential. We treated …

We consider the toy model of quantum Diesel cycle without temperature constructed from
non-interacting fermions, which are trapped in a one-dimensional box. The work and energy …

We consider the toy model of quantum Brayton cycle, constructed from non-interacting
fermions, trapped in a one-dimensional box. We use all energy levels of the box. The work …

Since the beginning of the quantum era, physicists have tried to find various interrelated
connections between classical physics and quantum physics, including the relevance of …

Enhancing the efficiency of quantum heat engines (QHEs) is crucial for advancing
fundamental research and quantum technology. We here we explore a quantum Stirling …

We investigate the phenomenon of partial thermalization in the context of the efficiency at
maximum power (EMP) for a quantum Otto engine. This engine utilizes Bose-Einstein …

The potential well is a simple example that generally used to present an understanding of
quantum mechanics. In this article, we used infinite spherical well model to evaluate the …
