Exploring entanglement effects in a quantum stirling heat engine

Abstract

This study presents the development of an entangled quantum Stirling heat engine based on a two-qubit Heisenberg model. We investigate the impact of entangled states of the working substance on the energy exchange and the performance of the Stirling cycle. The results show an improvement in the cycle's performance, which is accomplished by changing the entangled states. Furthermore, the results suggest that the operational modes of the quantum cycle can be controlled by considering changes in the entangled states of the working material and the temperatures of the reservoirs.
