Construction of a quantum Stirling engine cycle tuned by dynamic-angle spinning

Abstract

In this contribution, we investigate two coupled spins as a working substance of the quantum Stirling heat engine cycle. We propose an experimentally implementable scheme in which the cycle is driven by tuning the dipole-dipole interaction angle via dynamic-angle spinning technique in a fixed magnetic field. Realistic parameters are chosen for the proposed heat engine cycle. In addition, we aim to estimate power of the engine. To accomplish this, we focus on the microdynamics of the quantum isothermal process to predict required-time per engine cycle. The results obtained indicate that the engine produces work with high efficiency. Furthermore, the engine reaches maximum power at same point where the maximum efficiency is satisfied.
