Özet

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 a dynamic-angle spinning technique under a magnetic field. Realistic parameters are chosen for the proposed heat engine cycle. In addition, our goal is to calculate the power of the engine. To this end, we focus on the microdynamics of the quantum isothermal process to predict the required-time per engine cycle. The obtained results show that the engine has high efficiency. Furthermore, the engine attains maximum power at the same point where the maximum efficiency is satisfied.
