Özet

We propose and investigate the implementable quantum heat engine cycle via tuning the dipole-dipole interaction strength in NMR-like setups with the low magnetic field. The nuclear spins of interacting H1 and C13 isotopes are considered as a realistic model. The cycle control procedure is provided by the finite-time driving the angle between vector connected two spins and the external static magnetic field in quantum adiabatic strokes. We observe that the almost frictionless region where the cycle operates as a heat engine with maximum power can be created in the considered realistic parameter range. Lastly, we make an estimation of thermalization times in the quantum isochoric strokes due to dipole-dipole relaxation.
