Shortcut- Enhanced Quantum Thermodynamics Publication 2
Emanated from research supported in part by a Grant from Science Foundation Ireland under Grant number 19/FFP/6951 (鈥淪hortcut- Enhanced Quantum Thermodynamics鈥�), our paper on 鈥淨uantum heat engine based on a spin-orbit- and Zeeman-coupled Bose-Einstein condensate鈥� has just be published in Physical Review A (Jing Li, E. Ya Sherman, and A. Ruschhaupt, 鈥淨uantum heat engine based on a spin-orbit- and Zeeman-coupled Bose-Einstein condensate鈥�, ).
In this paper, we explore the potential of a spin-orbit-coupled Bose-Einstein condensate for thermodynamic cycles. For this purpose we propose a quantum heat engine based on a condensate with spin-orbit and Zeeman coupling as a working medium. The cooling and heating are simulated by contacts of the condensate with an external magnetized media and demagnetized media. We examine the condensate ground-state energy and its dependence on the strength of the synthetic spin-orbit and Zeeman couplings and interatomic interaction. Then we study the efficiency of the proposed engine. The cycle has a critical value of spin-orbit coupling related to the engine鈥檚 maximum efficiency.
