开放量子系统中快进驱动的快速传热

Swift heat transfer by fast-forward driving in open quantum systems

Tamiro Villazon, Anatoli Polkovnikov, Anushya Chandran

摘要:

通常,时间依赖的热力学协议需要渐近缓慢地运行,以避免耗散损失。通过将反非绝热驱动和Floquet工程的想法应用于开放系统,我们开发了快速转发协议,用于快速热化本地耦合到光学声子浴的系统振荡器。这些协议控制系统频率和系统-浴耦合以诱导系统和浴之间的共振状态交换。我们应用快速前进的协议,以实现一个快速的近似奥托发动机工作在高功率附近的卡诺效率。我们的研究结果表明,快速冷却协议耦合多体系统的设计原则。

英文摘要:

Typically, time-dependent thermodynamic protocols need to run asymptotically slowly in order to avoid dissipative losses. By adapting ideas from counter-diabatic driving and Floquet engineering to open systems, we develop fast-forward protocols for swiftly thermalizing a system oscillator locally coupled to an optical phonon bath. These protocols control the system frequency and the system-bath coupling to induce a resonant state exchange between the system and the bath. We apply the fast-forward protocols to realize a fast approximate Otto engine operating at high power near the Carnot Efficiency. Our results suggest design principles for swift cooling protocols in coupled many-body systems.
