通常，依赖时间的热力学协议需要渐进缓慢地运行以避免耗散损失。通过将反绝热驱动和 Floquet 工程的思想应用于开放系统，我们开发了快进协议，用于快速热化局部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，以引起系统和浴之间的共振状态交换。我们应用快进协议来实现快速近似奥托发动机在接近卡诺效率的高功率下运行。我们的结果提出了耦合多体系统中快速冷却协议的设计原则。
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.
