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

Understand

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.
