简并本征态相干的量子热力学

Quantum Thermodynamics with Degenerate Eigenstate Coherences

Gregory Bulnes Cuetara, Massimiliano Esposito, Gernot Schaller

摘要:

当系统呈现简并时,我们建立了弱耦合到其库的开放量子系统的量子热力学。推导出热力学第一和第二定律,以及机械功、能量和物质流的有限时间涨落定理。利用双量子点结模型,局域本征基相干性在热力学和电子计数统计中起着至关重要的作用。

英文摘要:

We establish quantum thermodynamics for open quantum systems weakly coupled to their reservoirs when the system exhibits degeneracies. The first and second law of thermodynamics are derived, as well as a finite-time fluctuation theorem for mechanical work and energy and matter currents. Using a double quantum dot junction model, local eigenbasis coherences are shown to play a crucial role on thermodynamics and on the electron counting statistics.
