量子系统中的非平衡涨落、涨落定理和计数统计

Nonequilibrium fluctuations, fluctuation theorems, and counting statistics in quantum systems

Massimiliano Esposito, Upendra Harbola, Shaul Mukamel

摘要:

涨落定理(FT),它描述了一些普遍的性质的非平衡涨落,从量子的角度进行检查,并通过引入一个两点测量系统导出。从一个统一的方法导出了封闭和开放系统的FT,驱动平衡的外部时间相关的力,并为开放系统保持在一个非平衡稳态的非平衡边界条件,从一个统一的方法。应用量子结中的费米子和玻色子输运进行了讨论。给出了计算能量和粒子统计的量子主方程和格林函数技术。

英文摘要:

Fluctuation theorems (FTs), which describe some universal properties of nonequilibrium fluctuations, are examined from a quantum perspective and derived by introducing a two-point measurement on the system. FTs for closed and open systems driven out of equilibrium by an external time-dependent force, and for open systems maintained in a nonequilibrium steady-state by nonequilibrium boundary conditions, are derived from a unified approach. Applications to fermion and boson transport in quantum junctions are discussed. Quantum master equations and Green's functions techniques for computing the energy and particle statistics are presented.
