玻色化失平衡

Bosonization out of equilibrium

D. B. Gutman, Yuval Gefen, A. D. Mirlin

摘要:

我们发展了一种玻色化技术来处理一维非平衡费米子。该方法被用来研究一个量子线连接到两个电极与任意的能量分布。非平衡电子格林函数表示在一个单粒子"计数“运营商与时间相关的散射相位的功能行列式。结果揭示了在Luttinger液体中的失相和能量再分配与隧穿过程中和与铅的边界处的电子-空穴激发的“分馏”的内在关系。

英文摘要:

We develop a bosonization technique for one-dimensional fermions out of equilibrium. The approach is used to study a quantum wire attached to two electrodes with arbitrary energy distributions. The non-equilibrium electron Green function is expressed in terms of functional determinants of a single-particle``counting'' operator with a time-dependent scattering phase. The result reveals an intrinsic relation of dephasing and energy redistribution in Luttinger-liquids to ``fractionalization'' of electron-hole excitations in the tunneling process and at boundaries with leads.
