Alexander Croy, Ulf Saalmann

摘要:

导出了描述含时电子输运的封闭耦合运动方程组。它提供了从非平衡格林函数构造的能量分辨量的时间演化。通过一个非线性模式扩展的可行的传播计划有限的温度,它允许研究任意的时间依赖性和结构化的水库。两个示例。

英文摘要:

A closed set of coupled equations of motion for the description of time-dependent electron transport is derived. It provides the time evolution of energy-resolved quantities constructed from non-equilibrium Green functions. By means of an auxiliary-mode expansion a viable propagation scheme for finite temperatures is obtained, which allows to study arbitrary time dependences and structured reservoirs. Two illustrative examples are presented.
