Igor V. Ovchinnikov, Daniel Neuhauser

摘要:

导出了耦合到一个或多个导线并与之交换粒子的开放系统的类Redfield Liouville方程。该方程是在一般情况下提出的。一个案例研究的时间相关的运输通过一个单一的量子水平变化的静电和化学势的铅。对于不同的静电势的情况下,所提出的方程产量,模型研究,精确解的结果。

英文摘要:

A Redfield-like Liouville equation for an open system that couples to one or more leads and exchanges particles with them is derived. The equation is presented for a general case. A case study of time-dependent transport through a single quantum level for varying electrostatic and chemical potentials in the leads is presented. For the case of varying electrostatic potentials the proposed equation yields, for the model study, the results of an exact solution.
