受驱动整数量子霍尔边缘态的弛豫

Relaxation in driven integer quantum Hall edge states

D. L. Kovrizhin, J. T. Chalker

摘要:

一个高度非热的电子分布时,产生的量子霍尔边缘态源在不同的电位满足量子点接触。在最近的实验中已经观察到这种分布作为接触下游距离的函数而松弛成静止形式[Phys. Rev. Lett. 105,056803(2010)]。在这里,我们提出了一个精确的治疗的极小模型的系统填充因子为ν=2,与结果,以及帐户的观察。

英文摘要:

A highly non-thermal electron distribution is generated when quantum Hall edge states originating from sources at different potentials meet at a quantum point contact. The relaxation of this distribution to a stationary form as a function of distance downstream from the contact has been observed in recent experiments [Phys. Rev. Lett. 105, 056803 (2010)]. Here we present an exact treatment of a minimal model for the system at filling factor ν=2, with results that account well for the observations.
