平行量子线间的霍尔效应

Hall effect between parallel quantum wires

M. Kindermann

摘要:

我们从理论上研究了Auslaender等人[Science 308,88(2005)]在低电子密度下的实验中的平行量子线。研究表明,当两条线中的一条进入小自旋带宽的自旋非相干区域时,在二维或三维电子系统中观察到的霍尔效应会发展。这与依赖于磁场的隧穿指数一起清楚地识别了这种实验中的自旋不相干性,并且将其与无序效应区分开来。

英文摘要:

We study theoretically the parallel quantum wires of the experiment by Auslaender et al. [Science 308, 88 (2005)] at low electron density. It is shown that a Hall effect as observed in two- or three-dimensional electron systems develops as one of the two wires enters the spin-incoherent regime of small spin bandwidth. This together with magnetic field dependent tunneling exponents clearly identifies spin-incoherence in such experiments and it serves to distinguish it from disorder effects.
