整数量子Hall系统的弛豫和边缘重构

Relaxation and edge reconstruction in integer quantum Hall systems

Torsten Karzig, Alex Levchenko, Leonid I. Glazman, Felix von Oppen

摘要:

限制势和电子-电子相互作用之间的相互作用导致量子霍尔边缘的重建。我们研究的后果,这种边缘重建的弛豫热电子注入整数量子霍尔边缘状态。在非线性不变的边缘,热电子的弛豫是由三体碰撞,这是敏感的电子色散,从而重建效果。我们表明,在不同的重建方案的松弛率显着改变。

英文摘要:

The interplay between the confinement potential and electron-electron interactions causes reconstructions of Quantum Hall edges. We study the consequences of this edge reconstruction for the relaxation of hot electrons injected into integer quantum Hall edge states. In translationally invariant edges, the relaxation of hot electrons is governed by three-body collisions which are sensitive to the electron dispersion and thus to reconstruction effects. We show that the relaxation rates are significantly altered in different reconstruction scenarios.
