多束缚模量子Hall反点中的旁观者行为

Spectator Behavior in a Quantum Hall Antidot with Multiple Bound Modes

W. -R. Lee, H. -S. Sim

摘要:

我们从理论上研究了在整数量子霍尔制度中具有多个束缚模式的反点系统中的Aharonov-Bohm共振,考虑了模式之间的电容相互作用。我们发现旁观者的行为,一些模式的共振消失,而不是由其他模式,由于模式之间的内部电荷弛豫取代。这种行为是一个可能的起源以前的实验数据仍然无法解释的功能,观众的行为在antidot分子和共振在一个单一的antidot与三种模式。

英文摘要:

We theoretically study Aharonov-Bohm resonances in an antidot system with multiple bound modes in the integer quantum Hall regime, taking capacitive interactions between the modes into account. We find the spectator behavior that the resonances of some modes disappear and instead are replaced by those of other modes, due to internal charge relaxation between the modes. This behavior is a possible origin of the features of previous experimental data which remain unexplained, spectator behavior in an antidot molecule and resonances in a single antidot with three modes.
