量子霍尔边沟道中单电子激发的退相干和弛豫

Decoherence and relaxation of single electron excitations in quantum Hall edge channels

Pascal Degiovanni, Charles Grenier, Gwendal Fève

摘要:

本文提出了一种计算双量子霍尔边沟道中能量分辨单电子激发的退相干和弛豫的统一方法。在玻色化框架内,计算了由相互作用和与外部线性电路的电容耦合引起的弛豫和退相干。本文建立了一个由边沟道和线性电路构成的两端器件高频输运特性的显式连接。

英文摘要:

A unified approach to decoherence and relaxation of energy resolved single electron excitations in Integer Quantum Hall edge channels is presented. Within the bosonization framework, relaxation and decoherence induced by interactions and capacitive coupling to an external linear circuit are computed. An explicit connexion with high frequency transport properties of a two terminal device formed by the edge channel on one side and the linear circuit on the other side is established.
