Tunneling Rate in Chaotic Quantum System

摘要

We study spectrum properties of electron tunneling in isolated double quantum wells (DQWs) in relation to the geometry variations of the DQW shapes. The tunneling rate in DQW with chaotic and regular geometry was considered. The calculations presented do not support the recent proposed assumption about the regularization of the tunneling rate when the QW geometry in DQW is chaotic. We confirm the strong influence of the geometry of QW boundaries on the fluctuation of tunneling rate along the electron spectrum.
