论文摘要
电子在潜在屏障上的散射或隧穿是基本的量子效应。电子电子相互作用通常会影响散射，对相互作用效应的理解对于检测各种电子传输现象及其应用于电子量子光学元件至关重要。从理论上讲，我们在量子厅制度的潜在障碍物上研究了两个相互作用的热电子的分区和碰撞。我们在屏障内部的散射延迟时间内通过库仑相互作用来预测它们的动能变化。能量变化导致分区概率与非相互作用情况的特征偏差。该派生包括概率对屏障高度的非单调依赖性，这与最近的实验一致，并减少费米子抗抗激素。
Scattering or tunneling of an electron at a potential barrier is a fundamental quantum effect. Electron-electron interactions often affect the scattering, and understanding of the interaction effect is crucial in detection of various phenomena of electron transport and their application to electron quantum optics. We theoretically study the partition and collision of two interacting hot electrons at a potential barrier in the quantum Hall regime. We predict their kinetic energy change by their Coulomb interaction during the scattering delay time inside the barrier. The energy change results in characteristic deviation of the partition probabilities from the noninteracting case. The derivation includes nonmonotonic dependence of the probabilities on the barrier height, which agrees with recent experiments, and reduction of the fermionic antibunching.
