论文摘要
我们考虑了整数量子厅策略中的电子hong-ou-mandel干涉仪，在该量子量霍尔制度中，碰撞电子状态是通过将电压脉冲（例如创建Levitons）应用于欧姆触点而产生的。这项工作的目的是研究可能的机制，导致Pauli DIP的可见性降低，即对同步源预期的噪声抑制。众所周知，电子 - 电子相互作用无法解释这种效果，并且始终导致对洪 - 曼德尔噪声的完全抑制。为了关注填充因子$ν= 2 $的情况，我们表明，Pauli DIP的可见度降低可能是由于它们之间的隧道事件引起的，可以由共同磁边的混合而产生。
We consider an electronic Hong-Ou-Mandel interferometer in the integer quantum Hall regime, where the colliding electronic states are generated by applying voltage pulses (creating for instance Levitons) to ohmic contacts. The aim of this work is to investigate possible mechanisms leading to a reduced visibility of the Pauli dip, i.e., the noise suppression expected for synchronized sources. It is known that electron-electron interactions cannot account for this effect and always lead to a full suppression of the Hong-Ou-Mandel noise. Focusing on the case of filling factor $ν=2$, we show instead that a reduced visibility of the Pauli dip can result from mixing of the copropagating edge channels, arising from tunneling events between them.
