论文摘要
我们提出了一种简单的现象学理论,用于基于自然的玻色子对库珀对的量子隧穿。因此,它适用于没有准粒子激发(费米)的情况下,应适用于低能量状态下的玻色子颗粒。在零偏置电压左右,我们的模型揭示了迅速饱和的隧穿电流的迅速增加。这表现为零偏置电导峰,这在很大程度上取决于超导体过渡温度。库珀对的这种低能隧穿可以作为许多隧道实验的替代解释,其中已经观察到零偏置电导峰。
We propose a simple phenomenological theory for quantum tunneling of Cooper pairs based on their boson like nature. Thus it applies in the absence of quasiparticle excitations (fermions), and should be suitable for boson like particles at the low energy regime. Around zero bias voltage our model reveals a rapid increase in tunneling current which rapidly saturates. This manifests as a zero bias conductance peak that strongly depends on the superconductors transition temperature. This low energy tunneling of Cooper pairs could serve as an alternative explanation for a number of tunneling experiments where zero bias conductance peak has been observed.
