人们认为长手性边缘通道不能支持超导电极之间的任何超电流。我们从理论上证明，超电流可以通过非局域相互作用来介导，从而促进与电子流相反的方向上的长距离信息传输。我们计算了几种相互作用模型的超电流，包括外部电路的超电流。
It has been thought that the long chiral edge channels cannot support any supercurrent between the superconducting electrodes. We show theoretically that the supercurrent can be mediated by a nonlocal interaction that facilitates a long-distance information transfer in the direction opposite of electron flow. We compute the supercurrent for several interaction models, including that of an external circuit.
