摘要
Transport of electron pairs in a superconducting junction device with spatiotemporal noise is investigated. It is shown that, in a superconducting junction device, spatiotemporal noise can appear and induce a nonzero current due to the symmetry breaking induced by the correlation of the spatiotemporal noise with the phase difference. We found that there is a negative current for the electron pairs, exhibiting a well with increasing thermal noise strength. Our results can provide a theoretical foundation for the further investigation of superconducting junctions.
