Coherent transfer of Cooper pairs by a movable grain
arXiv:cond-mat/0012201 · doi:10.1038/35078027
Abstract
A coherent hybrid of states with different number of Cooper pairs can be built in a superconductor grain as a result of periodically repeated discrete encounters with bulk superconductor leads. As a direct manifestation of such states a non-dissipative current depending on the phase difference between the leads can be measured.
