Cooper pair tunneling in junctions of singlet quantum Hall states and superconductors
arXiv:cond-mat/0405156 · doi:10.1103/PhysRevLett.93.266803
Abstract
We propose tunnel junctions of a Hall bar and a superconducting lead, for observing Cooper-pair tunneling into singlet fractional quantum Hall edge states. These tunnel junctions provide a natural means of extracting precise information of the spin polarization and the filling factor of the state. The low energy regime of one of the set-ups is governed by a novel quantum entangled fixed point.
