Phys. Rev. Lett. 93, 266803 (2004) [4 pages]Cooper-Pair Tunneling in Junctions of Singlet Quantum Hall States and SuperconductorsReceived 7 May 2004; published 20 December 2004 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 setups is governed by a novel quantum entangled fixed point. © 2004 The American Physical Society URL:
