Localization in disordered superconducting wires with broken spin-rotation symmetry
Ilya A. Gruzberg, N. Read, Smitha Vishveshwara
Localization and delocalization of non-interacting quasiparticle states in a superconducting wire are reconsidered, for the cases in which spin-rotation symmetry is absent, and tim…
Global entanglement and quantum criticality in spin chains
Tzu-Chieh Wei, Dyutiman Das, Swagatam Mukhopadyay +2
Entanglement in quantum XY spin chains of arbitrary length is investigated via a recently-developed global measure suitable for generic quantum many-body systems. The entanglement…
Cooper pair tunneling in junctions of singlet quantum Hall states and superconductors
Eun-Ah Kim, Smitha Vishveshwara, Eduardo Fradkin
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 p…
