Title Non-Abelian Statistics of Half-Quantum Vortices in p-Wave Superconductors
Speaker Kusum Dhochak
Date Mon, 31 May 2010
Time 14:30
Venue A 304


Excitation spectrum of a half-quantum vortex in a p-wave superconductor contains a zero-energy Majorana fermion. This results in a degeneracy of the ground state of the system of several vortices. From the properties of the solutions to Bogoliubov–de Gennes equations in the vortex core we derive the non-Abelian statistics of vortices identical to that for the Moore-Read (Pfaffian) quantum Hall state.
