Confined topological superconductors host novel chiral states

Wed, 12/27/2017 - 12:54
Topological superconductivity is an interesting state of matter, partly because it is associated with quasiparticle excitations, which are Majorana fermions, i.e. particles that are their own antiparticles, obeying non-Abelian statistics and therefore being of prime interest for topological quantum computing. A well-known example are chiral superconductors with px±ipy-wave pairing of electrons into a condensate of Cooper pairs, the carriers of superconductivity. Researchers suggest to consider mesoscopic samples, confined to the energetically favorable domain size, as a suitable platform to verify and potentially control the chiral domains.
