Andreev reflection of fractional quantum Hall quasiparticles

Andreev reflection of fractional quantum Hall quasiparticles

Andreev reflection is normally known to occur at a metal-superconductor interface. Here, Hashisaka et al. observe an Andreev-like process in a narrow junction between fractional and integer quantum Hall states originating from a topological quantum many-body effect instead of superconductivity.
