Pairing of particle-hole symmetric composite fermions in half-filled Landau level
Pairing of particle-hole symmetric composite fermions in half-filled Landau level
In a recent proposal of the half-filled Landau level, the composite fermions are taken to be Dirac particles and particle-hole symmetric. Cooper pairing of these composite fermions in different angular momentum channels, $\ensuremath{\ell}$, can give rise to different kinds of Pfaffian states. In addition to the well-known Moore-Read Pfaffian and …
