摘要
Generalizing the notion of composite fermions to the case of '' pseudorelativistic '' quantum Hall phenomena in graphene, we discuss a possible emergence of compressible states at the filling factors nu=+/- 1/2,+/- 3/2. This analysis is further extended to the nearby incompressible states viewed as integer quantum Hall effect of composite Dirac fermions, as well as those at nu=0,+/- 1 that occur as a result of (pseudo)spin-singlet pairing between the latter.
