Events in Physics

In this talk, I shall discuss the properties of interacting electrons in monolayer graphene in a strong magnetic field. I shall demonstrate how the effect of the Coulomb interaction differs in a crucial way from that in a conventional two-dimensional electron system [PRL 97, 126801 (2006)]. I will also discuss briefly the experimental work reported on the fractional QHE in graphene. In the second half of the talk, I plan to discuss the physics of bilayer graphene in a strong magnetic field. I will explain how the physics of FQHE in this system differs dramatically from that in monolayer graphene and offers unique possibilities to probe the nature of incompressible/compressible states [PRL 105, 036801 (2010)]. I will also discuss (very briefly) the nature of the Pfaffian state in bilayer graphene [PRL 107, 186803 (2011)].
