“The fractional quantum Hall effect (FQHE) is a topological quantum state of matter that has no small parameter, no spontaneously broken symmetry, and no order parameter. Nonetheless, a remarkably detailed and accurate understanding of its nonperturbative physics has been achieved in terms of a new class of exotic particles called composite fermions. I will begin with a brief review of the composite fermion theory and its successes. The remainder of the talk will focus on several recent developments, which include: pairing of composite fermions and the emergence of majorana composite fermions, FQHE for purely three body interactions, and novel high energy excitons in the FQHE.”
