Title:
Particle-hole symmetry and the nature of the composite fermion
Speaker:
Abstract:
I will describe the new picture of the half-filled Landau level, according to which the composite fermion is a massless Dirac fermion in the limit of vanishing Landau-level mixing. Such a fermion is characterized by a Berry phase of pi around the Fermi disk. Physical consequences of the new picture are outlined.
