Title Flux Phase of the Half-Filled Band
Speaker Dr. Vikram Tripathi
Date Wed, 18 Aug 2010
Time 14:30
Venue A 304


The conjecture is verified that the optimum, energy minimizing, magnetic flux for a half-filled band of electrons hopping on a planar, bipartite graph is π per square plaquette. We require only that the graph has periodicity in one direction and the result includes the hexagonal lattice (with flux 0 per hexagon) as a special case.
