Inhomogeneous Condensates in Planar QED
Gerald Dunne, Theodore Hall
Abstract
We study the formation of vacuum condensates in 2+1 dimensional QED in the presence of inhomogeneous background magnetic fields. For a large class of magnetic fields, the condensate is shown to be proportional to the inhomogeneous magnetic field, in the large flux limit. This may be viewed as a local form of the integrated degeneracy-flux relation of Aharonov and Casher.
