 Quantum Vortices and Competing Orders

Abstract:  I discuss the theory of two-dimensional superfluids in the vicinity of a quantum transition to a Mott insulator at fractional filling. Vortices in the superfluid, with flux h/(2e), are argued to appear in multiple flavors. These flavors of vortices can interfere with each other as they execute their quantum zero point motion. This interference is proposed as an explanation of recent scanning tunneling microscopy experiments on the cuprate superconductors.
