New Results on Non-Abelian Vortices — Further Insights into Monopole, Vortex and Confinement

Abstract

We discuss some of the latest results concerning the non-Abelian vortices. The first concerns the construction of non-Abelian BPS vortices based on general gauge groups of the form G = G′×U(1). In particular detailed results about the vortex moduli space have been obtained for G′ = SO(N) or U Sp(2N). The second result is about the fractional vortices, i.e., vortices of the minimum winding but having substructures in the tension (or flux) density in the transverse plane. Thirdly, we discuss briefly the monopole-vortex complex.
