Laplacian Center Vortices

摘要

I present a unified picture of center vortices and Abelian monopoles. Bothappear as local gauge ambiguities in the Laplacian Center Gauge. This gauge isconstructed for a general SU(N) theory. Numerical evidence is presented, forSU(2) and SU(3), that the projected $Z_N$ theory confines with a string tensionsimilar to the non-Abelian one.
