Laplacian Center Vortices

摘要

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