BPS Center Vortices in Nonrelativistic SU(N) Gauge Models with Adjoint Higgs Fields

BPS Center Vortices in Nonrelativistic SU(N) Gauge Models with Adjoint Higgs Fields

We propose a class of SU(N) Yang-Mills models, with adjoint Higgs fields, that accept BPS center vortex equations. The lack of a local magnetic flux that could serve as an energy bound is circumvented by including a new term in the energy functional. This term tends to align, in the Lie algebra, the...
