Monopole-antimonopole chains and closed vorticesin Yang-Mills-Higgs and Einstein-Yang-Mills-Higgs theory
Séminaire informel
We discuss properties of the axially symmetric static saddle point solutions of SU(2) Yang-Mills-Higgs theory which represent composite states of monopoles and antimonopoles and/or vortex rings. They are either deformations of the topologically trivial sector or deformations of the axially symmetric charge n multimonopole. The energy of these configurations exceeds the Bogomol’nyi bound even in the limit of vanishing scalar coupling. When the theory is coupled with gravity new branches of the graviting monopoles/vortices emerges smoothly from these flat space configurations. We discuss interpretation of the upper branche configuration as a composite system consisting of Bartnik-McKinnon solution of EYM theory and an outer multimonopole/vortex solution of the EYMH theory.
