Nonabelian Vortices on Surfaces and Their Statistics
Lee Brekke, Sterrett J. Collins, Tom D. Imbo
We discuss the physics of topological vortices moving on an arbitrary surface M in a Yang-Mills-Higgs theory in which the gauge group G breaks to a finite subgroup H. We concentrat…
Spinning Particles, Braid Groups and Solitons
Lee Brekke, Michael J. Dugan, Tom D. Imbo
We develop general techniques for computing the fundamental group of the configuration space of identical particles, possessing a generic internal structure, moving on a manifo…
Rings and Balls
Lee Brekke, Shane J. Hughes, Tom D. Imbo
We examine the various linkings in space-time of ``ball-like'' and ``ring-like'' topological solitons in certain nonlinear sigma models in 2+1 and 3+1 dimensions. By going to theor…
Novel Spin and Statistical Properties of Nonabelian Vortices
Lee Brekke, Hans Dykstra, Adam F. Falk +1
We study the statistics of vortices which appear in (2+1)--dimensional spontaneously broken gauge theories, where a compact group G breaks to a finite nonabelian subgroup H. Two si…
