Massive and massless monopoles with nonabelian magnetic charges
Kimyeong Lee, Erick J. Weinberg, Piljin Yi
We use the multimonopole moduli space as a tool for studying the properties of BPS monopoles carrying nonabelian magnetic charges. For configurations whose total magnetic charge is…
SELF-DUAL ANYONS IN UNIFORM BACKGROUND FIELDS
Kimyeong Lee, Piljin Yi
We study relativistic self-dual Chern-Simons-Higgs systems in the presence of uniform background fields that explicitly break CTP. A rich, but discrete vacuum structure is found wh…
Nontopological Magnetic Monopoles and New Magnetically Charged Black Holes
Kimyeong Lee, Erick J. Weinberg
The existence of nonsingular classical magnetic monopole solutions is usually understood in terms of topologically nontrivial Higgs field configurations. We show that finite energy…
The Dual Formulation of Cosmic Strings and Vortices
Kimyeong Lee
We study four dimensional systems of global, axionic and local strings. By using the path integral formalism, we derive the dual formulation of these systems, where Goldstone boson…
Black Holes in Magnetic Monopoles
K. Lee, V. P. Nair, Erick J. Weinberg
We study magnetically charged classical solutions of a spontaneously broken gauge theory interacting with gravity. We show that nonsingular monopole solutions exist only if the Hig…
