Anyonic Bogomol'nyi Solitons in a Gauged O(3) Sigma Model
Kyoungtae Kimm, Kimyeong Lee, Taejin Lee
We introduce the self-dual abelian gauged sigma models where the Maxwell and Chern-Simons terms constitute the kinetic terms for the gauge field. These models have quite ric…
Quantum Nucleation of Vortex String Loops
H. C. Kao, K. Lee
We investigate quantum nucleation of vortex string loops in the relativistic quantum field theory of a complex scalar field by using the Euclidean path integral. Our initial metast…
The Chern-Simons Coefficient in the Higgs Phase
H. -C. Kao, K. Lee, C. Lee +1
We study one-loop corrections to the Chern-Simons coefficient in abelian self-dual Chern-Simons Higgs systems and their and supersymmetric generalizations in both s…
Self-DUal SU(3) Chern-Simons Higgs Systems
Hsien-Chung Kao, Kimyeong Lee
We explore self-dual Chern-Simons Higgs systems with the local and global symmetries where the matter field lies in the adjoint representation. We show that there ar…
Quantum tunnelings with global charge
Kimyeong Lee
We investigate quantum tunneling in the theory of a complex scalar field with a global symmetry when the charge density of the initial configuration does not vanish. We disc…
Self-Dual Chern-Simons Higgs Systems with an N=3 Extended Supersymmetry
Hsien-Chung Kao, Kimyeong Lee
We construct and study an N=3 supersymmetric Chern-Simons Higgs theory. This theory is the maximally supersymmetric one containing the self-dual models with a single gauge field an…
