Effective-potential classification of kink-antikink collision channels in the scalar field theory
Yun Feng, Yunguo Jiang
We study kink-antikink collisions in a -dimensional scalar field theory with multiple degenerate vacua. We derive soliton solutions for different vacuum structures lab…
Toda chain from the kink-antikink lattice
Song He, Yunguo Jiang, Jiazhen Liu
In this paper, we have studied the kink and antikink solutions in several neutral scalar models in 1+1 dimension. We follow the standard approach to write down the leading order an…
Mass deformed world-sheet action of semi-local vortices
Yunguo Jiang
The mass deformed effective world-sheet theory of semi local vortices was constructed via the field theoretical method. By Euler-Lagrangian equations, the Ansatze for both the gaug…
Anomalous spin of the Chern-Simons-Georgi-Glashow model
Huo Qiu-Hong, Jiang Yunguo
With the Coulomb gauge, the Chern-Simons-Georgi-Glashow (CSGG) model is quantized in the Dirac formalism for the constrained system. Combining the Gauss law and Coulomb gauge consi…
Vortices and Monopoles in Mass-deformed SO and USp Gauge Theories
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +4
Effects of mass deformations on 1/2 Bogomol'nyi-Prasad-Sommerfield (BPS) non-Abelian vortices are studied in 4d N=2 supersymmetric U(1) \times SO(2n) and U(1) \times USp(2n) gauge…
Group Theory of Non-Abelian Vortices
Minoru Eto, Toshiaki Fujimori, Sven Bjarke Gudnason +4
We investigate the structure of the moduli space of multiple BPS non-Abelian vortices in U(N) gauge theory with N fundamental Higgs fields, focusing our attention on the action of…
Non-Abelian vortex dynamics: Effective world-sheet action
Sven Bjarke Gudnason, Yunguo Jiang, Kenichi Konishi
The low-energy vortex effective action is constructed in a wide class of systems in a color-flavor locked vacuum, which generalizes the results found earlier in the context of U(N)…
Faddeev-Senjanovic Quantization of Supersymmetrical Electrodynamical System
Yun-Guo Jiang, Yong-Chang Huang
According to the method of path integral quantization for the canonical constrained system in Faddeev-Senjanovic scheme, we quantize the supersymmetrical electrodynamic system in g…
