Comments on Noncommutative Gauge Theories
Dongsu Bak, Kimyeong Lee, Jeong-Hyuck Park
We study the gauge theories on noncommutative space. We employ the idea of the covariant position to understand the linear and angular momenta, the center of mass position, and to…
Exact Solutions of Multi-Vortices and False Vacuum Bubbles in Noncommutative Abelian-Higgs Theories
Dongsu Bak
We consider the noncommutative Abelian-Higgs theory and construct new types of exact multi-vortex solutions that solve the static equations of motion. They in general do not follow…
Elongation of Moving Noncommutative Solitons
Dongsu Bak, Kimyeong Lee
We discuss the characteristic properties of noncommutative solitons moving with constant velocity. As noncommutativity breaks the Lorentz symmetry, the shape of moving solitons is…
Noncommutative Field Theories and Smooth Commutative Limits
Dongsu Bak, Sung Ku Kim, Kwang-Sup Soh +1
We consider two model field theories on a noncommutative plane that have smooth commutative limits. One is the single-component fermion theory with quartic interaction that vanishe…
Exact Wavefunctions in a Noncommutative Field Theory
Dongsu Bak, Sung Ku Kim, Kwang-Sup Soh +1
We consider the nonrelativistic field theory with a quartic interaction on a noncommutative plane. We compute the four point scattering amplitude within perturbative analysis to al…
