On Gauge Invariance of Noncommutative Chern-Simons Theories
Guang-Hong Chen, Yong-Shi Wu
Motivated by possible applications to condensed matter systems, in this paper we construct U(N) noncommutative Chern-Simons (NCCS) action for a disc and for a double-layer geometry…
Renormalization Group Equations and the Lifshitz Point In Noncommutative Landau-Ginsburg Theory
Guang-Hong Chen, Yong-Shi Wu
A one-loop renormalization group (RG) analysis is performed for noncommutative Landau-Ginsburg theory in an arbitrary dimension. We adopt a modern version of the Wilsonian RG appro…
On Critical Phenomena in a Noncommutative Space
Guang-Hong Chen, Yong-Shi Wu
In this paper we demonstrate that coordinate noncommutativity at short distances can show up in critical phenomena through UV-IR mixing. In the symmetric phase of the Landau-Ginsbu…
One-loop Shift in Noncommutative Chern-Simons Coupling
Guang-Hong Chen, Yong-Shi Wu
In this paper we study the one-loop shift in the coupling constant in a noncommutative pure U(N) Chern-Simons gauge theory in three dimensions. The one-loop shift is shown to be a…
Comments on Noncommutative Open String Theory: V-duality and Holography
Guang-Hong Chen, Yong-Shi Wu
In this paper we study the interplay of electric and magnetic backgrounds in determining the decoupling limit of coincident D-branes towards a noncommutative Yang-Mills (NCYM) or o…
