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…
Giant non-linearities accompanying electromagnetically induced transparency
Le-Man Kuang, Guang-Hong Chen, Yong-Shi Wu
We develop a fully quantum treatment of electromagnetically induced transparency (EIT) in a vapor of three-level -type atoms. Both the probe and coupling lasers with arbitrary i…
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…
