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…
An alternative approach to Jaynes-Cummings model with dissipation at finite temperature
Le-man Kuang, Guang-hong Chen, Mo-lin Ge +1
An alternative approach to the Jaynes-Cummings model (JCM) with dissipation at a finite enviromental temperature is presented in terms of a new master equation under Born-Markovian…
Applications of Quantum Group to FQH Effect
Guang-Hong Chen, Mo-lin Ge
We show that there exists quantum group symmetry in the fractional quantum Hall effect (FQHE) and this symmetry governs the degeneracy of ground-state level. Under th…
