Nonlinear optical properties of electromagnetically-induced-transparency medium interacting with two quantized fields
Le-Man Kuang, Guang-Hong Chen, Yong-Shi Wu
We study linear and nonlinear optical properties of electromagnetically induced transparency (EIT) medium interacting with two quantized laser fields for adiabatic EIT case. We sho…
Bosonization and phase Diagram of the one-dimensional t-J model
Guang-Hong Chen, Yong-Shi Wu
We present an analytic study of the phase diagram of the one-dimensional t-J model and a couple of its cousins. To deal with the interactions induced by the no double occupancy con…
Quantum phase transition in a multi-component Bose-Einstein condensate in optical lattices
Guang-Hong Chen, Yong-Shi Wu
We present the general lattice model for a multi-component atomic Bose-Einstein system in the optical lattice. Using the model, we analytically study the quantum phase transition b…
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…
