Electromagnetically induced transparency in an atom-molecule Bose-Einstein condensate
Guang-Ri Jin, Chul Koo Kim, Kyun Nahm
We propose a new measurement scheme for the atom-molecule dark state by using electromagnetically induced transparency (EIT) technique. Based on a density-matrix formalism, we calc…
Quantum Dynamics and Statistics Properties of Atom-Molecule Bose-Einstein Condensate
Guang-Ri Jin, Chul Koo Kim, Kyun Nahm
Based on a two-mode boson model, we study nonclassical properties of the atom-molecule Bose-Einstein condensate. The effects of nonlinear collisions on the dynamics of the molecula…
Modulational instability of two-component Bose-Einstein condensates in an optical lattice
Guang-Ri Jin, Chul Koo Kim, Kyun Nahm
We study modulational instability of two-component Bose-Einstein condensates in an optical lattice, which is modelled as a coupled discrete nonlinear Schr ödinger equation. The exc…
Fano resonance in electron transport through parallel double quantum dots in the Kondo regime
Guo-Hui Ding, C. K. Kim, K. Nahm
Electron transport through parallel double quantum dot system with interdot tunneling and strong on-site Coulomb interaction is studied in the Kondo regime by using the finite-…
Diamagnetic response of Aharonov-Bohm rings: Impurity backward scatterings
Mun Dae Kim, Chul Koo Kim, Kyun Nahm
We report a theoretical calculation on the persistent currents of disordered normal-metal rings. It is shown that the diamagnetic responses of the rings in the vicinity of the zero…
Sine-Gordon Effective Potential beyond Gaussian Approximation
Wen-Fa Lu, Chul Koo Kim, Kyun Nahm
Combining an optimized expansion scheme in the spirit of the background field method with the Coleman's normal-ordering renormalization prescription, we calculate the effective pot…
