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…
The Functional Schrödinger Picture Approach to Many-Particle Systems
Chul Koo Kim, Sang Koo You
A self-contained pedagogical introduction to the functional Schrödinger picture method of many-body theory is given at a level suitable for graduate students and also for many-body…
Condensate of a charged boson fluid at non-integer dimensions
Sang-Hoon Kim, Chul Koo Kim, Kyun Nahm
Condensate of a charged boson fluid at non-integer dimensions between 2 and 3 is studied. Interaction between particles is assumed to be Coulombic, and Bogoliubov approximation is…
Phase Diagram of a Two-Dimensional Neutral Classical Coulomb Gas from a Non-perturbative sine-Gordon Expansion
Wen-Fa Lu, Chul Koo Kim
Within the sine-Gordon formalism of a two-dimensional neutral classical Coulomb gas, a convergent expansion with non-perturbative nature is performed to calculate the thermodynamic…
Fluctuation correction to the ground state energy density of a dilute Bose gas in the functional Schrödinger picture
Sang-Hoon Kim, Hyun Sik Noh, Dae Kwan Kim +2
A dilute Bose gas system is studied using the functional Schrödinger picture theory. The ground state properties are obtained by solving the infinite dimensional Schrödinger equati…
