Condensate wave function of neutral Bose atoms in power-law traps
Sang-Hoon Kim, Chang Sub Kim
The macroscopic quantum states of a condensed neutral Bose gas in one-dimensional power-law traps are obtained by solving the Gross-Pitaevskii equation numerically. A suitable cand…
Condensate of charged Bose disks with numerous holes in a uniform magnetic field
Sang-Hoon Kim
A stack of disks with numerous holes composed of a non-interacting charged Bose gas is modeled as a low dimensional disk. The Bose condensation of the net-like disk system in a uni…
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…
Condensate of low dimensional charged Bose disks in a uniform magnetic field
Sang-Hoon Kim, Peter Pfeifer
The Bose condensation of a stack of low dimensional disks which is composed of a noninteracting charged Bose gas in a uniform magnetic field is studied. A statistical approach with…
Two-Dimensional Gross-Pitaevskii Equation: Theory of Bose-Einstein Condensation and the Vortex State
Sang-Hoon Kim, Changyeon Won, Sung Dahm Oh +1
We derive the Gross-Pitaevskii equation in two-dimension from the first principles of two-dimensional scattering theory. Numerical calculation of the condensate wave function shows…
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…
