First-order quantum correction to the ground-state energy density of two-dimensional hard-sphere Bose atoms
Sang-Hoon Kim, Mukunda P. Das
Divergence exponents of the first-order quantum correction of a two-dimensional hard-sphere Bose atoms are obtained by an effective field theory method. The first-order correction…

Stability of the homogeneous Bose-Einstein condensate at large gas parameter
Abdulla Rakhimov, Chul Koo Kim, Sang-Hoon Kim +1
The properties of the uniform Bose gas is studied within the optimized variational perturbation theory (Gaussian approximation) in a self-consistent way. It is shown that the atomi…
