Exact Solution Versus Gaussian Approximation for a Non-Ideal Bose Gas in One-Dimension
P. R. I. Tommasini, P. L. Natti, E. R. Takano Natti +2
We investigate ground-state and excitation spectrum of a system of non-relativistic bosons in one-dimension interacting through repulsive, two-body contact interactions in a self-c…
