Description

A one-dimensional system of two trapped bosons which interact through a contact potential is studied using the optimized configuration interaction method. The rapid convergence of the method is demonstrated for a series of trapping potentials of convex and non-convex shapes. The energy spectra, as well as natural orbitals and their occupation numbers are determined in function of the interboson interaction strength. Various correlation characteristics are discussed in dependence both on the shape of the confining potential and on the sign and strength of the interaction. Entanglement properties are examined particularly carefully. In all the cases studied, a special attention is paid to the demonstration of the fermionization effects when the interaction becomes strong enough.
