Potential harmonics expansion method for trapped interacting bosons: Inclusion of two-body correlation
Potential harmonics expansion method for trapped interacting bosons: Inclusion of two-body correlation
We study a system of $A$ identical interacting bosons trapped by an external field by solving ab initio the many-body Schroedinger equation. A complete solution by using, for example, the traditional hyperspherical harmonics (HH) basis develops serious problems due to the large degeneracy of HH basis, symmetrization of the wave …
