Potential Harmonics Expansion Method for Trapped Interacting Bosons : Inclusion of Two-Body Correlation
T. K. Das, B. Chakrabarti
We study a system of identical interacting bosons trapped by an external field by solving ab initio the many-body Schroedinger equation. A complete solution by using, for examp…
