Effective-interaction approach to the many-boson problem
J. Christensson, C. Forssén, S. Åberg +1
We show that the convergence behavior of the many-body numerical diagonalization scheme for strongly interacting bosons in a trap can be significantly improved by the Lee-Suzuki me…

Exact diagonalization results for an anharmonically trapped Bose-Einstein condensate
S. Bargi, G. M. Kavoulakis, S. M. Reimann
We consider bosonic atoms that rotate in an anharmonic trapping potential. Using numerical diagonalization of the Hamiltonian, we identify the various phases of the gas as the rota…
