Three strongly correlated charged bosons in a one-dimensional harmonic trap: natural orbital occupancies
Przemyslaw Koscik
We study a one-dimensional system composed of three charged bosons confined in an external harmonic potential. More precisely, we investigate the ground-state correlation propertie…

Ground-state correlation properties of charged bosons trapped in strongly anisotropic harmonic potentials
Przemyslaw Koscik, Anna Okopinska
We study systems of a few charged bosons contained within a strongly anisotropic harmonic trap. A detailed examination of the ground-state correlation properties of two-, three-, a…

Two-boson Correlations in Various One-dimensional Traps
Anna Okopinska, Przemyslaw Koscik
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…
