Wannier functions using a discrete variable representation for optical lattices
Saurabh Paul, Eite Tiesinga
We propose a numerical method using the discrete variable representation (DVR) for constructing real-valued Wannier functions localized in a unit cell for both symmetric and asymme…

A Hubbard model for ultracold bosonic atoms interacting via zero-point-energy induced three-body interactions
Saurabh Paul, P. R. Johnson, Eite Tiesinga
We show that for ultra-cold neutral bosonic atoms held in a three-dimensional periodic potential or optical lattice, a Hubbard model with dominant, attractive three-body interactio…
