Reduced density matrices and coherence of trapped interacting bosons
Kaspar Sakmann, Alexej I. Streltsov, Ofir E. Alon +1
The first- and second-order correlation functions of trapped, interacting Bose-Einstein condensates are investigated numerically on a many-body level from first principles. Correla…
Exact ground state of finite Bose-Einstein condensates on a ring
Kaspar Sakmann, Alexej I. Streltsov, Ofir E. Alon +1
The exact ground state of the many-body Schrödinger equation for bosons on a one-dimensional ring interacting via pairwise -function interaction is presented for up to fifty…
Continuous configuration-interaction for condensates in a ring
Ofir E. Alon, Alexej I. Streltsov, Kaspar Sakmann +1
A continuous configuration-interaction approach for condensates in a ring is introduced. In its simplest form this approach utilizes for attractive condensates the Gross-Pitaevskii…
