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…
The multi-configurational time-dependent Hartree method for bosons: Many-body dynamics of bosonic systems
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
The evolution of Bose-Einstein condensates is amply described by the time-dependent Gross-Pitaevskii mean-field theory which assumes all bosons to reside in a single time-dependent…
Interferences in the density of two Bose-Einstein condensates consisting of identical or different atoms
L. S. Cederbaum, A. I. Streltsov, Y. B. Band +1
The density of two {\it initially independent} condensates which are allowed to expand and overlap can show interferences as a function of time due to interparticle interaction. Tw…
Role of excited states in the splitting dynamics of interacting Bose-Einstein condensates when ramping-up a barrier
Alexej I. Streltsov, Ofir E. Alon, Lorenz S. Cederbaum
An essentially-exact approach to compute the wavefunction in the time-dependent many-boson Schrödinger equation is derived and employed to study accurately the process of splitting…
Cold atoms in real-space optical lattices
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Cold atoms in optical lattices are described in {\it real space} by multi-orbital mean-field Ansätze. In this work we consider four typical systems: (i) spinless identical bosons,…
