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…
Tracing ultrafast interatomic electronic decay processes in real time and space
Alexander I. Kuleff, Lorenz S. Cederbaum
Tremendous advances in laser pump-probe techniques open the door for the observation in real time of ultrafast \textit{electronic} processes. Particularly attractive is the visuali…
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,…
Time-dependent multi-orbital mean-field for fragmented Bose-Einstein condensates
O. E. Alon, A. I. Streltsov, L. S. Cederbaum
The evolution of Bose-Einstein condensates is usually described by the famous time-dependent Gross-Pitaevskii equation, which assumes all bosons to reside in a single time-dependen…
Interferences in the density of two initially independent Bose-Einstein condensates
L. S. Cederbaum, A. I. Streltsov, Y. B. Band +1
It is shown that 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 interparticl…
Phase separations of bosonic mixtures in optical lattices from macroscopic to microscopic scales
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
Mixtures of cold bosonic atoms in optical lattices undergo phase separations on different length scales with increasing inter-species repulsion. As a general rule, the stronger the…
