Build-up of coherence between initially-independent subsystems: The case of Bose-Einstein condensates
O. E. Alon, A. I. Streltsov, L. S. Cederbaum
When initially-independent subsystems are made to contact, {\it coherence} can develop due to interaction between them. We exemplify and demonstrate this paradigm through several s…
Formation and dynamics of many-boson fragmented states in attractive one-dimensional ultra-cold gases
Alexej I. Streltsov, Ofir E. Alon, Lorenz S. Cederbaum
Dynamics of attractive ultra-cold bosonic clouds in one dimension are studied by solving the many-particle time-dependent Schrödinger equation. The initially coherent wave-packet c…
Quantum dynamics in macrosystems with several coupled electronic states: hierarchy of effective Hamiltonians
Etienne Gindensperger, Lorenz S. Cederbaum
We address the nonadiabatic quantum dynamics of macrosystems with several coupled electronic states, taking into account the possibility of multi-state conical intersections. The g…
On-top fragmentation stabilizes atom-rich attractive Bose-Einstein condensates
Lorenz S. Cederbaum, Alexej I. Streltsov, Ofir E. Alon
It is well known that attractive condensates do not posses a stable ground state in three dimensions. The widely used Gross-Pitaevskii theory predicts the existence of metastable s…
High activity of He droplets following ionization of systems inside those droplets
Nikolai V. Kryzhevoi, Vitali Averbukh, Lorenz S. Cederbaum
Relaxation processes following inner-valence ionization of a system can be modified dramatically by embedding this system in a suitable environment. Surprisingly, such an environme…
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…
