Generic regimes of quantum many-body dynamics of trapped bosonic systems with strong repulsive interactions
Oksana I. Streltsova, Ofir E. Alon, Lorenz S. Cederbaum +1
Two generically different but universal dynamical quantum many-body behaviors are discovered by probing the stability of trapped fragmented bosonic systems with strong repulsive fi…
Elastic scattering of a Bose-Einstein condensate at a potential landscape
Iva Brezinova, Axel U. J. Lode, Alexej I. Streltsov +5
We investigate the elastic scattering of Bose-Einstein condensates at shallow periodic and disorder potentials. We show that the collective scattering of the macroscopic quantum ob…
Controlling the Velocities and Number of Emitted Particles in the Tunneling to Open Space Dynamics
Axel U. J. Lode, Shachar Klaiman, Ofir. E. Alon +2
A scheme to control the many-boson tunneling process to open space is derived and demonstrated. The number of ejected particles and their velocities can be controlled by two parame…
Unified view on linear response of interacting identical and distinguishable particles from multiconfigurational time-dependent Hartree methods
Ofir E. Alon, Alexej I. Streltsov, Lorenz S. Cederbaum
A unified view on linear response of interacting systems utilizing multicongurational time-dependent Hartree methods is presented. The cases of one-particle and two-particle respon…
Quantum systems of ultra-cold bosons with customized inter-particle interactions
Alexej I. Streltsov
Recent progress in cooling and trapping of polarized clouds of chromium , dysprosium and erbium opens a road-map to quantum systems where shapes of i…
Excitation spectra of many-body systems by linear response: General theory and applications to trapped condensates
Julian Grond, Alexej I. Streltsov, Axel U. J. Lode +3
We derive a general linear-response many-body theory capable of computing excitation spectra of trapped interacting bosonic systems, e.g., depleted and fragmented Bose-Einstein con…
