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…

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…
