Condensate fragmentation as a sensitive measure of the quantum many-body behavior of bosons with long-range interactions
Uwe R. Fischer, Axel U. J. Lode, Budhaditya Chatterjee
The occupation of more than one single-particle state and hence the emergence of fragmentation is a many-body phenomenon universal to systems of spatially confined interacting boso…
Vortex reconnections in anisotropic trapped three-dimensional Bose-Einstein condensates
T. Wells, A. U. J. Lode, V. S. Bagnato +1
Quantum vortex reconnections can be considered as a fundamental unit of interaction in complex turbulent quantum gases. Understanding the dynamics of single vortex reconnections as…
Breaking the resilience of a two-dimensional Bose-Einstein condensate to fragmentation
Shachar Klaiman, Axel U. J. Lode, Alexej I. Streltsov +2
A two-dimensional Bose-Einstein condensate (BEC) split by a radial potential barrier is investigated. We determine on an accurate many-body level the system's ground-state phase di…
How does an interacting many-body system tunnel through a potential barrier to open space?
Axel U. J. Lode, Alexej I. Streltsov, Kaspar Sakmann +2
The tunneling process in a many-body system is a phenomenon which lies at the very heart of quantum mechanics. It appears in nature in the form of alpha-decay, fusion and fission i…
Mechanism of Tunneling in Interacting Open Ultracold Few-Boson Systems
Axel U. J. Lode, Alexej I. Streltsov, Ofir E. Alon +1
We investigate the mechanism in the tunneling dynamics of open ultracold few-boson systems by numerically solving the time-dependent few-boson Schrödinger equation exactly. By star…
