Macroscopic quantum tunneling of Bose-Einstein condensates with long-range interaction
Kai Marquardt, Pascal Wieland, Rolf Häfner +3
The ground state of Bose-Einstein condensates with attractive particle interaction is metastable. One of the decay mechanisms of the condensate is a collapse by macroscopic quantum…
Collisions of anisotropic two-dimensional bright solitons in dipolar Bose-Einstein condensates
Rüdiger Eichler, Damir Zajec, Patrick Köberle +2
We investigate the coherent collision of anisotropic quasi-two-dimensional bright solitons in dipolar Bose-Einstein condensates. Our analysis is based on the extended Gross-Pitaevs…
Quantum-classical lifetimes of Rydberg molecules
Andrej Junginger, Jörg Main, Günter Wunner
A remarkable property of Rydberg atoms is the possibility to create molecules formed by one highly excited atom and another atom in the ground state. The first realisation of such…
Symmetry-breaking thermally induced collapse of dipolar Bose-Einstein condensates
Andrej Junginger, Jörg Main, Günter Wunner +1
We investigate a Bose-Einstein condensate with additional long-range dipolar interaction in a cylindrically symmetric trap within a variational framework. Compared to the ground st…
Nonlinear Schrödinger equation for a PT symmetric delta-functions double well
Holger Cartarius, Daniel Haag, Dennis Dast +1
The time-independent nonlinear Schrödinger equation is solved for two attractive delta-function shaped potential wells where an imaginary loss term is added in one well, and a gain…
