Nonlinear quantum dynamics in a PT-symmetric double well
Daniel Haag, Dennis Dast, Andreas Löhle +3
We investigate the mean-field dynamics of a Bose-Einstein condensate (BEC) described by the Gross-Pitaevskii equation (GPE) in a double-well potential with particle gain and loss,…
Dipolar Bose-Einstein condensates in triple-well potentials
Rüdiger Fortanier, Damir Zajec, Jörg Main +1
Dipolar Bose-Einstein condensates in triple-well potentials are well-suited model systems for periodic optical potentials with important contributions of the non-local and anisotro…
Transition states and thermal collapse of dipolar Bose-Einstein condensates
Andrej Junginger, Manuel Kreibich, Jörg Main +1
We investigate thermally excited, dipolar Bose-Einstein condensates. Quasi-particle excitations of the atomic cloud cause density fluctuations which can induce the collapse of the…
Hermitian four-well potential as a realization of a PT-symmetric system
Manuel Kreibich, Jörg Main, Holger Cartarius +1
A PT-symmetric Bose-Einstein condensate can be theoretically described using a complex optical potential, however, the experimental realization of such an optical potential describ…
Spectral singularities in PT-symmetric Bose-Einstein condensates
W. D. Heiss, H. Cartarius, G. Wunner +1
We consider the model of a PT-symmetric Bose-Einstein condensate in a delta-functions double-well potential. We demonstrate that analytic continuation of the primarily non-analytic…
