PT-symmetric gain and loss in a rotating Bose-Einstein condensate
Daniel Haag, Dennis Dast, Holger Cartarius +1
PT-symmetric quantum mechanics allows finding stationary states in mean-field systems with balanced gain and loss of particles. In this work we apply this method to rotating Bose-E…
Balanced gain and loss in Bose-Einstein condensates without PT symmetry
Philipp Lunt, Daniel Haag, Dennis Dast +2
Balanced gain and loss renders the mean-field description of Bose-Einstein condensates PT symmetric. However, any experimental realization has to deal with unbalancing in the gain…
Stationary states in the many-particle description of Bose-Einstein condensates with balanced gain and loss
Dennis Dast, Daniel Haag, Holger Cartarius +2
Bose-Einstein condensates with balanced gain and loss can support stationary states despite the exchange of particles with the environment. In the mean-field approximation this is…
