Realization of balanced gain and loss in a time-dependent four-mode Bose-Hubbard model
Daniel Dizdarevic, Jörg Main, Kirill Alpin +4
A quantum system exhibiting symmetry is a Bose-Einstein condensate in a double-well potential with balanced particle gain and loss, which is described in the mean-fi…

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…

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…
