Bifurcations and exceptional points in a PT-symmetric dipolar Bose-Einstein condensate
Robin Gutöhrlein, Holger Cartarius, Jörg Main +1
We investigate the bifurcation structure of stationary states in a dipolar Bose-Einstein condensate located in an external PT-symmetric potential. The imaginary part of this extern…
Realizing PT-symmetric BEC subsystems in closed hermitian systems
Robin Gutöhrlein, Jan Schnabel, Ibrokhim Iskandarov +3
In open double-well Bose-Einstein condensate systems which balance in- and outfluxes of atoms and which are effectively described by a non-hermitian PT-symmetric Hamiltonian PT-sym…
Dipolar Bose-Einstein condensates in a PT-symmetric double-well potential
Rüdiger Fortanier, Dennis Dast, Daniel Haag +4
We investigate dipolar Bose-Einstein condensates in a complex external double-well potential that features a combined parity and time-reversal symmetry. On the basis of the Gross-P…
Bifurcations and exceptional points in dipolar Bose-Einstein condensates
Robin Gutöhrlein, Jörg Main, Holger Cartarius +1
Bose-Einstein condensates are described in a mean-field approach by the nonlinear Gross-Pitaevskii equation and exhibit phenomena of nonlinear dynamics. The eigenstates can undergo…
