Mean-field dynamics of a non-Hermitian Bose-Hubbard dimer
E. M. Graefe, H. J. Korsch, A. E. Niederle
We investigate an -particle Bose-Hubbard dimer with an additional effective decay term in one of the sites. A mean-field approximation for this non-Hermitian many-particle syste…

A non-Hermitian symmetric Bose-Hubbard model: eigenvalue rings from unfolding higher-order exceptional points
E. M. Graefe, U. Guenther, H. J. Korsch +1
We study a non-Hermitian symmetric generalization of an -particle, two-mode Bose-Hubbard system, modeling for example a Bose-Einstein condensate in a double well potential…

Mean-field dynamics of a Bose-Einstein condensate in a time-dependent triple-well trap: Nonlinear eigenstates, Landau-Zener models and STIRAP
E. M. Graefe, H. J. Korsch, D. Witthaut
We investigate the dynamics of a Bose--Einstein condensate (BEC) in a triple-well trap in a three-level approximation. The inter-atomic interactions are taken into account in a mea…
