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…
