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…
-symmetric wave guide system with evidence of a third-order exceptional point
Jan Schnabel, Holger Cartarius, Jörg Main +2
An experimental setup of three coupled -symmetric wave guides showing the characteristics of a third-order exceptional point (EP3) has been investigated in an idealiz…
Vortices in Bose-Einstein condensates with -symmetric gain and loss
Lukas Schwarz, Holger Cartarius, Ziad H. Musslimani +2
We investigate vortex excitations in dilute Bose-Einstein condensates in the presence of complex -symmetric potentials. These complex potentials are used to describe…
Relation between -symmetry breaking and topologically nontrivial phases in the SSH and Kitaev models
Marcel Klett, Holger Cartarius, Dennis Dast +2
Non-Hermitian systems with symmetry can possess purely real eigenvalue spectra. In this work two one-dimensional systems with two different topological phases, the t…
