Wave packet evolution in non-Hermitian quantum systems
Eva-Maria Graefe, Roman Schubert
The quantum evolution of the Wigner function for Gaussian wave packets generated by a non-Hermitian Hamiltonian is investigated. In the semiclassical limit this yields…

Quantum Classical Correspondence for a non-Hermitian Bose-Hubbard Dimer
Eva-Maria Graefe, Hans Jürgen Korsch, Astrid Elisa Niederle
We investigate the many-particle and mean-field correspondence for a non-Hermitian N-particle Bose-Hubbard dimer where a complex onsite energy describes an effective decay from one…

Coherent states and rational surfaces
Dorje C. Brody, Eva-Maria Graefe
The state spaces of generalised coherent states associated with special unitary groups are shown to form rational curves and surfaces in the space of pure states. These curves and…
