How do wave packets spread? Time evolution on Ehrenfest time scales
Roman Schubert, Raul O. Vallejos, Fabricio Toscano
We derive an extension of the standard time dependent WKB theory which can be applied to propagate coherent states and other strongly localised states for long times. It allows in…

Complexified coherent states and quantum evolution with non-Hermitian Hamiltonians
Eva-Maria Graefe, Roman Schubert
The complex geometry underlying the Schrödinger dynamics of coherent states for non-Hermitian Hamiltonians is investigated. In particular two seemingly contradictory approaches are…
