Quasiclassical analysis of Bloch oscillations in non-Hermitian tight-binding lattices
E M Graefe, H J Korsch, A Rush
Many features of Bloch oscillations in one-dimensional quantum lattices with a static force can be described by quasiclassical considerations for example by means of the accelerati…
Classical-quantum correspondence in bosonic two-mode conversion systems: polynomial algebras and Kummer shapes
Eva-Maria Graefe, Hans Jürgen Korsch, Alexander Rush
Bosonic quantum conversion systems can be modeled by many-particle single-mode Hamiltonians describing a conversion of molecules of type A into molecules of type B and vice…
Semiclassical quantisation for a bosonic atom-molecule conversion system
Eva-Maria Graefe, Maria Graney, Alexander Rush
We consider a simple quantum model of atom-molecule conversion where bosonic atoms can combine into diatomic molecules and vice versa. The many-particle system can be expressed in…
Classical and quantum dynamics in the (non-Hermitian) Swanson oscillator
Eva-Maria Graefe, Hans Jürgen Korsch, Alexander Rush +1
The non-Hermitian quadratic oscillator studied by Swanson is one of the popular -symmetric model systems. Here a full classical description of its dynamics is derived using rec…
