Action on the Sphere: An Interfering Mean-Field Propagator for the Bose-Hubbard Dimer
Elana F Todd-Miller, Eva-Maria Graefe
The Bose-Hubbard system has been studied extensively both theoretically and experimentally, in particular in the context of ultracold atomic gases in optical lattices. Even in the…

Phase-space measurements and decoherence for angular momentum systems
Dorje C. Brody, Eva-Maria Graefe, Rishindra Melanathuru
The monitoring of the three independent components of the angular momentum (or spin) of a quantum system by its environment that does not isolate any preferred orientation is model…

Intensity landscapes in elliptical and oval billiards with a circular absorbing region
Katherine Holmes, Joseph Hall, Eva-Maria Graefe
Billiard models of single particles moving freely in two-dimensional regions enclosed by hard walls, have long provided ideal toy models for the investigation of dynamical systems…
