Berry phase in a non-isolated system
Robert S. Whitney, Yuval Gefen
We investigate the effect of the environment on a Berry phase measurement involving a spin-half. We model the spin+environment using a biased spin-boson Hamiltonian with a time-dep…

Form factor for a family of quantum graphs: An expansion to third order
Gregory Berkolaiko, Holger Schanz, Robert S. Whitney
For certain types of quantum graphs we show that the random-matrix form factor can be recovered to at least third order in the scaled time from periodic-orbit theory. We consid…
