Does Berry phase exist for a system coupled to its environment?

Robert S. Whitney, Yuval Gefen

Berry phase was originally defined for systems whose states are separated by finite energy gaps. One might naively expect that a system without a gap cannot have a Berry phase. Des…

The Leading Off-Diagonal Correction to the Form Factor of Large Graphs

Gregory Berkolaiko, Holger Schanz, Robert S. Whitney

Using periodic-orbit theory beyond the diagonal approximation we investigate the form factor, $K (τ)$ , of a generic quantum graph with mixing classical dynamics and time-reversal sy…
