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 $τ$ from periodic-orbit theory. We consid…

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…
