Description:
Author(s): Ram Band and Gregory Berkolaiko The momentum spectrum of a periodic network (quantum graph) has a band-gap structure. We investigate the relative density of the bands or, equivalently, the probability that a randomly chosen momentum belongs to the spectrum of the periodic network. We show that this probability exhibits universal p... [Phys. Rev. Lett. 111, 130404] Published Tue Sep 24, 2013
