Signature of Quantum Chaos in SQUID's
arXiv:cond-mat/0309224
Abstract
Spectral statistics in band structures is studied in a realistic model describing superconducting quantum interference devices (SQUID's). By controlling an external magnetic flux, the level statistics may show a crossover from the GUE to the GOE. Effects of secondary discrete symmetries seen in specific regions of the first Brillouin zone are also discussed.
