Symmetry and dynamics universality of supermetal in quantum chaos

Symmetry and dynamics universality of supermetal in quantum chaos

Chaotic systems exhibit rich quantum dynamical behaviors ranging from dynamical localization to normal diffusion to ballistic motion. Dynamical localization and normal diffusion simulate electron motion in an impure crystal with a vanishing and finite conductivity, i.e., an "Anderson insulator" and a "metal", respectively. Ballistic motion simulates a perfect crystal with …
