Near action-degenerate periodic-orbit bunches: A skeleton of chaos
Alexander Altland, Petr Braun, Fritz Haake +3
Long periodic orbits of hyperbolic dynamics do not exist as independent individuals but rather come in closely packed bunches. Under weak resolution a bunch looks like a single orb…

Periodic-orbit theory of universal level correlations in quantum chaos
Sebastian Müller, Stefan Heusler, Alexander Altland +2
Using Gutzwiller's semiclassical periodic-orbit theory we demonstrate universal behaviour of the two-point correlator of the density of levels for quantum systems whose classical l…
