Billiard Systems in Three Dimensions: The Boundary Integral Equation and the Trace Formula
Martin Sieber
We derive semiclassical contributions of periodic orbits from a boundary integral equation for three-dimensional billiard systems. We use an iterative method that keeps track of th…
Uniform Approximation for Period-Quadrupling Bifurcations
Martin Sieber, Henning Schomerus
We derive a uniform approximation for semiclassical contributions of periodic orbits to the spectral density which is valid for generic period-quadrupling bifurcations in systems w…
Semiclassical Interpretation of the Mass Asymmetry in Nuclear Fission
M. Brack, S. M. Reimann, M. Sieber
We give a semiclassical interpretation of the mass asymmetry in the fission of heavy nuclei. Using only a few classical periodic orbits and a cavity model for the nuclear mean fiel…
Bifurcations of Periodic Orbits and Uniform Approximations
Henning Schomerus, Martin Sieber
We derive uniform approximations for contributions to Gutzwiller's periodic-orbit sum for the spectral density which are valid close to bifurcations of periodic orbits in systems w…
