Controlling Quantum Chaos: Optimal Coherent Targeting
Steven Tomsovic, Juan Diego Urbina, Klaus Richter
One of the principal goals of controlling classical chaotic dynamical systems is known as targeting, which is the very weakly perturbative process of using the system's extreme sen…
Efficient semiclassical approach for time delays
Jack Kuipers, Dmitry V. Savin, Martin Sieber
The Wigner time delay, defined by the energy derivative of the total scattering phase shift, is an important spectral measure of an open quantum system characterising the duration…
Fidelity decay for local perturbations: microwave evidence for oscillating decay exponents
Bernd Köber, Ulrich Kuhl, Hans-Jürgen Stöckmann +2
We study fidelity decay in classically chaotic microwave billiards for a local, piston-like boundary perturbation. We experimentally verify a predicted non-monotonic cross-over fro…
Normal forms and uniform approximations for bridge orbit bifurcations
Ken-ichiro Arita, Matthias Brack
We discuss various bifurcation problems in which two isolated periodic orbits exchange periodic ``bridge'' orbit(s) between two successive bifurcations. We propose normal forms whi…
Analytic approach to bifurcation cascades in a class of generalized Hénon-Heiles potentials
S. N. Fedotkin, A. G. Magner, M. Brack
We derive stability traces of bifurcating orbits in Hénon-Heiles potentials near their saddles
Random Wave Functions with boundary and normalization constraints: Quantum statistical physics meets quantum chaos
Juan Diego Urbina, Klaus Richter
We present an improved version of Berry's ansatz able to incorporate exactly the existence of boundaries and the correct normalization of the eigenfunction into an ensemble of rand…
