Scarring by homoclinic and heteroclinic orbits
D. A. Wisniacki, E. Vergini, R. M. Benito +1
In addition to the well known scarring effect of periodic orbits, we show here that homoclinic and heteroclinic orbits, which are cornerstones in the theory of classical chaos, als…
Signatures of homoclinic motion in quantum chaos
D. A. Wisniacki, E. Vergini, R. M. Benito +1
Homoclinic motion plays a key role in the organization of classical chaos in Hamiltonian systems. In this Letter, we show that it also imprints a clear signature in the correspondi…
Classical invariants and the quantization of chaotic systems
D. A. Wisniacki, E. Vergini, R. M. Benito +1
Long periodic orbits constitute a serious drawback in Gutzwiller's theory of chaotic systems, and then it would be desirable that other classical invariants, not suffering from the…
Different Time Scales in Wave Function Intensity Statistics
D. A. Wisniacki, F. Borondo, E. Vergini +1
Unstable periodic orbits scar wave functions in chaotic systems. This also influences the associated spectra, that follow the otherwise universal Porter--Thomas intensity distribut…
The semiclassical limit of chaotic eigenfunctions
Eduardo G. Vergini
A generic chaotic eigenfunction has a non-universal contribution consisting of scars of short periodic orbits. This contribution, which can not be explained in terms of random univ…
