The scar mechanism revisited
F. Borondo, D. A. Wisniacki, E. G. Vergini +1
Unstable periodic orbits are known to originate scars on some eigenfunctions of classically chaotic systems through recurrences causing that some part of an initial distribution of…
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…
Scar functions in the Bunimovich Stadium billiard
Gabriel Carlo, Eduardo Vergini, Pablo Lustemberg
In the context of the semiclassical theory of short periodic orbits, scar functions play a crucial role. These wavefunctions live in the neighbourhood of the trajectories, resembli…
Sensitivity to perturbations in a quantum chaotic billiard
Diego A. Wisniacki, Eduardo Vergini, Horacio M. Pastawski +1
The Loschmidt echo (LE) measures the ability of a system to return to the initial state after a forward quantum evolution followed by a backward perturbed one. It has been conjectu…
Localization properties of groups of eigenstates in chaotic systems
D. A. Wisniacki, F. Borondo, E. Vergini +1
In this paper we study in detail the localized wave functions defined in Phys. Rev. Lett. {\bf 76}, 1613 (1994), in connection with the scarring effect of unstable periodic orbits…
Classical invariants and the quantum-classical link
Diego. A. Wisniacki, Eduardo Vergini
The classical invariants of a Hamiltonian system are expected to be derivable from the respective quantum spectrum. In fact, semiclassical expressions relate periodic orbits with e…
Beyond the First Recurrence in Scar Phenomena
D. A. Wisniacki, F. Borondo, E. Vergini +1
The scarring effect of short unstable periodic orbits up to times of the order of the first recurrence is well understood. Much less is known, however, about what happens past this…
