Semiclassical matrix elements for a chaotic propagator in the scar function basis
(IOP Publishing, 2013-03)
A semiclassical approximation for the matrix elements of a quantum chaotic propagator in the scar function basis has been derived. The obtained expression is solely expressed in terms of canonical invariant objects. For ...
Time-reversal focusing and space-time control of interferences :
(2010-03)
La focalización de ondas acústicas que se propagan por un medio inhomogéneo fue lograda con éxito a través del procedimiento conocido como espejo de reversión temporal (TRM). En este experimento, las ondas salientes son ...

Perturbations and chaos in quantum maps
(American Physical Society, 2012-08)
The local density of states (LDOS) is a distribution that characterizes the effects of perturbations on quantum systems. Recently, a semiclassical theory was proposed for the LDOS of chaotic billiards and maps. This theory ...
Dynamical thermalization of Bose-Einstein condensate in Bunimovich stadium
(IOP Publishing, 2015-09)
We study numerically the wave function evolution of a Bose-Einstein condensate in a Bunimovich stadium billiard being governed by the Gross-Pitaevskii equation. We show that for a moderate nonlinearity, above a certain ...
Universal wave functions structure in mixed systems
(IOP Publishing, 2014-06)
When a regular classical system is perturbed, nonlinear resonances appear as prescribed by the KAM and Poincar`e-Birkhoff theorems. Manifestations of this classical phenomena to the morphologies of quantum wave functions ...
