Accumulation horizons and period adding in optically injected semiconductors lasers
(2007) [Artículo de periódico]We study the hierarchical structuring of islands of stable periodic oscillations inside chaotic regions in phase diagrams of single-mode semiconductor lasers with optical injection. Phase diagrams display remarkable ... -
Arithmetical signatures of the dynamics of the Hénon map
(2002) [Artículo de periódico]We report a fourth-degree polynomial that parametrizes analytically all period-4 orbits of the Hénon map and use it to investigate arithmetical signatures of the symbolic coding for this prototypical multidimensional system. ... -
Autosimilaridades en el espacio de parámetros del circuito de chua con no-linearidades discretas y continuas
(2011) [Artículo de periódico]Se muestran autosimilariades en el espacio de parámetros del circuito de Chua tanto con una no-linealidad discontinua como con una no-linealidad cúbica. Mediante un análisis sencillo de estas estructuras, se calcula de ... -
Band strength factors with asymptotic expansion for Morse-Pekeris oscillators
(1978) [Artículo de periódico]Band strength factors have been calculated by asymptotic expansion technique for N+2 (B 2 Σ+u–X 2 Σ+g) and N2(C 3πu–B 3πg) and the rotational dependences have been studied for J up to 100. A comparison between the band ... -
Basin size evolution between dissipative and conservative limits
(2005) [Artículo de periódico]Recent methods for stabilizing systems like, e.g., loss-modulated CO2 lasers, involve inducing controlled monostability via slow parameter modulations. However, such stabilization methods presuppose detailed knowledge of ... -
Calculation of rotational constants by asymptotic expasion
(1979) [Artículo de periódico]An equation has been derived for the calculation of rotational constants, Bv, using an asymptotic expansion for Morse oscillators. Bv values calculated by the new equation have been compared with those calculated numerically ... -
Caracterización de sistemas dinámicos mediante periodicidades
(2011) [Artículo de periódico]Se caracterizan diferentes sistemas din´amicos descritos por mapas mediante el c´alculo de periodicidades. Este m´etodo es alternativo a los diagramas de bifurcaci´on utilizando los exponentes de Lyapunov ya que no s´olo ... -
Chaotic particle dynamics in viscous flows: the three-particle stokeslet problem
(1997) [Artículo de periódico]It is well known, that the dynamics of small particles moving in a viscous fluid is strongly influenced by the long-range hydrodynamical interaction between them. Motion at high viscosity is usually treated by means of the ... -
Coherence in scale-free networks of chaotic maps
(2004) [Artículo de periódico]We study fully synchronized states in scale-free networks of chaotic logistic maps as a function of both dynamical and topological parameters. Three different network topologies are considered: (i) a random scalefree ... -
Einstein A coefficients, oscillator strengths and lifetimes for some selected triplet-triplet transitions of N2 : a comparison between theory and experiment
(1980) [Artículo de periódico]Einstein A coefficients, oscillator strengths and lifetimes have been calculated by an asymptotic expansion method, introduced by Chang and Karplus, for the N2, B 3Πg→A 3Σ+u (first positive), C 3Πu→B 3Πg (second positive), ... -

Evidence of homoclinic chaos in the plasma of a glow discharge
(1992) [Artículo de periódico]Homoclinic chaos is shown to occur in the electric current measured on an electrical discharge in argon. We report a clear sequence of four hesitations followed by a reverse period doubling. The experimental signals are ... -
Globally coupled multiattractor maps : mean field dynamics controlled by the number of elements
(1999) [Artículo de periódico]We report an investigation of a system of N globally coupled maps able to support multiattractors. For these systems the mean field dynamics is controlled by the number of elements in the initial partition of each basin ... -
How community size affects survival chances in cyclic competition games that microorganisms play
(2010) [Artículo de periódico]Cyclic competition is a mechanism underlying biodiversity in nature and the competition between large numbers of interacting individuals under multifaceted environmental conditions. It is commonly modeled with the popular ... -
Inducing coherence in networks of bistable maps by varying the interaction range
(2004) [Artículo de periódico]Ordinarily, two different topologies have been used to model spatiotemporal chaos and to study complexity in networks of maps: one where sites interact only with nearest neighbors (e.g., the standard diffusive coupling) ... -
Infinite hierarchies of nonlinearly dependent periodic orbits
(2001) [Artículo de periódico]Quadratic maps are used to show explicitly that the skeleton of unstable periodic orbits underlying classical and quantum dynamics is stratified into a doubly infinite hierarchy of orbits inherited from a set of basic ... -
Integrals of motion and quantum operators for hydrogenic atoms in external fields
(2000) [Artículo de periódico]We report five cases of integrability for a hydrogenic atom under three static external fields: a magnetic field, an electric field, and a van der Waals interaction. Exact integrals of motion and corresponding quantum ... -
Modeling velocity in gradient flows with coupled-map lattices with advection
(2002) [Artículo de periódico]We introduce a simple model to investigate large scale behavior of gradient flows based on a lattice of coupled maps which, in addition to the usual diffusive term, incorporates advection, as an asymmetry in the coupling ... -
Multistability, phase diagrams, and intransitivity in the Lorenz-84 low-order atmospheric circulation model
(2008) [Artículo de periódico]We report phase diagrams detailing the intransitivity observed in the climate scenarios supported by a prototype atmospheric general circulation model, namely, the Lorenz-84 low-order model. So far, this model was known ... -
Non-Shilnikov cascades of spikes and hubs in a semiconductor laser with optoelectronic feedback
(2010) [Artículo de periódico]Incomplete homoclinic scenarios were recently measured in a semiconductor laser with optoelectronic feedback. We show here that such a laser contains cascades of spirals of periodic oscillations and hubs which look identical ...
