(Amer Physical Soc, 2020)We consider a two-dimensional octagonal-diamond network with a fine-tuned diagonal coupling inside the diamond-shaped unit cell. Its linear spectrum exhibits coexistence of two dispersive bands (DBs) and two flat bands ...
-
(American Physical Society, 2015)The localized mode propagation in binary nonlinear kagome ribbons is investigated with the premise to ensure controlled light propagation through photonic lattice media. Particularity of the linear system characterized by ...
-
(2012)We examine localization of light in nonlinear (Kerr) kagome lattices in the shape of narrow strips of varying width. For the narrowest ribbon, the band structure features a flat band leading to linear dynamical trapping ...
-
(ELSEVIER, 2008-10-13)We study localized modes on a single Ablowitz-Ladik impurity embedded in the bulk or at the surface of a one-dimensional linear lattice. Exact expressions are obtained for the bound state profile and energy. Dynamical ...
-
(Frontiers Media, 2015)Nuclear Ca2+ is important for the regulation of several nuclear processes such as gene expression. Localized Ca2+ signals (LCSs) in skeletal muscle fibers of mice have been mainly studied as Ca2+ release events from the ...
-
(ELSEVIER SCIENCE BV, 2005-10-01)he existence, stability properties, dynamical evolution and bifurcation diagram of localized patterns and hole solutions in one-dimensional extended systems are studied from the point of view of front interactions. An ...
-
(American Physiological Society, 2015)We investigate the formation of a localized plateau beam in the transverse section of a nonlinear optical ring cavity filled with a metamaterial and a nonlocal medium such as a nematic liquid crystal. We show that, far ...
-
(1974)The effects due to localized spin fluctuations (LSF) in dilute superconducting alloys are investigated. Expressions for the critical temperature Tc as function of impurity concentration nI and the specific heat jump at the ...
-
(ELSEVIER, 2010)A time-periodic magnetic field applied transversally to the hard axis of an extended easy-plane ferromagnetic sample can produce parametric resonance. For the 2:1 resonance, the prototype orderparameter- equation derived ...
-
(AMER PHYSICAL SOC, 2008-05)We study theoretically a family of localized states which asymptotically connect a uniform oscillatory state in the magnetization of an easy-plane ferromagnetic spin chain when an oscillator magnetic field is applied ...
-
(AMERICAN PHYSICAL SOC, 2006-06)We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously ...
-
(Springer, 2017)Driven damped coupled oscillators exhibit complex spatiotemporal dynamics. An archetype model is the driven damped sine-Gordon equation, which can describe several physical systems such as coupled pendula, extended Josephson ...
-
(2005)We study numerically a prototype equation which arises generically as an envelope equa- tion for a weakly inverted bifurcation associated to traveling waves: The complex quintic Ginzburg{Landau equation. We show six di ...
-
(American Physical Society, 2015)We investigate the formation of localized structures with varying widths in one- and two-dimensional systems. The mechanism of stabilization is attributed to strongly nonlocal coupling mediated by a Lorentzian type ...
-
(Optical Soc Amer, 2020)We address the issue of nonlinear modes in a two-dimensional waveguide array, spatially distributed in the Lieb lattice geometry, and modeled by a saturable non-linear Schrodinger equation. In particular, we analyze the ...
-
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2012-02)The pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field is studied. This system is described in the continuous framework by the Landau-Lifshitz-Gilbert equation. We find ...
-
(Universidad de Chile, 2015-12)En el año 1996, tras ser detenido y fichado por la policía de investigaciones, en un allanamiento televisado a la discoteca donde trabajaba como transformista, Rodrigo (18), vuelve a su hogar con el temor de que su madre ...
-
(1995)Deuterium quadrupole splittings from the aromatic ring of a series of deuterium labeled n-alkylpyridinium ions with linear n-alkyl groups from Ci to Cie have been measured using 2H-NMR spectroscopy. These splittings were ...
-
(Springer, 2023)In Stackelberg security games, a leader locates security resources to protect a set of targets from strategic adversaries that aim to attack these targets after observing the leader’s strategy. In this setting, the leader ...
-
(American Society Enology Viticulture, 2017)The aromatic profile of monovarietal Carignan wine has been characterized, and the influence of the geographic origin of the wine on the volatile composition wines from six different zones of Chile and from two different ...
