A generalized growth model based on nonadditive entropy
I. Rondón, O. Sotolongo-Costa, J. A. González +1
We present a general growth model based on non-extensive statistical physics is presented. The obtained equation is expressed in terms of nonadditive entropy. We show that the…
Stability of bubble-like fluxons in disk-shaped Josephson junctions in the presence of a coaxial dipole current
Alicia G. Castro-Montes, Mónica A. García-Ñustes, Jorge A. González +2
We investigate analytically and numerically the stability of bubble-like fluxons in disk-shaped heterogeneous Josephson junctions. Using ring solitons as a model of bubble fluxons…
Arbitrarily large numbers of kink internal modes in inhomogeneous sine-Gordon equations
J. A. González, A. Bellorín, M. A. García-Ñustes +3
We prove the existence of an infinite number of internal (shape) modes of sine-Gordon solitons in the presence of some inhomogeneous long-range forces, provided some conditions are…
Bubble-like structures generated by activation of internal shape modes in two-dimensional sine-Gordon line solitons
Mónica A. García-Ñustes, Jorge A. González, Juan F. Marín
Nonlinear waves that collide with localized defects exhibit complex behavior. Apart from reflection, transmission, and annihilation of an incident wave, a local inhomogeneity can a…
Diverse routes to oscillation death in a coupled oscillator system
J. J. Suarez-Vargas, J. A. Gonzalez, A. Stefanovska +1
We study oscillation death (OD) in a well-known coupled-oscillator system that has been used to model cardiovascular phenomena. We derive exact analytic conditions that allow the p…
Universal functions and exactly solvable chaotic systems
M. A. Garcia-Nustes, Emilio Hernandez-Garcia, Jorge A. Gonzalez
A universal differential equation is a nontrivial differential equation the solutions of which approximate to arbitrary accuracy any continuous function on any interval of the real…
