Intersection of crisis loci in a driven nonlinearly damped oscillator
Palmero Acebedo, Faustino; Romero Romero, Francisco; Romero Romero, Juan Luis; Archilla, Juan F. R. (Elsevier, 1995)We report on a phenomenon observed in a driven nonlinearly damped oscillator when two control parameters, the frequency ...

Localized oscillations in nonlinear hamiltonian Klein-Gordon lattices. Breathers and Anderson modes
Cuevas-Maraver, Jesús; Palmero Acebedo, Faustino; Archilla, Juan F. R.; Romero Romero, Francisco; Muriel, M.C. (2002)There are two different sources of localization in discrete lattices: • Anderson modes in disordered harmonic lattices [1] • Discrete breathers in homogeneous nonlinear lattices [2]

Lower and upper estimates on the excitation threshold for breathers in DNLS lattices
Cuevas-Maraver, Jesús; Karachalios, Nikolaos I.; Palmero Acebedo, Faustino (2009)We propose analytical lower and upper estimates on the excitation threshold for breathers (in the form of spatially localized ...
