Anomalies of ac driven solitary waves with internal modes: Nonparametric resonances induced by parametric forces
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2001)We study the dynamics of kinks in the φ4 model subjected to a parametric ac force, both with and without damping, as a ...

Anomalous Resonance Phenomena of Solitary Waves with Internal Modes
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2000)We investigate the nonparametric, pure ac driven dynamics of nonlinear Klein-Gordon solitary waves having an internal mode ...

Existence of internal modes of sine-Gordon kinks [Rapid Communications]
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2000)We study whether or not sine-Gordon kinks exhibit internal modes or ‘‘quasimodes.’’ By considering the response of the ...

Internal Mode Mechanism for Collective Energy Transport in Extended Systems
Sánchez Sánchez, Ángel; Quintero, Niurka R.; Mertens, Franz G.; Morales-Molina, Luis (2003)We study directed energy transport in homogeneous nonlinear extended systems in the presence of homogeneous ac forces and ...

Overdamped sine-Gordon kink in a thermal bath
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (1999)We study sine-Gordon kink diffusion at finite temperature in the overdamped limit. By means of a general perturbative ...

Reply to “Comment on ‘Existence of internal modes of sine-Gordon kinks’ ”
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2006)In this reply to the comment by C. R. Willis, we show, by quoting his own statements, that the simulations reported in his ...

Resonances in the dynamics of f 4 kinks perturbed by ac forces
Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2000)We study the dynamics of f 4 kinks perturbed by an ac force, both with and without damping. We address this issue by ...

Soliton ratchets in homogeneous nonlinear Klein-Gordon systems
Morales-Molina, Luis; Quintero, Niurka R.; Sánchez Sánchez, Ángel; Mertens, Franz G. (2006)We study in detail the ratchetlike dynamics of topological solitons in homogeneous nonlinear Klein-Gordon systems driven ...
