Optimization of soliton ratchets in inhomogeneous sine-Gordon systems
F. G. Mertens, L. Morales-Molina, A. R. Bishop +2
Unidirectional motion of solitons can take place, although the applied force has zero average in time, when the spatial symmetry is broken by introducing a potential , which…
Anomalies of ac driven solitary waves with internal modes: Nonparametric resonances induced by parametric forces
Niurka R. Quintero, Angel Sanchez, Franz G. Mertens
We study the dynamics of kinks in the model subjected to a parametric ac force, both with and without damping, as a paradigm of solitary waves with internal modes. By using a…
On the existence of internal modes of sine-Gordon kinks
Niurka R. Quintero, Angel Sanchez, Franz G. Mertens
We study whether or not sine-Gordon kinks exhibit internal modes or ``quasimodes.'' By considering the response of the kinks to ac forces and initial distortions, we show that neit…
Anomalous resonance phenomena of solitary waves with internal modes
Niurka R. Quintero, Angel Sanchez, Franz G. Mertens
We investigate the non-parametric, pure ac driven dynamics of nonlinear Klein-Gordon solitary waves having an internal mode of frequency . We show that the strongest resonance…
Overdamped sine-Gordon kink in a thermal bath
Niurka R. Quintero, Angel Sanchez, Franz G. Mertens
We study the sine-Gordon kink diffusion at finite temperature in the overdamped limit. By means of a general perturbative approach, we calculate the first- and second-order (in tem…
ac driven sine-Gordon solitons: dynamics and stability
Niurka R. Quintero, Angel Sanchez
The ac driven sine-Gordon equation is studied analytically and numerically, with the aim of providing a full description of how soliton solutions behave. To date, there is much con…
