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 ...

Soliton stability criterion for generalized nonlinear Schrödinger equations
Quintero, Niurka R.; Mertens, Franz G.; Bishop, Alan R. (American Physical Society, 2015)A stability criterion for solitons of the driven nonlinear Schrödinger equation (NLSE) has been conjectured. The criterion ...

Time-shift invariance determines the functional shape of the current in dissipative rocking ratchets
Cuesta, José Antonio; Quintero, Niurka R.; Álvarez Nodarse, Renato (2013)Ratchets are devices that are able to rectify an otherwise oscillatory behavior by exploiting an asymmetry of the system. ...

Using the finite domain remnant of the continuous spectrum to examine integrability: Effect of boundary conditions
Quintero, Niurka R.; Kevrekidis, Panayotis G. (2003)The aim of this work is to propose a method for testing the integrability of a model partial differential (PDE) and/or ...
