Classical and quantum nonlinear localized excitations in discrete systems
(Transworld Research Network, 2005)
Discrete breathers, or intrinsic localized modes, are spatially localized, time–periodic, nonlinear excitations that can exist and propagate in systems of coupled dynamical units. Recently, some experiments show the ...

Breather trapping and breather transmission in a DNA model with an interface
(2006)
We study the dynamics of moving discrete breathers in an interfaced piecewise DNA molecule. This is a chain in which all the base pairs are identical and there exists a discontinuity in the orientation of the dipole moments ...

Discrete moving breather collisions in a Klein-Gordon chain of oscillators
(2008)
We study the collisions of moving breathers with the same frequency, traveling with opposite directions within a Klein–Gordon chain of oscillators. Two types of collisions have been analyzed: symmetric and non-symmetric, ...
