Moving breathers in bent DNA with realistic parameters
(2004-10-30)
Recent papers have considered moving breathers (MBs) in DNA models including long range interaction due to the dipole moments of the hydrogen bonds. We have recalculated the value of the charge transfer when hydrogen ...

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, ...

Discrete soliton collisions in a waveguide array with saturable nonlinearity
(2006)
We study the symmetric collisions of two mobile breathers/solitons in a model for coupled wave guides with a saturable nonlinearity. The saturability allows the existence of mobile breathers with high power. Three main ...

Thresholds for breather solutions of the discrete nonlinear Schrödinger equation with saturable and power nonlinearity
(2008)
We consider the question of existence of periodic solutions (called breather solutions or discrete solitons) for the Discrete Nonlinear Schrödinger Equation with saturable and power nonlinearity. Theoretical and numerical ...
