Discrete kink dynamics in hydrogen-bonded chains I: The one-component model
V. M. Karpan, Y. Zolotaryuk, P. L. Christiansen +1
We study topological solitary waves (kinks and antikinks) in a nonlinear one-dimensional Klein-Gordon chain with the on-site potential of a double-Morse type. This chain is used to…
Stationary and moving breathers in a simplified model of curved alpha--helix proteins
J. F. R. Archilla, Yu B. Gaididei, P. L. Christiansen +1
The existence, stability and movability of breathers in a model for alpha-helix proteins is studied. This model basically consists a chain of dipole moments parallel to it. The exi…
Nonclassical statistics of intracavity coupled waveguides: the quantum optical dimer
M. Bache, Yu. B. Gaididei, P. L. Christiansen
A model is proposed where two nonlinear waveguides are contained in a cavity suited for second-harmonic generation. The evanescent wave coupling between the waveguides is…
Quasi-Periodic and Periodic Solutions for Systems of Coupled Nonlinear SCHRÖdinger Equations
P. L. Christiansen, J. C. Eilbeck, V. Z. Enolskii +1
We consider travelling periodic and quasiperiodic wave solutions of a set of coupled nonlinear Schrödimger equations. In fibre optics these equations can be used to model single mo…
Quasiperiodic Solutions of the Fibre Optics Coupled Nonlinear Schr{ö}dinger Equations
P L Christiansen, J C Eilbeck, V Z Enolskii +1
We consider travelling periodical and quasiperiodical waves in single mode fibres, with weak birefringence and under the action of cross-phase modulation. The problem is reduced to…
