Vortex motion in a finite-size easy-plane ferromagnet and application to a nanodot
Denis D. Sheka, Juan P. Zagorodny, Jean-Guy Caputo +2
We study the motion of a non-planar vortex in a circular easy-plane ferromagnet, which imitates a magnetic nanodot. Analysis was done using numerical simulations and a new collecti…
Bubble generation in a twisted and bent DNA-like model
Peter V. Larsen, Peter L. Christiansen, Ole Bang +2
The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investig…
Energy funneling in a bent chain of Morse oscillators with long-range coupling
P. V. Larsen, P. L. Christiansen, O. Bang +2
A bent chain of coupled Morse oscillators with long-range dispersive interaction is considered. Moving localized excitations may be trapped in the bending region. Thus chain geomet…
Transparency Resonances and Bound States of the Junction
P. L. Christiansen, A. V. Zolotaryuk, V. N. Ermakov +1
Exact positive and negative energy solutions for the eigenvalue problem of the Schrödinger equation in one dimension with a interaction are found and analyzed. An infini…
Models for energy and charge transport and storage in biomolecules
Serge F. Mingaleev, Peter L. Christiansen, Yuri B. Gaididei +2
Two models for energy and charge transport and storage in biomolecules are considered. A model based on the discrete nonlinear Schrodinger equation with long-range dispersive inter…
Effects of long-range dispersion in nonlinear dynamics of DNA molecules
Yuri B. Gaididei, Serge F. Mingaleev, Peter L. Christiansen +2
A discrete nonlinear Schrodinger (NLS) model with long-range dispersive interactions describing the dynamical structure of DNA is proposed. Dispersive interactions of two types: th…
