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…
Escape angles in bulk chi(2) soliton interactions
Steffen Kjaer Johansen, Ole Bang, Mads Peter Soerensen
We develop a theory for non-planar interaction between two identical type I spatial solitons propagating at opposite, but arbitrary transverse angles in quadratic nonlinear (or so-…
Nonlinearity and disorder: Classification and stability of nonlinear impurity modes
Andrey A. Sukhorukov, Yuri S. Kivshar, Ole Bang +2
We study the effects produced by competition of two physical mechanisms of energy localization in inhomogeneous nonlinear systems. As an example, we analyze spatially localized mod…
Parametric localized modes in quadratic nonlinear photonic structures
Andrey A. Sukhorukov, Yuri S. Kivshar, Ole Bang +1
We analyze two-color spatially localized modes formed by parametrically coupled fundamental and second-harmonic fields excited at quadratic (or chi-2) nonlinear interfaces embedded…
Multi-component optical solitary waves
Yuri S. Kivshar, Andrey A. Sukhorukov, Elena A. Ostrovskaya +5
We discuss several novel types of multi-component (temporal and spatial) envelope solitary waves that appear in fiber and waveguide nonlinear optics. In particular, we describe mul…
