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…
Simple Mechanical Equivalents of Stepping Rotary Dynamics in F-ATPase
A. V. Zolotaryuk, V. N. Ermakov, P. L. Christiansen +2
Two simple (rotator and one-particle) mechanistic models are suggested to describe simultaneously at a minimal level of sophistication two basic functions of F-ATPase: a motor…
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…
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…
Quantum nonlinear lattices and coherent state vectors
Demosthenes Ellinas, Magnus Johansson, Peter L Christiansen
Quantized nonlinear lattice models are considered for two different classes, boson and fermionic ones. The quantum discrete nonlinear Schroedinger model (DNLS) is our main objectiv…
