Energy localization and shape transformations in semiflexible polymer rings
Yuri B. Gaididei, Juan F. R. Archilla, Víctor J. Sánchez-Morcillo +1
Shape transformations in driven and damped molecular chains are considered. Closed chains of weakly coupled molecular subunits under the action of spatially homogeneous time-period…
Long-range effects on superdiffusive solitons in anharmonic chains
C. Brunhuber, F. G. Mertens, Y. Gaididei
Studies on thermal diffusion of lattice solitons in Fermi-Pasta-Ulam (FPU)-like lattices were recently generalized to the case of dispersive long-range interactions (LRI) of the Ka…
Thermal diffusion of solitons on anharmonic chains with long-range coupling
C. Brunhuber, F. G. Mertens, Y. Gaididei
We extend our studies of thermal diffusion of non-topological solitons to anharmonic FPU-type chains with additional long-range couplings. The observed superdiffusive behavior in t…
Localization of nonlinear excitations in curved waveguides
Yu. B. Gaididei, P. L. Christiansen, P. G. Kevrekidis +2
Motivated by the example of a curved waveguide embedded in a photonic crystal, we examine the effects of geometry in a ``quantum channel'' of parabolic form. We study the linear ca…
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…
