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…
