Tension dynamics in semiflexible polymers. Part I: Coarse-grained equations of motion [PDF]

open access: yes, 2006
Based on the wormlike chain model, a coarse-grained description of the nonlinear dynamics of a weakly bending semiflexible polymer is developed. By means of a multiple scale perturbation analysis, a length-scale separation inherent to the weakly-bending ...

Homogenization of the nonlinear bending theory for plates [PDF]

open access: yes, 2013
We carry out the spatially periodic homogenization of nonlinear bending theory for plates. The derivation is rigorous in the sense of Gamma-convergence. In contrast to what one naturally would expect, our result shows that the limiting functional is not ...

Curvature-induced symmetry breaking in nonlinear Schrodinger models [PDF]

open access: yes, 2000
We consider a curved chain of nonlinear oscillators and show that the interplay of curvature and nonlinearity leads to a symmetry breaking when an asymmetric stationary state becomes energetically more favorable than a symmetric stationary state. We show
