Point force manipulation and activated dynamics of polymers adsorbed on structured substrates
P. Kraikivski, R. Lipowsky, J. Kierfeld
We study the activated motion of adsorbed polymers which are driven over a structured substrate by a localized point force.Our theory applies to experiments with single polymers us…

Barrier crossing of semiflexible polymers
P. Kraikivski, R. Lipowsky, J. Kierfeld
We consider the motion of semiflexible polymers in double-well potentials. We calculate shape, energy, and effective diffusion constant of kink excitations, and in particular their…
