Thermally activated breakdown in a simple polymer model
S. Fugmann, I. M. Sokolov
We consider the thermally activated fragmentation of a homopolymer chain. In our simple model the dynamics of the intact chain is a Rouse one until a bond breaks and bond breakdown…
Internal friction and mode relaxation in a simple chain model
S. Fugmann, I. M. Sokolov
We consider equilibrium relaxation properties of the end-to-end distance and of principal components in a one-dimensional polymer chain model with nonlinear interaction between the…
Non-monotonic dependence of the rupture force in polymer chains on their lengths
S. Fugmann, I. M. Sokolov
We consider the rupture dynamics of a homopolymer chain pulled at one end at a constant loading rate. Our model of the breakable polymer is related to the Rouse chain, with the onl…
Resonance-like phenomena of the mobility of a chain of nonlinear coupled oscillators in a two-dimensional periodic potential
S. Martens, D. Hennig, S. Fugmann +1
We study the Langevin dynamics of a two-dimensional discrete oscillator chain absorbed on a periodic substrate and subjected to an external localized point force. Going beyond the…
Scaling in rupture of polymer chains
S. Fugmann, I. M. Sokolov
We consider the rupture dynamics of a homopolymer chain pulled at one end at a constant loading rate r. Compared to single bond breaking, the existence of the chain introduces two…
Self-organized escape of oscillator chains in nonlinear potentials
D. Hennig, S. Fugmann, L. Schimansky-Geier +1
We present the noise free escape of a chain of linearly interacting units from a metastable state over a cubic on-site potential barrier. The underlying dynamics is conservative an…
