Barrier crossing driven by Levy noise: Universality and the Role of Noise Intensity
Aleksei V. Chechkin, Oleksii Yu. Sliusarenko, Ralf Metzler +1
We study the barrier crossing of a particle driven by white symmetric Levy noise of index and intensity $DD for three different generic types of potentials: (a) a bistable pote…
Breathing dynamics in heteropolymer DNA
Tobias Ambjornsson, Suman K. Banik, Oleg Krichevsky +1
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation…
Manipulating single enzymes by an external harmonic force
Michael A. Lomholt, Michael Urbakh, Ralf Metzler +1
We study a Michaelis-Menten reaction for a single two-state enzyme molecule, whose transition rates between the two conformations are modulated by an harmonically oscillating exter…
Diffusion mechanisms of localised knots along a polymer
Ralf Metzler, Walter Reisner, Robert Riehn +3
We consider the diffusive motion of a localized knot along a linear polymer chain. In particular, we derive the mean diffusion time of the knot before it escapes from the chain onc…
Fractal Dimension and Localization of DNA Knots
Erika Ercolini, Francesco Valle, Jozef Adamcik +5
The scaling properties of DNA knots of different complexities were studied by atomic force microscope. Following two different protocols DNA knots are adsorbed onto a mica surface…
Single DNA conformations and biological function
Ralf Metzler, Tobias Ambjoernsson, Andreas Hanke +2
From a nanoscience perspective, cellular processes and their reduced in vitro imitations provide extraordinary examples for highly robust few or single molecule reaction pathways.…
