Enhanced dumbbell diffusion in a periodic potential by the elevator effect
B. A. Kiang, H. Schiessel
We present molecular dynamics simulations of the random walk of a dumbbell - two beads connected by a spring - in a one-dimensional periodic potential and compare our results in li…

Statistical Mechanics of Multiplectoneme Phases in DNA
Midas Segers, Enrico Skoruppa, Helmut Schiessel +1
A stretched DNA molecule which is also under- or overwound, undergoes a buckling transition forming intertwined looped domains called plectonemes. Here we develop a simple theory t…

Systematic Coarse-Graining of Sequence-Dependent Structure and Elasticity of Double-Stranded DNA
Enrico Skoruppa, Helmut Schiessel
Coarse-grained models have played an important role in the study of the behavior of DNA at length scales beyond a few hundred base pairs. Traditionally, these models have relied on…
