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…
DNA Spools under Tension
I. M. Kulic, H. Schiessel
DNA-spools, structures in which DNA is wrapped and helically coiled onto itself or onto a protein core are ubiquitous in nature. We develop a general theory describing the non-equi…
Where the linearized Poisson-Boltzmann cell model fails: (I) spurious phase separation in charged colloidal suspensions
M. N. Tamashiro, H. Schiessel
We perform a linearization of the Poisson-Boltzmann (PB) density functional for spherical Wigner-Seitz cells that yields Debye-Hückel-like equations agreeing asymptotically with th…
Electrostatically induced undulations of lamellar DNA-lipid complexes
H. Schiessel, H. Aranda-Espinoza
We consider DNA-cationic lipid complexes that form lamellar stacks of lipid bilayers with parallel DNA strands intercalated in between. We calculate the electrostatically induced e…
