The static and dynamic properties of ring polymers in concentrated solutions remains one of
the last deep unsolved questions in polymer physics. At the same time, the nature of the …

All life forms are miraculous, but some are more inexplicable than others. Trypanosomes are
by far one of the most puzzling organisms on Earth: their mitochondrial genome, also called …

We use computer simulations to study a system of two unlinked ring polymers, whose length
and bending stiffness are systematically varied. We derive the effective potentials between …

Ring polymers in dense solutions are among the most intriguing problems in polymer
physics. Because of its natural occurrence in circular form, DNA has been extensively used …

While the behavior of vesicles in thermodynamic equilibrium has been studied extensively,
how active forces control vesicle shape transformations is not understood. Here, we …

We perform large scale three-dimensional molecular dynamics simulations of unlinked and
unknotted ring polymers diffusing through a background gel, here a three-dimensional cubic …

DNA recombination is a ubiquitous process that ensures genetic diversity. Contrary to
textbook pictures, DNA recombination, as well as generic DNA translocations, occurs in a …

We employ extensive computer simulations to investigate the conformations and the
interactions of ring polymers under conditions of worsening solvent quality, in comparison …

We investigate with numerical simulations the molecular origin of viscosity in melts of flexible
and semiflexible oligomer rings in comparison to the corresponding systems with linear …

Cellular locomotion often involves the motion of thin, elastic filaments, such as cilia and
flagella, in viscous environments. The manuscript serves as a general introduction to the …
