Biological semiflexible polymers and filaments such as collagen, fibronectin, actin,
microtubules, coiled-coil proteins, DNA, siRNA, amyloid fibrils, etc., are ubiquitous in nature …

We propose a simple mean-field theory for the structure of ring polymer melts. By combining
the notion of topological volume fraction and a classical van der Waals theory of fluids, we …

The combination of ring closure and spatial constraints has a fundamental effect on the
statistics of semiflexible polymers such as DNA. However, studies of the interplay between …

The constraints due to the chain closure in combination with the geometrical constraints of a
DNA molecule are inevitable for many biological processes. In this work, structural …

The segmental relaxation dynamics of ring polymers in dilute solutions, with both repulsive
excluded volume interactions (EVI) and attractive interactions, is investigated through Rouse …

Understanding the mechanism of DNA extension in nanochannels is necessary for
interpretation of experiments in nanofluidic channel devices that have been conducted …

The conformational and dynamical properties of active ring polymers are studied by
numerical simulations. The two-dimensionally confined polymer is modeled as a closed …

We study structural properties of a ring polymeric melt confined in a film in comparison to a
linear counterpart using molecular dynamics simulations. Local structure orderings of ring …

The conformational behavior and spatial organization of self-avoiding semi-flexible ring
polymers, that are fully adsorbed on solid substrates, are investigated via systematic coarse …

Physical properties of ring polymers are subjected to topological constraint, understanding
of which has been a significant challenge as a fundamental problem in polymer science …
