By means of extensive computer simulations, we investigate the formation of columnar structures (stacks) in concentrated solutions of semiflexible ring polymers. To characterize the stacks we employ an algorithm that identifies tube-like structures in the simulation cell. Stacks are found both in the real system and in the fluid of soft disks interacting through the effective anisotropic pair potential derived for the rings [P. Poier et al., Macromolecules, 2015, 48, 4983-4997]. Furthermore, we…

Concentration-induced planar-to-homeotropic anchoring transition of stiff ring polymers on hard walls.
TLDR
It is discovered that by increasing density one can induce a reorientation of the effective rings in the vicinity of a wall, which prefer to orient themselves parallel to the surface for low densities ρ and reorient orthogonal to the wall (edge-on or homeotropic) for higher values of ρ.
Ring polymers are much stronger depleting agents than linear ones
ABSTRACT We investigate the conformations and shapes of circular polymers close to planar, hard walls as well as the ensuing ring–wall and polymer-induced wall–wall interactions in ring polymer…
Cluster prevalence in concentrated ring-chain mixtures under shear.
TLDR
This work investigates the impact of mixing linear chains and rings in a similar system under shear, studying clustering in the presence of semiflexible, rod-like chains, and presents a correlation between chain monomer fraction and clustering behavior.
Ordered aggregation of semiflexible ring-linear blends in ellipsoidal confinement
A comparative study of semi-flexible linear and ring polymer conformational change in an anisotropic environment.
TLDR
The formation of an ordered parallel arrangement of the environment can effectively lead to a remarkable stretching effect on the probed polymer and the coupling between the crowding anisotropy-induced stretching and the polymer stiffness can account for the unusual swelling behavior.
Entropy-Induced Separation of Binary Semiflexible Ring Polymer Mixtures in Spherical Confinement
TLDR
These explicit segregated structures of the two components in spherical confinement are induced by a delicate competition between the entropic excluded volume (depletion) effects and bending contributions.

An Anisotropic Effective Model for the Simulation of Semiflexible Ring Polymers
TLDR
This work derives and introduces anisotropic effective pair potentials to coarse-grain solutions of semiflexible ring polymers of various lengths and demonstrates that for the short- and intermediate-length rings the new model is quite capable of capturing the physics in a quantitative fashion, whereas for the largest rings, which resemble flexible ones, it fails at high densities.
Fluids of semiflexible ring polymers: effective potentials and clustering
We present a computational investigation of the structural properties of a fluid of semiflexible ring polymers. Stiffness is introduced by implementing intramolecular barriers. Because of these…
Cluster Glasses of Semiflexible Ring Polymers
TLDR
The results reveal a novel scenario of glass formation in a simple monodisperse system, characterized by self-collective decoupling, soft caging, and mild dynamic heterogeneity.
Molecular dynamics simulation study of nonconcatenated ring polymers in a melt. I. Statics.
TLDR
Molecular dynamics simulations were conducted to investigate the structural properties of melts of nonconcatenated ring polymers and compared to melts of linear polymers, finding an overall conformation of a crumpled globule.
Architecture-Induced Size Asymmetry and Effective Interactions of Ring Polymers: Simulation and Theory
TLDR
A phenomenological theory is proposed for the effective interactions between rings, modeling them as unequal-sized penetrable spheres, which rationalizes the non-Gaussian shape and the short-distance plateau observed in the effective potential between unknotted ring polymers and pairs of unequal- sized unknots/knotted ones.
Influence of topology on effective potentials: coarse-graining ring polymers
We employ computer simulations and integral equation theory techniques to perform coarse-graining of self-avoiding ring polymers with different knotedness and to derive effective interaction…
Statistics of polymer rings in the melt: a numerical simulation study.
TLDR
In order to access the relatively large chain lengths required to observe significant effects, an efficient, on-lattice Monte Carlo model is implemented allowing for fast relaxation thanks to non-local moves which randomly displace kinks along the polymer contour.
Multi-blob coarse graining for ring polymer solutions.
TLDR
It is demonstrated that the pair structure between the centers of mass of the rings is accurately reproduced by the multi-blob approach, thus opening the way for simulation of arbitrarily long polymers.
Influence of solvent quality on effective pair potentials between polymers in solution.
TLDR
The resulting effective pair potential is found to depend strongly on temperature and polymer concentration, and at low concentration the effective interaction becomes increasingly attractive as the temperature decreases, eventually violating thermodynamic stability criteria.
Tunable effective interactions between dendritic macromolecules.
TLDR
This work employs extensive Monte Carlo and molecular-dynamics simulations to investigate the effective interactions between the centers of mass of dendritic macromolecules of variable flexibility and generation number and finds that the effective potentials have a generic Gaussian shape.
