We consider a model for periodic patterns of charges constrained over a cylindrical surface. In particular we focus on patterns of chiral helices, achiral rings, or vertical lamellae, with the constraint of global electroneutrality. We study the dependence of the patterns' size and pitch angle on the radius of the cylinder and salt concentration. We obtain a phase diagram by using numerical and analytic techniques. For pure Coulomb interactions, we find a ring phase for small radii and a chiral…

Electrostatics and optimal arrangement of ionic triangular lattices confined to cylindrical fibers.
It is shown that varying the stoichiometric composition of charges, as well as including higher-order curvature effects, does not significantly modify such a scenario, and that a different family of achiral lattices is always preferred.
Packing of charged chains on toroidal geometries.
It is found that the electrostatic energy of confined chains on tori conforms to a power law regardless of the screening effect in some typical cases studied, and uniform packing, which breaks the mirror symmetry the least, has the lowest value of the order parameter.
Chiral surfaces self-assembling in one-component systems with isotropic interactions.
We show that chiral symmetry can be broken spontaneously in one-component systems with isotropic interactions, i.e., many-particle systems having maximal a priori symmetry. This is achieved by
Surface patterning of low-dimensional systems: the chirality of charged fibres.
A simple model effectively predicting some features of chiral patterns in biological systems is presented and is extended from helical lamellar patterns to elliptical patterns to consider asymmetrical patterns in assemblies of filamentous aggregates.
Electrostatic-driven pattern formation in fibers, nanotubes and pores
The physical properties of interfaces between media with different dielectric permittivities are modified by the adsorption of charged particles. The adsorbed charges can be arranged into
The electrostatic origin of chiral patterns on nanofibers
Several recent research works focus on nanofibers covered by molecules that self-assemble into chiral helices. While the formation of helical structures has been explained mostly on a case by case
Ion condensation on charged patterned surfaces.
The conditions for the appearance of more complex ionic patterns by considering simple perturbations of the stripe-centered and dipolar array structures are determined.
Self-assembly of charged particles on nanotubes and the emergence of particle rings, chains, ribbons and chiral sheets
A diverse range of supramolecular assembly processes arise from the competition between directional and isotropic intermolecular interactions. Directional interactions often have a charge origin or
Confined Assemblies of Colloidal Particles with Soft Repulsive Interactions.
The experimentally observed assembly morphologies are consistent with theoretical predictions from the literature, based on Yukawa potential in the low packing density regime, and most of the configurations found in the experiment are well described by computer simulations using pairwise additive long-range repulsive interactions.
Tunable soft structure in charged fluids confined by dielectric interfaces
Electrolyte-induced forces between neutral objects are described, finding the forces to be sensitively dependent on the material properties of the charged fluid and the immersed solutes.
