We attack the generalized Thomson problem, i.e., determining the ground state energy and configuration of many particles interacting via an arbitrary repulsive pairwise potential on a sphere via a continuum mapping onto a universal long range interaction between angular disclination defects parametrized by the elastic (Young) modulus Y of the underlying lattice and the core energy E(core) of an isolated disclination. Predictions from the continuum theory for the ground state energy agree with…

Crystalline Particle Packings on a Sphere with Long Range Power Law Potentials
The original Thomson problem of “spherical crystallography” seeks the ground state of electron shells interacting via the Coulomb potential; however one can also study crystalline ground states of
Two-dimensional packing of soft particles and the soft generalized Thomson problem
We perform numerical simulations of a model of purely repulsive soft colloidal particles interacting via a generalized elastic potential and constrained to a two-dimensional plane and to the surface
Two and three electrons on a sphere: A generalized Thomson problem
Generalizing the classical Thomson problem to the quantum regime provides an ideal model to explore the underlying physics regarding electron correlations. In this work, we systematically investigate
Monte Carlo study of crystalline order and defects on weakly curved surfaces.
It is shown that the character and spatial distribution of defects observed in the ground state reflect the symmetries and periodicity of the two model surfaces investigated in this study.
Why charges go to the surface: A generalized Thomson problem
We study a variant of the generalized Thomson problem in which n particles are confined to a neutral sphere and interacting by a 1/rγ potential. It is found that for γ ≤ 1 the electrostatic repulsion
Defect-free global minima in Thomson's problem of charges on a sphere.
This work shows that for N approximately same or greater than 500-1000, adding dislocation defects to a symmetric icosadeltahedral lattice lowers the energy, and gives a complete or near complete catalogue of defect free global minima.
Structure and dynamics of spherical crystals characterized for the Thomson problem
Candidates for global minima of the Thomson problem for N charges on a sphere are located for N 400 and selected sizes up to N=972. These results supersede many of the lowest minima located in
Particles on curved surfaces: a dynamic approach by a phase-field-crystal model.
A dynamic model to study ordering of particles on arbitrary curved surfaces and annihilation of dislocations within the ordered system and premelting along grain-boundary scars is presented.
Structure and dynamics of topological defects in a glassy liquid on a negatively curved manifold.
It is found that the atomic configurations consist of isolated defect structures, dubbed "grain boundary scars," that form around an irreducible density of curvature-induced disclinations in an otherwise hexagonal background.
Interstitial fractionalization and spherical crystallography.
A powerful, freely-available computer program is used to explore interstitial fractionalization in some detail, for a variety of power-law pair potentials, and investigates the dependence on initial conditions and the final state energies, and compares the position dependence of interstitial energies with the predictions of continuum elastic theory on the sphere.

We propose and analyze an effective free energy describing the physics of disclination defects in particle arrays constrained to move on an arbitrary two-dimensional surface. At finite temperature
Symmetric patterns of dislocations in Thomson’s problem
Determination of the classical ground state arrangement of $N$ charges on the surface of a sphere (Thomson's problem) is a challenging numerical task. For special values of $N$ we have obtained using
Vortices in a thin-film superconductor with a spherical geometry
We report results from Monte Carlo simulations of a thin-film superconductor in a spherical geometry within the lowest-Landau-level approximation. We observe the absence of a phase transition to a

It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
