چکیده

We explore the topology of configuration spaces of hard disks experimentally and show that several changes in the topology can already be observed with a small number of particles. The results illustrate a theorem of Baryshnikov, Bubenik, and Kahle that critical points correspond to configurations of disks with balanced mechanical stresses and suggest conjectures about the asymptotic topology as the number of disks tends to infinity.

Computational Dynamics and Topology

Locking configuration of hard balls (disks) in box (square) The archetypal dynamical system of statistical physics, the hard frictionless balls in a box (Boltzmann gas) has been studied for a century. Yet the basic question about the topology of these spaces – are these spaces connected? – is unanswered, in the physically interesting and important gaseous regime (when nr →∞, but nr2 → 0). In pr...

A Computational Topology Approach to Hard Spheres in a Box

As an attempt to better understand the physical properties of atoms and how they interact together on a quantum level, physicists have looked toward models based upon hard spheres for insight. Similar in spirit to the underpinnings of the Boltzmann model, the hard spheres model sets a foundation upon which to frame this topic and begin to tackle interesting problems. In order to simplify matter...

The Homology of the Little Disks Operad

This expository paper aims to be a gentle introduction to the topology of configuration spaces, or equivalently spaces of little disks. The pantheon of topological spaces which beginning graduate students see is limited – spheres, projective spaces, products of such, perhaps some spaces such as Lie groups, Grassmannians or knot complements. We would like for Euclidean configuration spaces to be...

Discrete configuration spaces of squares and hexagons

We consider generalizations of the familiar fifteen-piece sliding puzzle on the 4 by 4 square grid. On larger grids with more pieces and more holes, asymptotically how fast can we move the puzzle into the solved state? We also give a variation with sliding hexagons. The square puzzles and the hexagon puzzles are both discrete versions of configuration spaces of disks, which are of interest in s...

Effect of Magnetic Field on the Rotating Flow in a Similar Czochralski Configuration

We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz).  The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...
