Animation of 2D Shear
2D Shear
Simple rules are written that if randomly placed particles touch when a system shears they are moved to a new position when the system is cycled back.
Critical Points
Critical Points
A critical point is the point at which the boundary that separates two stable states of matter disappears.
Fluctuations and Temperature
Fluctuations and Temperature
Coleman could see a very direct and simple relationship with the spectrum of the fluctuations and the temperature of the material.
Animation about high temperature superconductors
High Temperature Superconductors
In the first superconducting material, mercury was cooled to 4 K and 75 years later scientists made a giant leap forward as they discovered many related materials that superconduct at temperatures well above 90 K.
Neutron Scattering
Neutron Scattering
As neutrons come in contact with magnetic atoms in a material, they scatter, losing kinetic energy. This excites the magnetic fluctuations in the material.

Periodic Table: A Canvas
And the canvas that we work with is the canvas of the periodic table. We have something like 92 different elements to play with.
Quantum Critical
Quantum Critical
CeCu6Au is "quantum critical" when it fluctuates between magnetic and metallic phases. Coleman wants to understand this kind of emergent behavior.
Animation of superconductors and its properties
Superconductor Properties
Superconductors carry electrical current without resistance and are almost perfect diamagnets (a more fundamental aspect of their behavior), in that they can screen out external magnetic fields within a short distance.
G.I Taylor's experiment
Taylor's Experiment 1
Like G.I Taylor, they placed their colloid, the fluid and the particles, inside a couette cell, which consists of a cylinder with another cylinder inside it.
G.I. Taylor's Experiment 2
Taylor's Experiment 2
When Pine and Gollub ran this experiment they thought that rotating the cylinder would shear the fluid, causing some particles to collide.
