| DESCRIPTION:
Colliding Lattices simulates the interaction
of charged particles in two dimensions. The particles
interact via the classical Coulomb force, as well as
the repulsive quantum-mechanical Pauli force, which
acts at close distances (accounting for the "collisions"
between them). Additionally, the motion of the particles
is damped by a term proportional to their velocity,
allowing them to "settle down" into stable
(or meta-stable) states.
In this program, you can observe the results of a collision
between two rectangular lattices of variable dimensions
and initial velocities. After selecting a dimension,
position, and velocity for each, click the "Start"
button to run the simulation. Depending on your initial
conditions, the two lattices may combine in to one larger
lattice, or perhaps some more exotic formation. Experiment
with various values and see what happens, although note
that collisions above a certain speed will likely cause
the particles to annihilate! The simulation is fully
interactive, so feel free to manipulate the particles
as they evolve.
New feature: Selecting a particle and pressing
"f" will toggle fieldlines illustrating the
local field around that particle. Performance varies
depending on the number of particles / fieldlines in
the simulation.
