Pearson’s Results

In 1991 Pearson, calculated the exact partition function for the 4x4x4 Ising model. Plotting Pearson’s results against my own. I also managed to calculate this using my program, the results are compared

Pearson vs. Yogi

This page displays my results against R.B Pearsons.

Zero Distribution of 4 state Potts Models

Below are zero distributions for the 3 x 4 x 10 Potts lattice model with Q = 4. This is for the purpose of taking a closer look at boundary conditions. The dimesions are height x width x depth

Zero Distribution of 5 state Potts Models

Below are zero distributions for the 3 x 3 x 10 Potts lattice model with Q = 5. This is for the purpose of taking a closer look at boundary conditions. The dimesions are height x width x depth

A closer look at the zero’s pinching the real axis

On this page we take a closer look at the “pinch” of the two outer arms of zeros on the real axis. A plot of the anti-ferromagnetic zeros of a 5x5x10 lattice with q=2 is shown below. The parametric graph f(x(t), y(t)) = acos(t)(1+cos(t+k)) + b, csin(t)(1+cos(t+k))+d is also plotted. Where a, b, c, d and k are real value constants.
