coniii.ising.automaton module

class coniii.ising.automaton.Ising2D(dim, J, h=0, rng=None)[source]

Bases: object

Simulation of the ferromagnetic Ising model on a 2D periodic lattice with quenched disorder in the local fields.

iterate(n_iters, systematic=True)[source]
Parameters:

  • n_iters (int)
