Deep Learning on the 2-Dimensional Ising Model to Extract the Crossover Region with a Variational Autoencoder

no code implementations28 May 2020 Nicholas Walker, Ka-Ming Tam

The 2-dimensional Ising model on a square lattice is investigated with a variational autoencoder in the non-vanishing field case for the purpose of extracting the crossover region between the ferromagnetic and paramagnetic phases.
