How to interpret weights of the Principal Component Analysis of the Ising model?

I'm trying to replicate the results obtained in this paper: https://arxiv.org/pdf/1606.00318.pdf . On page 3 the autors mention that the fact that the weight of the first principal component is ...

Simulation time for Ising model of large systems

I have tried to run simulation for Ising model of large-size square lattices at the critical point. Mostly I use Python optimized with numba decorator for $L=256$ it takes approx 2.5 min with ...

Critical slowing down in Monte-Carlo algorithm for classical 2D Ising Model

Why do local updates (i.e. local spin flips) near the phase transition in MC algorithm for classical 2D Ising model are said to be not "effective" and lead to incorrect critical indices? I understand ...

Critical temperature and lattice size with the Wolff algorithm for 2d Ising model

When I run my implementation of the Wolff algorithm on the square Ising model at the theoretical critical temperature I get subcritical behaviour. The lattice primarily just oscillates between mostly ...
