You’ve now succesfully implemented the RG approach for the 2D Ising model. Congratulations! It is an interesting exercise to try the same approach for the 1D Ising model (where you should find no phase transition) and the 3D Ising model (where you should also be able to compute the critical exponent \(\nu\) as described below. …
