# Exact Beta Functions in Statistical Mechanics

I'm looking for analytically solvable models in statistical mechanics (classical or quantum) or related areas such as solid state physics in which the beta function for a certain renormalization procedure (preferably but not necessarily real space normalization) is exactly known.

I'm looking forward to your responses.

The Ising model in one and two dimensions...?

Okay:) That's certainly true. Though I would be happy to find a non-standard example that also has a phase transition (not like Ising 1D) at some point in parameter space

If you're not aware of it, you must check out Baxter's book!
