I've been recently learning about numerical methods in physics, and have come across matrix product states and tensor networks. This is definitely a vague question, but I was wondering if anyone knew of any places where I could find code examples (or pseudocode examples) for simple systems like the Ising Model, (low site) Hubbard model, or XXZ model.

I'm specifically trying to build familiarity with ITensors and Julia, but any resources would be greatly appreciated!

ITensor has many tutorials published here. Please let know if there's something more you'd need which lacks from this page.
