Re: Charge Info for Z3 symmetry in 3-state Potts Model

I have played around with various Zn models using Tenpy. You can usually find an equivalent model which has a nice diagonal symmetry by interchanging Z and X (or Omega and Gamma). I believe interchanging Z and X can be described as a local coordinate transformation, and doesn't affect the physics. E...

Infinite DMRG convergence in a critical region

Hi, I'm attempting to do some infinite DMRG calculations with the Superintegrable Chiral Potts model (spin chain version). However I'm having difficulty getting DMRG to converge in the critical region. I've attached some example code, which should demonstrate the problem directly. It has some other ...
