I’m working on the 2D extended-Hubbard model and have an idea for guessing a good initial state. To handle long cylinders, my approach is to first compute a shorter cylinder and then replicate the bulk tensor up to the desired size, assuming the bulk behavior remains similar across different sizes.
However, I’m unsure how to implement this with correct quantum number and whether it’s feasible with the current ITensors. Does anyone have experience or suggestions for achieving this?
Thanks in advance for your insights!
