Heisenberg model with just next-nearest-neighbor interaction
I want to consider model with sublattice A and B, but only interactions of AA BB ABA, when I test the Heisenberg model with next-nearest-neighbor interaction I found the result is not right. My code is following: class Heisenberg(MultiCouplingModel, MPOModel): def __init__(self, model_params): # L =...
