Hi there, - Ah - add_coupling is repeated automatically over the sites. It seems to be working now thanks !!

Update ... sorry for the spam but at least I understood something ... judging by https://github.com/tenpy/tenpy/blob/main/tenpy/networks/terms.py#L707-L742 which has ... def add_coupling_term(self, strength, i, j, op_i, op_j, op_string='Id'): """Add a two-site coupling term on given M...

Addendum --- If I manually add the nearest neighbor couplings class Field(CouplingModel, NearestNeighborModel): def __init__(self): # Define the lattice with custom sites site = Qumode() lattice = Chain(lattice_size, site=site, bc='periodic') # Use open boundary conditions super().__init__(lattice) ...

Hi there -- I have a problem defining nearest neighbor models. I'm still in the discovery phase of TeNPy so please be gentle. Here is my code .. class Field(CouplingModel, NearestNeighborModel): def __init__(self): # Define the lattice with custom sites site = Qumode() lattice = Chain(lattice_size, ...
