Johannes , thank you! That source code is very helpful. I think I understand how to deal with anisotropic J and single-ion anisotropy. However, I am lost regarding incorporating DMI. I have the DMI vector D = (Dx,Dy,Dz), and this vector is different depending on the spin site chosen. I have a trian...

Hi, Currently, I am able to run DMRG calculations for the CouplingMPOModel with isotropic exchange J parameters J1 and J2 for NN, and NNN using: def init_terms(self, model_params): J1 = model_params.get('J1', 1.0) J2 = model_params.get('J2', 0.0) for u1, u2, dx in self.lat.pairs['nearest_neighbors']...

Hi, I started using TeNPy just a few days ago, and I appreciate all the work being done on it. Please forgive me for the following long, beginner questions, but I wasn't sure where else to go to for help. 1) I want to use DMRG to find the magnetic ground state on a triangular lattice for a spin-1/2 ...
