Problems with add_local_term and H.c

Hi, I'm trying to decrease the number of terms appearing in the Hamiltonian MPO by using H. c. in add_coupling_term. However, when I use plus_hc I always get an error. I have tried this with different models, and I get the same error. I provide an example below. I have a ladder of SpinHalfFermions o...

Question about the Hamiltonian MPO

Hi, thanks a lot for creating these libraries. I love the simplicity of constructing DMRG codes with them! I have a question, why do the first Hamiltonian MPO sites always have two rows instead of one? I have worked with the TNT libraries, and we use 1 row and 1 column at the first and last sites in...
