MPO-MPS contraction using apply
Hello all, I have an operator which is the summation of the annihilation operator of fermions and each term in the summation has a different coefficient. = \sum a_{i}* c_{i, \up} since we should consider the Jordan Wigner string, it is not possible to use the onsite function so I try to construct th...

How to add Jordan-Wigner strings on the left sites of an operator?
Dear Johannes, I have got a question about constructing wave packets in Tenpy. I want to study the time evolution of the Fermi Hubbard model in the paper :"https://journals.aps.org/prl/supplemental/10.1103/PhysRevLett.114.066401/paper4_sm.pdf" and construct the following operator: h_{\sigm...
