Implementing XXZ model with finite DMRG
Hello, I am trying to explore the XXZ chain with DMRG to validate the performance of DMRG in an around the gapless phase. I would like to model systems with open boundary conditions and push the system sizes to see whether DMRG breaks down. I've got a few questions regarding this. 1. TeNPy has a bui...

How do I calculate an MPO using an iMPS
Given an iMPS |s \rangle , is it possible to construct an MPO corresponding to \hat{O} = | s \rangle \langle s | ? Ultimately, what I would like to do is given two iMPS objects |s \rangle , and |t \rangle , evaluate the Grover operator \hat{U}_s|t \rangle = 2 \langle s | t \rangle \ |s \rangle - | t...
