Hi Miles and Matt (and any other admin), In the typical calculation of von Neumann (or Renyi) entropy, one gauge the center and then perform SVD around the gauge center (hence bipartition the chain into left/right bipartition etc) and obtain U, S, and V matrices respectively where U contains ket(a){…
