Abstract

We compute the partition function of a massive free boson in a square lattice using a tensor network algorithm. We introduce a singular value decomposition of continuous matrices that leads to very accurate numerical results. It shows the emergence of a corner double line fixed-point structure. In the massless limit, we reproduce the results of conformal field theory including a precise value of the central charge.
