Integrability and scattering of the boson field theory on a lattice
Manuel Campos, German Sierra, Esperanza Lopez
A free boson on a lattice is the simplest field theory one can think of. Its partition function can be easily computed in momentum space. However, this straightforward solution hid…

Tensor renormalization group in bosonic field theory
Manuel Campos, German Sierra, Esperanza Lopez
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 (SVD) of continuous matr…
