Description
There are many tensor network approaches to studying quantum field
theories. In this talk we summarize two: (1) An approach to
fine-graining (UV-completing) lattice Yang-Mills theory in the
Hamiltonian formalism. Central to this approach are local maps that
perform curvature interpolation in the gauge-group, which together
form the building blocks of a gauge-invariant MERA tensor network. (2)
A way of assigning geometric content to pieces of certain well-known
tensor networks for critical systems, via their mimicry of pieces of
euclidean time path integral (of a conformal field theory).
