Description
Replicated geometries, both in the continuum and on the lattice, are used to study entanglement in quantum field theories. In this talk we show how to gauge the permutation symmetry of a replicated system on the lattice by introducing a background gauge field. After providing a local action for the gauge field, we discuss how this construction enables simulations of matter fields coupled to dynamical geometries, hinting at connections between entanglement and 2d quantum gravity.
