BID - Quantum field theory with boundaries, impurities, and defects

I will introduce the on-going research program of the entanglement bootstrap, which aims to provide a mechanism by which quantum field theories may emerge from a quantum many-body system. After outlining the motivation and basic axioms concerning the fixed-point vacuum state, I will describe some of their consequences. In gapped theories satisfying an entanglement area law, the axioms imply that topological charges can be defined and transported continuously across space. Consistency rules of fusion and braiding then emerge as consequences of entanglement properties. Relaxing the axioms locally leads to natural definitions of defects and domain walls. I will conclude with some recent progress and possible future directions.
