I have a question for OP @evanb, or anyone else who's knowledgeable on this: Are ideas from tensor networks (eg: how the relevant degrees of freedom are organized), or even neural networks for that matter, applied to lattice gauge theories? In the other direction, is it understood how to implement states of gauge theories as tensor networks?
I'm aware of Elitzur's theorem (that there is no local gauge invariant order parameter), but I'm afraid I do not know much about lattice gauge theories.
- evanb 11y agoI don't know much about tensor networks, so I may not be the right person to answer your question. Maybe that's answer enough? I would guess that it would only be apparent how to do some kind of embedding like you're thinking about after fixing a gauge, so that there would be gauge configurations that are physically equivalent but not at all manifestly related to the network you're interested in. I do know that people think about tensor networks seriously as toy models for quantum gravity. But that's quite outside my range of expertise.
