Gerard 't Hooft
In an attempt to re-establish space-time as an essential frame for formulating quantum gravity - rather than an "emergent" one -, we find that exact invariance under scale transfor…

Entangled quantum states in a local deterministic theory
Gerard 't Hooft
Investigating a class of models that is familiar in studies of cellular automata, we find that quantum operators can be employed to describe their long distance behavior. These ope…
