Hyperinvariant Spin Network States -- An AdS/CFT Model from First Principles
Fynn Otto, Refik Mansuroglu, Norbert Schuch +2
We study the existence and limitations of hyperinvariant tensor networks incorporating a local SU(2) symmetry. As discrete implementations of the anti de-Sitter/conformal field the…
