Electric fields and quantum wormholes
... Notably, while it clearly resonates well with holographic ideas [14–29], this “ER ¼ EPR” proposal is more general in that it makes no reference to gauge-gravity duality. The entangled quantum fields here exist already in a theory of dynamical gravity rather than in a holographically dual field theor ...

Indeed, it turns out that most perturbation series are divergent, i.e. their convergence radius vanishes. This divergence of perturbation serie ...
