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 ...

... Physically, when these terms are small, the atoms undergo a Majorana spin flip as J0 ðΩR =ωÞ changes sign but are able to adiabatically follow when they are nonzero. Because α, δ ∝ J0 ðΩR =ωÞ change sign simultaneously, the qx ’s for the local minima in E− ðqx Þ associated with each spin state do no ...
