Spin networks and the big bang singularity avoidance in the AdS/CFT correspondence

Abstract

We propose a new version of the $AdS/CFT$ correspondence, where polymer structures similar to Loop Quantum Cosmology spin networks can be induced on an isotropic and homogeneous flat Randall-Sundrum II brane, corresponding to the holographic duals of closed string states living in the bulk. Such polymer structures drive a discrete evolution of the braneworld spacetime that leads to the regularization of the Big Bang singularity. The present results show that the $AdS/CFT$ conjecture can be a possible bridge between String theory and Loop Quantum Gravity.

The present article incorporates some discussions and results present in an earlier article arXiv:1707.07586v2 [gr-qc]. Published in Physical Review D
