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

TL;DR

This paper introduces a novel $AdS/CFT$ framework incorporating spin network-like structures from Loop Quantum Cosmology on a brane, which regularizes the Big Bang singularity and links string theory with Loop Quantum Gravity.

Contribution

It proposes a new $AdS/CFT$ correspondence with polymer structures that induce a discrete, singularity-free evolution of the brane universe.

Findings

Polymer structures lead to a regularized Big Bang.

The framework connects string theory and Loop Quantum Gravity.

Discrete evolution replaces classical singularity.

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.
