We calculate the black hole entropy in Loop Quantum Gravity as a function of the horizon area and provide the exact formula for the leading and sub-leading terms. By comparison with the Bekenstein-Hawking formula we uniquely fix the value of the 'quantum of area' in the theory.

  1. Gauging Time Reversal Symmetry in Quantum Gravity: Arrow of Time from a Confinement--Deconfinement Transition

    physics.gen-ph 2026-05 unverdicted novelty 6.0

    The emergence of the cosmological arrow of time is identified with a confinement-deconfinement transition in a Z2 lattice gauge theory on LQG spin networks, with the deconfined phase corresponding to a CZX-type SPT phase.

  2. Scalar$-$Tensor Gravity as a Probe of Generalized Black Hole Entropy

    gr-qc 2026-05 unverdicted novelty 5.0

    Links generalized black hole entropies to scalar-tensor gravity via Misner-Sharp mass and Wald entropy, yielding distinct scalar potentials with cosmological implications.
