We give a brief overview of the properties of a higher dimensional generalization of matrix model which arises naturally in the context of a background independent approach to quantum gravity, the so called group field theory. We show that this theory leads to a natural proposal for the physical scalar product of quantum gravity. We also show in which sense this theory provides a third quantization point of view on quantum gravity.

  1. Collective excitations in quantum gravity condensates

    gr-qc 2026-05 unverdicted novelty 6.0

    Collective excitations analogous to phonons are derived in quantum gravity condensates within a group field theory model, yielding leading beyond-mean-field corrections to emergent Friedmann dynamics.

  2. A Cosmological Uncertainty Relation and Late-Universe Acceleration

    astro-ph.CO 2026-04 unverdicted novelty 6.0

    A deformed uncertainty relation for the universe scale factor modifies the Friedmann equation to yield late-universe acceleration or a bounce according to the sign of a single free exponent.

  3. A Cosmological Uncertainty Relation and Late-Universe Acceleration

    astro-ph.CO 2026-04 unverdicted novelty 4.0

    Deformed commutation relation for the cosmic scale factor modifies the Friedmann equation to produce late-time dark energy with w > -1 or a non-singular bounce as a horizon-scale quantum gravity effect, without new pa...
