A quantum Bose-Hubbard model with evolving graph as toy model for emergent spacetime
Alioscia Hamma, Fotini Markopoulou, Seth Lloyd +3
We present a toy model for interacting matter and geometry that explores quantum dynamics in a spin system as a precursor to a quantum theory of gravity. The model has no a priori…

Fractal Dimension in 3d Spin-Foams
Francesco Caravelli, Leonardo Modesto
In this paper we perform the calculation of the spectral dimension of the space-time in 3d quantum gravity using the dynamics of the Ponzano-Regge vertex (PR) and its quantum group…
