Effective de Sitter space, quantum behaviour and large-scale spectral dimension (3+1)
Carlo A. Trugenberger
De Sitter space-time, essentially our own universe, is plagued by problems at the quantum level. Here we propose that Lorentzian de Sitter space-time is not fundamental but constit…
Emergence of the Circle in a Statistical Model of Random Cubic Graphs
Christy Kelly, Carlo Trugenberger, Fabio Biancalana
We consider a formal discretisation of Euclidean quantum gravity defined by a statistical model of random -regular graphs and making using of the Ollivier curvature, a coarse an…
Quantum magnetic monopole condensate
M. C. Diamantini, C. A. Trugenberger, V. M. Vinokur
Despite decades-long efforts, magnetic monopoles were never found as elementary particles. Monopoles and associated currents were directly measured in experiments and identified as…
Combinatorial Quantum Gravity: Emergence of Geometric Space from Random Graphs
C. Kelly, C. A. Trugenberger
We review and extend the recently proposed model of combinatorial quantum gravity. Contrary to previous discrete approaches, this model is defined on (regular) random graphs and is…
Combinatorial Quantum Gravity: Geometry from Random Bits
Carlo A. Trugenberger
I propose a quantum gravity model in which geometric space emerges from random bits in a quantum phase transition driven by the combinatorial Ollivier-Ricci curvature and correspon…
Critical Space-Time Networks and Geometric Phase Transitions from Frustrated Edge Antiferromagnetism
Carlo A. Trugenberger
Recently I proposed a simple dynamical network model for discrete space-time which self-organizes as a graph with Hausdorff dimension d_H=4. The model has a geometric quantum phase…
