Dark matter and dark energy in combinatorial quantum gravity
Carlo A. Trugenberger
We point out that dark matter and dark energy arise naturally in a recently proposed model of combinatorial quantum gravity. Dark energy is due to the ground-state curvature at fin…
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…
Global room-temperature superconductivity in graphite
Y. V. Kopelevich, J. H. S. Torres, R. Ricardo da Silva +3
Room temperature superconductivity under normal conditions has been a major challenge of physics and material science since its very discovery. Here we report the global room-tempe…
Emergent time, cosmological constant and boundary dimension at infinity in combinatorial quantum gravity
Carlo A. Trugenberger
Combinatorial quantum gravity is governed by a discrete Einstein-Hilbert action formulated on an ensemble of random graphs. There is strong evidence for a second-order quantum phas…
Enhanced Forman curvature and its relation to Ollivier curvature
Philip Tee, C. A. Trugenberger
Recent advances in emergent geometry and discretized approaches to quantum gravity have relied upon the notion of a discrete measure of graph curvature. We focus on the two main me…
The superconductor-insulator transition in absence of disorder
M. C. Diamantini, C. A. Trugenberger, V. M. Vinokur
We provide a microscopic-level derivation of earlier results showing that, in the critical vicinity of the superconductor-to-insulator transition (SIT), disorder and localization b…
