Mean-field phase transitions in TGFT quantum gravity
Luca Marchetti, Daniele Oriti, Andreas G. A. Pithis +1
Controlling the continuum limit and extracting effective gravitational physics are shared challenges for quantum gravity approaches based on quantum discrete structures. The descri…

Phase transitions in TGFT: a Landau-Ginzburg analysis of Lorentzian quantum geometric models
Luca Marchetti, Daniele Oriti, Andreas G. A. Pithis +1
In the tensorial group field theory (TGFT) approach to quantum gravity, the basic quanta of the theory correspond to discrete building blocks of geometry. It is expected that their…
