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…
The Complete Barrett-Crane Model and its Causal Structure
Alexander F. Jercher, Daniele Oriti, Andreas G. A. Pithis
The causal structure is a quintessential element of continuum spacetime physics and needs to be properly encoded in a theory of Lorentzian quantum gravity. Established spin foam (a…
Emergent Cosmology from Quantum Gravity in the Lorentzian Barrett-Crane Tensorial Group Field Theory Model
Alexander F. Jercher, Daniele Oriti, Andreas G. A. Pithis
We study the cosmological sector of the Lorentzian Barrett-Crane (BC) model coupled to a free massless scalar field in its Group Field Theory (GFT) formulation, corresponding to th…
