Mechanistic models of -synuclein homeostasis for Parkinson's disease: A blueprint for therapeutic intervention
Elena Righetti, Alice Antonello, Luca Marchetti +2
Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide, yet there is no disease-modifying therapy up to this date. The biological complexity underl…
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…
Effective dynamics of scalar cosmological perturbations from quantum gravity
Luca Marchetti, Daniele Oriti
We derive an effective dynamics for scalar cosmological perturbations from quantum gravity, in the framework of group field theory (GFT) condensate cosmology. The emergent spacetim…
Impact of a modified Entropy-Area law on Schwarzschild-de Sitter metric
Luca Marchetti, Giancarlo Cella
Based on the perspective that continuum gravitational physics is an emergent quantum gravitational phenomenon, and that spacetime thermodynamic is the natural langauge in which it…
Phase transitions in tensorial group field theories: Landau-Ginzburg analysis of models with both local and non-local degrees of freedom
Luca Marchetti, Daniele Oriti, Andreas G. A. Pithis +1
In the tensorial group field theory approach to quantum gravity, the theory is based on discrete building blocks and continuum spacetime is expected to emerge from their collective…
Effective cosmology from one-body operators in group field theory
Steffen Gielen, Luca Marchetti, Daniele Oriti +1
We propose a new method for obtaining an effective Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology from the quantum gravity dynamics of group field theory (GFT), based on the…
Quantum fluctuations in the effective relational GFT cosmology
Luca Marchetti, Daniele Oriti
We analyze the size and evolution of quantum fluctuations of cosmologically relevant geometric observables, in the context of the effective relational cosmological dynamics of GFT…
Effective relational cosmological dynamics from Quantum Gravity
Luca Marchetti, Daniele Oriti
We discuss the relational strategy to solve the problem of time in quantum gravity and different ways in which it could be implemented, pointing out in particular the fundamentally…
