A matrix free action of the Ashtekar-Lewandowski volume operator of loop quantum gravity
Waleed Sherif
The Ashtekar-Lewandowski (AL) volume operator of loop quantum gravity is central to the Hamiltonian constraint, but its vertex action is usually obtained from dense spectral decomp…
Fuzzy-novae
Francesco Fazzini, Waleed Sherif
We propose a novel phenomenological model of quantum gravitational collapse inspired by loop quantum gravity that ensures a completely regular spacetime evolution. By incorporating…
Emergent Thiemann coherent states in the near-kernel sector of quantum reduced loop gravity
Ilkka Mäkinen, Hanno Sahlmann, Waleed Sherif
We study the near-kernel sector of the Hamiltonian constraint operator in the one-vertex model of quantum reduced loop gravity using variational Monte Carlo methods with neural qua…
Finding and characterising physical states of Euclidean Abelianized loop quantum gravity using neural quantum states
Hanno Sahlmann, Waleed Sherif
We study physical (near-kernel of constraints) states of 4-d Euclidean loop quantum gravity in Smolin's weak coupling limit on the complete graph using variational Monte Carl…
Deep learning spinfoam vertex amplitudes: the Euclidean Barrett-Crane model
Hanno Sahlmann, Waleed Sherif
Spinfoam theories propose a well-defined path-integral formulation for quantum gravity and are hoped to provide the dynamics of loop quantum gravity. However, it is computationally…
Towards quantum gravity with neural networks: Solving quantum Hamilton constraints of 3d Euclidean gravity in the weak coupling limit
Hanno Sahlmann, Waleed Sherif
We consider 3-dimensional Euclidean gravity in the weak coupling limit of Smolin and show that it is BF-theory with as a Lie group. The theory is quantised using lo…
Towards quantum gravity with neural networks: Solving the quantum Hamilton constraint of U(1) BF theory
Hanno Sahlmann, Waleed Sherif
In the canonical approach of loop quantum gravity, arguably the most important outstanding problem is finding and interpreting solutions to the Hamiltonian constraint. In this work…
A Fock space structure for the diffeomorphism invariant Hilbert space of loop quantum gravity and its applications
Hanno Sahlmann, Waleed Sherif
Loop quantum gravity (LQG) is a quantization program for gravity based on the principles of QFT and general covariance of general relativity. Quantum states of LQG describe gravita…
