Quantum gravity and the Coulomb potential
Viqar Husain, Jorma Louko, Oliver Winkler
We apply a singularity resolution technique utilized in loop quantum gravity to the polymer representation of quantum mechanics on R with the singular -1/|x| potential. On an equis…
Semiclassical states for quantum cosmology
Viqar Husain, Oliver Winkler
In a metric variable based Hamiltonian quantization, we give a prescription for constructing semiclassical matter-geometry states for homogeneous and isotropic cosmological models.…
Quantum Hamiltonian for gravitational collapse
Viqar Husain, Oliver Winkler
Using a Hamiltonian formulation of the spherically symmetric gravity-scalar field theory adapted to flat spatial slicing, we give a construction of the reduced Hamiltonian operator…
Flat slice Hamiltonian formalism for dynamical black holes
V. Husain, O. Winkler
We give a Hamiltonian analysis of the asymptotically flat spherically symmetric system of gravity coupled to a scalar field. This 1+1 dimensional field theory may be viewed as the…
Quantum black holes from null expansion operators
Viqar Husain, Oliver Winkler
Using a recently developed quantization of spherically symmetric gravity coupled to a scalar field, we give a construction of null expansion operators that allow a definition of ge…
Semiclassical Quantum Gravity: Statistics of Combinatorial Riemannian Geometries
Luca Bombelli, Alejandro Corichi, Oliver Winkler
This paper is a contribution to the development of a framework, to be used in the context of semiclassical canonical quantum gravity, in which to frame questions about the correspo…
