Model for gravitational collapse in effective quantum gravity
Andreas Kreienbuehl, Viqar Husain, Sanjeev S. Seahra
We describe a non-perturbative approach to studying the gravitational collapse of a scalar field in spherical symmetry with quantum gravity corrections. Quantum effects are describ…
Dust reference frame in quantum cosmology
Viqar Husain, Tomasz Pawlowski
We give a formulation of quantum cosmology with a pressureless dust and arbitrary additional matter fields. The system has the property that its Hamiltonian constraint is linear in…
Time and a physical Hamiltonian for quantum gravity
Viqar Husain, Tomasz Pawlowski
We present a non-perturbative quantization of general relativity coupled to dust and other matter fields. The dust provides a natural time variable, leading to a physical Hamiltoni…
Gravitational collapse of quantum matter
Benjamin K. Tippett, Viqar Husain
We describe a class of exactly soluble models for gravitational collapse in spherical symmetry obtained by patching dynamical spherically symmetric exterior spacetimes with cosmolo…
