1111.4962 (Nestor Alvarez et al.)

A local Hamiltonian for spherically symmetric gravity coupled to a
scalar field
   [PDF]

Nestor Alvarez, Rodolfo Gambini, Jorge Pullin
We present a gauge fixing of gravity coupled to a scalar field in spherical
symmetry such that the Hamiltonian is an integral over space of a local
density. Such a formulation had proved elusive over the years. As in any gauge
fixing, it works for a restricted set of initial data. We argue that the set
could be large enough to attempt a quantization the could include the important
case of an evaporating black hole.
