Reduced Hamiltonian for intersecting shells and Hawking radiation
arXiv:0912.3873 · doi:10.1088/1742-6596/222/1/012051
Abstract
We consider the dynamics of one or more self gravitating shells of matter in a centrally symmetric gravitational field in the Painleve' family of gauges. We give the reduced hamiltonian for two intersecting shells, both massless and massive. Such a formulation is applied to the computation of the semiclassical action of two intersecting shells. The relation of the imaginary part of the space-part of the action to the computation of the Bogoliubov coefficients is revisited.
