Quantum superposition principle and gravitational collapse: Scattering times for spherical shells
M. Ambrus, P. Hajicek
A quantum theory of spherically symmetric thin shells of null dust and their gravitational field is studied. In Nucl. Phys. 603 (2001) 515 (hep-th/0007005), it has been shown how s…
Gauge-invariant Hamiltonian dynamics of cylindrical gravitational waves
Ioannis Kouletsis, Petr Hajicek, Jiri Bicak
The model of cylindrical gravitational waves is employed to work out and check a recent proposal in Ref. [11] how a diffeomorphism-invariant Hamiltonian dynamics is to be construct…
Canonical theory of spherically symmetric spacetimes with cross-streaming null dusts
Jiri Bicak, Petr Hajicek
The Hamiltonian dynamics of two-component spherically symmetric null dust is studied with regard to the quantum theory of gravitational collapse. The components--the ingoing and ou…
Quantum theory of gravitational collapse (lecture notes on quantum conchology)
Petr Hajicek
Preliminary version No.~2 of the lecture notes for the talk ``Quantum theory of gravitational collapse'' given at the 271. WE-Heraeus-Seminar ``Aspects of Quantum Gravity'' at Bad…
Pair of null gravitating shells III. Algebra of Dirac's observables
I. Kouletsis, P. Hajicek
The study of the two-shell system started in ``Pair of null gravitating shells I and II'' (gr-qc/0112060--061) is continued. The pull back of the Liouville form to the constraint s…
Pair of null gravitating shells II. Canonical theory and embedding variables
P. Hajicek, I. Kouletsis
The study of the two shell system started in our first paper ``Pair of null gravitating shells I'' (gr-qc/0112060) is continued. An action functional for a single shell due to Louk…
