Quantum collapse of a thin shell revisited

Erratum: Quantum gravitational collapse of a charged dust shell

A simple self gravitating system—a thin spherical shell of charged pressureless matter— is naively quantized as a test case of quantum gravitational collapse. The model is interpreted in terms of an inner product on the positive energy states. An S-matrix is constructed describing scattering between negatively and positively infinite radius.

Gravitational Collapse of a Radiating Shell

We study the collapse of a self-gravitating and radiating shell. Matter constituting the shell is quantized and the construction is viewed as a semiclassical model of possible black hole formation. It is shown that the shell internal degrees of freedom are excited by the quantum non-adiabaticity of the collapse and, consequently, on coupling them to a massless scalar field, the collapsing matte...

Charged Rotating Black Hole Formation from Thin Shell Collapse in Three Dimensions

The thin shell collapse leading to the formation of charged rotating black holes in 2+1 dimensions is analyzed in the light of a recently developed Hamiltonian formalism for these systems. It is proposed to demand, as a natural extension of what happens with a solenoid in flat space, that the magnetic field should vanish just outside the shell. The adoption of this boundary condition results in...

Gravitational Collapse of a Shell of Quantized Matter

The semi-classical collapse, including lowest order back-reaction, of a thin shell of self-gravitating quantized matter is illustrated. The conditions for which selfgravitating matter forms a thin shell are first discussed and an effective Lagrangian for such matter is obtained. The matter-gravity system is then quantized, the semiclassical limit for gravitation is taken and the method of adiab...
