Vacuum polarization and stress-energy of a quantum field inside of two-dimensional black holes
Paul R. Anderson, Amanda Peake, Shohreh Gholizadeh Siahmazgi
Quantum effects are studied in both Schwarzschild spacetime and a spacetime in which a null shell collapses to form a black hole via the vacuum polarization a…
Late-time behaviors of scalar field modes for a collapsing null shell spacetime and for the Unruh state in Schwarzschild spacetime
Shohreh Gholizadeh Siahmazgi, Paul R. Anderson, Alessandro Fabbri
The behaviors of the modes for a massless minimally coupled scalar field are investigated for the Unruh state for Schwarzschild spacetime and the "in" vacuum state for a spacetime…
Solutions to the mode equation for a quantized massless scalar field outside a black hole that forms from the collapse of a null shell: Late-time behaviors and computation of the stress-energy tensor
Shohreh Gholizadeh Siahmazgi
The late-time behaviors of the modes in the Unruh state for various eternal two-dimensional black holes are discussed. The Unruh state is designed to be a state that mimics the lat…
Stress-energy Tensor for a Quantized Scalar Field in a Four-Dimensional Black Hole Spacetime that Forms From the Collapse of a Null Shell
Shohreh Gholizadeh Siahmazgi, Paul R. Anderson, Raymond D. Clark +1
A method is presented which allows for the numerical computation of the stress-energy tensor for a quantized massless minimally coupled scalar field in the region outside the event…
