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 …
Linear Response Analysis of the Semiclassical Approximation to Spin 1/2 Quantum Electrodynamics in 1+1 Dimensions
Ian M. Newsome, Paul R. Anderson, Eric M. Grotzke
An investigation of the validity of the semiclassical approximation to quantum electrodynamics in 1+1 dimensions is given. The criterion for validity used here involves the impact…
Looking for traces of Hawking radiation in correlation functions of BEC acoustic black holes
Paul R. Anderson, Roberto Balbinot, Richard A. Dudley +1
Renaud Parentani was one of the leading figures in Quantum Field Theory in curved spacetime, in particular concerning its applications to Hawking-like radiation in analogue models.…
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…
Quantum Effects in 3+1 Schwarzschild-de Sitter Spacetime: Properties of the Hadamard Function
Ian M. Newsome, Silvia Pla, Paul R. Anderson
In a four-dimensional Schwarzschild-de Sitter background, the spherically symmetric contribution to the Hadamard two-point correlation function is computed for a massles…
The fine structure of the peaks of the correlation function in acoustic black holes: a complete analytical model
Paul R. Anderson, Roberto Balbinot, Richard A. Dudley +3
The detailed structure of the peaks appearing in the density-density correlation function for an acoustic black hole formed by a Bose-Einstein condensate is analytically discussed…
