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…
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…
Validity of the Semiclassical Approximation in 1+1 Electrodynamics: Numerical Solutions to the Linear Response Equation
Ian M. Newsome
From previous work arXiv:2010.09811, the semiclassical backreaction equation in 1+1 dimensions was solved and a criterion was implemented to assess the validity of the semiclassica…
Pair production due to an electric field in 1+1 dimensions and the validity of the semiclassical approximation
Silvia Pla, Ian M. Newsome, Robert S. Link +2
Solutions to the backreaction equation in 1+1-dimensional semiclassical electrodynamics are obtained and analyzed when considering a time-varying homogeneous electric field initial…
