Particle creation and energy conditions for a quantized scalar field in the presence of an external, time-dependent, Mamev-Trunov potential
Michael J. Pfenning
We study the behavior of a massless, quantized, scalar field on a two-dimensional cylinder spacetime as it responds to the time-dependent evolution of a Mamev-Trunov potential of t…
Quantization of the Maxwell field in curved spacetimes of arbitrary dimension
Michael J. Pfenning
We quantize the massless p-form field that obeys the generalized Maxwell field equations in curved spacetimes of dimension n > 1. We begin by showing that the classical Cauchy prob…
Averaged null energy condition in spacetimes with boundaries
Christopher J. Fewster, Ken D. Olum, Michael J. Pfenning
The Averaged Null Energy Condition (ANEC) requires that the average along a complete null geodesic of the projection of the stress-energy tensor onto the geodesic tangent vector ca…
A Quantum Weak Energy Inequality for Spin-One Fields in Curved Spacetime
Christopher J. Fewster, Michael J. Pfenning
Quantum weak energy inequalities (QWEI) provide state-independent lower bounds on averages of the renormalised energy density of a quantum field. We derive QWEIs for the electromag…
Quantum Inequalities for the Electromagnetic Field
Michael J. Pfenning
A quantum inequality for the quantized electromagnetic field is developed for observers in static curved spacetimes. The quantum inequality derived is a generalized expression give…
Scalar, electromagnetic, and gravitational self-forces in weakly curved spacetimes
Michael J. Pfenning, Eric Poisson
We calculate the self-force experienced by a point scalar charge, a point electric charge, and a point mass moving in a weakly curved spacetime characterized by a time-independent…
