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…
Quantum Inequality Restrictions on Negative Energy Densities in Curved Spacetimes
Michael John Pfenning, L. H. Ford
In quantum field theory, there exist states in which the expectation value of the energy density for a quantized field is negative. These negative energy densities lead to many pro…
Quantum Inequalities and Singular Energy Densities
L. H. Ford, Michael J. Pfenning, Thomas A. Roman
There has been much recent work on quantum inequalities to constrain negative energy. These are uncertainty principle-type restrictions on the magnitude and duration of negative en…
