Quantum Gravitational Force Between Polarizable Objects
L. H. Ford, Mark P. Hertzberg, J. Karouby
Since general relativity is a consistent low energy effective field theory, it is possible to compute quantum corrections to classical forces. Here we compute a quantum correction…
Probability distributions for quantum stress tensors in four dimensions
Christopher J. Fewster, L. H. Ford, Thomas A. Roman
We treat the probability distributions for quadratic quantum fields, averaged with a Lorentzian test function, in four-dimensional Minkowski vacuum. These distributions share some…
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…
The unphysical nature of "Warp Drive"
Michael J. Pfenning, L. H. Ford
We will apply the quantum inequality type restrictions to Alcubierre's warp drive metric on a scale in which a local region of spacetime can be considered ``flat''. These are inequ…
Quantum Field Theory Constrains Traversable Wormhole Geometries
L. H. Ford, Thomas A. Roman
Recently a bound on negative energy densities in four-dimensional Minkowski spacetime was derived for a minimally coupled, quantized, massless, scalar field in an arbitrary quantum…
Averaged Energy Conditions and Evaporating Black Holes
L. H. Ford, Thomas A. Roman
In this paper the averaged weak (AWEC) and averaged null (ANEC) energy conditions, together with uncertainty principle-type restrictions on negative energy (``quantum inequalities'…
