The Classical Singularity Theorems and their Quantum Loopholes
L. H. Ford
The singularity theorems of classical general relativity are briefly reviewed. The extent to which their conclusions might still apply when quantum theory is taken into account is…
What does Quantum Field Theory in Curved Spacetime Have to Say about the Dark Energy?
L. H. Ford
The issue of the vacuum energy of quantum fields is briefly reviewed. It is argued that this energy is normally either much too large or much too small to account for the dark ener…
Stress Tensor Fluctuations and Passive Quantum Gravity
L. H. Ford, Chun-Hsien Wu
The quantum fluctuation of the stress tensor of a quantum field are discussed, as are the resulting spacetime metric fluctuations. Passive quantum gravity is an approximation in wh…
Quantum Lightcone Fluctuations in Theories with Extra Dimensions
Hongwei Yu, L. H. Ford
The effects of small extra dimensions upon quantum fluctuations of the lightcone are examined. We argue that compactified extra dimensions modify the quantum fluctuations of gravit…
Quantum Field Theory in Curved Spacetime
L. H. Ford
These lectures deal with selected aspects of quantum field theory in curved spacetime including the following topics: (1) Quantization of fields on a curved background, particle cr…
