Negative Power Spectra in Quantum Field Theory
Jen-Tsung Hsiang, Chun-Hsien Wu, L. H. Ford
We consider the spatial power spectra associated with fluctuations of quadratic operators in field theory, such as quantum stress tensor components. We show that the power spectrum…
Quantum Modifications to Gravity Waves in de Sitter Spacetime
Jen-Tsung Hsiang, L. H. Ford, Da-Shin Lee +1
We treat a model in which tensor perturbations of de~Sitter spacetime, represented as a spatially flat model, are modified by the effects of the vacuum fluctuations of a massless c…
Probability distributions of smeared quantum stress tensors
Christopher J. Fewster, L. H. Ford, Thomas A. Roman
We obtain in closed form the probability distribution for individual measurements of the stress-energy tensor of two-dimensional conformal field theory in the vacuum state, smeared…
