Quantum Mechanical Lorentzian Wormholes in Cosmological Backgrounds
David Hochberg
We present a minisuperspace analysis of a class of Lorentzian wormholes that evolves quantum mechanically in a background Friedman Robertson Walker spacetime. The quantum mechanica…

Energy Density of Non-Minimally Coupled Scalar Field Cosmologies
David Hochberg, Thomas W. Kephart
Scalar fields coupled to gravity via in arbitrary Friedmann-Robertson-Walker backgrounds can be represented by an effective flat space field theory. We derive an expressio…
