Semiclassical Gravity in the Far Field Limit of Stars, Black Holes, and Wormholes
Eric D. Carlson, Paul R. Anderson, Alessandro Fabbri +3
Semiclassical gravity is investigated in a large class of asymptotically flat, static, spherically symmetric spacetimes including those containing static stars, black holes, and wo…
Effects of Quantized Scalar Fields in Cosmological Spacetimes with Big Rip Singularities
Jason D. Bates, Paul R. Anderson
Effects of quantized free scalar fields in cosmological spacetimes with Big Rip singularities are investigated. The energy densities for these fields are computed at late times whe…
Cosmological Horizon Modes and Linear Response in de Sitter Spacetime
Paul R. Anderson, Carmen Molina-Paris, Emil Mottola
Linearized fluctuations of quantized matter fields and the spacetime geometry around de Sitter space are considered in the case that the matter fields are conformally invariant. Ta…
Excision boundary conditions for the conformal metric
Gregory B. Cook, Thomas W. Baumgarte
Shibata, Uryū and Friedman recently suggested a new decomposition of Einstein's equations that is useful for constructing initial data. In contrast to previous decompositions, the…
Stress Tensor from the Trace Anomaly in Reissner-Nordstrom Spacetimes
Paul R. Anderson, Emil Mottola, Ruslan Vaulin
The effective action associated with the trace anomaly provides a general algorithm for approximating the expectation value of the stress tensor of conformal matter fields in arbit…
Measuring eccentricity in binary black-hole initial data
Jason D. Grigsby, Gregory B. Cook
Initial data for evolving black-hole binaries can be constructed via many techniques, and can represent a wide range of physical scenarios. However, because of the way that differe…
