Dark Energy in the Plane
Oem Trivedi, Robert J. Scherrer, Alfredo Gurrola
We introduce a unified framework for dark energy diagnostics based on the joint phase space of the equation of state and the sound speed . The resulting plane…
Exact general solutions for cosmological scalar field evolution in a vacuum-energy dominated expansion
Patrick Hu, Robert J. Scherrer
The paper derives exact general solutions for the evolution of a cosmological scalar field in a universe dominated by vacuum energy (w_B = -1), covering several potential forms and…
Solar System Probes for Scalar Field Dark Matter
Edmund Ghampson, Oem Trivedi, Robert J. Scherrer +1
The paper proposes three Solar System and local Galactic observational methods—flaring events from scalar clump encounters with Kuiper Belt objects, atomic clock searches for oscil…
Apocalypse When? Solar System Constraints on an Imminent Big Rip
Robert J. Scherrer, Oem Trivedi
Phantom dark energy models with an equation of state parameter lead generically to a future big rip singularity, in which the dark energy density becomes infinite in a fin…
Dark Matter from Holography
Oem Trivedi, Robert J. Scherrer
Previous studies have examined the holographic principle as a means of producing dark energy. Here we propose instead the possibility of holographic dark matter. In this case, dark…
Smoking Gun Signatures of Quasilocal Probability in Black Hole Ringdowns
Oem Trivedi, Alfredo Gurrola, Robert J. Scherrer
Building on recent work introducing the idea of Quasilocal Probability in curved spacetime, we develop its observational implications for black hole ringdown in detail. We show tha…
