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…
Solar System Probes for Scalar Field Dark Matter
Edmund Ghampson, Oem Trivedi, Robert J. Scherrer +1
Scalar field dark matter provides us with a well motivated alternative to conventional particle dark matter, especially when ultralight fields form coherent oscillations or compact…
Probing Dark Energy on the Moon
Alfredo Gurrola, Robert J. Scherrer, Oem Trivedi
The effective field theory (EFT) of cosmic acceleration provides a model-independent framework for describing dark energy and modified gravity, yet many of its defining operators r…
Does Cosmology require Hermiticity in Quantum Mechanics?
Oem Trivedi, Alfredo Gurrola
We explore the consequences of allowing non-Hermitian structures in quantum cosmology by extending the Wheeler DeWitt framework beyond strictly Hermitian dynamics. Using a controll…
Probing the Sound Speed of Dark Energy with a Lunar Laser Interferometer
Alfredo Gurrola, Robert J. Scherrer, Oem Trivedi
The sound speed of dark energy encodes fundamental information about the microphysics underlying cosmic acceleration, yet remains essentially unconstrained by existing observations…
