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…
Dark Matter Deficient Galaxies as Probes of Dark Matter
Oem Trivedi, Abraham Loeb
Dark matter deficient galaxies provide a direct way to test whether baryons and dark matter can become sufficiently separated during galaxy evolution. We formulate a Dark Matter-Ba…
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…
Solar System and Atomic Clock Bounds on Locally Coupled Swampland Scalars
Suraj Gavhale, Maxim Khlopov, Oem Trivedi +1
We study how local measurements constrain light scalar fields that are relevant in late time cosmic acceleration and are often discussed in connection with swampland criteria. Star…
Nonlinear Dynamical Regimes of Cosmological Frequency Combs
Madhurendra Mishra, Oem Trivedi, Adarsh Ganesan
We study the emergence of Cosmological Frequency Combs (CFCs) in a quintessence cosmology with an exponential potential using a dynamical systems formulation. Expressing the evolut…
Non-Markovian Memory-Induced Effects in Quantum Cosmology
Aarav Shah, Paulo Moniz, Oem Trivedi +1
We study memory effects in quantum cosmology by extending the semiclassical Wheeler-DeWitt framework beyond its usual local form. The main idea is to introduce a causal memory kern…
