ULTRAMAN: A Proposed ultrasound detector for macroscopic dark matter
Oem Trivedi, Robert J. Scherrer, Alfredo Gurrola
We propose ULTRAMAN (ULTRAsound Macro ANalyzer), a passive ultrasound array experiment designed to search for macroscopic dark matter (macros) through coherent acoustic disturbance…
Dark Matter-Baryon Separability Predicts the Dynamics of an Almost-Dark Galaxy
Oem Trivedi, Abraham Loeb
We extend the Dark Matter-Baryon Separability Condition to show that the same framework developed for dark matter deficient galaxies naturally admits a conjugate branch describing…
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…
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…
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…
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…
Particle production and Higgs reheating
Aarav Shah, Kanabar Jay, Maxim Khlopov +2
Reheating is essential for transforming the cold, vacuum dominated Universe at the end of inflation into the hot thermal bath required by the Standard Model. In many well motivated…
Future Dark Energy Constraints from Atomic Clocks
Oem Trivedi
We show that atomic clock measurements provides an exceptionally sensitive Solar System probe of scalar tensor dark energy. By connecting variations in Newton's constant and differ…
Game Theory in Cosmology
Oem Trivedi, Venkat Venkatsubramanian
We present a game-theoretic statistical framework for cosmology, which we term \textit{Cosmological Teleodynamics}. We recast the dark sector, cosmic acceleration, large-scale stru…
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…
Gaussian Planck Relics are Ruled-Out as Dark Matter by LIGO
Oem Trivedi, Abraham Loeb
Quantum Gravity models suggest that singularities in gravitational collapse can be replaced by bounces, leading to the formation of Planck star remnants (PSR) that survive as stabl…
Cosmological Frequency Combs
Oem Trivedi, Madhurendra Mishra, Adarsh Ganesan
We identify a new class of time periodic attractor solutions in scalar field cosmology, which we term Cosmological Frequency Combs (CFC). These solutions arise in exponential quint…
The long freeze: an asymptotically static universe from holographic dark energy
Samuel Blitz, Robert J. Scherrer, Oem Trivedi
We show that some holographic dark energy models can lead to a future evolution of the universe in which the scale factor is asymptotically constant, while $\dot a \rightarrow…
New perspectives on future rip scenarios with holographic dark energy
Oem Trivedi, Robert J. Scherrer
We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale . We develop a genera…
Implications of single field inflation in general cosmological scenarios on the nature of dark energy given the swampland conjectures
Oem Trivedi
Swampland Conjectures have attracted quite some interest in the Cosmological Community. They have been shown to have wide ranging implications , like Constraints on Inflationary Mo…
