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…
Relic Neutrinos Probing Small Scale Primordial Non-Gaussianity
Suraj Gavhale, Shin'ichi Nojiri, Sergei D. Odintsov +1
Relic neutrinos retain a record of electromagnetic entropy production after neutrino decoupling, probing primordial modes erased from the primary CMB. We derive the cubic photon nu…
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…
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
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…
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…
Testing Supersymmetric Hidden Sectors with Long-Baseline Atom Interferometers
Oem Trivedi
Atomic interferometry provides a sensitive near Earth probe of high energy physics through precision measurements of quantum phase. In this Letter, we point out that MAGIS and AION…
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…
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…
Unique Gravitational-Wave Signals from Negative-Mass Binaries
Oem Trivedi, Abraham Loeb
Negative masses have long been explored, but their observational viability remains unclear. In this work, we develop a unified, observationally testable framework to constrain nega…
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…
Does Gravity Render Probability Quasilocal?
Oem Trivedi
We propose that probability in quantum theory, like energy in general relativity, acquires a fundamentally quasilocal character in curved spacetime. Interpreting Hermiticity as the…
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…
Non-Hermitian Quantum Mechanics with Applications to Gravity
Oem Trivedi, Alfredo Gurrola, Robert J. Scherrer
Hermiticity is usually treated as a foundational axiom of quantum mechanics, guaranteeing real spectra and unitary time evolution. In this work we argue that Hermiticity is more na…
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…
A Comprehensive Network for the Discovery and Characterization of Interstellar Objects
Oem Trivedi, Abraham Loeb
Interstellar object (ISO) astronomy has rapidly emerged over the past decade as a new frontier in planetary astrophysics, yet current observations remain limited by short visibilit…
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…

Ayush Bidlan, Paulo Moniz, Oem Trivedi
In this paper, we investigate the occurrence of late-time cosmological singularities, namely, the rip scenarios within the framework of interacting Fractional Holographic Dark Ener…
Inflation and Primordial Perturbations in Fractal Cosmology
Aarav Shah, Paulo Moniz, Maxim Khlopov +2
We study inflationary dynamics within the framework of fractal cosmology, where space is characterized by an effective non-integer dimension . In our work, fractal effects are s…
Future Dark Energy Constraints from Atomic Clocks
Oem Trivedi
