A Stepping Stone Solution to the QCD Axion Isocurvature Problem
Kun-Feng Lyu, Kuver Sinha
We propose a ''stepping stone'' realization of the varying Peccei Quinn (PQ) scale solution to the QCD axion isocurvature problem. In conventional implementations, suppressing isoc…
Entanglement, Yang-Mills, and the Scattering Matrix as an SU(N)-equivariant Kernel
Kun-Feng Lyu, Rahul Muraleedharan, Kuver Sinha
We study two-body scattering as an SU(N)-equivariant map acting on tensor-product representation spaces and analyze the entanglement generated by the -matrix. This representatio…
Quantum Semiconductor Heterostructures for meV Axion Dark Matter Detection
Jaanita Mehrani, Tao Xu, Andrey Baydin +6
We propose a novel strategy and a new class of detectors for the direct detection of axion dark matter in the meV mass range, based on resonantly enhanced axion-photon conversion t…
From Fluctuation to Polarization: Imprints of Curvature Perturbations in CMB B-modes from Scalar-Induced Gravitational Waves
Aurora Ireland, Kuver Sinha, Tao Xu
Probing primordial curvature perturbations on small scales, beyond those accessible using cosmic microwave background (CMB) primary anisotropies and Lyman- forest data, remains…
Fast and Fewrious: Stochastic binary perturbations from fast compact objects
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
Massive compact objects soften binaries. This process has been used for decades to constrain the population of such objects, particularly as a component of dark matter (DM). The ef…
New Constraints on Neutrino-Dark Matter Interactions: A Comprehensive Analysis
P. S. Bhupal Dev, Doojin Kim, Deepak Sathyan +2
We present a comprehensive analysis of the interactions of neutrinos with the dark sector within the simplified model framework. We first derive the exact analytic formulas for the…
