Global Asymptotics, the Swampland Conjectures, and Preheating of String Moduli
Leia Price, Kuver Sinha, Robert Wiley Deal
While the cosmological implications of the Swampland Conjectures are usually discussed in the context of inflationary model building, they also have implications for the violent, n…
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…
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…
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…
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…
