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…
Thermal Gravitons from Warm Inflation
Gabriele Montefalcone, Barmak Shams Es Haghi, Tao Xu +1
In warm inflation (WI), the persistent thermal bath that is sustained by dissipative interactions with the inflaton field produces a stochastic background of gravitational waves (G…
Blue Loops, Cepheids, and Forays into Axions
Kaleb Anderson, Thomas C. Gehrman, Pearl Sandick +3
The blue loop stage of intermediate mass stars has been called a "magnifying glass", where even seemingly small effects in prior stages of evolution, as well as assumptions about s…
Dancing with invisible partners: Three-body exchanges with primordial black holes
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
The abundance of massive primordial black holes has historically been constrained by dynamical probes. Since these objects can participate in hard few-body scattering processes, th…
Hawking Radiation of Nonrelativistic Scalars: Applications to Pion and Axion Production
Hao-Ran Cui, Yuhsin Tsai, Tao Xu
In studying secondary gamma-ray emissions from Primordial Black Holes (PBHs), the production of scalar particles like pions and axion-like particles (ALPs) via Hawking radiation is…
Detecting Light Dark Matter with Kinetic Inductance Detectors
Jiansong Gao, Yonit Hochberg, Benjamin V. Lehmann +4
Superconducting detectors are a promising technology for probing dark matter at extremely low masses, where dark matter interactions are currently unconstrained. Realizing the pote…
Leptogenesis with dynamical couplings
Peisi Huang, Tao Xu
We propose a novel leptogenesis mechanism with a temperature-dependent coupling between the right-handed neutrino and Standard Model particles. This coupling experiences suppressio…
Recycled Dark Matter
Thomas C. Gehrman, Barmak Shams Es Haghi, Kuver Sinha +1
We outline a new production mechanism for dark matter that we dub "recycling": dark sector particles are kinematically trapped in the false vacuum during a dark phase transition; t…
