First-principles upper bounds on dark matter-electron scattering rates from condensed matter sum rules
Bradford A. Barker, Jay Epstein, Luke James +5
A wide variety of condensed matter systems are used or proposed as detectors to search for dark matter-electron scattering. In general, the scattering rate depends on detailed know…
Electronic Direct Detection of Light Dark Matter with Intermediate-Mass Mediators
Connor Stratman, Tanner Trickle
Recent years have seen dramatic improvements in the sensitivity of electron-based direct detection experiments. Typically, the sensitivity to dark matter scattering is determined i…
Infrared Freeze-In of Magnetic Dipole Dark Matter
Asher Berlin, Jae Hyeok Chang, Tanner Trickle
We propose a novel mechanism for the cosmological production of keV - GeV mass dark matter that interacts with the Standard Model through a small effective magnetic dipole moment.…
A Thermal Relic Encyclopedia: Dark Matter Candidates Coupled to Quarks
Dan Hooper, Gordan Krnjaic, Tanner Trickle +1
Thermal freeze-out is a compelling framework for naturally generating the dark matter abundance. We systematically study a broad range of dark matter and mediator particle combinat…
Determining Spin-Dependent Light Dark Matter Rates from Neutron Scattering
Asher Berlin, Alexander J. Millar, Tanner Trickle +1
The scattering and absorption rates of light dark matter with electron spin-dependent interactions depend on the target's spin response. We show how this response is encoded by the…
MOSAIC: Magnonic Observations of Spin-dependent Axion-like InteraCtions
Clarence Chang, T. J. Hobbs, Dafei Jin +6
We introduce an array-scalable, magnon-based detector (MOSAIC) to search for the spin-dependent interactions of electron-coupled axion dark matter. These axions can excite single m…
