Directly Deflecting Particle Dark Matter.
TLDR
In this paper, the authors proposed a new strategy to directly detect light particle dark matter that has long-ranged interactions with ordinary matter by distorting the local flow of dark matter with time-varying fields and measuring these distortions with shielded resonant detectors.Abstract:
We propose a new strategy to directly detect light particle dark matter that has long-ranged interactions with ordinary matter. The approach involves distorting the local flow of dark matter with time-varying fields and measuring these distortions with shielded resonant detectors. We apply this idea to sub-MeV dark matter particles with very small electric charges or coupled to a light vector mediator, including the freeze-in parameter space targeted by low mass direct detection efforts. This approach can probe dark matter masses ranging from 10 MeV to below a meV, extending beyond the capabilities of existing and proposed direct detection experiments.read more

Silicon carbide detectors for sub-GeV dark matter
Sinéad M. Griffin,Yonit Hochberg,Katherine Inzani,Noah Kurinsky,Noah Kurinsky,Tongyan Lin,To Chin Yu,To Chin Yu +7 more
TL;DR: In this paper, the use of silicon carbide (SiC) for direct detection of sub-GeV dark matter was proposed, which has properties similar to both silicon and diamond but has two key advantages: (i) it is a polar semiconductor which allows sensitivity to a broader range of dark matter candidates; and (ii) it exists in many stable polymorphs with varying physical properties and hence has tunable sensitivity to various dark matter models.

Cosmology of Sub-MeV Dark Matter Freeze-In
TL;DR: This work combines data from the cosmic microwave background, Lyman-α forest, quasar lensing, stellar streams, and Milky Way satellite abundances to set limits on freeze-in DM masses up to ∼20 keV, with the exact constraint depending on whether the DM thermalizes in its own sector.

TL;DR: In this article, the authors derived limits on coupling constants in the vector portal model using data from the Fermi, H.E.S.S., and IceCube detectors, and showed that these limits are set predominantly by nondetection of the upscattered DM events in XENON1T, for most of the DM mass range due to the large scattering cross-section.

SiC Detectors for Sub-GeV Dark Matter
TL;DR: SiC has properties similar to both silicon and diamond, but has two key advantages: (i) it is a polar semiconductor which allows sensitivity to a broader range of dark matter candidates; and (ii) it exists in many stable polymorphs with varying physical properties, and hence has tunable sensitivity to various dark matter models as mentioned in this paper.
