abstract
Very recently, the Xenon1T collaboration has reported an intriguing electron recoil excess, which may imply for light dark matter. In order to interpret this anomaly, we propose the atmospheric dark matter (ADM) from the inelastic collision of cosmic rays (CRs) with the atmosphere. Due to the boost effect of high energy CRs, we show that the light ADM can be fast-moving and successfully fit the observed electron recoil spectrum through the ADM-electron scattering process. Meanwhile, our ADM predicts the scattering cross section $\sigma_e \sim {\cal O}(10^{-38}- 10^{-39}$) cm$^{2}$, and thus can evade other direct detection constraints. The search for light meson rare decays, such as $\eta \to \pi + \slashed E_T$, would provide a complementary probe of our ADM in the future.

Probing Supernova Neutrino Boosted Dark Matter with Collective Excitation
Galactic supernova neutrino boosted dark matter can produce plasmon excitations in silicon detectors, improving sub-MeV dark matter sensitivity by 3 to 4 orders of magnitude over Super-K.

Inelastic Scattering Effects on Attenuation of Boosted Dark Matter
Resonant excitation of nucleons into Δ(1232) during Earth passage is a non-negligible attenuation channel for boosted dark matter at E_χ ≈ 1–2 GeV, lowering the PandaX-4T upper bound on σ̄_n in the heavy-mediator regime.

Direct detection of solar chameleons with electron recoil data from XENONnT
XENONnT electron-recoil data bound solar chameleons to log10 β_eff < −6.9, independent of the potential index n for inverse power-law chameleons at the dark-energy scale.
