Constraints on light Dark Matter evaporated from Primordial Black Hole
  through electron targets
  Light sub-GeV dark matter (DM) particles in the Milky Way or macroscopic
objects such as primordial black holes (PBHs) become attractive DM candidates
due to null results of WIMP from direct detection experiments. We explore the
possibility in which the present PBHs play as a novel source to produce light
boosted DM and confine light PBHs with current and future terrestrial
facilities. We study the electron elastic scattering data and obtain the
current constraints from Super-Kamiokande and XENON1T on the boosted DM from
PBH evaporation. The prospective bounds on the sub-GeV DM-electron scattering
cross section and the fraction of DM composed of PBHs $f_{\rm PBH}$ are also
imposed for future Xenon experiments.
