Implications for Dark Matter Direct Detection in the Presence of
  LIGO-Motivated Primordial Black Holes
  We discuss formation of dark matter (DM) mini-halos around primordial black
holes (PBHs) and its implication on DM direct detection experiments, including
axion searches. Motivated by LIGO observations, we consider $f_{\textrm{DM}}
\simeq 0.01$ as the fraction of DM in PBHs with masses $10 M_{\odot} - 70
M_{\odot}$. In this case, we expect the presence of dressed PBHs after Milky
Way halo formation with mini-halo masses peaked around $M_{\textrm{halo}} \sim
(50-55) M_{\textrm{PBH}}$. We analyze the effect of tidal forces acting on
dressed PBHs within the Milky Way galaxy. In the solar neighborhood, the
mini-halos are resistant against tidal disruption from the mean-field potential
of the galaxy and encounters with stars, but they undergo a small level of
disruption caused by disk shocking. The presence of mini-halos around
LIGO-motivated PBHs today could reduce by half the local dark matter
background. High-resolution simulations are encouraged. If the proposed
scenario is realized, chances of direct detection of DM would decrease.
