  In this work, we propose a novel scenario to probe the interactions between
dark matter (DM) particles and electrons, via hydrogen-atmosphere pulsating
white dwarfs (DAVs) in globular clusters. In this special configuration, the DM
particles, which are predominantly captured by multiple scattering with the
electrons in a DAV, would annihilate by pairs and provide extra energy source
to the DAV. This mechanism slows down the natural cooling evolution which can
be presented by the period variation rates of pulsation modes. The differences
between the secular rates predicted by the precise asteroseismology and the
secular rates obtained from observation can reveal the DM-electron
interactions. An important observable has been proposed and corresponding
estimations have been made. According to the estimation, if this scenario could
be implemented in the near future, the potential sensitivity on $m_{\chi}$ (DM
particle's mass) and $\sigma_{\chi,e}$ (elastic scattering cross section
between DM and electron) could be hopefully extended to a region $5
\mathrm{GeV} \lesssim m_{\chi} \lesssim 10^{4} \mathrm{GeV}$ and
$\sigma_{\chi,e} \gtrsim 10^{-40} \mathrm{cm}^{2}$. Combining with indirect DM
detection results, this could give us a cross check on the existence of such
leptonphilic DM particles to some extent.
