Query: Dequantization of electric charge: Probing scenarios of cosmological
  multi-component dark matter   Since the electric charge in the standard model is theoretically not
quantized, we may have a variant of it, called dark charge. Similar to the
electric charge, the dark charge neither commutes nor closes algebraically with
$SU(2)_L$. The condition of algebraic closure leads to a novel gauge extension,
$SU(2)_L \otimes U(1)_Y \otimes U(1)_N$, where $Y$ and $N$ determine the
electric and dark charges, respectively, apart from the color group. We argue
that the existence of the dark charge, thus $N$, leads to the novel scenarios
of multi-component dark matter, in general. The dark matter stability is
determined by a residual (or dark charge) gauge symmetry isomorphic to an even
$Z_k$ discrete group, where $k$ is specified dependent on the value of the
neutrino dark charge. This residual symmetry divides the standard model
particles into distinct classes, which possibly accommodate dark matter, but
the dark matter candidate cannot decay due to the color and electric charge
conservation. We analyze in detail three specific models according to $k=2,4,6$
and determine the simplest dark matter candidates. For small $U(1)_N$ coupling,
the two-component dark matter scenarios implied by the dark charge successfully
explain the dark matter relic density and the recent XENON1T excess, as well as
the beam dump, neutrino scattering, and astrophysical bounds. Otherwise, for
large $U(1)_N$ coupling, we have multi-WIMPs coexisted beyond the weak scale.
