Axion dark matter search using the storage ring EDM method
  We propose using the storage ring EDM method to search for the axion dark
matter induced EDM oscillation in nucleons. The method uses a combination of B
and E-fields to produce a resonance between the $g-2$ spin precession frequency
and the background axion field oscillation to greatly enhance sensitivity to
it. An axion frequency range from $10^{-9}$ Hz to 100 MHz can in principle be
scanned with high sensitivity, corresponding to an $f_a$ range of $10^{13} $
GeV $\leq f_a \leq 10^{30}$ GeV, the breakdown scale of the global symmetry
generating the axion or axion like particles (ALPs).
