  A system of light axions comprising a classical axion field, one candidate
for dark matter, has an instability that can rapidly mix in photon pairs in a
coherent fashion if initiated by a quantum break (which eliminates the need for
seeds.) Adding more photon states, such as a multiplicity of angles for the
case of the axion field at rest, reduces the argument of a logarithmic factor
in the mixing time by orders of magnitude. Admitting multiple photon states,
all within a window of instability, leads to a synchronization effect that
appears to nullify conventional red-shift limitations. Even the fully developed
states of the electromagnetic field produced are highly non-classical; they can
be looked on as quantum superpositions of different nearly-classical
macroscopic systems.
