  We determine the evolving segregated or mixed morphology of charged-particle
systems with long-range power-law interactions and overall charge neutrality
that have been quenched to a low temperature. Segregated morphology systems are
characterized by the size of uniformly charged domains, $L(t)$, the particle
separation within the domains, $l_{AA}(t)$, the particle flux-density leaving
the domains, $J(t)$, the width of reaction zones between domains, $W(t)$, the
particle spacing within the reaction-zones, $l_{AB}(t)$, and the particle
lifetime in the reaction-zones, $\tau(t)$. Mixed morphology systems are
essentially one large reaction zone, with $L \sim l_{AB} \sim l_{AA}$. By
relating these quantities through the scaling behavior of particle fluxes and
microscopic annihilation rates within reaction-zones, we determine the
characteristic time-exponents of these quantities at late times. The morphology
of the system, segregated or mixed, is also determined self-consistently. With
this unified approach, we consider systems with diffusion and/or long-range
interactions, and with either uncorrelated or correlated high-temperature
initial conditions. Finally, we discuss systems with particle-like topological
defects and electronic systems in various substrate dimensions --- including
quantum-hall devices with skyrmions.
