Query: Memory matrix theory of the dc resistivity of a disordered
  antiferromagnetic metal with an effective composite operator   We perform the calculation of the dc resistivity as a function of temperature
of the "strange-metal" state that emerges in the vicinity of a
spin-density-wave phase transition in the presence of weak disorder. This
scenario is relevant to the phenomenology of many important correlated
materials, such as, e.g., the pnictides, the heavy-fermion compounds and the
cuprates. To accomplish this task, we implement the memory-matrix approach that
allows the calculation of the transport coefficients of the model beyond the
quasiparticle paradigm. Our computation is also inspired by the $\epsilon=3-d$
expansion in a hot-spot model embedded in $d$-space dimensions recently put
forth by Sur and Lee [Phys. Rev. B 91, 125136 (2015)], in which they find a new
low-energy non-Fermi liquid fixed point that is perturbatively accessible near
three dimensions. As a consequence, we are able to establish here the
temperature and doping dependence of the electrical resistivity at intermediate
temperatures of a two-dimensional disordered antiferromagnetic metallic model
with a composite operator that couples the order-parameter fluctuations to the
entire Fermi surface. We argue that our present theory provides a good basis in
order to unify the experimental transport data, e.g., in the cuprates and the
pnictide superconductors, within a wide range of doping regimes.
