Query: Transport anomalies near the QCD phase transition at finite density   We show that at finite density pressure-pressure and current-current
correlators exhibit divergences at $T_c$ owing to the fluctuations of the
diquark field. Specifically, this leads to a significant excess of the soft
photon production rate near $T_c$.
