Query: Microscopic theory on charge transports of a correlated multiorbital
  system   Current vertex correction (CVC), the back-flow-like correction to the
current, comes from conservation laws, and the CVC due to electron correlation
contains information about many-body effects. However, it has been little
understood how the CVC due to electron correlation affects the charge
transports of a correlated multiorbital system. To improve this situation, I
studied the inplane resistivity, $\rho_{ab}$, and the Hall coefficient in the
weak-field limit, $R_{\textrm{H}}$, in addition to the magnetic properties and
the electronic structure, for a $t_{2g}$-orbital Hubbard model on a square
lattice in a paramagnetic state away from or near an antiferromagnetic (AF)
quantum-critical point (QCP) in the fluctuation-exchange (FLEX) approximation
with the CVCs arising from the self-energy ($\Sigma$), the Maki-Thompson (MT)
irreducible four-point vertex function, and the main terms of the
Aslamasov-Larkin (AL) one. Then, I found three main results about the CVCs.
First, the main terms of the AL CVC does not qualitatively change the results
obtained in the FLEX approximation with the $\Sigma$ CVC and the MT CVC.
Second, $\rho_{ab}$ and $R_{\textrm{H}}$ near the AF QCP have high-temperature
region, governed mainly by the $\Sigma$ CVC, and low-temperature region,
governed mainly by the $\Sigma$ CVC and the MT CVC. Third, in case away from
the AF QCP, the MT CVC leads to a considerable effect on only $R_{\textrm{H}}$
at low temperatures, although $R_{\textrm{H}}$ at high temperatures and
$\rho_{ab}$ at all temperatures considered are sufficiently described by
including only the $\Sigma$ CVC. I also achieved the qualitative agreement with
several experiments of Sr$_{2}$RuO$_{4}$ or
Sr$_{2}$Ru$_{0.975}$Ti$_{0.025}$O$_{4}$. Moreover, I showed several better
points of this theory than other theories.
