  We study the lattice dynamics of antiferromagnetic transition-metal oxides by
using self-consistent Hubbard functionals. We calculate the ground states of
the oxides with the on-site and intersite Hubbard interactions determined
self-consistently within the framework of density functional theory. The
on-site and intersite Hubbard terms fix the errors associated with the electron
self-interaction in the local and semilocal functionals. Inclusion of the
intersite Hubbard terms in addition to the on-site Hubbard terms produces
accurate phonon dispersion of the transition-metal oxides. Calculated Born
effective charges and high-frequency dielectric constants are in good agreement
with experiment. Our study provides a computationally inexpensive and accurate
set of first-principles calculations for strongly-correlated materials and
related phenomena.
