Query: Dynamical Screening Effect on Local Two-Particle Vertex Functions   In principle, the electronic Coulomb interaction among the correlated
orbitals is frequency-dependent. Though it is generally believed that the
dynamically screened interaction may play a crucial role in understanding the
subtle electronic structures of strongly correlated materials, hitherto we know
very little about it. In the Letter, we demonstrate that within the framework
of single-site dynamical mean-field theory the local two-particle Green's
functions $\chi$ and vertex functions $\Gamma$ are strongly modified by the
dynamically screened interaction. Since both $\chi$ and $\Gamma$ represent the
main ingredients to compute momentum-resolved response functions and to treat
non-local spatial correlations by means of diagrammatic extensions of dynamical
mean-field theory, it is urgent to reexamine previous results by taking the
dynamical screening effect into account. The modifications should be very
considerable.
