  As the experimental data from kaonic atoms and $K^{-}N$ scatterings imply
that the $K^{-}$-nucleon interaction is strongly attractive at saturation
density, there is a possibility to form $K^{-}$-nuclear bound states or kaonic
nuclei. In this work, we investigate the ground-state properties of the light
kaonic nuclei with the relativistic mean field theory. It is found that the
strong attraction between $K^{-}$ and nucleons reshapes the scalar and vector
meson fields, leading to the remarkable enhancement of the nuclear density in
the interior of light kaonic nuclei and the manifest shift of the
single-nucleon energy spectra and magic numbers therein. As a consequence, the
pseudospin symmetry is shown to be violated together with enlarged spin-orbit
splittings in these kaonic nuclei.
