Query: Hybridization-switching induced Mott transition in ABO$_3$ perovskites   We propose the concept of "hybridization-switching induced Mott transition"
which is relevant to a broad class of ABO$_3$ perovskite materials including
BiNiO$_3$ and PbCrO$_3$ which feature extended $6s$ orbitals on the A-site
cation (Bi or Pb), and A-O covalency induced ligand holes. Using {\it ab
initio} electronic structure and slave rotor theory calculations, we show that
such systems exhibit a breathing phonon driven A-site to oxygen
hybridization-wave instability which conspires with strong correlations on the
B-site transition metal ion (Ni or Cr) to induce a Mott insulator. These Mott
insulators with active A-site orbitals are shown to undergo a pressure induced
insulator to metal transition accompanied by a colossal volume collapse due to
ligand hybridization switching.
