Query: Pressure induced valence and metal-insulator transitions in the
  Falicov-Kimball model with nonlocal hybridization   We present a simple, but very realistic, model for a description of pressure
induced valence and metal-insulator transitions in mixed valence systems. It is
based on the extended Falicov-Kimball model and the supposition that the key
interaction governing these transitions is the nonlocal hybridization between
the localized $f$ and itinerant $d$ electrons. Taking into account, in
addition, the~parametrization between the external pressure and the $d$-$f$
hybridization (the experimental fact), the model is able to describe, at least
qualitatively, valence as well as metal-insulator transitions driven by the
external pressure observed experimentally in some rare-earth systems, like
SmB$_6$.
