Query: Quantum Pressure Focusing in Solids: A Reconstruction from Experimental
  Electron Density   We present an approach for reconstructing the distribution of electronic
internal quantum pressure in the electronic continuum of solids from the
experimental electron density. Using the formalism of the density functional
theory, we obtain the spatial inner-crystal map of the quantum pressure. The
results are visualized via the indicator of quantum pressure focusing (IQPF)
which reveals the regions where the pressure is concentrated or depleted due to
the quantum effects. IQPF contains all quantum electron shell structure-forming
contributions resulting from kinetic, exchange and correlation effects, and
presents a clear picture of the chemical bond features in crystals with
different type of bonding mechanisms.
