<blockquote>
A new cluster expansion (CE) is proposed to calculate band structure and
adiabatic potential of an insulator at high pressures. This kind of the CE is
developed to permit using Lovdin orthogonalization of atomic orbitals for
infinite crystals. The strong binding approach (LCAO method) and OPW one are
modified. The technique suggested also fits for the crystals having
impuirities, d-electrons, etc.
