Pressure Induced Metal-Nonmetal and FCC-BCC Transitions in
The band structure of fcc and bcc calcium at different densities is obtained with the Augmented Plane Wave (APW) method using a soft-core approximation and Gaspar-Kohn-Sham potential. A tight-binding(TB) model is then built successfully to reproduce the first principles band structure and density of states. Properties examined within TB include bulk modulus, elastic constants, metal-nonmetal
