Beyond GGA: benefits from hybrid HSE06 functional for correct description of crystal and electronic structure and lattice dynamics of solids at ambient and elevated pressure

Selected cases will be presented of the superior performance of the HSE06 / PBEsol density functional calculations in reproduction of crystal and electronic structure as well as lattice dynamics of extended solids. Particular attention will be devoted to the cases when the ''industrial standard'' GGA-PBE calculations fail badly and provide misleading i.e. erroneous (qualitatively or quantitatively distorted) answers. The fascinating world of high pressure-driven phenomena, including the important issue of metallization of the chemical elements and compounds, will be addressed. Application of the HSE06/PBEsol tandem will then be extended to the seemingly well-established cases of polymorphism of the chemical elements, notably that of carbon. If time allows, selected aspects of the graphite-diamond transformation would be discussed.
