High Pressure Structural Phase Transitions in Solids presents theoretical high pressure activity from an ab initio electronic structure point-of-view. The book provides all available experimental and theoretical data, including unpublished theoretical data that shows how structural phase transitions take place at very high pressure as well as predicted phase transitions using theory under extreme conditions. This book will be appealing to a very broad audience, including those in condensed matter physics, materials science and geophysics. In addition, experimentalists, theorists, basic scientists, applied scientists, and scientists and technologists working at the interface of basic and applied science will find the content updated and refreshing.
