Condensed matter physics leads to a "first-principles" way of looking at crystals, enabling physicists and mineralogists to study the rich and sometimes unexpected behavior that minerals exhibit under the extreme conditions within the earth. This volume fully details the exciting interaction between geophysics and condensed matter physics. Leading international researchers from both geosciences and condensed matter physics detail this cutting edge, interdisciplinary field. The volume is an excellent summary for specialists and graduate students researching mineralogy and crystallography.
