Our understanding of simple solids, is firmly grounded on the Fermi liquid concept and powerful computational techniques built around the density functional theory. These ideas form the basis of our "standard model" of solid state physics and have provided us with an accurate description of many materials of great technological significance.
The design, discovery, characterization and control of novel materials is perhaps the most important research area for humanity as it moves into the 21rst century. A myriad of societal problems concerning energy, clean water and air, and medicine all need to be solved by the discovery of new compounds with dramatically improved, or even new, properties.
