Finite-Temperature Techniques,bes how this state evolves with time. This suggests treating . as imaginary time, which has the advantage of enabling us to develop a perturbation theory for finite temperatures, a straightforward generalization of the perturbation treatment of the time evolution operator at . = 0.

Strongly Correlated Electrons,me holds true for La.CuO., a prototype for a class of materials with high superconducting transition temperatures (Sect. 14.2). CoO and La.CuO. are not metallic because the strong electron correlations suppress the charge fluctuations required for a nonvanishing conductivity. Instead they are insulators.

The theory has also been widely applied to molecules, thereby competing with standard quantum chemical methods, and to the computation of
