Low-temperature properties of an almost-localized Fermi liquid
J Spaek, M Kokowski, JM Honig - Physical Review B, 1989 - APS
We calculate the low-temperature corrections to the properties of an almost-localized Fermi
liquid in the normal phase caused by the temperature-dependent renormalization of the
quasiparticle bandwidth. Our approach provides a natural extension to finite temperatures of
the theory of correlated electron systems devised by Brinkman and Rice. Applications to (V
1− x Ti x) 2 O 3, heavy fermions, and liquid He 3 are briefly discussed. The importance of
intersite correlations is stressed and discussed in physical terms.
