✦ Synopsis

Finite temperature transport quantities, as the optical conductivity a(w), the d.c. resistivity p(T), the Hall conductivity, are studied in the planar t -J model at various hole dopings using a novel method based on the Lanczos diagonalization of small systems. At optimum doping a(w) spectra show a slow non-Drude fall-off at large frequencies, while p(T) reveals a nearly linear T dependence, both results being in quantitative agreement with experiments on cuprates.
