Optical and dc conductivities of cuprates: Spin fluctuation scattering in the t − J model

A microscopic theory of the electrical conductivity [sigma]( omega ) within the t - J model is developed. An exact representation for [sigma]( omega ) is obtained using the memory-function technique for the relaxation function in terms of the Hubbard operators, and the generalized Drude law is deriv...
