Theory of transport phenomena in high-T-c cuprates

In this paper we point out that the anomalous transport phenomena in high-T -c cuprates are comprehensively understood on the basis of Fermi liquid the ory by taking account of a strong anti-ferromagnetic spin fluctuation. We a ssume phenomenologically the spectrum of magnetic excitation from experimen t and calculate the self-energy on the basis of the one loop approximation, We show that the T-linear term of damping rate, the momentum dependence of lifetime and the transformation of Fermi surface are important to explain the anomalous transport phenomena such as resistivity. Hall coefficient and c-axis resistivity. In particular, the strong spin fluctuation leads to th e transformation of Fermi surface which leads to a form more appropriate to nesting, This effect plays an important role. At last we show that our the ory is applicable to not only the normal state but also the pseudogap state .
