摘要
It is generally believed that behaviours of quasiparticles (holes) in high-T-c cuprates should be attributed to the two-dimensional (2D) electronic states in the CuO2 planes. The various anomalies of the transport coefficients for temperatures above T-c are long-standing insoluble puzzles and cause serious controversy. Here we reanalyse the published experimental date of LSCO cuprates. We find that the normal-state susceptibility, resistivity, Hall coefficient, etc. vary precisely as T-2 In T as a function of temperature T in agreement with the prediction of the Fermi liquid model. The quasiparticles are shown to definitely behave as a 3D Fermi liquid. Various attempts to describe the system in terms of non-Fermi liquids, e.g. the RVB state, seems to be erroneous.
