We have developed a microscopic theory to describe these key transport features. The resistivity is calculated using the Kubo formula. The theory have successfully shown the linear T dependence of resistivity without the external magnetic field and explained as the external magnetic field increases, the resistivity gradually shows a low temperature metal-insulator upturns. Electronic Raman Response in Cuprate Superconductors. We investigate the ERS of hole-doped and electron-doped cuprate superconductors based on the t-t’-J model and fermion-spin theory. The temperature and doping dependence of the low energy ERS is calculated. We further study the evolution of electronic Raman response in external magnetic field. The results show the magnetic field suppresses the superconducting paring peak and electronic Raman spectrum weight.
