We show that the spin-charge gauge approach to the 2D t-J model can naturally explain many experimental features of transport properties for High Tc cuprates, in particular temperature crossover phenomena in the “pseudogap phase” (PG) and 1/T behavior of conductivities in the “strange metal phase” (SM) at higher T or doping concentration. Furthermore, it is able to reproduce the universality and the quadratic in T behavior (above the crossover) of in-plane resistivity in PG. References: 1. P.A. Marchetti, Z.B. Su and L. Yu, Phys. Rev.
