Resistivity in the Spin-Gap State of the t-J Model
Resistivity in the Spin-Gap State of the t-J Model
Being motivated by recent experimental data on YBaCuO, we calculate dc resistivity in the spin-gap state of charge- spin-separated t-J model by using a massive gauge theory of holons and spinons.The result shows it deviates downward from the T-linear behavior below the spin-gap onset temperature.
