TL;DR
This paper models the dc resistivity in the spin-gap state of the t-J model, revealing deviations from linear temperature dependence below the spin-gap onset, inspired by experimental data on YBaCuO.
Contribution
It introduces a massive gauge theory approach to calculate resistivity in the spin-gap state of the t-J model, providing new theoretical insights.
Findings
Resistivity deviates downward from T-linear behavior below the spin-gap onset.
The model aligns with experimental observations on YBaCuO.
Provides a theoretical framework for understanding spin-gap effects on resistivity.
Abstract
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.
