Fluctuation effects of gauge fields in the slave-boson t-J model

TL;DR

This paper investigates the charge-spin separation in high-Tc superconductors using a U(1) gauge theory of the t-J model, focusing on the confinement-deconfinement transition and its critical temperature.

Contribution

It provides a quantitative analysis of the charge-spin separation phenomenon and determines the critical temperature for the confinement-deconfinement phase transition.

Findings

Charge-spin separation occurs below a specific critical temperature.

The critical temperature for the confinement-deconfinement transition is calculated.

The study advances understanding of gauge field effects in high-Tc superconductivity.

Abstract

We present a quantitative study of the charge-spin separation(CSS) phenomenon in a U(1) gauge theory of the t-J model of high-Tc superconductures. We calculate the critical temperature of confinement-deconfinement phase transition below which the CSS takes place.
