Magnetic Frustration and Spin-Charge Separation in 2D Strongly Correlated Electron Systems

Abstract

I propose that the ground state of the 2D $t$-$J$ model near half-filling with $J/t\sim 1/3$ has both ferromagnetic and antiferromagnetic fluctuations leading to a magnetically frustrated ground state. I further argue that the frustrated state is spin-charge separated to account for the observed behavior of the equal time spin and charge correlation functions.
