Holes as Dipoles in a Doped Antiferromagnet and Stripe Instabilities
Su-Peng Kou, Zheng-Yu Weng
Based on an effective model of a doped antiferromagnetic Mott insulator, we show that a doped hole will induce a dipole-like spin configuration in a spin ordered phase at low dopin…

Topological Gauge Structure and Phase Diagram for Weakly Doped Antiferromagnets
Su-Peng Kou, Zheng-Yu Weng
We show that the topological gauge structure in the phase string theory of the {\rm t-J} model gives rise to a global phase diagram of antiferromagnetic (AF) and superconducting (S…
