Frustration from Localized Zhang-Rice States: A Unified Theory of Doping-Driven Magnetic Transitions in Cuprates
Xiaodong Wang, Ping Xu, Jiong Mei +5
The microscopic mechanism by which doped holes disrupt the antiferromagnetic order is one of the fundamental questions in cuprates. In this work, we propose a unified microscopic t…

On the correlation between entanglement and the negative sign problem
Ping Xu, Yang Shen, Yuan-Yao He +1
In this work, we study the correlation between entanglement and the negative sign problem in quantum Monte Carlo for the simulation of low-dimensional strongly correlated quantum m…

Magnetic electron-hole asymmetry in cuprates: a computational revisit
Jiong Mei, Shao-Hang Shi, Ping Xu +5
In this work, we revisit the electron-hole asymmetry of antiferromagnetism in cuprates by studying the three-band Emery model. Using parameters relevant to LaCuO, we benchm…
