Magnetic order and novel quantum criticality in the strongly interacting quasicrystals
Cong Zhang, Yin-Kai Yu, Shao-Hang Shi +1
We present the sign-problem-free quantum Monte Carlo study of the half-filled Hubbard model on two-dimensional quasicrystals, revealing how specific aperiodic geometries fundamenta…

Diagnosis of mixed-state topological phases in strongly correlated systems via disorder parameters
Shao-Hang Shi, Xiao-Qi Sun, Zi-Xiang Li
Characterizing topological phases for strongly interacting fermions in the mixed-state regime remains a major challenge. Here we introduce a general and numerically efficient frame…

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…
