Projection of Infinite- Hubbard Model and Algebraic Sign Structure
Yunqing Ouyang, Xiao Yan Xu
We propose a projection approach to perform quantum Monte Carlo (QMC) simulation on the infinite- Hubbard model at some integer fillings where either it is sign problem free or…

Computing classification of interacting fermionic symmetry-protected topological phases using topological invariants
Yunqing Ouyang, Qing-Rui Wang, Zheng-Cheng Gu +1
In recent years, great success has been achieved on the classification of symmetry-protected topological (SPT) phases for interacting fermion systems by using generalized cohomolog…
