Spurious Strange Correlators in Symmetry-Protected Topological Phases
Wei-Liang Gao, Jie-Yu Zhang, Zheng-Xin Liu +1
Strange correlator is a powerful tool widely used in detecting symmetry-protected topological (SPT) phases. However, the result of strange correlator crucially relies on the adopti…

Deconfined Gapless phases and criticalities in Shastry-Sutherland Antiferromagnet
Lvcheng Chen, Zheng-Xin Liu
Antiferromagnets on the Shastry-Sutherland lattice have attracted lots of research interest due to the possible existence of deconfined criticality. In the present work, we study t…

Proposal of realizing the Sachdev-Ye-Kitaev model from a Kitaev Spin Chain
Han-yuan Zuo, Zheng-xin Liu
The Sachdev-Ye-Kitaev (SYK) model is zero-dimensional model simulating quantum chaos using interacting Majorana fermions.Previously proposals have been made to realize the SYK mode…
