Multiple Topological States in LaAgAs2, a Failed Square-Net Semimetal
Yang Liu, Tongrui Li, Xixi Yuan +15
The rational design of new materials emerges as an important direction to explore new topological materials, which is based on the understanding of the correlation between crystal…
Observation of spin-valley locked nodal lines in a quasi-2D altermagnet
Quanxin Hu, Xingkai Cheng, Qingchen Duan +19
The interplay among quantum degrees of freedom-spin, orbital and momentum-has emerged as a fertile ground for realizing magnetic quantum states with transformative potential for el…
Surface reconstruction and orthogonal decoupling in SrAl4 and EuAl4
Tongrui Li, Leiyuan Chen, Jian Yuan +10
Surface-induced symmetry breaking in quantum materials can stabilize exotic electronic phases distinct from those in the bulk, yet its momentum-space manifestations remain elusive…
Observation of floating surface state in obstructed atomic insulator candidate NiP
Xiang-Rui Liu, Ming-Yuan Zhu, Yuanwen Feng +15
Obstructed atomic insulator is recently proposed as an unconventional material, in which electric charge centers localized at sites away from the atoms. A half-filling surface stat…
