Quantum Spin-1/2 Rings Built from [2]Triangulene Molecular Units
Can Li, Manish Kumar, Ying Wang +14
Quantum spin rings represent fundamental model systems that exhibit distinctive quantum phenomena-such as quantum critical behavior and quasiparticle excitations-arising from their…
Interplay of Quantum Size Effect and Tensile Strain on Surface Morphology of Sn(100) Islands
Bing Xia, Xiaoyin Li, Hongyuan Chen +16
The quantum size effect (QSE) and strain effect are two key factors influencing the surface morphology of thin films, which can increase film surface roughness through QSE-induced…
Fabrication and Characterization of the Moiré surface state on a topological insulator
Yi Zhang, Dang Liu, Qiaoyan Yu +19
A Moire superlattice on the topological insulator surface is predicted to exhibit many novel properties but has not been experimentally realized. Here, we developed a two-step grow…
Topological surface state dominated nonlinear transverse response and microwave rectification at room temperature

Atomic-Scale Imaging of Fractional Spinon Quasiparticles in Open-Shell Triangulene Spin- Chains
Zhangyu Yuan, Xin-Yu Zhang, Yashi Jiang +14
The emergence of spinon quasiparticles, which carry spin but lack charge, is a hallmark of collective quantum phenomena in low-dimensional quantum spin systems. While the existence…
Observation of magnetism induced topological edge state in antiferromagnetic topological insulator MnBi4Te7
HaoKe Xu, Mingqiang Gu, Fucong Fei +16
Breaking time reversal symmetry in a topological insulator may lead to quantum anomalous Hall effect and axion insulator phase. MnBi4Te7 is a recently discovered antiferromagnetic…
Inherited Weak Topological Insulator Signatures in Topological Hourglass Semimetal Nb3XTe6 (X = Si, Ge)
