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…
Induced Zeeman effect of moiré surface states in topological insulators
Haijiao Ji, Noah F. Q. Yuan
Recently, moiré superlattices have been found on the surface of topological insulators due to the rotational misalignment of topmost layers. In this work, we study the effects of m…
Direct observation of quantum vortex fractionalization in multiband superconductors
Yu Zheng, Quanxin Hu, Haijiao Ji +13
Magnetic field is expelled from a superconductor, unless it forms quantum vortices, consisting of a core singularity with current circulating around it. The London quantization con…
Fractional vortices and Ising superconductivity in multiband superconductors
Haijiao Ji, Noah F. Q. Yuan
Inspired by the recent experiments in monolayer iron-based superconductors, we theoretically investigate properties of a two-dimensional multiband superconductor, focusing on two a…
Topological metal and high-order Dirac point in cubic Rashba model
Haijiao Ji, Ning Zhang, Noah F. Q. Yuan
We investigate the properties of the two-dimensional model with Rashba-type spin-orbit coupling cubic in electron momentum. In the normal phase, edge states emerge on open boundari…
