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…
Anomalous open orbits in Hofstadter spectrum of Chern insulator
Haijiao Ji, Noah F. Q. Yuan, Hua Jiang +2
The nontrivial band topology can influence the Hofstadter spectrum. We investigate the Hofstadter spectrum for various models of Chern insulators under a rational flux $\frac{ϕ_{0}…
