Fermi surface and Berry phase analysis for Dirac nodal line semimetals: cautionary tale to SrGa $_{2}$ and BaGa $_{2}$

Yuxiang Gao, Yichen Zhang, Shiming Lei +8

A Berry phase of odd multiples of $π$ inferred from quantum oscillations (QOs) has often been treated as evidence for nontrivial reciprocal space topology. However, disentangling t…

Topological Surface State Evolution in Bi $_{2}$ Se $_{3}$ via Surface Etching

Ziqin Yue, Jianwei Huang, Ruohan Wang +10

Topological insulators are materials with an insulating bulk interior while maintaining gapless boundary states against back scattering. Bi $_{2}$ Se $_{3}$ is a prototypical topological…
