Fragile Topology is Unstable Under Translation Refinement
Yoonseok Hwang, Saavanth Velury, Taylor L. Hughes
Fragile topological phases become trivial upon the addition of suitable trivial bands, distinguishing them from stable topological phases. Nevertheless, various response phenomena…
Separate surface and bulk topological Anderson localization transitions in disordered axion insulators
Cormac Grindall, Alexander C. Tyner, Ang-Kun Wu +2
In topological phases of matter for which the bulk and boundary support distinct electronic gaps, there exists the possibility of decoupled mobility gaps in the presence of disorde…
Global and Local Topological Crystalline Markers for Rotation-Symmetric Insulators
Saavanth Velury, Yoonseok Hwang, Taylor L. Hughes
Crystalline symmetry can be used to predict bulk and surface properties of topological phases. For non-interacting cases, symmetry-eigenvalue analysis of Bloch states at high symme…
A mono-atomic orbital-based 1D topological crystalline insulator
Gengming Liu, Violet Workman, Jiho Noh +4
Topological crystalline insulators (TCIs) are classified by topological invariants defined with respect to the crystalline symmetries of their gapped bulk. The bulk-boundary corres…
