Solitons and real-space screening of bulk topology of quantum materials
Alexander C. Tyner, Pallab Goswami
Recent years have seen multiple high-throughput studies reveal an immense number of topological materials through use of symmetry indicators. Despite this success, three-dimensiona…

Part I: Staggered index and 3D winding number of Kramers-degenerate bands
Alexander C. Tyner, Pallab Goswami
For three-dimensional (3D) crystalline insulators, preserving space-inversion () and time-reversal () symmetries, the third homotopy class of two-fold, Kr…

Non-Abelian Stokes theorem and quantized Berry flux
Alexander C. Tyner, Shouvik Sur, Qunfei Zhou +4
Band topology of anomalous quantum Hall insulators can be precisely addressed by computing Chern numbers of constituent non-degenerate bands that describe quantized, Abelian Berry…
