Stability of highly-twisted Skyrmions from contact topology
Yichen Hu, Thomas Machon
We describe a topological protection mechanism for highly-twisted two-dimensional Skyrmions in systems with Dyloshinskii-Moriya (DM) coupling, where non-zero DM energy density (dub…

Higher angular momentum band inversions in two dimensions
Jörn W. F. Venderbos, Yichen Hu, C. L. Kane
We study a special class of topological phase transitions in two dimensions described by the inversion of bands with relative angular momentum higher than 1. A band inversion of th…
