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…
Exciton band topology in spontaneous quantum anomalous Hall insulators: applications to twisted bilayer graphene
Yves H. Kwan, Yichen Hu, Steven H. Simon +1
We uncover topological features of neutral particle-hole pair excitations of correlated quantum anomalous Hall (QAH) insulators whose approximately flat conduction and valence band…
Coupled Wire Model of Orbifold Quantum Hall States
Pok Man Tam, Yichen Hu, Charles L. Kane
We construct a coupled wire model for a sequence of non-Abelian quantum Hall states occurring at filling factors with integers and even(odd) integers for fermi…
Galois Symmetry Induced by Hecke Relations in Rational Conformal Field Theory and Associated Modular Tensor Categories
Jeffrey A. Harvey, Yichen Hu, Yuxiao Wu
Hecke operators relate characters of rational conformal field theories (RCFTs) with different central charges, and extend the previously studied Galois symmetry of modular represen…
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…
Aspects of Defect Topology in Smectic Liquid Crystals
Thomas Machon, Hillel Aharoni, Yichen Hu +1
We study the topology of smectic defects in two and three dimensions. We give a topological classification of smectic point defects and disclination lines in three dimensions. In a…
