Helical Symmetry Breaking and Quantum Anomaly in Massive Dirac Fermions
Huan-Wen Wang, Bo Fu, Shun-Qing Shen
Helical symmetry of massive Dirac fermions is broken explicitly in the presence of electric and magnetic fields. Here we present two equations for the divergence of helical and axi…

The Bulk-Hinge Correspondence and Three-Dimensional Quantum Anomalous Hall Effect in Second Order Topological Insulators
Bo Fu, Zi-Ang Hu, Shun-Qing Shen
The chiral hinge modes are the key feature of a second order topological insulator in three dimensions. Here we propose a quadrupole index in combination of a slab Chern number in…
