Generic Symmetry Breaking Instability of Topological Insulators due to a Novel van Hove Singularity
Xu-Gang He, Xiaoxiang Xi, Wei Ku
We point out that in the deep band-inverted state, topological insulators are generically vulnerable against symmetry breaking instability, due to a divergently large density of st…

Bulk Signatures of Pressure-Induced Band Inversion and Topological Phase Transitions in PbSnSe
Xiaoxiang Xi, Xu-Gang He, Fen Guan +10
The characteristics of topological insulators are manifested in both their surface and bulk properties, but the latter remain to be explored. Here we report bulk signatures of pres…
