Multicellularity of delicate topological insulators
Aleksandra Nelson, Titus Neupert, Tomáš Bzdušek +1
Being Wannierizable is not the end of the story for topological insulators. We introduce a family of topological insulators that would be considered trivial in the paradigm set by…
From triple-point materials to multiband nodal links
Patrick M. Lenggenhager, Xiaoxiong Liu, Stepan S. Tsirkin +2
We study a class of topological materials which in their momentum-space band structure exhibit three-fold degeneracies known as triple points. Focusing specifically on $\mathcal{P}…
Exceptional Topological Insulators
M. Michael Denner, Anastasiia Skurativska, Frank Schindler +4
We introduce the exceptional topological insulator (ETI), a non-Hermitian topological state of matter that features exotic non-Hermitian surface states which can only exist within…
Geometric approach to fragile topology beyond symmetry indicators
Adrien Bouhon, Tomáš Bzdušek, Robert-Jan Slager
We present a framework to systematically address topological phases when finer partitionings of bands are taken into account, rather than only considering the two subspaces spanned…
