We consider conditions for the existence of boundary modes in non-Hermitian systems with
edges of arbitrary codimension. Through a universal formulation of formation criteria for …

Spin-orbit coupled materials have attracted revived prominent research interest as of late,
especially due their connection with topological materials. A hallmark of this pursuit is …

We present a general methodology toward the systematic characterization of crystalline
topological insulating phases with time-reversal symmetry. In particular, taking the two …

We show that the local in-gap Green's function of a band insulator G 0 (ε, k∥, r⊥= 0), with
r⊥ the position perpendicular to a codimension-1 or codimension-2 impurity, reveals the …

The past years have seen rapid progress in the classification of topological materials. These
diagnostical methods are increasingly getting explored in the pertinent context of magnetic …

We report on a certain class of three-dimensional topological insulators and semimetals
protected by spinless PT symmetry, hosting an integer-valued bulk invariant. We show using …

We elucidate the general rule governing the response of dislocation lines in three-
dimensional topological band insulators. According to this Kbt rule, the lattice topology …

The study of topological band structures have sparked prominent research interest the past
decade, culminating in the recent formulation of rather prolific classification schemes that …

The Witten effect predicts that a magnetic monopole acquires a fractional electric charge
inside topological insulators. In this work, we give a microscopic description of this …

A universal feature of topological insulators is that they cannot be adiabatically connected to
an atomic limit, where individual lattice sites are completely decoupled. This property is …
