We study bound states embedded into the continuum of edge states in two-dimensional
topological insulators. These states emerge in the presence of a short-range potential of a …

The results of a detailed study of the topological insulator Bi 2 Se 3 surface-state energy
structure in the vicinity of surface steps using scanning tunneling microscopy and …

Topological insulators (TIs) in the Bi 2 Se 3 family manifest helical Dirac surface states that
span the topologically ordered bulk band gap. Recent scanning tunneling microscopy …

SmB 6 has been predicted to be a Kondo topological insulator with topologically protected
conducting surface states. We have studied quantitatively the electrical transport through …

In an ideal topological insulator, the helical spin structure of surface electrons suppresses
backscattering and thus can enhance surface conductivity. In this study, we investigate the …

We present the study of the effect of both magnetic and potential scattering (M and U) of
magnetic impurities on the local electronic structures on a topological insulator. For single …

Topologically protected surface states of three‐dimensional topological insulators provide a
model framework for studying massless Dirac electrons in two dimensions. Usually a step on …

We use both continuum and lattice models to study the energy-momentum dispersion and
the dynamics of a wave packet for an electron moving in graphene in the presence of spin …

The discovery of topological quantum states of matter has required physicists to look beyond
Landau's theory of symmetry-breaking, previously the main paradigm for studying states of …

The topological insulator is a new type of quantum material with a non-trivial topological
order. They are characterized by conducting light-like surface states that stems from the non …
