The strong correlation effects on topological insulator are studied in a two-sublattice system with an onsite single-particle energy difference between two sublattices. At = 0, increasing the onsi...
Large bulk resistivity and surface quantum oscillations in the topological insulator Bi2Te2Se
Large bulk resistivity surface quantum oscillations

Topological insulators are predicted to present novel surface transport phenomena, but their
experimental studies have been hindered by a metallic bulk conduction that overwhelms the surface transpor...
Helical Edge Modes near Transition to Topological Insulator with Indirect Gap
topological insulator edge mode indirect gap particle-hole symmetry semimetal annihilator

Helical edge modes are characteristic of topological insulators in two dimensions. This paper
demonstrates that helical edge modes remain across transitions to ordinary insulators or to semimetals un...

We study the surface resistivity of a three-dimensional topological insulator when the boundaries exhibit a non trivial curvature. We obtain an analytical solution for a spherical topological insulato...

We analyze theoretically the bound state spectrum of an Aharonov Bohm (AB) ring in a twodimensional topological insulator using the four-band model of HgTe-quantum wells as a concrete example.
