Topological Insulator Magnetic Tunnel Junctions: Quantum Hall Effect and Fractional Charge via Folding
Topological Insulator Magnetic Tunnel Junctions Quantum Hall Effect Fractional Charge Folding
2012/2/27
We provide a characterization of tunneling between coupled topological insulators in 2D and 3D under the influence of a ferromagnetic layer. We explore conditions for such systems to exhibit integer q...
Spin connection and boundary states in a topological insulator
Spin connection boundary states topological insulator
2010/12/24
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...
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...

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

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 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.
Observation of Magnetization dynamics and Interaction-induced Phases on Topological Insulator Surfaces

2010/10/27
Three dimensional topological insulators embody a newly discovered state of matter characterized by conducting spin-momentum locked surface states that span the bulk band gap [1–7]. This highly unusua...
