Surface State Magnetization and Chiral Edge States on Topological Insulators
Fan Zhang, C. L. Kane, E. J. Mele
We study the interaction between a ferromagnetically ordered medium and the surface states of a topological insulator with a general surface termination. This interaction is strong…
A new experimental approach for the exploration of topological quantum phenomena : Topological Insulators and Superconductors
M. Zahid Hasan, David Hsieh, Yuqi Xia +3
The three-dimensional topological insulator (originally called "topological insulators") is the first example in nature of a topologically ordered electronic phase existing in thre…
Interface Between Topological and Superconducting Qubits
Liang Jiang, Charles L. Kane, John Preskill
We propose and analyze an interface between a topological qubit and a superconducting flux qubit. In our scheme, the interaction between Majorana fermions in a topological insulato…
Observation of topologically protected Dirac spin-textures and πBerry's phase in pure Antimony (Sb) and topological insulator BiSb
D. Hsieh, Y. Xia, L. Wray +10
A topologically ordered material is characterized by a rare quantum organization of electrons that evades the conventional spontaneously broken symmetry based classification of con…
Surface States of the Topological Insulator Bi_{1-x}Sb_x
Jeffrey C. Y. Teo, Liang Fu, C. L. Kane
We study the electronic surface states of the semiconducting alloy BiSb. Using a phenomenological tight binding model we show that the Fermi surface of the 111 surface states enclo…
Superconducting proximity effect and Majorana fermions at the surface of a topological insulator
Liang Fu, C. L. Kane
We study the proximity effect between an s-wave superconductor and the surface states of a strong topological insulator. The resulting two dimensional state resembles a spinless p_…
