We propose a feasible experimental scheme to realize a three-dimensional chiral topological insulator with cold fermionic atoms in an optical lattice, which is characterized by an integer topological ...
Protected by the chiral symmetry, three-dimensional chiral topological insulators are characterized by an integer-valued topological invariant. How this invariant could emerge in physical observables ...
We show that the surface states in topological insulators can be understood based on a well-known Shockley model, a one-dimensional tight-binding model with two atoms per elementary cell, connected vi...
Topological phases of matter are described universally by topological field theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg field theories. We propos...
We develop an Eliashberg theory for ferromagnetic quantum criticality in the surface of three dimensional topological insulators. A novel ingredient of the present study is to introduce an anomalous...
Topological phases of matter are described universally by topological eld theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg eld theories.We propose th...
The surface quantum Hall state, magneto-electric phenomena and their connection to axion electrodynamics have been studied intensively for topological insulators. One of the obstacles for observing su...
We study topological insulators characterized by the integer topological invariant Z, in even and odd spacial dimensions. These are well understood in case when there are no interactions. We extend th...
We lay out an experiment to realize time-reversal invariant topological insulators in alkali atomic gases. We introduce an original method to synthesize a gauge field in the near-field of an atom-chip...
We investigate electron interferometry of edge states in Topological Insulators. We show that, when inter-boundary coupling is induced at two quantum point contacts of a four terminal setup, both Fa...
We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low temperatures, the film ...
We study theoretically the RKKY interaction between magnetic impurities on the surface of threedimensional topological insulators, mediated by the helical Dirac electrons. Exact analytical expression ...
We propose the realization of topological quantum states with cold atoms trapped in an optical lattice. We discuss an experimental setup that generates a two-dimensional hexagonal lattice in the prese...
