The quantum spin Hall effect and topological insulators
form many different states of matter, such as crystalline solids, magnets, and superconductors. Those different states can be classified by the symmetries they spontaneously break— translational, rotational, and gauge symmetries, respectively, for the examples above. Before 1980 all states of matter in condensed-matter systems could be classified by the principle of broken symmetry. The quantum...
متن کاملTopological Insulators a.k.a Quantum Spin Hall E ect
The recent experimental realization of a the quantum spin hall e ect has caused a lot of interest in these topological states of matter. Topological insulators are a new form of condensed matter that are not characterized by a spontaneously broken symmetry. Instead the materials are characterized by topology of the manifold of the occupied bloch states. Topological insulators have the unique pr...
متن کاملSelf-localized states in photonic topological insulators.
We propose solitons in a photonic topological insulator: self-localized wave packets forming topological edge states residing in the bulk of a nonlinear photonic topological insulator. These self-forming entities exhibit, despite being in the bulk, the property of unidirectional transport, similar to the transport their linear counterparts display on the edge of a topological insulator. In the ...
متن کاملCurrent correlations in quantum spin Hall insulators.
We consider a four-terminal setup of a two-dimensional topological insulator (quantum spin Hall insulator) with local tunneling between the upper and lower edges. The edge modes are modeled as helical Luttinger liquids and the electron-electron interactions are taken into account exactly. Using perturbation theory in the tunneling, we derive the cumulant generating function for the interedge cu...
متن کاملObservation of photonic anomalous Floquet topological insulators
Topological insulators are a new class of materials that exhibit robust and scatter-free transport along their edges - independently of the fine details of the system and of the edge - due to topological protection. To classify the topological character of two-dimensional systems without additional symmetries, one commonly uses Chern numbers, as their sum computed from all bands below a specifi...
