topological insulator

New research seems to show that it may be a topological insulator.

He is known for his work on semiconductor structures and topological insulators.

Some one put a picture of topological insulator (which has no topological order) in this page.

So we have to clarify that topological insulator is not an example of topological order.

A term analogous to the one that must be added to Maxwell's equations also appears in recent theoretical models for topological insulators.

Kane is notable for theoretically predicting the quantum spin Hall effect and what would later be known as topological insulators.

A 3D "strong topological insulator" exists which cannot be reduced to multiple copies of the quantum spin Hall state.

Topological insulator is an example another kind of order called SPT order.

SPT order generalizes the notion of topological insulator to interacting systems.

A topological insulator is a material that behaves as an insulator in its interior but whose surface contains conducting states.

On the surface of a topological insulator there are special states that fall within the bulk energy gap and allow surface metallic conduction.

(Note that Majorana zero-mode can also appear without 3D topological insulators.)

In contrast, topological insulators are robust only against perturbations that respect time-reversal and U(1) symmetries.

Topological insulator and quantum spin Hall state are different symmetry protected topological states.)

Recently it was shown both theoretically and experimentally, that mercury-telluride quantum well shows a unique new state of matter-the "topological insulator".

In fact, a topological insulator is a SPT state protected by particle number conservation and time reversal symmetry.

The first experimentally realized 3D topological insulator state (topological surface states) was discovered in bismuth antimonide.

(In fact, the proposed quantum wells do not exhibit the quantum spin Hall effect and should be regarded as topological insulators.)

In 2012 several groups released preprints which suggest that Samarium hexaboride has the properties of a topological insulator in accordance with the earlier theoretical predictions.

The non-trivialness of topological insulators is encoded in the existence of a gas of helical Dirac fermions.

In condensed matter physics K-theory has been used to classify topological insulators, superconductors and stable Fermi surfaces.

Non-interacting topological insulators are characterized by an index (known as Z topological invariants) similar to the genus in topology.

Helical Dirac fermion, which behaves like a massless relativistic particle, has been observed in a 3D topological insulator.

The boundary states of topological insulators play a key role in the detection and the application of topological insulators.

He is a condensed matter theorist known for his work on topological insulators, quantum spin Hall effect, spintronics, quantum Hall effect and high temperature superconductivity.
