Topological insulators (TIs) are a class of materials with surfaces that host a new quantum state of matter and are insensitive to contaminants, defects and impurities. Surface electrons in TIs behave ...

Gapless states are thus bound to the interface. The surface of a crystal can be viewed as an interface with the vacuum, which, like a conventional insulator, is in the trivial topological class.

Topological insulators are materials that are insulating ... of whether time is flowing backward or forward. These surface states are robust, maintained even in the presence of surface defects.

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their ...

Specifically, the linear dispersion around Dirac points underpins the formation of robust surface states in topological insulators and contributes to the exotic electronic properties of topological ...

thereby collapsing the quantum state. In topological insulators, in particular, these higher temperatures create a situation in which the electrons on the surface of the insulator invade the ...

Quantum theory restricts certain physical quantities to specific values, influencing material behavior, particularly in ...

The discovery of a dual topological insulator introduces a new method for creating topological flat minibands through electron interactions, which offer a promising platform for exploring exotic ...

A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now ...
