Physics:Quantum materials/topological phase
From HandWiki Test
A topological phase is a phase of matter characterized by global structural properties that remain unchanged under continuous deformations.
Topological materials exhibit robust edge states determined by global properties.
Description
Unlike conventional phases, which are defined by local order (such as crystal structure), topological phases are defined by global features of the system. These features are robust against local disturbances.
Topological phases can give rise to special states at the boundaries of materials, which remain stable even in the presence of imperfections.
Properties
- defined by global structure
- robust against perturbations
- not characterized by local order
- linked to symmetry
