Measuring Zak phase in room-temperature atoms

In topological insulators, global geometric phases of energy bands determine the existence of unidirectionally propagating edge states, which are immune to local defects, bringing a new stage for designing noise-resilient ...

Study makes spin liquid model more realistic

Spin is the intrinsic magnetic moment of a particle—an electron, for example. It is a fundamental magnitude, like mass and charge. Simply put, it is as if the particle had a magnet inside it that enabled it to interact, ...

Spiral dislocation gives 3D topological photonics a robust edge

Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based ...

The building blocks for exploring new exotic states of matter

Topological insulators act as electrical insulators on the inside but conduct electricity along their surfaces. Researchers study some of these insulators' exotic behavior using an external magnetic field to force the ion ...
