Some phases of matter cannot be described using the conventional framework of symmetry breaking and exhibit a so-called quantum order. One type of quantum order, known as topological order, is ...

Physicists have observed a novel quantum effect termed "hybrid topology" in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and ...

In a quiet corner of low-temperature physics, researchers have stumbled on a phase of matter that seems to break one of the field’s unwritten rules: it works without well-defined particles. Instead of ...

Topological superconductors are materials that, beyond simply exhibiting superconductivity, possess a topological order. This order refers to the global properties of the material's wavefunctions that ...

FIG.1. (a) Schematic representation of the third generation of the Sierpinski gasket waveguide arrays with r=0.3a, 0.5a, 0.6a. Blue and orange sectors of these arrays represent the first and ...

Artistic illustration of a topological exciton insulator: Excitons condense in the bulk of the material, forming a collective insulating phase, while topologically protected edge modes propagate ...

Researchers from the University of Hong Kong studying the structure of electrons in 2D materials have predicted new types of phase transitions that have yet to be seen in experiments Illustration of ...
