Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or ...

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 ...

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 ...

Higher-order topological dynamics combines higher-order interactions, topology and non-linear dynamics giving rise to new emergent phenomena. These phenomena encode information which can dramatically ...

Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of ...

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This finding opens up a new range of possibilities for the development of efficient ...
