Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface ...

Topological interlocking materials and structures represent an innovative design approach in which individual, often geometrically complex, elements are arranged to mutually constrain one another.

WEST LAFAYETTE, Ind. — The characteristics of a new, iron-containing type of material that is thought to have future applications in nanotechnology and spintronics have been determined at Purdue ...

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 ...

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 ...

Researchers have successfully simulated higher-order topological (HOT) lattices with unprecedented accuracy using digital quantum computers. These complex lattice structures can help us understand ...

Topological materials promise electronics that are faster, cooler, and far more robust, but until now they have mostly ...

In the natural world, many things come in mirror-image pairs. Your left and right hands are a perfect example—they look alike but can’t be perfectly superimposed. This idea, called chirality or ...

Recently, Prof. Andrea Alù from the City University of New York and Dr. Guangwei Hu from Nanyang Technological University in Singapore summarized previous representative work in the field of terahertz ...

One-dimensional surface hinge states characteristic of HOTIs. Researchers have shown how to detect HOTIs without observing such hinge states. Credit: The Grainger College of Engineering at University ...
