Looking for better ways to power electronics, topological semimetals may hold the answer.

Across disciplines, exciting stuff happens along the boundaries between things. What makes those realms so rich for research, and how do magnets shed light on them?

This area of research could help scientists understand high-temperature superconductivity and other mysteries.

The work gives physicists a new tool for exploring and understanding a class of materials that could lead to faster electronics.

At the National MagLab, scientists have been experimenting for years on materials first dreamed up by the newest physics Nobel laureates decades ago.

New research published this week in Nature Physics explores a material that could play a key role in realizing spin-based electronics.

Discovering previously unobserved quantum states nested inside the quantum Hall effect in a single-layer form of carbon known as graphene, researchers have found evidence of a new state of matter that challenges scientists' understanding of collective electron behavior.

New kind of quantum Hall state observed in graphene superlattices.

A topological insulator is a time reversal symmetry preserving material with a non-trivial topological order, which behaves as an insulator in the bulk although its surface is conducting.

The work by Chen et. al. explores the quantum hall effect (QHE) that develops in BiSbTeSe2 at low temperatures and high magnetic fields. BiSbTeSe2 is a topological insulator, meaning it is a bulk insulating material that at low temperatures develops a quantum mechanical state that allows conduction of electrons at the surface similar to a metal. The observation of the QHE in BiSbTeSe2 is further confirmation of the theory governing these unique materials.
