New advances using exotic matter may lead to ultrafast computing

In the 1960s, an exotic phase of matter known as an excitonic insulator was proposed. Decades later, evidence for this phase was found in real materials. Recently, particular attention has centered on Ta2NiSe5 because an ...

Electrons living on the edge

Scientists at the University of Tsukuba demonstrated the possibility of electrons moving as if they were massless when certain materials called "topological insulators" are irradiated with laser beams. This work may lead ...

The long-range transport of deconfined magnetic hedgehogs

Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies ...

Quantum insulators create multilane highways for electrons

New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect—where an electrical current does not lose energy as it flows along the edges of the material—over ...
