Magnetism meets topology on a superconductor's surface

Electrons in a solid occupy distinct energy bands separated by gaps. Energy band gaps are an electronic "no man's land," an energy range where no electrons are allowed. Now, scientists studying a compound containing iron, ...

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 ...

Quirky response to magnetism presents quantum physics mystery

The search is on to discover new states of matter, and possibly new ways of encoding, manipulating, and transporting information. One goal is to harness materials' quantum properties for communications that go beyond what's ...

A fresh twist in chiral topology

The concept of chirality is well-established in science: when an object cannot be superimposed on its mirror image, both the object and its mirror image are called chiral. In the drug industry, for instance, more than 50% ...
