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% ...

Topological insulators (TIs) have an insulating interior and support conducting surface states with additional interfacing properties. The exotic metallic states on their surfaces can provide new routes to generate new phases ...
This it is the story of a unique material—made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups—two ...

The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions of electronic ...
