(Phys.org)—A team of researchers working in Singapore has come up with what they believe is a way to apply a topologic insulator to an object to prevent sound waves from being bounced back and detected by a source. They ...
The discovery of "topologically protected" electrical conductivity on the surface of some materials whose bulk interior acts as an insulator was among the most sensational advances in the last decade of condensed matter physics—with ...
