On Aug. 17, the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the fifth fingerprint of a massive disturbance in spacetime since LIGO began operations in September 2015. Unlike the first four sets of ...

Chiral superconductors are unconventional superconducting materials with distinctive topological properties, in which time-reversal symmetry is broken. Two of the first materials to be identified as chiral superconductors ...
Advanced materials with more novel properties are almost always developed by adding more elements to the list of ingredients. But quantum research suggests some simpler materials might already have advanced properties that ...
