Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...
