It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more ...

Discover 'ghostly' particles and quantum depletion. A new study makes the first observation of 'ghost particles' from Bose-Einstein condensates via 'quantum depletion': particles expelled by ...
