The optical spectrum of a single quantum dot is strongly affected by coherent tunnelling to a nearby sea of electrons. A semiconductor quantum dot is a crystal so small that it forces an optically ...

Many-body interactions give rise to fascinating physics such as the X-ray Fermi-edge singularity in metals, the Kondo effect in the resistance of metals with magnetic impurities and the fractional ...

Rocket Lab had another productive fishing trip. One of the company's two-stage Electron rockets successfully launched two commercial Earth-observing satellites to orbit on Wednesday (Nov. 17) from ...
