Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

Scientists observe unusual interference phenomena by scattering laser light from two atoms trapped inside an optical resonator. MPQ scientists observe unusual interference phenomena by scattering ...

Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...

This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...
