The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

3D plot of a single photon showing wave-like behaviour An international team of researchers has, for the first time, mapped complete trajectories of single photons in Young’s famous double-slit ...

Light sometimes prefers to take the scenic route. Now, a new twist on a classic experiment could trace photons’ wandering ways. In the Sept. 19 Physical Review Letters, researchers propose a version ...

An international research team led by physicists from Collaborative Research Centre 1238, 'Control and Dynamics of Quantum Materials' at the University of Cologne has implemented a new variant of the ...

New research demonstrates that particles move similar to billiard balls rolling along a table. Instead of the “realistic” path that you’re probably imagining though, the particles actually move in a ...

An international research group has developed a new X-ray spectroscopy method based on the classical double-slit experiment to gain new insights into the physical properties of solids. An ...
