Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Among the first experiments at the National Synchrotron Light Source II--NSLS-II, a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Brookhaven National ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
