Holding pattern Small clusters of caesium atoms (pink blobs) were held in a vertical optical lattice. A laser then splits each atom into a quantum state in which half of the atom was closer to a ...

Matter-wave interferometry can be used to probe the foundations of physics and to enable precise measurements of particle properties and fundamental constants. It relies on beam splitters that ...

What is dark matter? Scientists from Britain and Germany say an as-yet-undetected subatomic particle could help account for the 80 percent of the universe's mass that we can't see. This theoretical ...

Left, schematics of the apparatus (positron beam, collimators, SiN gratings and emulsion detector. A HpGe detector is used as beam monitor). Right, single-particle interference visibility as a ...

Matter waves constitute a crucial feature of quantum mechanics, where particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated already in 1924 ...

Researchers from the Vienna University of Technology have performed the first separation of a particle from one of its properties. The study, carried out at the Institute Laue-Langevin (ILL) and ...

Dark energy -- a mysterious force pushing the universe apart at an ever-increasing rate -- was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle ...

Researchers at the University of Illinois Urbana-Champaign developed an instrument to measure the density of the dust that kicks up when spacecraft thrusters interact with planetary surfaces as it ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...

I always tell my students that LIGO (laser interferometer gravitational wave observatory) is one of humanity’s most stunning achievements. Basically, a group of people set out to measure the ...
