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 ...

When Feynman discussed the two-path interferometer in his famous lectures 1, he noted that quantum systems (quantons) display the behaviour of both waves and particles and that there is a sort of ...

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 ...

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 ...

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 ...

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 ...

What is an atom interferometer? Invented in 1991, atom interferometers take advantage of superposition, a fundamental principle in quantum mechanics that a particle can exist in multiple states ...

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 ...

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 ...
