(Phys.org) —In a well-known quantum effect called superradiance, atoms can emit light at an enhanced rate compared to what is possible in classical situations. This high emission rate arises from the way that the atoms interact ...
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the first time this formation ...
Viewed macroscopically at room temperature, when water contacts other water, it will spread out and finally both mix together. In 2009, Chinese researchers first reported observing the formation of a liquid water droplet ...
Tom Broadhurst, an Ikerbasque researcher at the University of the Basque Country (UPV/EHU), has participated alongside scientists of the National Taiwan University in a piece of research that explores cold dark matter in ...
At TU Vienna, a new method was developed to utilize quantum mechanical vibrations for high precision measurements. The well-known concept of the Ramsey interferometer is applied to a complex multi particle system consisting ...
Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
(Phys.org) —Physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena. In a new proposed experiment in ...
(Phys.org) —When C. K. Hong, Z. Y. Ou and Leonard Mandel demonstrated destructive quantum interference between pairs of indistinguishable bosons in their 1987 paper1, they did so with massless photons. Their protocol – christened ...
(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass can ...
(Phys.org) —In an atom laser, millions of individual atoms propagate through space with minimal spreading, just like photons propagate in a coherent photon laser beam. Although both types of lasers are similar, atom lasers ...
