The hissing sound you hear in the background when you turn up the volume of your music player is called "noise". Most of this hiss is due to the thermal motion of electrons in the music-player circuitry. Just like molecules ...

A molecule of ammonia, NH3, typically exists as an umbrella shape, with three hydrogen atoms fanned out in a nonplanar arrangement around a central nitrogen atom. This umbrella structure is very stable and would normally ...

A team of researchers at the University of Toronto has found a way to measure how long quantum tunneling takes to happen. In their paper published in the journal Nature, the group describes experiments they conducted and ...
Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier. While quantum tunnelling is at the heart of the peculiar wave nature of particles, this ...

(PhysOrg.com) -- Detecting the coherent motion of a single electron is a challenge, for the simple reason of scale: the timescale of the coherent motion of a single-electron wave function is in the picosecond regime (one ...
(Phys.org)—In an attempt to solve some of the observational puzzles in physics, theorists have proposed a number of new physics models. Several of these models suggest the existence of extremely weakly interacting lightweight ...
Researchers at the University of Illinois at Chicago, in collaboration with their colleagues at the University of Hamburg in Germany, have imaged an exotic quantum particle—called a Majorana fermion—that can be used as ...
