(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," ...
(Phys.org)—Scientists have discovered an anomaly in the properties of ice at very cold temperatures near 20 K, which they believe can be explained by the quantum tunneling of multiple protons simultaneously. The finding ...
(Phys.org) —An independent research team with members affiliated with several universities in the U.S. and Switzerland has concluded that the D-Wave Two computer shows no signs of quantum speedup. They've written a paper ...
(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 ...
(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 ...
(PhysOrg.com) -- “The concept of matter waves is at the heart of quantum mechanics,” Oliver Morsch tells PhysOrg.com. “At the beginning of the last century, scientists discovered that solid particles could exhibit properties ...
Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed ...
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 ...
Once unimaginable, transistors consisting only of several-atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize ...

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 ...
