Physicists solve quantum tunneling mystery

An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.

Evidence of macroscopic quantum tunneling detected in nanowires

A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" ...

Scientists create new recipe for single-atom transistors

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 ...

Chemists observe 'spooky' quantum tunneling

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 ...

Exerting better control over matter waves

(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 ...

The quantum secret to alcohol reactions in space

Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
