Quantum transition makes electrons behave as if they lack spin

The common phase transitions are those that occur as a function of temperature variation. Ice changes phase to become liquid water at 0 degrees Celsius. Liquid water changes phase to become water vapor at 100 degrees Celsius. ...

A distinct spin on atomic transport

One of the more unexpected things that can be done with charge-neutral atoms is using them to emulate the fundamental behavior of electrons. Over the past few years, the group of Tilman Esslinger at the Institute of Quantum ...

A new way to measure gravity: Using floating atoms

A team of researchers at the University of California, Berkeley, has found a new way to measure gravity—by noting differences in atoms in a superposition state, suspended in the air by lasers. In their paper published in ...

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 ...

Evading Heisenberg isn't easy

EPFL researchers, with colleagues at the University of Cambridge and IBM Research-Zurich, unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements ...

Topological nanoelectronics

Topological insulators are materials with astonishing properties: Electric current flows only along their surfaces or edges, whereas the interior of the material behaves as an insulator. In 2007, Professor Laurens Molenkamp ...

New research finding gives valleytronics a boost

An international research team led by physicists at the University of California, Riverside, has revealed a new quantum process in valleytronics that can speed up the development of this fairly new technology.
