Switching Cause and Effect in Quantum World? A Causes B Causes A
October 2, 2012 — A deeply rooted concept in everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. Physicists have ... > full story -
Quantum Physics: First Images of Landau Levels Revealed
October 1, 2012 — Physicists have directly imaged Landau Levels – the quantum levels that determine electron behavior in a strong magnetic field – for the first time since they were theoretically conceived ... > full story -
Electrons Confined Inside Nano-Pyramids
September 28, 2012 — Quantum dots are nanostructures of semiconducting materials that behave a lot like single atoms and are very easy to produce. Given their special properties, researchers see huge potential for ... > full story -
Novel Materials Become Multifunctional at Ultimate Quantum Limit
September 25, 2012 — Physicists have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop ... > full story -
A Clock That Will Last Forever: Proposal to Build First Space-Time Crystal
September 24, 2012 — Imagine a clock that will keep perfect time forever or a device that opens new dimensions into the study of quantum phenomena such as emergence and entanglement. Researchers have proposed a ... > full story -
Squeeze Light 'Till It Hurts' on a Quantum Scale: Researchers Push the Boundaries on Ultra-Precise Measurement
September 21, 2012 — Physicists has pushed the boundaries on ultra-precise measurement by harnessing quantum light waves in a new way. It is one thing to be able to measure spectacularly small distances using "squeezed" ... > full story -
