A first: Spintronics made visible
It’s an important emerging field, spintronics; though it’s not too well known. It’s based on a quantum property of electrons – they spin. Some electrons spin ‘up,’ some spin ‘down’ and if you can get a...

Quantum dots do it: The dark pulse laser
Lasers come in many variations of light: Red, blue, infrared, ultraviolet and so on. Now there is a laser that produces non-light – the dark pulse laser. Developed by a joint project of the National...

Physics: A smaller proton, a big challenge
The proton is one of the fundamental components of the atom. For a long time scientists have believed it to be 0.8768 femtometers in size (a femtometer is one quadrillionth of a meter). Now, it looks...
View ArticleGraphene finds mass appeal
Thanks to the 2010 Nobel Prize for physics, graphene is a hot topic. That doesn’t mean it’s a household word. Graphene is not like pencil lead, which most people know is graphite. (That may hold for...

The MIM diode: Another challenger for the electronics crown
Sometimes good ideas in technology languish because of serious implementation hurdles. The MIM diode (Metal-Insulator-Metal) was one of those technologies. Note the past tense.Essentially, a diode...

Changing the frame of reference for quantum mechanics
Is there a relationship between the Heisenberg uncertainty principle and quantum nonlocality? Only a quantum physicist should know, or care.Wrong, at least in one way.Granted, quantum mechanics is a...

Super-photon: A Bose-Einstein condensate with practical potential
Illustrated super-photon….Credit: Jan Klaers, University of BonnIs it time to start investing in Bose-Einstein condensates? They’re not dew drops, of course. Anything with ‘Einstein’ in it has got to...

The robin flies with quantum coherence
The quantum coherent robin red-breast…….Credit: NWFSIn a sense most science and technology news is made up of tidbits, bits and pieces of research. Some of the tidbits are choice morsels, others are...

Two big steps forward for quantum teleportation
Few things will tie your cerebral lobes in a knot like quantum mechanics, and even then, fewer things are as astonishing as quantum teleportation – the “transmission” of quantum values (qubits) over a...
