Now that those pesky, annoying trolls have been flushed. oh, better be careful since my SO is of Scandanavian descent, and just loves the little buggers.. We can get back to the fun stuff!
New class of electron interactions in quantum systems http://www.physorg.com/news/2012-01-class-electron-interactions-quantum.html and these two statements smacked me upside the head. "Importantly, by applying a strong magnetic field, the researchers were able to tune this effect to eliminate the spin-spin interactions while preserving the orbital-orbital interactions. "By tuning the effect in two different symmetries of the fundamental state of the system.we have observed a symmetry crossover identical to those seen in high-energy physics," says Tettamanzi. This is kind of interesting as well. but note the wording 'apparent violation', "The idea here is to create a current flowing through a nanostructure without applying a voltage between the leads, but by applying varying potentials at one or more gates of the transistor, in an apparent violation of Ohm's law." More information: The paper will be published this week in Physical Review Letters (online on January 26), but can be viewed online now at arXiv: http://arxiv.org/abs/1102.2977 -Mark
