Rice physicists show that quantum methods can predict nanophotonic behavior
According to new research from Rice University, scientists studying the way light interacts with metallic nanostructures should throw out their old optics textbooks and bone up on their quantum mechanics instead.
The new findings, which are described in the Oct. 17 issue of the journal Science, offer a new understanding of plasmonics, an emerging field of optics aimed at the study of light at the nanometer scale -- at dimensions far smaller than a wavelength of light, smaller than todays smallest electronic devices. Rices findings will make it easier for scientists and engineers to design new optical materials and devices "from the bottom up," using metal particles of specifically tailored shapes.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
