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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
