The authors of a paper in Nature Photonics have been forced to walk back their article after learning from another group of researchers that their conclusions likely were an, ahem, optical illusion.
The paper, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” appeared in January 2012 and came from a team led by that included Aaron Danner, an optics expert at the National University of Singapore. As the abstract of the paper explains (to physicists, anyway):
