A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared to move faster than light itself, darting through a wave field before ...
Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...
A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By ...
