Trillionths of a second: Photon pairs compress an electron beam into short pulses
Physicists at the University of Konstanz have generated one of the shortest signals ever produced by humans: Using paired laser pulses, they succeeded in compressing a series of electron pulses to a numerically analyzed duration of only 0.00000000000.....»»
Developing innovative new display technologies to create ultrahigh-definition screens efficiently
A research team has developed a double-layer dry transfer printing technology that simultaneously transfers light-emitting and electron-transferring layers onto a substrate. This technology is expected to provide a more life-like view in augmented re.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes

Study uncovers condensed-matter dark states in a quantum system with two pairs of sublattices
Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system int.....»»
