source：natureAbstractQuasicrystals (QCs) possess a unique lattice structure without translational invariance, which is characterized by the rotational symmetry forbidden in periodic crystals such as the 5-fold rotation. Recent discovery of the ferromagnetic (FM) long-range order in the terbium-based QC has brought about breakthrough but the magnetic structure and dynamics remain unresolved. Here, we reveal the dynamical as well as static structure of the FM hedgehog state in the icosahedral QC. The FM hedgehog is shown to be characterized by the triple-Q state in the reciprocal-lattice qq spac...

source：techbriefsLaser crystals can be considered the “engines” of solid-state lasers. They are used for gain media, for frequency conversion, and to manage laser characteristics and performance. Like the engine of a car, if laser crystals are clean and working properly, they allow the larger system to operate at a higher level. In the case of a laser system, operating at a high level means creating a stable beam and reaching high optical powers. Some advantages of laser crystals over other solid-state gain media are that they typically offer less absorption, a narrower emission bandwidth, hig...
