Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

open access: yesNano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen

open access: yesPhysik in unserer Zeit, EarlyView.
Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.
