ArticleKeys, Peter H.We use images of high spatial, spectral, and temporal resolution, obtained using both ground- and space-based instrumentation, to investigate the coupling between wave phenomena observed at numerous heights in the solar atmosphere. Analysis of 4170 � . . .
ArticleXing, D.Y.A high-speed silicon modulator with broad optical bandwidth is proposed based on a symmetrically configured Mach-Zehnder interferometer. Careful phase bias control and traveling-wave design are used to improve the high-speed performance. Over a broadb . . .
ArticleSheng, DonnaThe quantum spin Hall (QSH) effect is considered to be unstable to perturbations violating the time-reversal (TR) symmetry. We review some recent developments in the search of the QSH effect in the absence of the TR symmetry. The possibility to realiz . . .
