Spin waves excited by hard x-ray transient gratings
Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49
Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…

Dichroism of coupled multipolar plasmonic modes in twisted triskelion stacks
Javier RodrÃguez-Ãlvarez, Joan Vila-Comamala, Antonio GarciÃa-MartÃn +9
We present a systematic investigation of the optical response to circularly polarized illumination in twisted stacked plasmonic nanostructures. The system consissts in two identica…
