A Neutron Microscope Using a Nested Wolter-I Condenser and a Bank of Diffractive-Refractive Achromatic Objectives
Henning Friis Poulsen, Cæcilie Andersen, Nolan Ravinet +10
We propose a nested Wolter-I mirror design for a neutron condenser, which is based on established X-ray telescope technology. We demonstrate through simulations that it can increas…
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…
Soft x-rays with Orbital Angular Momentum for resonant scattering experiments at the SOLEIL synchrotron
Pietro Carrara, Franck Fortuna, Renaud Delaunay +15
The paper presents a comprehensive description of a new setup implemented and commissioned at the SEXTANTS beamline of the SOLEIL synchrotron for absorption and scattering experime…
Nanoscale Ultrafast Lattice Modulation with Hard X-ray Free Electron Laser
Haoyuan Li, Nan Wang, Leon Zhang +24
Understanding and controlling microscopic dynamics across spatial and temporal scales has driven major progress in science and technology over the past several decades. While ultra…
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…
