Thermal diffuse scattering in TEM: complex absorptive potentials compared to the frozen phonon model
Martin Hájek, Ján Rusz
In transmission electron microscopy, electrons undergo inelastic scattering primarily through phonon excitations, known as thermal diffuse scattering. To capture the inelastic scat…
The beamformed trigger of RNO-G: its design and in-field performance
G Collaboration, S. Agarwal, J. A. Aguilar +76
The Radio Neutrino Observatory in Greenland (RNO-G) is a neutrino detector under construction at Summit Station, with 8 out of a planned 35 stations currently deployed. We have des…
ANDES, the high-resolution spectrograph for the ELT: design and performance analysis of the YJH spectrograph
Vinooja Thurairethinam, David Lee, James Stevenson +29
The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is a powerful second-generation high-resolution spectroscopic instrument for the Extremely Large Telescope (ELT). The UBV…
Archival Diagnostics for Potential Background Contaminantsof Project Hephaistos Dyson Sphere Candidates
Tongtian Ren, Michael A. Garrett, Erik Zackrisson +4
We report on the diagnostic investigation of nine Project Hephaistos Dyson Sphere candidate M-dwarfs based on archival data. By comparing the Gaia DR3 positions with epoch 2016.0,…
Combining Frozen Trajectory Excitation and TACAW for in silico Time-Resolved Vibrational Electron Energy Loss/Gain Spectroscopy
Wojciech Marciniak, Joanna Marciniak, José Ãngel Castellanos-Reyes +1
Seeing that ultrafast (picosecond timescale) vibrational electron energy loss spectroscopy (EELS) should soon be experimentally realizable, we present in silico approach capable of…
Itinerant Orbital Hall Effect Mechanism Leading to Large Negative Orbital Torques from Light Metal Vanadium
Nikhil Vijayan, Durgesh Kumar, Ao Du +13
The orbital Hall effect (OHE) has attracted significant attention for developing energy-efficient electronic devices. However, utilizing it in fast, low-power devices requires an e…
