Revisiting quantum effects on dislocation glide in bcc metals from DFT calculations and machine-learning potentials

Quantum zero-point effects have been long proposed to explain a well-known discrepancy between the low-temperature flow stresses of body-centered cubic metals and corresponding atomistic models of plastic flow. Previous investigations on quantum effects relied on empirical intera...

Development of ultrafast and radiation-hard GAGG for the next-generation of High-Energy Physics calorimeters

The evolution of High Energy Physics (HEP) toward future collider experiments with High Luminosity (HL), such as the HL-LHC, requires the development of scintillating materials that combine high density, excellent radiation hardness and an ultrafast response. While Cerium-doped G...

Tailoring attosecond charge migration in native molecular ions

Attosecond chemistry involves developing strategies to manipulate electronic coherent waves in molecules, which can influence the outcome of photoinduced reactions. While recent progress in this field calls for investigations of increasingly complex isolated or embedded systems,...

Surface Plasmons in the Continuum

Abstract The interest to foster plasmonic applications at energies in the ultraviolet has escalated research initiatives in clusters of unconventional plasmonic materials like aluminum and indium, for which the surface-plasmon resonance appears above the ionization potential. Nat...
