Splashing transients of 2D plasmons launched by swift electrons

Friday March 3rd, 2017 Hrvoje Buljan 0

Launching of plasmons by swift electrons has long been used in electron energy–loss spectroscopy (EELS) to investigate the plasmonic properties of ultrathin, or two-dimensional (2D), electron systems. However, the question of how a swift electron generates plasmons in space and time has never been answered. We address this issue by […]

Ab initio study of electronic excitations and the dielectric function in molybdenum disulfide monolayer

Monday November 14th, 2016 leo 0

The propagator of the induced dynamically screened Coulomb interaction is calculated for the monolayer. The energy-loss rate of a point charge placed near the monolayer is calculated (using the spatial resolution of the in the direction perpendicular to the plane) and successfully compared with very recent electron-energy-loss spectroscopy measurements of […]

Spin-orbit interaction in relativistic nuclear structure models

Monday September 26th, 2016 Ivan Balog 0

ABSTRACT: Relativistic self-consistent mean-field (SCMF) models naturally account for the coupling of the nucleon spin to its orbital motion, whereas nonrelativistic SCMF methods necessitate a phenomenological ansatz for the effective spin-orbit potential. Recent experimental studies aim to explore the isospin properties of the effective spin-orbit interaction in nuclei. SCMF models […]
