Self-consistent scheme for optical response of large hybrid networks of semiconductor quantum dots and plasmonic metal nanoparticles
L. Hayati, C. Lane, B. Barbiellini +2
We discuss a self-consistent scheme for treating the optical response of large, hybrid networks of semiconducting quantum dots (SQDs) and plasmonic metallic nanoparticles (MNPs). O…
Explaining the x-ray nonlinear susceptibility of diamond and silicon near absorption edges
B. Barbiellini, Y. Joly, Kenji Tamasaku
We report the observation and the theoretical explanation of the parametric down-conversion nonlinear susceptibility at the -absorption edge of diamond and at the -absor…
Gradient correction scheme for bulk and defect positron states in materials: New developments
J. Kuriplach, B. Barbiellini
As local density approximation positron calculations systematically underestimate positron lifetimes when they are compared with their experimental counterparts, the generalized gr…
Inelastic X-ray scattering from valence electrons near absorption edges of FeTe and TiSe
B. Barbiellini, J. N. Hancock, C. Monney +4
We study resonant inelastic x-ray scattering (RIXS) peaks corresponding to low energy particle-hole excited states of metallic FeTe and semi-metallic TiSe for photon incident e…
Bulk Fermi surface and momentum density in heavily doped LaSrCuO using high resolution Compton scattering and positron annihilation spectroscopies
W. Al-Sawai, B. Barbiellini, Y. Sakurai +13
We have observed the bulk Fermi surface (FS) in an overdoped (=0.3) single crystal of LaSrCuO by using Compton scattering. A two-dimensional (2D) momentum densit…
Auger mediated quantum sticking of positrons to surfaces: Evidence for single step transition from a scattering state to a surface image potential bound state
S. Mukherjee, M. P. Nadesalingam, P. Guagliardo +5
We present the observation of an efficient mechanism for positron sticking to surfaces termed here Auger mediated quantum sticking. In this process the energy associated with the p…
