The development of plasmonic and metamaterial devices requires the research of high-
performance materials alternative to standard noble metals. Renewed as a refractory stable …

The local-field correction for the two-dimensional and the three-dimensional electron gas is
calculated within a sum-rule version of the self-consistent approach of Singwi, Tosi, Land …

Electron energy-loss experiments have shown a rapid softening of the bulk plasmon
dispersion across the series of the alkali metals. Motivated by these observations, we …

Plasmon, the collective oscillations of free electron gas in materials, determines the long-
wavelength excitation spectrum and optical response, are pivotal in the realm of …

We have measured plasmon energies in Na under high pressure up to 43 GPa using
inelastic x-ray scattering (IXS). The momentum-resolved results show clear deviations …

Within the random-phase approximation (RPA), we have obtained the average surface-
plasmon energy of voids and bubbles in nearly-free-electron metals using energy-weighted …

In the expanding field of plasmonics, accurate control of the degree of plasmon localization
is of crucial importance for tailoring optical properties at the nanoscale. In this paper, the …

Measured reflection electron energy loss spectra excited by 2 keV electrons in Si are
simulated by a Monte Carlo approach using the Chen–Kwei theory to calculate the position …

The plasmon dispersion relations in solid and liquid Rb were determined by inelastic x-ray
scattering techniques. In liquid Rb, the plasmon energy increases with the momentum …

A Bose‐Einstein Condensate (BEC) of a nonzero momentum Cooper pair constitutes a
composite boson or simply a boson. Previously, it has been shown that the quantum …
