Exchange-Correlation Kernels Within Time-Dependent Density Functional Theory For Ground-State and Excited-State Properties
… approximation to assess its accuracy for dispersion interaction. Experimentally, CsF prefers the rocksalt (B1) phase, while the other halides CsCl, CsBr, and CsI prefer the cesium chloride (B2) phase. Without dispersion interaction, PBE and PBE0 predict all halides to prefer the B1 phase. …

Dynamic polarizability and collective modes in narrow-band electron systems
… particular by stiffening the frequency-momentum dispersion of surface plasmons and making it much stronger than that of the underlying narrow-band carriers. Strongly dispersing plasmons pierce through the particle-hole continuum and extend in the forbidden energy band above it. This behavior …

Growth and properties of metal-on-metal nanostructures: Ag on Cu(110) and Co on Ag(110)
… distinct quasi-1D structural anisotropy. The dispersion of Ag plasmons has been obtained and along the nanowire axis we find that the plasmon dispersion is linear with momentum transfer and remains constant beyond 0.3/Å. No dispersion is found for the plasmon perpendicular to the nanowire …
