Impact of the electron-electron correlation on phonon dispersions : failure of LDA and GGA functionals in graphene and graphite

M. Lazzeri, Claudio Attaccalite, L. Wirtz, Francesco Mauri

We compute electron-phonon coupling (EPC) of selected phonon modes in graphene and graphite using various ab-initio methods. The inclusion of non-local exchange-correlation effects within the GW approach strongly renormalizes the square EPC of the A′ 1 K mode by almost 80% with respect to density…

Magnon nanometric multiplexers in quasi-one-dimensional cluster chains

Housni Al-Wahsh, Bahram Djafari-Rouhani, L. Dobrzynski, Abdellatif Akjouj

We present a multiplexing device made of nanometric magnetic cluster chains and adsorbed clusters near the chains. We show that this nanosystem can transfer one magnon frequency from one chain to the other. With an appropriate choice of the geometrical or magnetic parameters of the structure, it is…

Enhanced directional optical transmission

L. Dobrzynski, Abdellatif Akjouj

The system presented here enables transmission of almost all the light intensities injected in four input channels into one output channel. It is conceived in the form of a metallic wire with one central hole and four other holes parallel to the central one. The incident light is injected in the…
