Band structure effects on the Be(0001) acoustic-surface-plasmon energy dispersion

V. M. Silkin, J. M. Pitarke, E. V. Chulkov +8

We report first-principles calculations of acoustic surface plasmons on the (0001) surface of Be, as obtained in the random-phase approximation of many-body theory. The energy disp…

Classification of solvable Leibniz algebras with abelian nilradical and $k - 1$ dimensional extension

R. K. Gaybullaev, A. Kh. Khudoyberdiyev, K. Pohl

This work is devoted to the classification of solvable Leibniz algebras with an abelian nilradical. We consider $k - 1$ dimensional extension of $k$ -dimensional abelian algebras and…

Dark photon searches in the photon channel

D. Aristizabal Sierra, A. Betancur, K. Pohl +1

Spectral shape differences between photons produced in $I ¨ ^{0} \to I^^{3} + I^^{3}$ and $I ¨ ^{0} \to I^^{3} + A_{D}$ may provide a new avenue for dark photon searches. Assuming 70 $I^¼$ m thick tungsten foils…
