Eliashberg function unit
WebJan 15, 2024 · Using the Eliashberg spectral function computed in Ref. [3], the experimental value of T c can be found by setting μ tot ∗ = μ ∗ = 0.17. This value will be considered representative also for the hydrogenated diamond (111) surface. In the multi-band case, the values of μ jj ′ ∗ are determined by μ tot ∗ = 0.17 via Eq.

The plots depicted in Figs. 3 and 4 show the effects of hydrostatic pressure on phonon density of states and Eliashberg spectral function, respectively. As the plot in 3 clearly indicates, pressure suppresses the phonon density of states. ... WebOnce the Eliasberg function has been extracted from the photoemission data it can be used to calculate other quantities related to electron-boson coupling in these systems, such as …
Eliashberg's research interests are in differential topology, especially in symplectic and contact topology. In the 80's he developed a combinatorial technique which he used to prove that the group of symplectomorphisms is -closed in the diffeomorphism group. This fundamental result, proved in a different way also by Gromov is now called the Eliashberg-Gromov theorem, and is one of the fir… WebAug 24, 2024 · We elucidate the origin of the phonon-mediated superconductivity in 2H - NbS2 using the ab initio anisotropic Migdal-Eliashberg theory including Coulomb interactions. We demonstrate that superconductivity is associated with Fermi surface hot spots exhibiting an unusually strong electron-phonon interaction.
