Helmholtz Fermi surface harmonics: an efficient approach for treating anisotropic problems involving Fermi surface integrals
(IOP Publishing, 2014-06-09)
We present a new efficient numerical approach for representing anisotropic physical quantities and/or matrix elements defined on the Fermi surface (FS) of metallic materials. The method introduces a set of numerically ...
Magnetic Oscillations Induced by Phonons in Non-Magnetic Materials
(Nature, 2020-01-24)
The authors show that, similarly to electrons, in the presence of spin-orbit coupling, phonons can induce an effective magnetic oscillation even in non-magnetic materials, and therefore can act as an additional spin-flipping ...
Long-living carriers in a strong electron-phonon interacting two-dimensional doped semiconductor
(Nature Publishing Group, 2019-07-15)
Carrier doping by the electric field effect has emerged as an ideal route for monitoring many-body physics in two-dimensional materials where the Fermi level is tuned so that the strength of the interactions can also be ...
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
(IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ...
Fully anisotropic superconductivity with few Helmholtz Fermi-surface harmonics
(American Physical Society, 2020-10-09)
We present an alternative representation for the anisotropic Eliashberg equations of superconductivity, whose numerical solution yields an efficiency gain of several orders of magnitude with respect to the conventional ...
Coupled spin and electron-phonon interaction at the Tl/Si(111) surface from relativistic first-principles calculations
(American Physical Society, 2018-12-28)
We investigate the role played by the electron spin and the spin-orbit interaction in the exceptional electron-phonon coupling at the Tl/Si(111) surface. Our first-principles calculations demonstrate that the particular ...
