Ab initio self-consistent many-body theory of polarons at all couplings
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
We present a theoretical framework to describe polarons from first principles within a many-body Green's function formalism. Starting from a general electron-phonon Hamiltonian, we…
Unified approach to polarons and phonon-induced band structure renormalization
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
Ab initio calculations of the phonon-induced band structure renormalization are currently based on the perturbative Allen-Heine theory and its many-body generalizations. These appr…
Electron-phonon coupling of Fe-adatom electron states on MgO/Ag(100)
Haritz Garai-Marin, Julen Ibañez-Azpiroz, Peio Garcia-Goiricelaya +2
We study the strength of the electron-phonon interaction on Fe single adatoms on MgO/Ag(100) based on many-body \textit{ab-initio} spin collinear calculations. In particular, we an…
Symmetric Helmholtz Fermi-surface harmonics for an optimal representation of anisotropic quantities on the Fermi surface: Application to the electron-phonon problem
Jon Lafuente-Bartolome, Idoia G. Gurtubay, Asier Eiguren
We outline a numerical procedure to incorporate the crystal symmetries in the Helmholtz Fermi-surface harmonics basis set, which are the solutions of the Helmholtz equation defined…
Fully anisotropic superconductivity with few Helmholtz Fermi-surface harmonics
Jon Lafuente-Bartolome, Idoia G. Gurtubay, Asier Eiguren
We present an alternative representation for the anisotropic Eliashberg equations of superconductivity, whose numerical solution yields an efficiency gain of several orders of magn…
pygiftgenerator: A python module designed to prepare Moodle-based quizzes
Jon Sáenz, Idoia G Gurtubay, Zunbeltz Izaola +1
We present pygiftgenerator, a python module for systematically preparing a large number of numerical and multiple-choice questions for Moodle-based quizzes oriented to students' fo…
