Electron-phonon coupling in magnetic materials using the local spin density approximation
Á. A. Carrasco Álvarez, Ã. A. Carrasco Ãlvarez, M. Giantomassi +6
Magnetic materials are crucial for manipulating electron spin and magnetic fields, enabling applications in data storage, spintronics, charge transport, and energy conversion, whil…
Accurate calculation of Wannier centers, position matrix, and composite operators using translationally equivariant and higher-order finite differences
Jae-Mo Lihm, Minsu Ghim, Seung-Ju Hong +1
The momentum-space derivatives of Bloch wavefunctions are essential for studying quantum geometry and the equilibrium and response properties of solids. In practical first-principl…
Beyond-quasiparticle transport with vertex correction: self-consistent ladder formalism for electron-phonon interactions
Jae-Mo Lihm, Samuel Poncé
We present a self-consistent many-body framework for computing phonon-limited electronic transport from first principles, incorporating both beyond-quasiparticle effects and vertex…
The finite-difference parquet method: Enhanced electron-paramagnon scattering opens a pseudogap
Jae-Mo Lihm, Dominik Kiese, Seung-Sup B. Lee +1
We present the finite-difference parquet method that greatly improves the applicability and accuracy of two-particle correlation approaches to interacting electron systems. This me…
Phonon-limited carrier transport in the Weyl semimetal TaAs
Zhe Liu, Shashi B. Mishra, Jae-Mo Lihm +2
Topological Weyl semimetals represent a novel class of quantum materials that exhibit remarkable properties arising from their unique electronic structure. In this work, we employ…
Nonperturbative self-consistent electron-phonon spectral functions and transport
Jae-Mo Lihm, Samuel Poncé
Electron-phonon coupling often dominates the electron spectral functions and carrier transport properties. However, studies of this effect in real materials have largely relied on…
