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…
Verification and Validation of zero-point electron-phonon renormalization of the bandgap, mass enhancement, and spectral functions
Samuel Poncé, Jae-Mo Lihm, Cheol-Hwan Park
Verification and validation of methods and first-principles software are at the core of computational solid-state physics but are too rarely addressed. We compare four first-princi…
Self-consistent electron lifetimes for electron-phonon scattering
Jae-Mo Lihm, Samuel Poncé, Cheol-Hwan Park
Acoustic phonons in piezoelectric materials strongly couple to electrons through a macroscopic electric field. We show that this coupling leads to a momentum-dependent divergence o…
Plasmon-Phonon Hybridization in Doped Semiconductors from First Principles
Jae-Mo Lihm, Cheol-Hwan Park
Although plasmons and phonons are the collective excitations that govern the low-energy physics of doped semiconductors, their nonadiabatic hybridization and mutual screening have…
