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…
Nonlinear Hall effect from long-lived valley-polarizing relaxons
Jae-Mo Lihm, Cheol-Hwan Park
The nonlinear Hall effect has attracted much attention due to the famous, widely adopted interpretation in terms of the Berry curvature dipole in momentum space. Using ab initio Bo…
