Bulk plasmons in elemental metals
Dario A. Leon, Claudia Cardoso, Kristian Berland
The spectral properties, momentum dispersion, and broadening of bulk plasmonic excitations of 26 elemental metals are studied from first principles calculations in the random-phase…
Common errors in BoltzTraP-based calculations
Øven A. Grimenes, Kristian Berland
Boltzmann transport calculations based on band structures computed from first principles play an important role in modern thermoelectric materials research. Among available codes,…
Self-consistent layer-projected scissors operator for band structures of complex 2D van der Waals materials
Dario A. Leon, Mikael Kuisma, Mikkel Ohm Sauer +6
We introduce a computationally efficient method to calculate the quasiparticle (QP) band structure of general van der Waals (vdW) heterostructures. A layer-projected scissors (LAPS…
Spectral properties from an efficient analytical representation of the self-energy within a multipole approximation
Dario A. Leon, Kristian Berland, Claudia Cardoso
We propose an efficient analytical representation of the frequency-dependent self-energy via a multipole approximation (MPA-). The multipole-Padé model for the self-ene…
