First-principles study of KCoF: Jahn-Teller effect, dynamical magnetic charges, magnetoelectric multipoles and antimagnetoelectricity
Bogdan Guster, Maxime Braun, Eric Bousquet
We study from \textit{ab~initio} density functional theory calculations the structural and magnetic properties of the crystal KCoF. We found that the experimentally reported cu…
Large dynamical magnetic effective charges and anti-magnetoelectricity from spin and orbital origin in multiferroic BiCoO
Maxime Braun, Bogdan Guster, Andrea Urru +2
Using first-principles calculations, we explore the magnetoelectric properties of the room-temperature multiferroic crystal BiCoO. We use both applied magnetic field and finite…
High-throughput analysis of Fröhlich-type polaron models
Pedro Miguel M. C. de Melo, Joao C. de Abreu, Bogdan Guster +4
The electronic structure of condensed matter can be significantly affected by the electron-phonon interaction, leading to important phenomena such as electrical resistance, superco…
Competition between Ta-Ta and Te-Te bonding leading to the commensurate charge density wave in TaTe4
Bogdan Guster, Miguel Pruneda, Pablo Ordejón +1
The origin of the charge density wave in TaTe is discussed on the basis of a first-principles DFT analysis of the Fermi surface, electron-hole response function, phonon band st…
Fröhlich polaron effective mass and localization length in cubic materials: degenerate and anisotropic electronic bands
Bogdan Guster, Pedro Melo, Bradley A. A. Martin +7
Polarons, that is, charge carriers correlated with lattice deformations, are ubiquitous quasiparticles in semiconductors, and play an important role in electrical conductivity. To…
Electron-hole response function of transition metal trichalcogenides NbSe and monoclinic-TaS
Bogdan Guster, Miguel Pruneda, Pablo Ordejón +2
NbSe and monoclinic-TaS (-TaS) are quasi-1D metals containing three different types of chains and undergoing two different charge density wave (CDW) Peierls transiti…
