Physical spin torques from exactly constrained exchange-correlation torques
Jacques K. Desmarais, Kamel Bencheikh, Giovanni Vignale +1
The problem of capturing physical spin torques in non-collinear magnetic systems has dominated the scene of spin-density functional theory (SDFT) in the last two decades. Progress…
Altermagnetism, Kagome Flat Band, and Weyl Fermion States in Magnetically Intercalated Transition Metal Dichalcogenides
Avinash Sah, Ting-Yong Lim, Clayton Conner +5
Altermagnetic (AM) compounds have recently emerged as a promising platform for realizing unconventional quantum phases, enabled by their unique spin-split band structure at zero ne…
Meta-Generalized-Gradient Approximation made Magnetic
Jacques K. Desmarais, Alessandro Erba, Giovanni Vignale +1
The Jacob's ladder of density functional theory (DFT) proposes the compelling view that by extending the form of successful approximations -- being guided by exact conditions and s…
Electron localization function for non-collinear spins
Jacques K. Desmarais, Giovanni Vignale, Kamel Bencheikh +2
Understanding of bonding is key to modelling materials and predicting properties thereof. A widely adopted indicator of bonds and atomic shells is the electron localization functio…
Spin-currents via the gauge-principle for meta-generalized-gradient exchange-correlation functionals
Jacques K. Desmarais, Jefferson Maul, Bartolomeo Civalleri +3
The prominence of density functional theory (DFT) in the field of electronic structure computation stems from its ability to usefully balance accuracy and computational effort. At…
