Spin-Dependent Nonorthogonal Generalized Wannier Functions and their Integration with PAW and Hubbard Corrections in Linear-Scaling DFT
Miguel Escobar Azor, David D. O'Regan, Ali Safavi +3
We present a spin-dependent extension of the non-orthogonal generalized Wannier function (NGWF) formalism within the framework of linear-scaling density functional theory (LS-DFT)…
Accurate bandgaps of photovoltaic kesterites from first-principles DFT+U
Andrew C. Burgess, Lórien MacEnulty, Ethan D'Arcy +2
Streamlined prediction of the electronic properties of photoactive materials warrants a Density Functional Theory (DFT) based approach that (i) yields reliable bandgaps, (ii) is fr…
Benchmarking total energies with Hund's J terms in Hubbard-corrected spin-crossover chemistry
Lórien MacEnulty, João Paulo Almeida de Mendonça, Roberta Poloni +1
The effect of the Hund's J terms in various DFT+U+J corrections to semi-local spin-density functional theory is assessed for a series of four octahedrally coordinated Fe(II) spin-c…
Abinit 2025: New Capabilities for the Predictive Modeling of Solids and Nanomaterials
Matthieu J. Verstraete, Joao Abreu, Guillaume E. Allemand +71
Abinit is a widely used scientific software package implementing density functional theory and many related functionalities for excited states and response properties. This paper p…
Low-energy, ultrafast spin reorientation at competing hybrid interfaces with tunable operating temperature
Servet Ozdemir, Matthew Rogers, Jaka Strohsack +12
Information can be stored in magnetic materials by encoding with the direction of the magnetic moment of elements. A figure of merit for these systems is the energy needed to chang…
Flat-plane based double-counting free and parameter free many-body DFT+U
Andrew C. Burgess, David D. O'Regan
Burgess et al. have recently introduced the BLOR corrective exchange-correlation functional that is, by construction, the unique simplified rotationally-invariant DFT+U functional…
