Web5 Aug 2024 · The Hubbard U parameters they employed were: U(Ga 3d) = 5.7 eV, U(In 4d) = 3.7 eV. This scatter in the Us is unfortunate, since LDA+U offers an attractive route to mitigate the deﬁciencies of the standard DFT at virtually no computational over-head. Reliable LDA+U parametrization can enable computing systems that are inherently Webread the Hubbard_U (or Hubbard_V) parameters from the PW input file 'file': read the Hubbard_V parameters from the file "parameters.in" which can be generated after the linear-response calculation (using the HP code). This option has a higher priority over the Hubbard_V if they are specified in the input. This ...

WebV, like U, is a Hubbard parameter, but contrary to U it describes inter-site electronic interactions and not on-site ones (e.g. how a 3d Hubbard manifold talks to the 2p orbitals of oxygen ligands). The idea of including V in the DFT+Hubbard formulation comes from the "extended Hubbard model", where both on-site U and inter-site V parameters are used. The Hubbard model is based on the tight-binding approximation from solid-state physics, which describes particles moving in a periodic potential, typically referred to as a lattice. For real materials, each lattice site might correspond with an ionic core, and the particles would be the valence electrons of these ions. In the tight-binding approximation, the Hamiltonian is written in terms of Wannier states, which are localized states centered on each lattice site. Wannier state…
