Dimensionalities of problems: 3D, 2D and 1D

Opublikowano: 01.12.2020 08:55

W-SLDA allows to solve problems

  • in 3D without any symmetry restrictions:  Ψ=φ(x,y,z)                       
  • in 2D with translational invariance along  z direction:  Ψ=φ(x,y)exp(ikzz)                          
  • in 1D with translational invariance along  y and z directions::  Ψ=φ(x)exp(ikyy)exp(ikzz)

By default, W-SLDA Toolkit provides functionals (SLDA, BdG) that are designed for 3D systems. The toolkit can be used to study also strict 2D or 1D problems, i.e one can turn off perpendicular modes exp(ikzz) and exp(ikyy).
