Basics of the local spin density approximation?

Click For Summary
SUMMARY

The local spin density approximation (LSDA) is an extension of the local density approximation (LDA) that incorporates the spin of particles into density functional theory (DFT) calculations. Erik-Olof Wallman emphasizes that LSDA builds upon the foundational principles of LDA, making it essential for accurate modeling of systems with spin-polarized electrons. For a comprehensive understanding, Kieron Burke's online draft on DFT is recommended as a starting point for beginners.

PREREQUISITES
  • Understanding of density functional theory (DFT)
  • Familiarity with local density approximation (LDA)
  • Basic knowledge of quantum mechanics and spin
  • Access to academic resources or libraries for further reading
NEXT STEPS
  • Read Kieron Burke's online draft on DFT
  • Explore advanced texts on local spin density approximation
  • Investigate applications of LSDA in computational materials science
  • Study the mathematical formulation of spin-polarized DFT
USEFUL FOR

Researchers, physicists, and students in the fields of quantum mechanics and computational materials science who are looking to deepen their understanding of spin-dependent phenomena in density functional theory.

Does anyone know the basics of the local spin density approximation?

You'd have to search for spiral equation i guess.

Best wishes Erik-Olof Wallman
 
It's just like the local density approximation except that now you're including the spin of the particles in your equations and subsequent calculations. Which sounds a bit snarky, perhaps, but that's all there is to it.

If you want real basic, go take a look at Kieron Burke's online draft on DFT http://dft.rutgers.edu/kieron/beta/

There are of course far more rigorous and lengthy explanations, but they aren't too hard to find (just look in your nearest library).
