[Wien] DFT+U method

2019-08-28 Thread 杨柯
Dear Experts, I'm testing the DFT+U part right now. I'm a little confused here and hoping one of you could help me out. The ORB part of Wien2K-Usersguide has a detailed description of the three different methods of LDA+U. The effective U approach (SIC) is recommended. The following is an exa

I just want to add that DOS(E) = \sum \delta(E - \epsilon_{nk}). (n is band index). For regular DOS, summation is over the whole Brillouin zone. In your case, summation is restricted to k-points along a path. And weight for each k-point is either 1 (spin polarized calculation) or 2 (non polarized).

Not with standard wien2k tools. However, you can write your own little programs, eg. reading the case.qtl file for an arbitrary k-mesh of your choice and do a "root sampling", i.e. divide your energy mesh into some intervals and count the number of eigenvalues (times the multiplicity of the k-
