Dear professor Thank you for your directions sir. I will try to understand this procedure. Prasad On Wednesday, July 31, 2019, 5:08:34 p.m. CST, Laurence Marks wrote: N.B., I should of course have said Hermitian, not symmetric. N.N.B., the extension to include spin-orbit is simple.

I guess you should first "understand" the results of a calculation, before you start to experiment with more complicated tasks. After runsp_lapw you saved the calculation. What was the result of this calculation ??? Was it an insulator ?? Did you plot a DOS (also partial DOS including U-f

A little math/analysis may be helpful -- with the caveat that this is my interpretation and I am currently on travel. The density matrix (ignoring spin-orbit for simplicity) "D" is a conjugate symmetric MxM matrix, M=5 for d electrons. From standard linear algebra it can be decomposed as D =

Dear experts I am trying a test case to learn the correct procedure to check local minima. Dear experts I am sending this followup questions related to my previous post on " electron occupancy in dmatup/dn" in the mailing list. In the firt step I finished a "runsp_lapw" and saved. I checked
