[SIESTA-L] Electron occupancies in SIESTA

2007-12-13 Thread Salvador Barraza-Lopez
Hello SIESTA users, I would like to know if there is a way to obtain the electronic occupancies for a given eigenstate in SIESTA. I know one can determine this by the location of the Fermi energy but still would like to know if there is another way to obtain occupancies for electronic

[SIESTA-L] PDOS

Dear Marcos, David, Thank you for pointing out the meaning of the z-flag on the PDOS file. Yet, have you actually plotted the PDOS for spin-polarized systems at some point? I created a small script to plot the PDOS for a very simple system: A Mn dimer. I know the eigenvalues are very close

Hello, I am working with a spin-polarized system and I would like to plot the Projected density of states (PDOS). Looking in the manual, not much info can be found. I have two questions: z=1 is for spin-up electrons and z=2 for spin-down electrons? Also, the actual PDOS data has two columns,

[SIESTA-L] Principal number channels on atom utility

Hi, I am trying to build a pseudopotential file for Mn within GGA-PBE. I have seen Miguel Pruneda's input file which is defined to include 3s, 3p, 3d and 4f channels. The pseudo is polarized (by leaving out two electrons on the 4s channel, which the pseudo program can not generate if s

Hello Chu, The issue here is when you change the ordering on the Chamicalspecies block, you are changing the atomic species also in your coordinate set. Did you leave the coordinates unchanged? For instance, if an atom with coordinates X Y Z 1 was assigned to species 1, then by renaming the

Hi Marcos, I read some time ago a post by Nichols Romero on this subject. From that post, and the responses on it, it appeared that there is not a further implementation of the 'pseudo generation code' for two channels with the same angular momentum. Regards, Salvador.

Hi Cornil, May I inquire how you obtained your value for PAO.EnergyShift? The problem originates from the overlap matrix. Choleski diagonalization requires S to be strictly equal to its transpose. I've seen this problem happening to me a couple times. My advice would be for you to plot your
