Dear Eduardo,
 I was using siesta1.3p with no patches, hence the error (I found a 2004 
post by Pablo Ordejon mentioning this problem). I switched to 
siesta-2.0 and it is gone.


 Thank you for your assistance.

Hello list,
I am doing a calculation where a gold surface is covered with a magnetic

I first performed a calculation with a gold pseudo and basis including the 
5d electrons. My basis was built explicitly and had 2zetas for the 6s, and 
1 zeta for 6p and 5s channels. The band structure I get is very similar to 
that from plane-wave codes.


Then, I built a pseudo without the 5d channel.
I built my basis explicitly once again. For reasons I do not completely 
understand I am getting the following warning:

There is something not quite right. Could you share your experience on the

[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 temperatures 
greater than zero (or of the order of an energy gap). Your comments will 
be greatly appreciated.

[SIESTA-L] PDOS

2007-11-14 Thread Salvador Barraza-Lopez

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 to those
obtained from a trusted plane wave code. The occupations as obtained from
the EIG file and the location of the fermi levels from standard output are
also consistent with the results  from that plane wave code.

  If things are as both of you indicate, I should get, for the first 
column

of the data the up-spin states at particular energies, and the
corresponding down spin entries from the second column.

  Instead, what I have is a second column filled with zeroes (not a single
peak when plotted, see red line in attached figure), and a first column
that actually resembles the *sum* of spins (blue line; I am attaching a
figure for clarity, hope it is okay). I know there are issues with
non-ortonomal basis sets and that it is valid to get negative dos from
those  but, really, it looks like what I am getting is not the spin-up
component but rather the sum.

  I am looking into the pdosg.F file to try to fix it (line 206). Can not
determine how to do it momentarily. Comments and help on this matter will
be greatly appreciated.

[SIESTA-L] Principal number channels on atom utility

2007-10-17 Thread Salvador Barraza-Lopez

 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 channels 
are already defined (the 3s channel).


Here is one such sample pseudopotential generation file:

   pe Manganese

  1.00  1.00  1.00  1.00  0.00   0.3


 Looking at the OUT file after running atm, I have found

 I wonder why the n channel is running from 1 to 4 in those lines. All 
the rest in the OUT file looks normal. Have anyone else seen this? I guess 
it is just an innofensive bug in the program when it writes these 
things to the OUT file, without repercusions for the 
actual generated pseudos, but would like to be certain that is the case.

Re: [SIESTA-L] atom label ordering problem

2006-11-21 Thread Salvador Barraza-Lopez
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 atomicspecies block 
this same atom now belongs to the complimentary specie (originally, to 
species 2). So you really need to change the atomicspecies block, and the 
labels on your coordinate set, which assign the atomic species to an atom 
at position XYZ.

Best,
Salvador.

Re: [SIESTA-L] Erbium

2006-10-14 Thread Salvador Barraza-Lopez
Hi Simone,
 As previously mentioned, your rcut are too small. I bet you are 
seeing a *linear* decrease on the total energy against lattice 
constant with your pseudo, aren't you? I've seen this behaviour myself 
whenever the rcuts were too small.

 Try the suggestion by Oleksandr. How abot all rcuts being set to 2.0 or 
somethig like that?  
 Another thing you might want to fix is your radius for core correction: 
It is beyond your rcuts. usually this radii has to be as close to zero as 
you can, without making the pseudo too hard. There is a PRB paper by Marc 
Pederson, at NRL, on this. I've tried this with Siesta 
and too-small rcuts were in ocasions responsible for ghost states. So 
proceed with caution in that respect.

 I'd like to have the 5s and 5p orbitals as semicore and the 4f, 5d, 6s
 and 6p as valence, just like in the Ba example in the atom manual.
 So after choosing the various r_c like suggested by Mr. Salvador Barraza-Lopez

 The tests for the pseudopotential seem to be OK (to get a qualitative
 idea of the pseudos, have a look at the attachment).
 As I have semicore electrons I have to specify a PAO Basis. I use for
 Erbium the basis suggested by Valeria  Miguel for Lanthanium (see
 the following lines or the SIESTA website), which includes 5s and 5p as
 semicore
 (simple zeta). The 6s and 5d orbitals are described with double zeta, and a
 simple-zeta 6p is used as polarization.

 Now, with these values I do not get any minimum in the total energy curve
 for bulk erbium (HCP structure) for different values of the lattice
 constant!!!
 This is not due to the deficit of LDA in simulating strong correlated
 electrons, because at least for the structure LDA is good enough as shown in
 the past.
 Can someone suggest me a better choice for the parameters and/or explain
 me why does my pseudopotential fail to reproduce metallic erbium? Do I
 make some mistake in the choice of the r_c or is the basis inadequate to
 correctly reproduce the erbium orbitals?

 The HGH pseudos downloadable for ABINIT are O.K. Is it possible to convert

Re: [SIESTA-L] input_phenol

2006-10-06 Thread Salvador Barraza-Lopez
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 total energy against PAO.EnergyShift (yes, there will be 
*some* values of EnergyShift for which the run will be successful I 
believe). There is an extra variable indicating a magnitude for the split 
between orbitals, I can't remeber it off hand. Try this other variable 
too.

 One extra observation. Have you made tests of total energy against 
Meshcutoff? Your value is on the low limit.

 Best,
Salvador.

 of the exchange-correlation functional. So that's
  why I hoped if I download that particular pseudopotential for Bismuth,
  the things would work.
 
  I guess I could try with LDA.

 The problem is not LDA or GGA, but then one word of caution: don't mix LDA
 and GGA pseudopotentials, which will not give you good results (I'd say
 good results would simply be a coincidence in this case). If you decide
 that your pseudos are GGA, then they should all be GGA, or else all LDA.

 I have to say the distribution function proposed makes calculations really 
fast for metals. I'll keep using it from now on. I did not find big changes

[SIESTA-L] Gold band structure

2006-08-29 Thread Salvador Barraza Lopez
Dear SIESTA users,
 I have been working on creating a pseudopotential for gold. I started checking 
postings and found a couple dating back to 2003. The pseudo there is LDA. I 
have tried a good number of parameters. I've taken matching radii close to the 
rmax in the all-electron calculations; have tried neutral and ionized 
configurations, core corrections, relativistic corrections as well as pseudos 
without: I think I have explored in a consistent form the options I can get 
from the pseudo.

 The problem I have is the following: The band structure looks reasonable, but 
I can *not* reproduce a degeneracy at the W-point for the second and third 
bands. The bands at the Gamma-K direction also look different from other 
published work and abinit test calculations. I also see the lack of splitting 
in a recent siesta calculation (Fig 6 on J. Phys. Cond. Matter 18 (2006), 7999.

 I feel I have tried what I can think of, but haven't had success. Am I doing a 
simple procedural mistake?

 Atached is a copy of my siesta input file for an LDA, spin unpolarized, 
non-relativistc pseudo; the one present in the listings from 2003. I have a 
database of pseudos, but all present the aforementioned splitting for the 
second and third band at the W point. As I am running out of ideas, I am eager 
to hear your comments and suggestions.

 Best regards,
Salvador Barraza

[SIESTA-L] Charge 'density(?)' from atom program

2006-07-11 Thread Salvador Barraza Lopez
Dear developers and users,
 I have a couple questions regarding the charge plot from an 
all-electron calculation (or pseudo, does not matter) in atom.
 The first one is about the units in this plot. The 
horizontal scale is in Bohr but what would be the units for 
the vertical plot?

 Perhaps related to the previous question is: How is one to 
interpret the charge plot? It is the radial part I suppose, 
so it is not a density. (I could see this as being the 
density only for the case of closed shell atoms.)

Waiting for your comments on this matter,
Salvador.



Re: [SIESTA-L] Not converged ?

2006-06-29 Thread Salvador Barraza Lopez
Hi,
 The variables you want to modify are DM.MixingWeight and 
DM.NumberPulay. If you can't make the run to converge, then 
make use of DM.NumberKick and DM.KickMixingWeight. Increasing 
the temperature might also help. Please have a careful look 
at the manual for descriptions and default values of those 
variables.

The DOS and PDOS are calculated independently from the

concurrently to increase sampling points and to decrease the

  Any Would you like to let me know how can we choose this parameter for Metl, 
Insulator, or Super conductor.
  Thnx

Dear Michael,
   
  I recomend to use two programmes for generating coordinates for carbon 
nanotubes.They are tube gen and wrapping.These can be downloaded from 
onlone.Addresses are
   
  http://turin.nss.udel.edu/research/tubegenonline.html
   
  and 
   
  www.photon.t.u-tokyo.ac.jp/~maruyama/wrapping3/wrapping.html
   
  once you have the xyz or pdb files for nanotube you can visualise the 
structure of nanotubes in Crystal maker or Chemcraft.Using Chemcraft you can 
add atoms or chains.

Hello Users
  I read many artcicle about tranition metal(TM) or other element filled 
Nanotubes i.e [EMAIL PROTECTED]
  I know there are some softwares which can generate the atomic cordinates of 
Nanotube.
  I dont know how we can find the atmic cordinates for Fe filled Nanotubes, 
bcos Fe may be in BCC,FCC,Nanowires or in Atomic form.
  Is there any one who can help me in finding the cordinates of Fe or any other 
TM filled Nanotubes.
  I will be very thnkful for your help.
  Thnx
  Mich.

[SIESTA-L] Questions on OrderN procedures

2005-02-23 Thread Salvador Barraza Lopez
Dear SIESTA-developers/users

 I have explored the mailing list trying to obtain info regarding orderN
procedures. But there is not much. Or to be precise, there is not enough
for me to make a sucessful run. I have unstabilities after the second scf
cicle. The gradient goes out of bounds.
The fdf file in this (test) case works well with serial procedures. I am
planning to build more complex systems and so I am using it for the purpose
of attempting a sucessful run with the orderN algoritms.

Thank you in advance for your advice
Salvador Barraza
