Re: [Pw_forum] Pseudopotential Radius for K

2018-01-12 Thread Lance Kavalsky
Hello,


Do you know how I could go about verifying if this is the case? Especially 
since the local term should become Coulombic in the limit of large distances 
away, so there will be other components to this term as well (unless I'm 
mistaken).


Also, in general, do you know how the reference states are selected for the 
summation in the nonlocal term? Why might the d and f orbitals be selected in 
this case?


Thanks for your help,

Dear Lance Kavalsky,

   A wild guess: s was the local component of the pseudo potential? I
agree, the cut-off radius should have been listed though.

Re: [Pw_forum] Pseudopotential for indium

2017-12-07 Thread Pascal Boulet
Dear Nicola,

Yes, indium is metallic.  The parameters I use to treat it are:
  occupations= 'smearing',
  smearing   = 'cold',
  degauss= 0.02,

There are 13 valence electrons in indium and 34 Kohn-Sham states. I have 
checked the band occupations for all the k-points; at least the two uppermost 
bands are empty, in most case even more.

Here are the results of my tests.

Exp. : 3.2449 x 3.2449 x 4.9420 angstroms

--
K-points | Ecut/Ry | Ecutrho/Ry |   PSP | Fntal | cell parameters 
--
8x8x8=40 120   1200   PAW nrel PBE3.2168 x 5.3095
8x8x8=40 150600NC nrel PBE3.2213 x 5.3194
8x8x8=40  50500   PAW rel+SOPZ3.0786 x 5.0095
8x8x8=40 120   1200   PAW rel+SOPZ3.1032 x 5.0938
12x12x12=126  50500   PAW rel+SOPZ3.1692 x 4.7429
16x16x16=288  50500   PAW rel+SOPZ3.1340 x 4.8412
12x12x12=126 120   1200   PAW rel+SOPZ3.2094 x 4.7811
16x16x16=288 120   1200   PAW rel+SOPZ3.1647 x 4.9076

The best result is the last one. So the PAW of In is very hard (!) and need a 
huge amount of k-points… This is the first time I see this problem with a PAW 
PSP of the library… 

Thank you all for your hints.

Dear Nicola,

You are right I also noticed that the ‘pseudo' state energies match very well 
the AE ones. 

Regarding the alloys Vegard’s law should hold according to experimental data. 
We are indeed using supercells.

I am currently running tests on pure indium. As mentioned by Paolo, the mass is 
irrelevant in the results for static calculations (as expected!). I have 
preliminary results with relativistic+SO calculation that are a bit better:
3.0786 x 3.0786 x 5.0095

Recall: 
exp.: 3.2449 x 3.2449 x 4.9420
previous calc.: 3.2168 x 3.2168 x 5.3095

This is obtained with Ecut=50 Ry Ecutrho=500 Ry, 8x8x8 kpts=40 kpts
With these parameters c improves substantially (1.4% off) but a and c worsen a 
bit (5% off).

I am running a test with more kpts first. In a second step I will increase Ecut 
and Ecutrho and will report to the forum.

Pascal

 Hello,
 can you try with a much higher cutoff (100 Ry or more) and see if the
 lattice parameter improves? I've noticed that sometimes pslibrary pseudos
 are much a harder than they look, especially when converging stress

 Dear all,

 We are working on some In-containing semiconductors M(1-x)In(x)L. M is
 supposed to be a smaller atom than In. We are facing the problem that when
 we vary x from 0 to 1 the cell parameters is decreasing instead of
 increasing. Although this may happen, it should not be the case here since
 ‘pure’ ML has a smaller cell parameter than ‘pure’ InL.

 We have run some calculations on crystal indium using the PSL library
 pseudo potentials (both PAW and USPP). one of the calculated cell
 parameters are miles away from the experimental ones:
 exp.: 3.2449 x 3.2449 x 4.9420 angström

 Does anyone have tested the In pseudo potentials of the PSL library or
 faced this problem with indium?

 Thank you for your help and time.

Re: [Pw_forum] Pseudopotential for indium

2017-12-06 Thread Saif Ullah
Yes, I think 114.818d0 should be used instead of 49.0. I'm pretty much sure
that this may be the reason (or one of the reasons). Once, I used the
atomic mass of B for Be and I faced this kind of weird situation.

Anyway, I'm running the same geometry with 8x8x6 kpoints.

Thanks

Dear Pascal,


the comparison with all-electron calculations looks good to me - see
here for tests and for the other pseudos:
http://materialscloud.org/sssp/results/In_conv_patt.png

Comparing with expts is more delicate -  c/a with PBE is
quite a bit off e.g. in ferroelectric perovskites.

Re the alloy, how are you constructing the intermediate concentrations?
Supercells? (Vegard law should hold)

Iit is used only by molecular dynamics, not by structural optimization.

I don't remember In to be an especially nasty element, at least for simple

Dear Boulet,

I think I found where the error is. You are using the atomic number of In
instead of its atomic mass.

Hello,
can you try with a much higher cutoff (100 Ry or more) and see if the
lattice parameter improves? I've noticed that sometimes pslibrary pseudos
are much a harder than they look, especially when converging stress

[Pw_forum] Pseudopotential for indium

2017-12-06 Thread Pascal Boulet
Dear all,

We are working on some In-containing semiconductors M(1-x)In(x)L. M is supposed 
to be a smaller atom than In. We are facing the problem that when we vary x 
from 0 to 1 the cell parameters is decreasing instead of increasing. Although 
this may happen, it should not be the case here since ‘pure’ ML has a smaller 
cell parameter than ‘pure’ InL.

We have run some calculations on crystal indium using the PSL library pseudo 
potentials (both PAW and USPP). one of the calculated cell parameters are miles 
away from the experimental ones:
exp.: 3.2449 x 3.2449 x 4.9420 angström
calc.: 3.2715 x 3.2715 x 5.4541 angström

Does anyone have tested the In pseudo potentials of the PSL library or faced 
this problem with indium?

Thank you for your help and time.

Re: [Pw_forum] Pseudopotential in calculation of interatomic force constants.

2017-11-10 Thread 方子明
Dear expert,
Thank you so much for helping me.
But can you tell me why many imaginary frequencies appears in my Gamma point 
calculation? And how to remove these imaginary frequencies?
These are my scf.in file, ph.in file and ph.out file. (I just use the 
experimental crystal parameters and do not optimize.)

Thank you again.
Best,
Ziming Fang.

There is no reason for which a PAW pseudopotential cannot be used in a 
supercell. If your calculation does not converge, the reason is elsewhere.

With the minimal amount of information you provide its impossible to say 
anything.

2017-11-10 Thread 方子明
Dear Experts,
I have calculated the IFC for a supercell of a bulk. However, when I chose the 
PAW pseudopotential, it appears that no convergence has been achieved. While 
for USPP, the convergence can be achieved. Does this mean PAW can not be used 
as the pseudopotential to calculate IFC? If not, how can I achieve the 
convergence?

Re: [Pw_forum] Pseudopotential generation of Silicon in [Ne] 3s2 3p2 3d0 configuration

2017-06-20 Thread Ari P Seitsonen


Dear Harshit Bharti,

  Indeed this is the standard procedure, the method of Don Hamann (PRB 
from 1990's) for unbound states. Do you need the orbital wave function 
somewhere else than in the DFT Hamiltonian? There the discontinuity does 
not matter, because i) the d channel is usually the local one for Si and 
thus the wave function is not used and ii) in the Kleinman-Bylander 
operator (V_l - V_local) |phi_l> the Delta V_l = (V_l - V_local) vanishes, 
or goes to zero, at the core radius, thus making the operator approach 
zero, and the discontinuity in phi_l does not matter.

Dear Harshit Bharti,

  What do you mean with "wrong pseudo potential for 3d orbital"? Please 
provide more information, about your input and why you say that the pseudo 
potential is "rong"? It is possible to generate a pseudo potential in the 
neutral or an ionised configuration; actually Si is one of the easiert 
elements to create a pseudo potential for.

Dear Amir,

 in the  pslibrary project you can certainly find an US pseudo for Silicon.
 however Silicon is one of the least problematic elements and you 
probably don't need an US pseudo for it. The code can with no problem 
handle different pseudo types in the same run.

[Pw_forum] Pseudopotential dependent projection when using DFT+U

2014-05-24 Thread Ari Paavo Seitsonen
Dear Zhongnan,

  You can do it during molecular dynamics using section

CP2K_INPUT / MOTION / CONSTRAINT / COLLECTIVE

and specifying it in

CP2K_INPUT / FORCE_EVAL / SUBSYS / COLVAR

  During geometry optimisation ("GEO_OPT") it is not possible to constraint
a bond exactly, but one can work with RESTRAIN and make the condition be
_almost_ fulfilled.

  The FIXED_ATOMS works only if the bond to be fixed is along one Cartesian
axis and the specific coordinate along the direction of the bond can be
fixed; this is usually not possible, but it depends on your system.

[Pw_forum] Pseudopotential dependent projection when using DFT+U

2014-05-23 Thread Zhongnan Xu
I have a question on how the contribution of the Hubbard U depends on the
pseudopotential.  My understanding is that the penalty applied to the total
energy with DFT+U is dependent on a projection of a basis set. My question
is whether this basis set is determined by the pseudopotential.

[Pw_forum] Pseudopotential combination

2014-05-17 Thread Elliot Menkah
Hello Everyone,

I'm making an adsorption study of carbon monoxide(CO) on pure nickel(Ni) 
surfaces.
I use the pseudopotential Ni.pbe-nd-rrkjus.UPF to optimized the pure 
nickel system.
Is it wrong to use C.pbe-van_ak.UPF for carbon and O.pbe-van_ak.UPF for 
the oxygen rather than using C.pbe-rrkjus.UPF and O.pbe-rrkjus.UPF
When I use the *pbe-van_ak.UPF* to optimize the CO separately, I get an 
energy of *-75.5429425135* Ry whereas *pbe-rrkjus.UPF* gives me an 
energy of *-75.1901795049* Ry.

In consideration of the energetics and stability, I want to go in for 
the pbe-van_ak.UPF for the system of CO on Ni surface. Is it wrong please?


Kind Regards,

Elliot

Dear users,

 

I have a quick question to ask - if I wish to perform epsilon.x in
investigating the optical properties, is it not the right choice to use the
ultrasoft, but with the norm-conserving pseudopotential when running the scf
calculation instead?

[Pw_forum] Pseudopotential format for virtual.x

2013-10-03 Thread Rui Mao
Dear QE users,

I was trying to use virtual.x to generate mixed Pseudo-potentials(PPs)
recently.

However, I was having trouble even getting the PPs to be read by virtual.x
The detailed error message is attached at the end.

After a little bit of research, I found that virtual.x only accepts old
Vanderbilt PP format, while nowadays, PPs are written in new XML format.

I am wondering whether there is any auxiliary conversion tool available in
QE that can transfer the new XML format to the old Vanderbilt format?
Or is there any way to make virtual.x to accept new XML format?

Error message from virtual.x (fails at the very beginning of reading input
PP files)

 Generate the UPF pseudopotential for a virtual atom
 combining two pseudopootentials in UPF format

  Input PP file #  1 in UPF format > Se.rel-pz-nc.UPF
  IOS=0   1   4
  Reading pseudopotential file in UPF format...

 %%
 from scan_begin : error # 1
 No HEADER block

 stopping ...


Thank you very much!

you shouldn't be. The number of valence electrons is 12,
the pseudopotential was generated on a ionic reference 
configuration with 11 valence electrons (Ti+)

12. while pseudopotentials are typically created from a neutral
configuration, it need not be like that. there are far more crazy
configuration use, e.g. with fractions of electrons. this is usually
done to improve the transferability of the resulting pseudopotential
and/or to avoid ghost states.

please read up a little on pseudopotential generation. it will be very useful.

11. I'm confused. What is the correct number of valance electron for Ti?
Will you give me some assistant?
Thanks in advance.

Dear Romeda, and everyone else,

you should try out the ps_library from QE forge. Download it,
and ready carefully the AAREADME. Thank Andrea Dal Corso in
the process. Report on this list any result that looks odd.

We compiled all the pseudos, and they can be found here:
http://theossrv1.epfl.ch/index.php?n=Main.Links

Look for USPPs using e.g. pbe, i.e. pbe.tgz . Read carefully
the readme file mentioned above regarding the different directories
pseudopotentials, pseudopotentials_tot, and pseudopotentials_alt.

if you can't find the pseudopotential, you have to either
make it yourself or find a way to convince somebody to
do it for you. since generation of pseudopotentials can be
tedious and is generally a rather thankless profession,
you may need some very good arguments for the latter.

Dear Ananya.

If I remember correctly, in the ps-library distribution 

there is a Na US pseudopotential with s and p semicore states

you can modify the input to make it NC (the US generation is actually a 
2-step process in which the NC version is generated first).

It's probably going to be a hard pseudo.

no. not at all. london=.true. uses DFT-D
which is an empirical correction to "regular"
functionals like BLYP and PBE and alike.
this is different from what emine was

please have a good look at the related publications

Dear Bani Adam
 maybe it would be more useful if you clarify what is your request 
about pseudopotential and vdW.

 are you referring to the XC functional to be used ? then of course 
one should use a pseudo generated with that XC, or in case this is not 
available with an XC as close as possible to it... and this was the 
meaning of Emine's reply
 or are you asking if some specific typer of pseudo can "by itself" 
give better descriptionof vdW system ?.. then please think about the 
lines suggested by Axel..

or maybe you are thinking about  something else.. please clarify

best,
stefano

[Pw_forum] pseudopotential

2012-07-25 Thread Emine Kucukbenli
Perhaps knowing the physics behind it, the OP assumed that  
vdW-relevant distinguishing factor between pseudopotentials is the XC  
functionals they are generated with. In that case the question would  
be legit and the answer I suppose would go like the following:

Choose a flavor of vdW you want to use, then

for input_dft="vdW-DF" use a revPBE pseudo
for input_dft="vdW-DF2" use a revised-PW86 (the last commit on this  
was some 5h ago so i would use w caution.)

instead, input_dft="vdw-df-c09" or "vdw-df2-c09" should both be used  
with pseudos generated with c09x

And follow the modifications to Modules/funct.f90 file with care for  
addition of new vdW flavors :)

please think about this for a little bit:
- in what range (i.e. distance from the atom core) does a pseudopotential
 modify an (atomic) wavefunction and what is it supposed to be like beyond
 that range?
- in what range, i.e. distance between two atoms, do van der waals
  interactions matter?

if you think this through, you should be able to come up with an
answer to your question by yourself.

your question is not related to the pseudopotential
of silver, but to the meaning of energies in charged
cells, if I understand correctly. Energies for charged
cell should be handled with care and cannot be directly
compared to the energy for the neutral cell.

[Pw_forum] pseudopotential for silver

2012-04-01 Thread Никита Вакула
Hi all!

I am new to Pwscf and to this forum. I have a question about pseudopotential 
for silver: if I calculate the energy of pure silver atom and its cation in 
vacuum then they (energies) are ok. But if I optimize the structure Ag_surface 
(when Ag or its cation adsorped on a dielectric surface, for example, SiO2), 
then the absolute value of charged Ag+_surface energy is greater than the 
absolute value of neutral Ag_surface energy. Could you please tell me how it 
could be? I used Ag.pbe-d-rrkjus.UPF.

Thank you in advance!

Best regards,
Nikita

[Pw_forum] pseudopotential

To QE developers,
  I am now trying to simulate some XAS spectrum. In order to take into
account the electron-hole interaction, I need to generate a pseudo
potential which has a hole in the 1s state of O. I am wondering whether
such a special psp of O is equivalent to a psp of F with reference
configuration 1s^{1}2s^{2}2p^{5} i.e. +1 configuration but with one
electron missing in the 1s state? Is that the way to generate such a
special O psp?

[Pw_forum] pseudopotential for Uranium

2011-02-20 Thread Sharat Chandra
Hi

I am trying to generate a pseudopotential for Uranium for use in my 
calculations for UFe2 compound. I have tried converting the fhi PPs available 
from the ABINIT web site, as well as generating the TM PP based on the 
publication by Crocombette etal, Phys. Rev. B, 64, 104107, 2001, and also 
trying to generate the ultrasoft PP, using the atom code. I have checked the 
mailing list and did not find any discussion with emphasis on this topic.

The fhi PPs have 6 electrons, while the PPs generated using the PRB data have 
12 electrons.

I have not been able to get the proper lattice parameter and bulk modulus of U 
in fcc phase, published in the same paper, which are 134.3 a.u.^3 and 154 GPa. 
I either get too large values, or too small values, based on the number of 
electrons in the PPs.

Can some one please tell me what I am doing wrong? If any one can tell me what 
are the proper values for rcore and rcloc, I will be very grateful. I have put 
below the different inputs that I have used to generate the PPs.

Thank you very much.
Actually, this warning not only show up at the beginning, also after the
pseudo potential generated.
" --- End of pseudopotential generation

 warning: wfc  5 2 not converged
 warning: wfc  5 1 not converged
 warning: wfc  4 3 not converged
 warning: wfc  5 2 not converged
 warning: wfc  6 0 not converged
 warning: wfc  6 1 not converged

By the way, How can I check whether the wavefunctions are sufficiently
localized or not.
And I did not get the line "eps = 3.2E-16  iter = 36"
