[Pw_forum] Fwd: Atoms are missing in the pdos output

2013-05-22 Thread Paolo Giannozzi
Most HGH pseudopotential files do not contain atomic wavefunctions.
No atomic wavefunctions, no PDOS

[Pw_forum] Modelling a 4-system high entropy alloy

2013-05-22 Thread Zhao Y Leong
Hi everyone,

Pardon the neophytic question(s) as I've just only started using QE.

I'm interested in modelling a four element based high entropy alloy to find
the energy band and fermi energy; according to the XRD tests I've done the
structure of the alloy is Cubic F3-M3 255 with a parameter of 3.57
angstroms.

I've tried using example_7 as a guideline but adding additional atoms into
a 255 group doesn't seem to work because the bravais symmetry gets
duplicated. Would it then be possible to input the elements into a a
triclinic system using coordinates of (0,0,0), (0.5,0.5,0),(0.5,0,0.5) and
(0,0.5,0.5) or is there another way to construct a 12 atom FCC unit cell
while randomising the atoms inside between the four alloys?

For now will be looking at using some ultrasoft pseudo-potentials. Will
that be fine and is it necessary to calculate the cut-off point for ecutwfc
as well or would it be fine to use a nominal value of lets say, 25?

Thank you,
Zhao

As you can see atoms 1, 15,16,17 are missing here also. I tried with lsym =
.false. also, but it didint work

[Pw_forum] no band gap appear in the bands eigenvalues in relaxtion though a 3 ev band gaps should be found

2013-05-22 Thread Yong Xue
Dear all
I am doing relaxation for a system of C, O, and H2 which should have a 3eV
band gap. however, in my relaxation calculation, from the eigenvalues it
shows no band gap. So, I cannot trust the further nmr reulst. after this
step. I also paste my input for relax down, can anybody tell me what is the
problem?
as seen:

[Pw_forum] lambda.x crash

2013-05-22 Thread feng.zi...@ireq.ca
Spelling correction: is -> if 

Hi Jelena,
Sometimes you should also check if the contents of the files "elph. xxx" are 
correct. Have you done that?

[Pw_forum] lambda.x crash

Hello!
I'm trying to do electron phonon calculation on monolayer graphene. 
When I try to calculate Tc using lambda.x i get this error:

At line 78 of file lambda.f90 (unit = 4, file = 'fort.4') Fortran runtime 
error: End of file

and empty file fort.4 shows up in my working folder.

Here is lambda.in i use.

[Pw_forum] symmetry in wannier

2013-05-22 Thread ding
Dear Wannier users,
How to apply symmetry protection in Wannier 90 code? The unit cell is 
LaFeAsO, the space group   is 129_P4/nmm, and one unit cell contains two 
equivalent Fe atoms. I use the 10 Fe 3d orbitals to get the effecitve  tight 
binding Hamiltionian.  But  I  found that the chemical potentials of  the five 
3d orbitals  from the two equivalent Fe atoms is different. For example, the  
chemical potential of the dxy orbital from one Fe atom is different from that 
of the orther Fe atom. Can anyone give some suggetions?
 Thanks a lot !
