[Wien] Non linear optical susceptibilities

2016-03-03 Thread Tuan Vu
Dear all
I want to know WIEN2k can calculate Non linear optical
susceptibilities (Second harmonic generation) ? If can, could tell me
how i can get it.


Kind Regards

[Wien] Formula full-potential

2015-12-29 Thread Tuan Vu
Dear Pro. F. Tran

Reason do i need details of the potential:

Time is coming for me to protect my PhD dissertation as part of the
University-supported project.
One of the key question that I will answer before the dissertation council
is that how formula 2.10 in the userguide's.pdf is formed.
The council includes professors from many universities and academies in
Russia, so I can't avoid that questions because the reliability
of the calculation package depends on the full-potential, and so does my
work. With all of my respect, I hope that you can help me
with this question about the full-potential.

Rest regards
PhD. Student Tuan Vu

[Wien] Values magnetic field

2015-12-28 Thread Tuan Vu
Dear all

I have question: What values magnetic field in the use of Wien2k for
SO-coupling. if i select the following parameters for calculation : RMT
reduction = default ( RMT not changed ), Xc = PBE (13), R_Kmax = 7, L_max =
10, Type of Fermi calculation = default (TETRA), mixing factor = default
(0.2), nkpoint = 1000.

Sincerely.

[Wien] Formula full-potential

2015-12-14 Thread Tuan Vu
Dear Prof. F. Tran


The links on the site, we did not find detailed information on the
construction and use of the full-potential in the code WIEN2k. As you can
see the thesis P. Dufek, you mentioned?

We will be very grateful, if you send us this thesis, even in hard copy at:

Russian Federation, Rostov-on-Dou, pl. Gagarin 1, Don State University, the
department of "Electrical and Electronics".

[Wien] Formula full-potential

2015-12-08 Thread Tuan Vu
Dear All



I just read paper “Computation of Materials Properties at the Atomic Scale
// Karlheinz Schwarz 2015” (4.2. The choice of the potential) and User's
Guide (2.2.3 General considerations, formula 2.10), In its general form the
LAPW (APW+lo) method expands the potential in the following form V(r) -
inside sphere and outside sphere.

Can you tell me where can I find more detailed formula for building
potential used in the code WIEN2k? As an example, this is done in optics
article “Linear optical properties of solids within the full-potential
linearized augmented planewave method // Claudia Ambrosch-Draxl , Jorge O.
Sofo // Computer Physics Communications 175 (2006) 1–14.”

[Wien] How to calculate U for 3d-fully filled

2015-06-01 Thread Tuan Vu
Thank Pro. Gavin Abo and Pro. Mehmet Topsakal

i just read paper Calculating the effective U in APW methods. NiO // Georg
K. H. Madsen and Pavel Novak

For NiO , element Ni (3d^6 4s^2) - has 8 d electrons. we can make two
calculations. One with 4.5 ↑, 4 ↓ and one with 4.5↑, 3 ↓ constrained
d-electrons.Have put 8.5 and 7.5 electrons into the core. So for elements
have filled eletrons (d^10)-d-fully filled . How can remove d electrons?

[Wien] How to calculate U for 3d-fully filled

2015-05-27 Thread Tuan Vu
Dear creators!

I have come across a difficulty in realization your program. Can you
explain, how to calculate the parameter U for the case, when the d-subshell
is completely full filled.(example Zn, Ag or 5d Hg, Tl, Pb)

I am grateful to you in advance.

Yours sincerely, the third year post-graduate student of Don State

[Wien] About core-hole calculations for XSPEC:

2015-03-04 Thread Tuan Vu
Dear WIEN2k users


I am using WIEN 14.2 version. I have some question, can explain me!

1) I want to calculate XAS S and P of Tl3PS4 compound. Can i remove
electrons from 2 atom (S and P) at the same time? Or only can
calculate XAS for each case.

2) For XAS need make core-hole in supercell, first remove 1-e of atom
(case.ins)  and add one valence e (case.in2). it's full core-hole? My
question how make 0.5 core hole in supercell, what's file need change?

3)For XSPEC (case.inxs)

***

1.00(S)
2.0 (gamma0)

***

For my case XAS for S and P, what value S and gamma0 for my case?


Sincerely yours
