[Wien] wien2wannier interface

Dear Ellias, I was using wien2k version 13 and wien2wannier version 0.96. With this version of wienwannier interface I am not able to plot wannier function. I am using SrVO3 example. I able to create case m.psiarg and case.psink but not creat XSF file to visualize in xcrsden. So

Hi Ellias, Thanks. In 1.0 version when I am using write_inwf , it tells to give next proj. (3 to go; Ctrl-D if done)? V 2 didn't catch that: SITE and ORB must be given what I have to give for SrVO3? Regards wasim On Mon, Mar 9, 2015 at 8:06 PM, Elias Assmann

Hi Wasim, Of course it is possible to produce plots (in psink+psiarg but also xsf format) using pre-1.0 wien2wannier (the last version was 0.97). If the problem is really the conversion to xsf, you should also be able to use the wplot2xsf script from the new wien2wannier version to do this

Dear Prof Blaha, With reference to the paper *Calculation of the lattice constant of solids with semilocal functionalsPhilipp Haas, Fabien Tran, and Peter Blaha* *PHYSICAL REVIEW B79, 085104 2009* ​For layred metal dichalcogenides (e. g. WS2), does it sound correct if the difference

No. Formally, both LDA and GGA do not take into account van der Waals interactions. vdW interactions are taken into account only with more adanced functionals: http://scitation.aip.org/content/aip/journal/jcp/141/7/10.1063/1.4893329 On Mon, 9 Mar 2015, Osama Yassin wrote: Dear Prof Blaha,

Thank you Tran I raised the question because of the follwing statement i found on the article: RSC Adv. 2015, 5. 18391: DOI: 10.1039/c4ra16966b ​I came across a statement says LDA usually overbinds solid and thus underestimates the lattice constant. However, for many layered materials where
