[Pw_forum] Tetrahedra occupations not provided for DOS.

2017-05-23 Thread B S Bhushan
Dear QE experts, I have extracted DOS of a 50 atom graphene system. While performing SCF I have considered occupations=smearing, smearing=mv, degauss=0.005. However, while performing "NSCF", I forgot to change the occupations to Tetrahedra and left the occupations option same as in SCF

[Pw_forum] Method to interpolate q-mesh in calculation of electron-phonon interaction.

2017-05-23 Thread Rakesh Parayil
Dear all, I would like to ask a question regarding the method to interpolate q-mesh as described in arXiv:cond-mat/0504077 as implemented in Quantum espresso. To obtain an accurate result we should study the convergence of \lambda as a function of k-mesh and q-mesh. In that paper, the phonon

Dear all! Is it possible to separate forces on an atom-to-atom basis (A-B, A-C, B-C, in a compound with atomic species A,B,C, for example)? Grimme-D2 seems to describe a H-bonding phenomena quite well (judging from the orientation of H---Br) but being able to actually read the force (from

Hi Aldo, The critic2 program can help you with this by calculating a core contribution using its internal density tables: https://github.com/aoterodelaroza/critic2 If in your system you have, say, C, H, O, and N, and the pseudos represent the usual number of electrons, you can do: crystal

Dear QE users, I am trying to work out the Bader analysis on my system (molecules adsorbed on a metal surface) with the complication that I used US pseudos and I would not like to re-run it with PAW ones. So I tried the easiest option, i.e. with the charge density as-is but the result was not
