Dear Thomas, Thank you very much for your comments and suggestions. You are right the PBE pseudos from http://www.vlab.msi.umn.edu/ resources/repaw/index.shtml contains f-states, but not the LDA ones (I noticed this simply by looking for f-states within the pseudo files). So let me double check, sh

[Pw_forum] Phonon dispersion with LO-TO splitting

2017-11-30 Thread Barnali Bhattacharya
Dear QE USERS, I am trying to reproduce the phonon dispersion with LO-TO splitting of graphene by using quantum espresso code. To get LO-TO splitting, I have added epsil=.true. as well as zeu=.true. in the input file of ph.x. and calculated the phonon modes at q=0 (gamma point). Then I have u

Dear Mohammed, it's hard to give a general advice also because I didn't do many calculation with rare earth elements. Just checking the headers of the pseudos from the vlab side it seems both pseudos (LDA and GGA) have the same states in valence (l_max=3, number_of_wfc=number_of_proj=8). Did

Dear Expert, Here I attached two input files for hexagonal boron nitride (hBN) *hBN1_relax.in* and *hBN2_relax.in*. For *hBN1_relax.in* I'm getting the following error "*Error in routine sym_rho_init_shell (4): lone vector*" (output file is also attached below *hBN1_relax.out*) but for *hBN2_

Dear Barnali, There is no LO-TO splitting in graphene, or more precisely, it is zero. Kind regards -- Lorenzo Paulatto Written on a virtual keyboard with real fingers On 30 Nov 2017 3:59 pm, "Barnali Bhattacharya" wrote: Dear QE USERS, I am trying to reproduce the phonon dispersion with LO
