Re: [QE-users] DF2 with non-collinear spin

rvv1 also does not work with non-collinear magnetism: from xc_vdW_DF : error # 4 vdW functional not implemented for nspin > 2 though rvv1 is not spin dependent. It seems this should work with no changes. Perhaps I do not understand . Ron > On Oct 21, 2021, at 5:04 PM, Ronald Cohen

[QE-users] DF2 with non-collinear spin

2021-10-21 Thread Ronald Cohen
I would like to use non-local van der Waals DF2 for non-collinear spins with spin-orbit, but get: vdW-DF not available for noncollinear spin case . How hard would it be to include noncollinear spins here? Is it possible just to project to up and down and use that for the DF part? What about

[QE-users] Application of electric field and its effect on ldos

Dear User, I am performing a relaxed calculation for my system of bilayer graphene consisting of 48 atoms. But, my calculation halts after 2 SCF steps stating the error that energy_new > energy_old Please let me know why this error could have been generated and what should I do to correct

[QE-users] Reg: conversion of HOMO-LUMO gap to resistance

2021-10-21 Thread Gorthala Guruprasad
Dear sir/madam, I am Guruprasad, Ph.D. scholar, at IIT Dharwad. I am working on the resistive gas sensors. I design different metal oxide structures, optimize, and calculate SFC, bandgap, and DOS. Then I introduce different analytes to the system and then I calculate bandgap (HOMO-LUMO). The
