Re: [QE-users] GHz calculation with QE

2020-12-18 Thread Michal Krompiec
Hi Mahdi, Not really. You can get the dielectric function in MHz-THz range from the (temporal) autocorrelation of dipole moment from an MD simulation, but the timescale is way beyond the reach of DFT, by several orders of magnitude. Best regards, Michal Krompiec, Merck KGaA On Fri, Dec 18, 2020 at

[QE-users] GHz calculation with QE

2020-12-18 Thread Mahdi Faghihnasiri
Dear all, Is it possible to calculate the real and imaginary part of the dielectric function in the GHz region with DFT? Can these calculations be done with QE code? Or does it require a special or complimentary approximation and method? Best regards, Mahdi ___

[QE-users] Problem in scf convergence of goethite slab

2020-12-18 Thread Diship Srivastava
Hi, I am doing scf calculation of 010 slab of goethite. It is an insulator with a band gap and antiferromagnetic. I tried the input file generated from https://www.materialscloud.org/work/tools/qeinputgenerator but scf convergence is failing. I tried changing various parameters like mixing beta, m

Re: [QE-users] definition of the hyperfine coupling constant in QE-GIPAW

Dear Davide, I am studying several Cu(II)-based systems. One of them is Cu-L-alanine. Crystallographic unit cell of this complex comprises two Cu atoms and four L-alanine molecules. Hyperfine coupling constants on 13C nuclei calculated by QE-GIPAW were comparable to hyperfine coupling constant

Re: [QE-users] definition of the hyperfine coupling constant in QE-GIPAW

2020-12-18 Thread Davide Ceresoli
Dear Gregor, the hyperfine coupling should be multiplied by the number of unpaired electrons (2*S_z). It also assumes I=1/2. In the past I checked that GIPAW yields the same results of ORCA and Gaussian for molecules in the case S = I = 1/2. I can re-check that. Best. Davide On 12/18/20 1

[QE-users] definition of the hyperfine coupling constant in QE-GIPAW

2020-12-18 Thread Gregor Mali
Hello. Isotropic hyperfine coupling constants A_iso, calculated by QE-GIPAW, can differ by a large factor from A_iso, obtained by Orca. The factor depends on the number of unpaired electrons in the unit cell (used in QE) and in the cluster model (used in Orca). In Orca, A_iso is proportional t
