Dear SungHwan, please refer to http://arxiv.org/pdf/1402.0486.pdf and http://urania.sissa.it/xmlui/bitstream/handle/1963/5797/turboTDDFT-CPC.pdf?sequence=1 for more details. In the output of the postprocessing chi_1_1 is the xx component of the dynamical polarizability, chi_1_2 the xy component,

[Pw_forum] absorption spectrum constant of turboTDDFT

2016-07-19 Thread SungHwan Choi
hi, I am a newbie for turboTDDFT. Now, I ran a simple example. It was assume. Now I have prefix.plot_chi.dat file. then I don't know how to generate absorption spectrum from that file and dielectric constant values. As far as I understood, the absorption spectrum is related to imaginary part

I don't know how you manage to always get exotic errors. I made a quick test with reduced cutoffs, Gamma-only point, randomly available pseudopotentials. It runs smoothly on a 2007 vintage desktop PC. On Mon, Jul 18, 2016 at 5:40 PM, Mofrad, Amir Mehdi (MU-Student)
