Generation of the file polarization in Real time approach to linear response

[Moatassim]

Dear all,

I do a simulation in real time. I followed the tutorial based on the Berry Phase (http://www.yambo-code.org/wiki/index.ph ... seApproach) after running the command yambo_nl -u I got this input

nloptics # [R NL] Non-linear optics
% NLBands
1 | 30 | # [NL] Bands
%
NLverbosity= "low" # [NL] Verbosity level (low | high)
NLtime=-1.000000 fs # [NL] Simulation Time
NLCorrelation= "IPA" # [NL] Correlation ("IPA/HARTREE/TDDFT/LRC/LRW/JGM/SEX")
NLLrcAlpha= 0.000000 # [NL] Long Range Correction
% NLEnRange
0.200000 | 8.000000 | eV # [NL] Energy range
%
NLEnSteps= 80 # [NL] Energy steps
NLDamping= 0.200000 eV # [NL] Damping
NLGvecs= 17797 RL # [NL] Number of G vectors in NL dynamics for Hartree/TDDFT
% ExtF_Dir
1.000000 | 0.000000 | 0.000000 | # [NL ExtF] Versor
%

1=> The input dont mention the type of the extF should I add it manually ?

2 => After runnig the command yambo_nl the calcul finish and the code generate just the r_nloptics file. The file polarization is not generated

Thank you
Best regard

Dear Moatassim

first of all please add your affiliation to the post.

Regarding the type of external field, by default is a sinusoidal,
but you can change it by adding the verbosity in the input

Code: Select all

yambo_nl -u -V nl

in order to generate the polarization file, just change the output verbosity

Code: Select all

 NLverbosity= "high" 

best regards
Claudio
