Exc-Ph Linewidths at finite q

Post by rishabhsrsw7 » Sun Jul 19, 2026 4:43 pm

Dear all,

Last year while trying to calculate the exc-ph linewidths I used yambo_ph which generated multiple files of the sort:

Code: Select all

#     |q| (a.u.)         e1                 e2                 e3                 e4                 e5                q_x (rlu)          q_y (rlu)          q_z (rlu)

      0.667863312E-1     0.292935051E-1     0.295540829E-1     0.206869579E-1     0.205167614E-1     0.213172212E-2      0.00000000        0.555555556E-1      0.00000000   
      0.667863312E-1     0.292934572E-1     0.295540605E-1     0.206012734E-1     0.206027546E-1     0.213149538E-2    -0.555555556E-1    -0.277777778E-1      0.00000000   
      0.667863312E-1     0.292935060E-1     0.295541221E-1     0.206037327E-1     0.206001752E-1     0.213152509E-2     0.555555556E-1    -0.277777778E-1      0.00000000   
      .........			.......				......				....				......			......				.....			......			.....
Right now I forget how I did this, and the linewidth tutorial is absent under https://wiki.yambo-code.eu/wiki/index.p ... minescence.

Is there a way someone can help me with this? Or is there a way to generate this with yambopy?
