Dear developer,

I am writing to seek your advice regarding the methodology for obtaining k point-dependent scattering rates, similar to the data presented in the attached figure.

I have seen plots that display the scattering rate as a function of kx and ky, including data points at negative k-coordinates.

Could you please provide some insight into how this is typically achieved?
.

Best regards,

Hello Donglin Guo,

To compute electron scattering rates, you can compute the imaginary part of the electron self-energy by using the flag 'elecselfen = .true.' and then plot the obtained result (from file linewidth.elself.XXX.XXXK). You can provide any k - grid that you want, but if you just use the variables nkf1, nkf2, nkf3 you will be able to obtain the plot that you want, but the BZ will be shifted w.r.t. the plots you provide (but you can recreate it by pasting the translated copies together).

Best,

Nina.
