Calculatind recombination rate/ radioactive lifetime

[Ponnappa]

Dear Yambo Developers and Users,
I am having some issues understanding how to find the recombination rate. As per https://doi.org/10.1103/PhysRevB.100.075135 the radiactive rate for 2D is given by r_s(0) = (e^2*p_s^2)/(\epsilon_0*m^2*c*A*E_s(0)). Here, are the transition dipoles given by p_s = Maximum_Residual_Value*Stength (which are obtained in exc_qpt1_E_sorted file)? Also, what are the units of maximum residual values?

Looking forward for the reply. Thank you in advance.

Dear Ponappa,

In this thread

Dear Daniele,

Thank you for the suggestion, which was helpful. However, I still have some minor doubts regarding the dimension, which I posted in the earlier mentioned thread (viewtopic.php?t=1947). Looking forward for the response for the same.

Dear Ponappa,

I suggest you to write directly to the author of the paper (Maurizia Palummo) mentioning your post in the forum.

Best,

Daniele
