rim_cut and rimw

Post by xjxiao » Fri Mar 21, 2025 3:36 pm

Dear all,
When performing BSE (Bethe-Salpeter Equation) calculations in Yambo, in which of the three steps—calculating the static dielectric function, calculating the BSE kernel, and diagonalization—should rim_cut and rimw be applied?
Thanks!

Dear Xiao,

it applies when calculating the BSE kernel, anyway please note that rimw for BSE is experimental, so I suggest you to make appropriate checks.

Best,
Daniele
