WS for low dimentional systems

Dear all,

I am calculating the GW and BSE for a 1D chain system with the x-axis as the periodic direction.
I set up the cut-off for the coulomb interaction using the wigner seitz cut (my cell is orthorhombic).

I was wondering if the RIM procedure is also required for WS, as in the case of Box cut-off.

Best,

Marco

Dear Marco,

in this case the RIM procedure does not apply.

Best,
Daniele
