WS for low dimentional systems
Posted: Fri Mar 13, 2026 2:52 pm
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
