Coulomb potential in 2D materials in Eliashberg equation

Post by dinesh169 »

Hello Everyone,

I am using EPW4.0 and I want to ask about the Eliashberg equation. My equation references are from PRB 87 024505 2013.

In equation 11 of above paper, for Coulomb self-energy is the Coulomb potential treated differently for 3D and 2D case? I see only system_2D flag which does not give much information.
Could you please clarify this?
Best wishes,

Hi,

In the EPW implementation of the Eliashberg equations the Coulomb potential only enters as a parameter (same for any dimension).
