Question

What is screened interaction in condensed matter physics?

Answer 1

Explanation:

In the random phase approximation we obtain that the Coulomb interaction between charges is replaced by an effective interaction V(r)=1re−kDr

Answer 2

it's the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they interact. Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
