发帖数: 3142 | 1 I find that some book e.g. Many-body theory of solids by John C. Inkson P145
says that :" By analogy with the classical polarization, we define a
polarization
propagator through the relationship ... ε=1-vP" , where ε is the
dielectronic response function, and v is the bare Coulomb potential.
I do not remember such relationship in electrodynamics. Can anybody remind
me of it?
In fact, on the next page in the book, I find a new relationship i.e. P=δρ
/δV， where V is the total potential instead of |
