摘要:

A formula that relates the imaginary part of the proper self‐energy and the proper vertex part can be derived from the finite temperature generalized Ward‐Takahashi relation. Using the formula, the effects of the electron‐electron Coulomb interaction on the lifetime of the electron quasi‐particles can be calculated within the well‐established RPA scheme. © 2004 American Institute of Physics
