Source field: Art, Effective action, mean field approximation, and vertex functions & Source theory for fields

In theoretical physics, a source is an abstract concept, developed by Julian Schwinger, motivated by the physical effects of surrounding particles involved in creating or destroying another particle. So, one can perceive sources as the origin of the physical properties carried by the created or destroyed particle, and thus one can use this concept to…
