Abstract
A panoramic view is given of the applications of QFT to diverse areas of physics, beginning with the concepts of QED Vacuum as well as of electron self-energy and renormalization. The related concepts of the degenerate vacuum, spontaneous symmetry breaking (SSB)and Nambu-Goldstone bosons, together with their applications to condensed matter physics and quasi particles are outlined. The possibilities of application to life sciences are also examined. Finally the alternative method of Path integrals for introducing QFT is briefly indicated.
