SUMMARY:From the beginning of the universe to the theory of everything: A 
 brief history of Quantum Field Theory. (Field theory in Surface Physics se
 ries 1) - Min Lin\, Cavedish Laboratory\, University of Cambridge

DESCRIPTION:Quantum Field Theory (QFT) stands as one of the most successfu
 l frameworks in modern physics\, with more than thirty Nobel Prizes medals
  in Physics awarded for discoveries directly or indirectly related to it. 
 It combines quantum mechanics and special relativity into a single consist
 ent framework. Within the framework of the Standard Model\, QFT unifies th
 e three fundamental forces — electromagnetic\, weak\, and strong interac
 tions — forming what is often regarded as an almost complete theory of a
 ll known phenomena except gravity.\n\nBeyond being the foundation of eleme
 ntary particle physics\, QFT also offers powerful tools for understanding 
 many phenomena in surface physics — such as quantum diffusion in open qu
 antum systems\, phonon lifetimes\, and frequency shifts.\n\nThis seminar s
 erves as both an introduction and a motivation for the subsequent talks in
  this series\, including the more technical presentations by other group m
 embers in the coming weeks. A basic familiarity with quantum mechanics and
  the Euler–Lagrange formalism is assumed.
