LQG: String Theory? - Baez's Page

SUMMARY

The discussion centers on the term "Wilson loops," which are named after Kenneth G. Wilson, a Nobel Prize winner recognized for his contributions to the renormalization group. In 1964, Wilson defined lattice gauge theory and introduced Wilson Lines, which are foundational in quantum field theory. A Wilson Loop is defined as a closed Wilson Line, playing a significant role in the study of gauge theories and string theory.

PREREQUISITES
  • Understanding of lattice gauge theory
  • Familiarity with quantum field theory concepts
  • Knowledge of the renormalization group
  • Basic grasp of Wilson Lines and their applications
NEXT STEPS
  • Research the implications of Wilson Lines in quantum field theory
  • Study the role of the renormalization group in particle physics
  • Explore advanced topics in lattice gauge theory
  • Investigate the applications of Wilson loops in string theory
USEFUL FOR

Physicists, particularly those specializing in quantum field theory and string theory, as well as students and researchers interested in the foundational concepts of gauge theories.

Any idea where the term "Wilson loops" got it's name?
 
From Kenneth G. Wilson, the same man who got the Nobel prize for his work with the renormalization group. Wilson in 1964 defined lattice gauge theory, and in connection with that he invented what are now called Wilson Lines. A Wilson Loop is just a closed Wilson Line.
