Introduction to Effective Field Theory (eBook, ePUB)

Thinking Effectively about Hierarchies of Scale

• Format: ePub

Produktbeschreibung

Using examples from across the sub-disciplines of physics, this introduction shows why effective field theories are the language in which physical laws are written. The tools of effective field theory are demonstrated using worked examples from areas including particle, nuclear, atomic, condensed matter and gravitational physics. To bring the subject within reach of scientists with a wide variety of backgrounds and interests, there are clear physical explanations, rigorous derivations, and extensive appendices on background material, such as quantum field theory. Starting from undergraduate-level quantum mechanics, the book gets to state-of-the-art calculations using both relativistic and nonrelativistic few-body and many-body examples, and numerous end-of-chapter problems derive classic results not covered in the main text. Graduate students and researchers in particle physics, condensed matter physics, nuclear physics, string theory, and mathematical physics more generally, will find this book ideal for both self-study and for organized courses on effective field theory.

Autorenporträt

C. P. Burgess is a professor at both McMaster University and the Perimeter Institute for Theoretical Physics, and co-author of the book The Standard Model: A Modern Primer. He is a Fellow of the Royal Society of Canada and has been awarded the CAP/CRM medal for Theoretical Physics. After initially learning about effective field theories from his PhD supervisor, Nobel Laureate Steven Weinberg, he is now a world expert on their applications throughout physics.
