ЧТО ОЗНАЧАЕТ СЛОВО QUANTUM FIELD THEORY
Квантовая теория поля
В теоретической физике квантовая теория поля является теоретической основой построения квантовомеханических моделей субатомных частиц в физике частиц и квазичастицах в физике конденсированных сред. QFT рассматривает частицы как возбужденные состояния лежащего в основе физического поля, поэтому они называются квантами поля. Например, квантовая электродинамика имеет одно электронное поле и одно фотонное поле; квантовая хромодинамика имеет одно поле для каждого типа кварка; и в конденсированном веществе имеется поле атомного смещения, которое приводит к возникновению фононных частиц. Эдвард Виттен описывает QFT как «безусловно» самую сложную теорию в современной физике. В QFT квантовомеханические взаимодействия между частицами описываются условиями взаимодействия между соответствующими подстилающими полями. Условия взаимодействия QFT схожи по духу с соотношениями между зарядами с электрическим и магнитным полями в уравнениях Максвелла. Однако, в отличие от классических полей теории Максвелла, поля в QFT обычно существуют в квантовых суперпозициях состояний и подчиняются законам квантовой механики.
Значение слова quantum field theory в словаре английский языка
Определение квантовой теории поля в словаре - квантово-механическая теория, связанная с элементарными частицами, которые представлены полями, чьи нормальные моды колебаний квантуются.
ЦИТАТЫ СО СЛОВОМ «QUANTUM FIELD THEORY»
Известные цитаты и высказывания со словом
quantum field theory.
When I was at Berkeley, the framework of quantum field theory could calculate the dynamics of electromagnetism. It could roughly describe the motion of the weak nuclear force, radiation. But it hit a brick wall with the strong interaction, the binding force.
I had set out to disprove quantum field theory - and the opposite occurred! I was shocked.
Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.

The book concludes with a brief survey of "topological" objects in field theory and, new to this edition, a chapter devoted to supersymmetry. Graduate students in particle physics and high energy physics will benefit from this book.
Problems are provided at the end of each chapter. New to this edition: Five new chapters, giving an introduction to quantum chromodynamics and the methods used to understand it: in particular, path integrals and the renormalization group.
