QUÉ SIGNIFICA QUANTUM FIELD THEORY EN INGLÉS
Teoría del campo cuántico
En física teórica, la teoría cuántica de campos es un marco teórico para construir modelos mecánicos cuánticos de partículas subatómicas en física de partículas y cuasipartidas en física de materia condensada. Un QFT trata las partículas como estados excitados de un campo físico subyacente, por lo que se llaman cuantos de campo. Por ejemplo, la electrodinámica cuántica tiene un campo de electrones y un campo de fotones; La cromodinámica cuántica tiene un campo para cada tipo de quark; Y, en materia condensada, hay un campo de desplazamiento atómico que da lugar a partículas de fonón. Edward Witten describe a QFT como "de lejos" la teoría más difícil de la física moderna. En QFT, las interacciones mecánicas cuánticas entre partículas se describen por términos de interacción entre los correspondientes campos subyacentes. Los términos de interacción QFT son similares en espíritu a aquellos entre cargas con campos eléctricos y magnéticos en las ecuaciones de Maxwell. Sin embargo, a diferencia de los campos clásicos de la teoría de Maxwell, los campos en QFT generalmente existen en superposiciones cuánticas de estados y están sujetos a las leyes de la mecánica cuántica.
definición de quantum field theory en el diccionario inglés
La definición de teoría cuántica de campos en el diccionario es teoría mecánica cuántica relacionada con partículas elementales, que están representadas por campos cuyos modos normales de oscilación están cuantificados.

3 CITAS EN INGLÉS CON «QUANTUM FIELD THEORY»
Citas y frases célebres con la palabra
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.
