Particles are quantized excitations of fields from "summary" of The Quantum Theory of Fields by Steven Weinberg,Weinberg S
Quantum field theory is a theoretical framework that combines the principles of quantum mechanics with the concepts of fields. In this framework, particles are viewed as quantized excitations of these fields. This means that the fields themselves are the fundamental entities, and particles are simply specific manifestations or vibrations of these fields. Each type of particle corresponds to a specific field, which permeates all of spacetime. For example, the electromagnetic field corresponds to photons, the particles that carry the electromagnetic force. Similarly, the electron field corresponds to electrons, the fundamental particles of matter. By quantizing these fields, we can understand the discrete and quantized nature of particle properties, such as energy and momentum. In classical field theory, fields are continuous and can take on any value at each point in spacetime. However, in quantum field theory, these fields are quantized, meaning they can only have certain discrete values. These quantized values correspond ...
