Information Discussion 0 Files Holdings. Series Dover books on physics and chemistry Subject code Particular attention is given to the interaction of charged particles with the electromagnetic field. The treatment throughout the book is relativistic; the author attempts, as much as possible, a coordinate free or covariant form of the equations both for particles and the fields.

A classical field theory is a physical theory that predicts how one or more physical fields interact with matter through field equations. The term 'classical field theory' is commonly reserved for describing those physical theories that describe electromagnetism and gravitation , two of the fundamental forces of nature. Theories that incorporate quantum mechanics are called quantum field theories. A physical field can be thought of as the assignment of a physical quantity at each point of space and time. For example, in a weather forecast, the wind velocity during a day over a country is described by assigning a vector to each point in space. Each vector represents the direction of the movement of air at that point, so the set of all wind vectors in an area at a given point in time constitutes a vector field. As the day progresses, the directions in which the vectors point change as the directions of the wind change.

Classical field theory

In theoretical physics , quantum field theory QFT is a theoretical framework that combines classical field theory , special relativity and quantum mechanics , [1] : xi but not general relativity 's description of gravity. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. QFT treats particles as excited states also called quanta of their underlying quantum fields , which are more fundamental than the particles. Interactions between particles are described by interaction terms in the Lagrangian involving their corresponding quantum fields. Each interaction can be visually represented by Feynman diagrams according to perturbation theory in quantum mechanics.

The two basic and most fundamental concepts of classical atomistic physical theories—in contrast to phenomenological theories like thermodynamics—are that of particle and field. Broadly speaking, this book deals with the interactions of systems consisting of particles and fields and, in particular as a prototype, with the interactions of charged particles with the electromagnetic field. These two concepts or entities are quite distinct in classical theories and they are described by very different mathematical apparatus: on the one hand, space-time points as the positions of the particles; on the other hand, functions of space-time as the field intensity or the potential. Only in relativistic quantum theories do we arrive at a synthesis of these two concepts, namely to attempt to describe everything in terms of fields alone, or in terms of particles alone.
