Field theory (sociology) - Wikipedia
In sociology, field theory examines how individuals construct social fields, and how they are affected by such fields.Social fields are environments in which competition between individuals and between groups takes place, such as markets, academic disciplines, musical genres, etc.. Fields feature different positions that social actors can occupy. The dominant players in the field, called the ...

Lewin's Field Theory (Social Development) - Practical Psychology
Nov 13, 2023Field Theory in Practice: Lewin believed that to understand and predict behavior, one must consider the totality of the life space and not just isolated factors. This holistic approach was revolutionary at the time and has since influenced various areas of psychology, especially in understanding group dynamics and organizational change.

Quantum Field Theory - Stanford Encyclopedia of Philosophy
Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. It is also a framework used in other areas of theoretical physics, such as condensed matter physics and statistical mechanics. In a rather informal sense QFT is the extension of quantum mechanics (QM), dealing with particles ...

Jan 11, 2024quantum field theory, body of physical principles combining the elements of quantum mechanics with those of relativity to explain the behaviour of subatomic particles and their interactions via a variety of force fields. Two examples of modern quantum field theories are quantum electrodynamics, describing the interaction of electrically charged particles and the electromagnetic force, and ...

Field theory - Wikipedia
Field theory (physics), a physical theory which employs fields in the physical sense, consisting of three types: Classical field theory, the theory and dynamics of classical fields. Quantum field theory, the theory of quantum mechanical fields. Statistical field theory, the theory of critical phase transitions. Grand unified theory.

Classical field theory - Wikipedia
A classical field theory is a Physical theory that predicts how one or more fields in physics interact with matter through field equations, without considering effects of quantization; theories that incorporate quantum mechanics are called quantum field theories.In most contexts, 'classical field theory' is specifically intended to describe electromagnetism and gravitation, two of the ...

Effective field theory - Wikipedia
In physics, an effective field theory is a type of approximation, or effective theory, for an underlying physical theory, such as a quantum field theory or a statistical mechanics model. An effective field theory includes the appropriate degrees of freedom to describe physical phenomena occurring at a chosen length scale or energy scale, while ignoring substructure and degrees of freedom at ...

Quantum field theory - Wikipedia
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics.: xi 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 quantum levels) of their ...

Unified field theory - Wikipedia
Unified field theory. In physics, a unified field theory ( UFT) is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a pair of physical and virtual fields. According to modern discoveries in physics, forces are not transmitted directly between interacting ...

标量场理论 Scalar Field Theory - Academic Accelerator
然而，标量量子场出现在许多物理现象的有效场论描述中。一个例子是 pion，它实际上是一个伪标量。由于标量场不涉及偏振复杂性，因此通常最容易通过第二次量化来评估。因此，标量场理论经常被用来引入新的概念和技术。

Scalar field theory - Wikipedia
In theoretical physics, scalar field theory can refer to a relativistically invariant classical or quantum theory of scalar fields.A scalar field is invariant under any Lorentz transformation.. The only fundamental scalar quantum field that has been observed in nature is the Higgs field.However, scalar quantum fields feature in the effective field theory descriptions of many physical phenomena.
