Quartic interaction

In quantum field theory, a quartic interaction or φ4 theory is a type of self-interaction of a scalar field. Other types of quartic interactions may be found under the topic of four-fermion interactions. A classical free scalar field φ {\displaystyle \varphi } satisfies the Klein–Gordon equation. If a scalar field is denoted φ {\displaystyle \varphi }…
