Quartic Interaction
This article refers to a type of self-interaction in scalar field theory, a topic in quantum field theory. Other types of quartic interactions may be found under the topic of four-fermion interactions. A classical free scalar field φ satisfies the Klein-Gordon equation. If a scalar field is denoted φ, a quartic interaction is represented by adding a potential term . The coupling constant λ is dimensionless in 4-dimensional space-time.
This article uses the (+−−−) metric signature for Minkowski space.

Famous quotes containing the word interaction:
“Here is this vast, savage, howling mother of ours, Nature, lying all around, with such beauty, and such affection for her children, as the leopard; and yet we are so early weaned from her breast to society, to that culture which is exclusively an interaction of man on man,—a sort of breeding in and in, which produces at most a merely English nobility, a civilization destined to have a speedy limit.”
—Henry David Thoreau (1817–1862)
