The inverse operator for Rthe operator k̂ does not exist since, for any ψ(x), the primitive function i dx ψ(x) which should give back ψ(x) after the action by −i(d/dx) is defined only up to a constant. The reason is that the constant is an eigenfunction of the operator k̂ corresponding to the eigenv ...

Scalar field theory

In theoretical physics, scalar field theory can refer to a 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. An example is the pion, which is actually a pseudoscalar.Since they do not involve polarization complications, scalar fields are often the easiest to appreciate second quantization through. For this reason, scalar field theories are often used for purposes of introduction of novel concepts and techniques.The signature of the metric employed below is (+, −, −, −).
