Classical Scalar Field in Four Dimensions
https://quantummechanics.ucsd.
We have developed a covariant classical theory for a scalar field. The Lagrangian density is a Lorentz scalar function. We have included an interaction term to ...
Intuitive explanation for the free field Lagrangian?
https://physics.stackexchange.
For a scalar field, this lagrangian is the simplest one which is invariant under Lorentz transformations. There is no other explanations for ...
Lagrangian (field theory)

In Lagrangian field theory, the Lagrangian as a function of generalized coordinates ... The Lagrangian for a scalar field moving in a potential V ( ϕ ) ...
Lagrangian Field Theory
https://www.sas.rochester.edu
We consider each field to be a scalar field on four-dimensional spacetime. We assume that the system can be described by a Lagrangian density.
Lagrangian formalism for fields

For quantum mechanics, we want a Lagrangian that will yield the Klein–Gordon equation. If φ is a single real scalar field, then the required Lagrangian is. L ...
Scalar field theory
https://en.wikipedia.org
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.
The Lagrangian in Scalar Field Theory
https://physics.stackexchange.
A scalar field and the derivatives both have dimension of [mass]2 and the Lagrangian density has dimension [mass]4, so c should be dimensionless ...
