41. One of the theoretical products of this phase transition was a scalar field called the inflaton field. 42. As long as supersymmetry is unbroken, such scalar fields can take arbitrary values ( they are moduli ). 43. A scalar field source is another scalar field that contributes a term to the ( Lorentz ) Lagrangian: 44. Current algebra . ) A scalar field model encoding chiral symmetry and its breaking is the chiral model. 45. The second equation describes how the stress energy tensor and scalar field \ phi together affect spacetime curvature. 46. The regularization of is also involved in computing the Casimir force for a scalar field in one dimension. 47. A scalar field source is another scalar field that contributes a term to the ( Lorentz ) Lagrangian: 48. Is that a warning to everyone here to not call your bluff on that scalar field theory reference? 49. Lagrangians in quantum field theory for complex scalar fields are often invariant under U ( 1 ) transformations. 50. Scalar fields having only a slight amont of spatial inhomogeneity would be difficult to distinguish from a cosmological constant.
