But Schwinger followed the diﬀerential route, and starting in early 1950 began a new, his third, formulation of quantum electrodynamics, based on a variational approach. This was ﬁrst published in 1951 [Schwinger 1951b]. A bit later he started developing a new formulation of quantum ...

WebYou can do the same with a third-order (or "three-dimensional") tensor: c = ∑ i j k a i j b i d j e k. This is now linear in all three vectors. Or you do such: c i j = ∑ k a i j k e k, thus getting a second-order tensor, which we usually call a matrix. The order of a tensor doesn't refer to the amount of entrys. Share.

The Schwinger effect is a predicted physical phenomenon whereby matter is created by a strong electric field. It is also referred to as the Sauter–Schwinger effect, Schwinger mechanism, or Schwinger pair production. It is a prediction of quantum electrodynamics (QED) in which electron–positron pairs are spontaneously created in the presence of an electric field, thereby causing the … WebMar 25, 2024 · We develop a system of equations for the propagators and three-point functions of the $$\\phi ^3$$ ϕ 3 quantum field theory in six dimensions.
