Hello all,
We know that (E,p) are the components of a four vector and it is called the four-momentum.
Likewise (V,A) are the components of a four-vector and it is called the four-potential.
But it seems that the four-vector with p-eA is the most important one, yet I don't recall every learning it's name. Does it have a name?
