Web2 is a well-de ned function of ˘ 1 = t, where ˘ 2 stands for any of the points with (˘ 1;˘ 2) 2; we write ˜(t) for this unimodular function. If Eis a closed subset of R and t 0 2E, we say … WebTherefore, a system that can be described by a complex solution to the Klein-Gordon equation also be described by a system of two independent particles with equal mass that have real solutions to the Klein-Klein-Gordon equation. 2.2 Lagrangian Density We have two potential ways to describe this complex system, with †and or with 1 and 2.First,we

The equation was named after the physicists Oskar Klein and Walter Gordon, who in 1926 proposed that it describes relativistic electrons. Vladimir Fock also discovered the equation independently in 1926 slightly after Klein's work, in that Klein's paper was received on 28 April 1926, Fock's paper was received on 30 July 1926 and Gordon's paper on 29 September 1926.

The potential satisfies the boundary condition. provided that the source function is reasonably localized. The … WebIn quantum field theory, correlation functions, often referred to as correlators or Green's functions, are vacuum expectation values of time-ordered products of field operators. They are a key object of study in quantum field theory where they can be used to calculate various observables such as S-matrix elements. how to take your temperature with thermometer
