What is gauge transformation in electrodynamics?
In other words, a gauge transformation introduces a position- and time-dependent phase-shift, , into the wavefunction. Now, Equation (3.88) is equivalent to Equations (3.76) and (3.87). If we take the expectation values of the latter two equations then we obtain. (3.99)What is the gauge transformation?
A gauge transformation can be broadly defined as any formal, systematic transformation of the potentials that leaves the fields invariant (although in quantum theory it can be perhaps a bit more subtle than that because of the additional degree of freedom represented by the quantum phase).What is gauge transformation equation?
E=?gradV. The zero of the potential is arbitrary. We can add any constant (with the dimensions of potential) to V. For example, if we define V?=V+C where C is a constant (in the sense that it is not a function of x, y, z) then we can still calculate the electric field from E=?gradV?.- As Lorentz transformations act on space-time coordinates, gauge transformations are applied to the gauge field. Placing these two transformations on the same ground means that all quantized field like spin-1/2 and spin-3/2 spinors are functions not only of the coordinates but also of the gauge field components.
