The invariance of electric and magnetic fields and electrodynamic interactions under gauge transformations.
(physics)
The invariance of any field theory under gauge transformations.
(quantum mechanics)
An invariance of a Lagrangian based on an internal gauge group, such as U(1) for electromagnetism or U(1) × SU(2) for the Weinberg-Salam unified model of weak and electromagnetic interactions.

Introduces the gauge invariance property of acoustic equation of motion, with applications in the elastic constants of isotropic solids, time reversal acoustics, negative refraction, double negative acoustical metamaterial and acoustical cloaking.
Perhaps it is not quite an exaggeration to remark here that most subsequent developments in both elementary particle physics and also hadron physics were advanced by YangMills' effort to generalize the gauge invariance [8].
And in this regards, gauge invariance of superconductivity becomes chiral invariance of the strong interaction.
k] is an interaction field, then it should result from the gauge invariance principle [5].
An alternative modification of U(I) gauge invariance explored in ([21], where we demand that the Lagrangian density be invariant under a time-local (rather than space-local) U(1) gauge transformation [psi] [right arrow] [psi]' = U[psi] with U being time-dependent (rather than space-dependent), generated a scalar spin0 field (rather than a 3-vector spin1 field) which we identify as the gravitational field (instead of the magnetic field).
Also by the gauge invariance property the factor [e.
This means that the gauge fixing condition has already fixed the gauge that the degenerate degree of freedom of gauge invariance has been eliminated so that we can carry out computation.
The role of gauge invariance in physics is analogous to an equivalence class in mathematics.
I think that the treatment of the scalar multiplet actions in the present work may contain clues to supergravity, both considering the extra gauge invariances and the extra factors of [lambda] in the action.
A failure of gauge invariance may also appear in different contexts, which are introduced in the next sections.
