Idea

For electromagnetism the Lorenz gauge condition is one possible gauge fixing condition: It requests that the divergence of the gauge potential AA differential 1-form vanishes: dA=0d \star A = 0.

On Minkowski spacetime in standard coordinates this is the condition μA μ=0\partial_\mu A^\mu = 0 (using Einstein summation convention).

In BV-BRST formalism this gauge (and its variants) is implement by introducing the auxiliary “Nakanishi-Lautrup field” together with its “antighost field”, see at quantization of Yang-Mills theory.
