AB  - The excitation fields D and H cannot be directly measured and have a gauge freedom. Admitting this freedom opens many possibilities, concerning the axionic response, which have direct application. We show a simple scenario which due to topological reasons is impossible using D and H. It can be used to model periodic lattices which have non zero total charge and show that an evaporated black hold can break charge conservation. We reflect on the nature of a homogeneous axionic response.
