For a theory with a pseudo scalar coupling φFF̃ and in the case that there is a constant electric or magnetic strength expectation value, we compute the interaction potential within the structure of the gauge-invariant but pathdependent variables formalism. While in the case of a constant electric field strength expectation value the static potential remains Coulombic, in the case of a constant ...

The last decades have seen increased interest toward possible adverse effects arising from exposure to intense static magnetic fields. This concern is mainly due to the wider and wider applications of such fields in industry and clinical practice; among them, Magnetic Resonance Imaging (MRI) facilities are the main sources of exposure to static magnetic fields for both general public (patients)...
