Features of screening and confinement are studied for the coupling of axialtorsion fields with photons in the presence of an external electromagneticfield. To this end we compute the static quantum potential. Our discussion iscarried out using the gauge-invariant but path-dependent variables formalismwhich is alternative to the Wilson loop approach. Our results show that, in thecase of a constant electric field strength expectation value, the staticpotential remains Coulombic, while in the case of a constant magnetic fieldstrength expectation value the potential energy is the sum of a Yukawa and alinear potential, leading to the confinement of static probe charges.
