Abstract: We study the Dirac equation for neutral particles with a magnetic moment in the field of an ultrashort electromagnetic pulse. The pulse is modeled as a delta-distribution, concentrated on a null (i.e. lightlike) hyperplane. We show that the solutions can be obtained by "gluing" free solutions along the pulse and derive corresponding matching conditions. For the special case of a homogeneous electromagnetic pulse, i.e. constant field strength, we explicitly calculate the change in the spin orientation. This is joint work with Peter C. Aichelburg and Herbert Balasin.
