Simulation of axion-electrodynamics for the MADMAX experiment — •Jan Schütte-Engel for the MADMAX collaboration — University of Hamburg, Hamburg, Germany

Axions are hypothetical particles introduced to solve the strong CP problem of the Standard Model. In addition axions can resolve the dark matter mystery. Axions with masses in the range of a few µeV up to a few hundreds of µeV are furthermore motivated by the scenario in which the Peccei-Quinn symmetry is broken after inflation. These motivate the search for axions in direct detection experiments on Earth, and the development of new techniques to become sensitive to this specific axion mass region. The presence of axions modifies the Maxwell equations, which many direct axion search experiments on Earth exploit. In this talk we will discuss the simulation of axion-electrodynamics. The developed formalism is applied to the MADMAX direct detection axion experiment, where diffraction and near field effects can be important loss mechanism.
