Bad Honnef Physics School on «Axions and WISPs»

Targeted to PhD students or young postdocs working on, or with an interest in, axion research. The school aims at providing the foundations of this emerging field, or rounding the overview for those already engaged in aspects of axion research, experimentally or in theory.

It will take place from 2 to 7 August 2020, at the Physikzentrum Bad Honnef, near Bonn and Cologne, Germany. The 200€ fee includes full board and lodging.

Jan Schütte-Enge, «Axion dark matter direct detection: Present and Future» 🗓 🗺

Axions are hypothetical particles introduced to solve the strong CP problem of the Standard Model. In addition axions can resolve the dark matter mystery. In this talk I will first discuss the interesting axion mass ranges which current and future direct detection experiments are targeting. I will then focus on two different detection techniques for dark matter axions. First I will discuss open axion haloscopes, such as dish antennas and dielectric haloscopes. We developed two calculation techniques to compute the fields in open axion haloscopes explicitly in 3D. These 3D techniques are needed for a reliable sensitivity estimate. I show how one can use our methods to calculate axion velocity effects and the influence of several experimental imperfections. The second part of my talk deals with axions that are realized in condensed matter systems. I will first outline an idea how one can detect them. Finally I discuss how axions, that are realized in condensed matter systems, can be used to detect dark matter axions
