The scope of the dark matter problem is profound, with 85% of all matter existing in some unknown form. In the case of the axion, the challenge is compounded by the fact that the parameter space is largely unexplored. The Axion Dark Matter eXperiment (ADMX) and other resonant searches are tackling this problem by searching for axions using a microwave cavity in a magnetic field. We report on...
The MAgnetized Disc And Mirror Axion eXperiment is designed to search for dark matter axions in the mass range of 40 to 400 µeV, a range previously inaccessible by other experiments. This mass range is favored by models in which the PQ symmetry is broken after inflation. The required sensitivity is reached in MADMAX by applying the dielectric haloscope approach, exploiting the axion to photon...
We revisit models of quark matter as possible candidates for dark matter. In these models, dark matter may consist of compact composite objects of dense quark (or antiquark) matter which we refer to as the quark nuggets (QN). We focus on the properties of the electron (or positron) cloud around the QN core, because it may play a crucial role in dark matter detection experiments. In particular,...
