Presentation
We present here a modification of the spherical reflector approach
proposed for broadband searches for axion dark matter. The new concept
foresees the use of a permanently magnetized surface ({\em magnetized
converter}) employed for axion/ALP$-$photon conversion. The magnetized
converter comprises a two-dimensional Halbach array providing a
sufficiently homogeneous magnetic field with a...

Presentation
Axion-like particles (ALP), produced via the misalignment mechanism are interesting candidates for cold dark matter, both from the theoretical as well as the experimental perspective. The standard potential of ALPs is periodic and bounded from above.
Recently interest has grown towards situations where the periodicity is broken, giving rise to a potential with many non-degenerate...

Presentation
ALPS II is a light shining through a wall style experiment that will use optical cavities to resonantly enhance the coupling between photons and axion-like particles in the mass range below 1 meV. In the last year there has been significant experimental progress in the development of the optical system and the single photon detection schemes, as well as progress related to the preparation of...

Presentation
Well-motivated extensions of the standard model predict ultra-light and
fundamental pseudo-scalar particles (e.g., axions or axion-like particles: ALPs). Similarly to the Primakoff-effect for axions, ALPs can mix with photons and consequently
be searched for in laboratory experiments and with astrophysical observations. Here,
we search for energy-dependent modulations of high-energy...
