Axions (and axion-like particles) produced by the vacuum realignment
mechanism in the early universe form a highly degenerate Bose gas
and are a cold dark matter candidate. Dark matter axions thermalize as a result of their gravitational self-interactions when the photon temperature reaches approximately 500 eV. When thermalizing, the axion fluid undergoes Bose-Einstein condensation, a...

In this talk, we will report the results of our direct search for sub-GeV dark photons (A') which might be produced in the reaction
e Z -> e Z A' via kinetic mixing with photons by 100 GeV electrons incident on an active target in the NA64 experiment at the CERN SPS. The A's would decay invisibly into dark matter particles resulting in events with large missing energy. No evidence for...

Presentation
We propose a new table-top experimental configuration for the direct detection of dark matter axions.
Different from most experimental setups found in literature on direct dark matter axion detection, which relies on $\dot{\theta}$, we found that our system is in principle sensitive to a static theta as a result of the nontrivial topological features of the Maxwell system. We explain some...

Dark matter axions may be detected by their resonant conversion to photons in a tunable microwave cavity permeated by a strong magnetic field. This talk will give an overview of the design and operational experience of HAYSTAC (Haloscope At Yale Sensitive to Axion CDM), which incorporates a dilution refrigerator and Josephson parametric amplifier and has thus achieved a system equivalent noise...
