- Light Dark Matter: Collective Effects in the Lab and in Stars
- Time: 2:00 pm - 3:00 pm
- Place: virtual - Join Zoom Meeting
- Speaker: Edoardo Vitagliano, UCLA
- Abstract: Light dark matter candidates, such as axions and hidden photons, call for new ideas in direct detection. I discuss the recently proposed strategy of searching for e.g. axions using tunable cryogenic plasmas. The plasma haloscope enables resonant conversion by matching the axion mass to a plasma frequency, therefore converting axions to plasmons. Metamaterials are promising candidates, as the plasma frequency can be tuned. Besides axions, other dark matter candidates, such as hidden photons and scalars, can be successfully targeted with a plasma haloscope. The same collective effects are relevant for light dark matter production in the Sun and in other stars.
