SUMMARY:Light Dark Matter: Collective Effects in the Lab and in Stars\
 , Network in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) 
 Seminar\, Edoardo Vitagliano\, UCLA
DESCRIPTION:Light dark matter candidates\, such as axions and hidden p
 hotons\, call for new ideas in direct detection. I discuss the recentl
 y proposed strategy of searching for e.g. axions using tunable cryogen
 ic plasmas. The plasma haloscope enables resonant conversion by matchi
 ng the axion mass to a plasma frequency\, therefore converting axions 
 to plasmons. Metamaterials are promising candidates\, as the plasma fr
 equency 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 ligh
 t dark matter production in the Sun and in other stars.
