SUMMARY:Tabletop to Telescope: Unraveling the Mystery of Dark Matter\,
  Theory Seminar (High Energy/Cosmology)\, Tanner Trickle\, Fermilab
DESCRIPTION:Recent years have seen a dramatic expansion in ideas to se
 arch for dark matter beyond the WIMP paradigm. In this talk we'll disc
 uss a diverse range of new approaches\, starting with small-scale tabl
 etop experiments. These experiments target dark matter particles far l
 ighter than WIMPs using innovative ideas from condensed matter physics
  and quantum sensing. New calculations have transformed our understand
 ing of how dark matter can interact with electrons and are essential f
 or current experimental efforts. Additionally\, we'll explore how coll
 ective excitations\, e.g.\, phonons and magnons\, can revolutionize th
 e way we search for dark matter. Complementing these tabletop experime
 nts\, pulsar timing arrays are exceptionally sensitive to new physics 
 on galactic scales. While their primary purpose is to detect stochasti
 c gravitational wave backgrounds\, we'll show how their extraordinary 
 precision can be leveraged to hunt for both the lightest\, and heavies
 t\, dark matter candidates.
