SUMMARY:Hunting for “fifth forces”\, axions\, and dark matter with
  optomechanical and spin-based sensors \, Physics Department Colloquiu
 m\, Andrew Geraci\, Northwestern
DESCRIPTION:Despite the enormous success of the Standard Model of part
 icle physics\, many basic phenomena around us remain without any expla
 nation\, including the nature of Dark Matter and Dark Energy\, which t
 ogether make up 95 percent of our universe. Complementary to high-ener
 gy particle colliders or large-scale detectors\, a variety of ultra-se
 nsitive tabletop experiments are well-suited to discover a wide range 
 of new phenomena beyond the Standard Model\, where feeble interactions
  require precision measurements rather than high energies.  In this ta
 lk I will describe our experimental efforts using dielectric objects s
 upported by radiation pressure as precision sensors to search for quan
 tum effects related to gravity\, high-frequency gravitational waves\, 
 and Dark Matter. I will also discuss The Axion Resonant InterAction De
 tection Experiment (ARIADNE)\, which aims to detect novel short-range 
 spin-dependent interactions.
