SUMMARY:Modified gravity and the atomic world - Benjamin Elder\, Imperial

DESCRIPTION:The existence of dark energy and dark matter hint that there i
 s more to gravity than meets the eye.  A wide range of new theories\, exh
 ibiting a new scalar particle with a property called screening\, indicate 
 small-scale tests as the most promising route towards detection of new par
 ticles.  Atomic physics is especially promising.  I will discuss how pai
 rs of atomic clocks are capable of searching for equivalence-principle vio
 lating scalar couplings to Standard Model particles\, which hold the poten
 tial to detect quintessence\, ultralight dark matter\, and modified gravit
 y.  Similarly\, atom interferometry and atomic spectroscopy provide a win
 dow to detect new forces associated with new screened scalars as well.
