DESCRIPTION:Speakers: Gilad Perez (Weizmann Institute)\n\nAfter a brief in
 troduction to ultralight dark matter (UDM)\, we will review the current st
 atus of experimental searches for these candidates. In particular\, we wil
 l explain why modern precision clocks provide powerful probes of UDM. We w
 ill discuss existing and newly proposed well-motivated models of UDM and a
 rgue that they share a common feature: their dominant coupling is often to
  the QCD and nuclear sectors.\nThis is especially timely\, as we are curre
 ntly witnessing a revolution in the field. Recently\, laser excitation of 
 the Th-229 nuclear transition with an effective precision of 10^(−13) ha
 s been achieved. As we will show\, these advances are already probing prev
 iously unexplored regions of parameter space. Moreover\, a Th-based nuclea
 r clock could potentially improve the sensitivity to dark matter and other
  new physics by up to ten orders of magnitude. We will also qualify to wha
 t extent such enhancement estimates can be trusted\, and demonstrate the d
 ramatic implications for fundamental physics leading to thorium supremacy.
