DESCRIPTION:Speakers: Lars von der Wense (JGU Mainz)\n\nThe year 2024 was 
 a breakthrough year in 229Th-related research\, with three experiments rep
 orting success in the laser spectroscopy of the lowest nuclear excited sta
 te of 229Th. The highest accuracy was achieved at JILA via direct frequenc
 y comb spectroscopy of this\, previously elusive\, nuclear state. This suc
 cess is the result of several decades of effort to precisely determine the
  transition energy and a first step towards nuclear precision spectroscopy
  and the development of a nuclear frequency standard of extremely high acc
 uracy.Applications for dark matter detection as well as the search for tim
 e variations of fundamental constants appear to be in reach.\nIn this talk
  I will provide an overview over the history of 229Th that has culminated 
 in this success. Further\, I will discuss the remaining efforts and challe
 nges. Finally\, I will introduce the investigations underway within the fr
 amework of the BMFTR-funded project “NuQuant”.\n \n \n
