SUMMARY:A Brief History of Time(keeping): Metrology\, quantum simulati
 on\, and tests of relativity with optical lattice clocks\, Physics Dep
 artment Colloquium\, Shimon Kolkowitz\, UW-Madison
DESCRIPTION:Optical lattice clocks (OLCs) are now the most stable and 
 accurate timekeepers in the world\, with fractional accuracies equival
 ent to neither losing nor gaining a second over the entire age of the 
 universe. This unprecedented level of metrological precision offers se
 nsitivity to new quantum\, many-body\, and fundamental physics effects
 \, opening the door to exciting and unusual applications. This talk wi
 ll provide an introduction to how and why time is measured\, with an e
 mphasis on OLCs and their applications. I will discuss recent progress
  on pushing OLCs to even greater levels of precision\, as well as pros
 pects for future improvement. I also will present results from a recen
 t experiment in which we harnessed the precision of an OLC to simulate
  complex condensed matter phenomena. Finally\, I will give a brief ove
 rview of emerging applications of OLCs\, including research taking pla
 ce here at UW-Madison into using clocks for gravitational wave detecti
 on\, tests of general relativity\, and searches for physics beyond the
  Standard Model.
