DESCRIPTION:\nMetastable states in alkaline-earth-like atoms provide a pow
 erful and largely untapped resource for advancing quantum sensing and opti
 cal clock technologies. In particular\, long-lived metastable manifolds en
 able novel cooling\, trapping\, and state-control techniques\, forming a r
 ich toolbox for the development of continuous-operation quantum devices. I
 n this talk\, I will present two distinct Sisyphus cooling schemes that ex
 ploit narrow-line transitions involving metastable states to achieve effic
 ient cooling and enhanced atomic clock performance\, leveraging state-depe
 ndent optical potentials and engineered dissipation pathways beyond conven
 tional limits.I will also report on the latest progress in our ytterbium n
 eutral atom lab at the Institute of Atomic and Molecular Sciences\, includ
 ing recent spectroscopy of previously unexplored transitions\, the develop
 ment of optical system design tools tailored for modular architectures\, a
 nd numerical simulations that guide the implementation of novel cooling st
 rategies in realistic experimental geometries.Together\, these development
 s outline a pathway toward continuous ultracold atomic sources and next-ge
 neration optical clocks\, where metastable-state engineering plays a centr
 al role in overcoming current limitations imposed by dead time and laser-i
 nduced decoherence.\n\n \n\nhttps://indico.phys.nthu.edu.tw/event/189/
