@informaq.bsky.socialDemonstrated Aubry-André localization in bichromatic optical lattices to suppress tunneling, achieving 100-fold improvement in atomic coherence times—enabling precision optical lattice clocks for future space-based applications.
@informaq.bsky.socialTrapped calcium ion clock achieves 1.5×10⁻¹⁵ fractional frequency uncertainty via GNSS satellite link to international time standard. Includes refined measurement of D₅/₂ Landé g-factor accounting for ac Zeeman shifts in ion trap electrodes.
