An integrated vacuum chamber aligns the MOT, Zeeman slower, and optical lattice to shrink optical lattice clocks for transport.
Band-aligned core-shell particles use a chalcogenide perovskite shell to boost absorbance while preserving emission efficiency and durability.
A chalcogenide perovskite shell boosts excitation-light absorbance while core-shell band alignment creates a Stokes shift that suppresses reabsorption losses.
