Atoms in a Row: A New Way to Control Light ⚡ экспресс
Original: "Programmable few-atom Bragg scattering and ground-state cooling in a cavity"
Physicists arranged single atoms into a tidy chain, transforming them into a comb for light waves.

Scientists lined up atoms using laser tweezers and made light reflect off them like a mirror. As they added more atoms, the beam got narrower. Now we can design custom quantum circuits.
🎯 Bragg scattering is typically seen in crystals with billions of atoms; here, for the first time, physicists observed it from a chain of just a few atoms, adding them one at a time.
2d \sin\theta = n\lambda
d — distance between atoms, θ — reflection angle, n — integer, λ — wavelength of light
