A chain of strontium atoms (orange) held in place, with the evenly spaced lines above representing the energy ladder.

Researchers used a strontium-atom quantum simulator to measure an energy-level structure predicted in 1984 and test conformal ...

Chains of up to 35 strontium atoms, each held in place by a tightly focused laser beam, have given Caltech physicists the ...

Researchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging laser-trapped atoms into a quantum simulator, they recreated two different ...
