The Thompson group has figured out how to use magnetic fields to create atomic cowpokes to wrangle a specific single color. The researchers do this with a magnetic field that causes strontium atoms in an optical cavity to stop absorbing light and become transparent to laser light at one specific color. What happens is that the magnetic field creates a transparent window that serves as a gate to let only light of a single frequency pass through.
