Physicists Finally Measure a Long Theorized Molecule Made From Light And Matter

Physicists have just caught light acting the part of ‘glue’ between atoms, in a kind of loosely bonded molecule. “We have succeeded for the first time in polarizing several atoms together in a controlled way, creating a measurable attractive force between them,” says University of Innsbruck physicist Matthias Sonnleitner.
