Before he developed the atomic bomb, J. Robert Oppenheimer's early work revolutionized the field of quantum chemistry – and his theory is still used today

In 1927, Oppenheimer published a paper called “On the Quantum Theory of Molecules” with his research adviser Max Born. This paper outlined what is commonly referred to as the Born-Oppenheimer ...

Innovative optical atomic clock could combine single-ion accuracy with multi-ion stability

For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more ...
