Atomic and molecular physics

Atomic and molecular physics it the study of the properties, dynamics and interactions of the basic (but not fundamental) building blocks of matter. A crucial component of this is understanding the behaviour of the electrons that surround the atomic nucleus; these dynamics dominate the way atoms and molecules interact with their environment.

Ultracold atoms serve as ideal systems for precise studies of light-matter interaction. The authors report on absolute strong-field ionization probabilities of rubidium atoms exposed to femtosecond laser pulses and show that Ab-initio theory is in perfect agreement with the data at Keldysh parameters near unity.
