Research Description

The goal of Dr. Abraham's research program is to investigate ultracold atoms and molecules. They use a variety of lasers, in addition to magnetic and electric fields, to cool atoms and molecules to nearly absolute zero (tens of microKelvin). At these temperatures, thee wave-like nature of matter is enhanced allowing studies of their exotic, quantum-mechanical nature.

Dr. Abraham currently studies Feshbach Optimized photoassociation, where ultracold atoms undergo a collisional resonance. During the resonant collision, a photon binds them together into an excited-state molecule, allowing molecular spectroscopy inaccessible with any other method.

Another project uses the ultracold atoms as a non-linear medium for quantum optics experiment studying electromagnetically induced transparency (EIT), a common method of precision measurement. The research explores EIT, using lasers with orbital angular momentum.
