Eric Braaten
Eric Braaten carried out his graduate work in theoretical high-energy physics at the University of Wisconsin, receiving his Ph.D. in 1981. After postdoctoral positions at University of Florida and Argonne National Laboratory, he took a faculty position at Northwestern University in 1995, where he conducted ground-breaking research on quantum chromodynamics. He moved to Ohio State University in 1995, where he has branched out into the field of ultracold atoms. Dr. Braaten was awarded the Humboldt Research Prize in 2009, and is now visiting the Bethe Center for Theoretical Physics at Bonn University. He continues to work on both low-energy and high-energy problems in elementary particle physics and on both few-body and many-body aspects of ultracold atoms. Dr. Braaten was chosen as a Fellow of the American Physical Society in 2000 and named an Outstanding Referee in 2008.
How the tail wags the dog in ultracold atomic gases
Recent calculations of the properties of ultracold atoms have revealed how two-body interactions at very short distances determine essential properties of many-body systems. Read More »
