Dr. Jonathan Wrubel joined the faculty in 2012. His research is in the field of ultracold atomic physics and Bose-Einstein condensates (BECs). Besides his research, he is also keenly interested in issues of science and faith. Prior to joining the faculty at Creighton, Dr. Wrubel was a National Research Council Postdoctoral Fellow with the Joint Quantum Institute at the National Institute of Standards and Technology and the University of Maryland. From 2006-2009 he was a postdoctoral fellow with Harvard University as part of a collaboration seeking to produce, trap and study anti-hydrogen (the anti-matter opposite of the hydrogen atom).
Research Focus
I study the magnetic interactions between potassium-41 atoms at temperatures approaching absolute zero. I am primarily interested in studying how magnetism manifests itself when these ultracold atoms behave quantum-mechanically (i.e. like waves instead of particles).
