Biography

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 and Scholarship

Research and Scholarship Interests

  • 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).

Current Research Projects

  • Currently we are building an apparatus to detect and study a proposed radio-frequency Fano-Feshbach resonance in potassium-41.

Grant Funding Received

  • Dynamically controlled magnetism in a 41K spinor Bose-Einstein condensate. (2014 Creighton University Summer Research Fellowship, role: P.I.). The goal of this research is to construct a two-dimensional magneto- optical trap, which is a first step in achieving Bose-Einstein condensation. Application: October 31, 2013. Funded: December 11, 2013.
  • Laser-Cooling Atoms: Making the Coldest Stuff in the Universe. (Dr. George F. Haddix President’s Faculty Research Fund, Creighton University, role: P.I.) The goal of this research is to lead two undergraduate students during the summer of 2013 in building two critical components of the Bose-Einstein condensation apparatus. The first is the laser required to cool the atoms, and the second is a wavelength-meter needed to set the laser to the proper wavelength. Application: December 1, 2012. Funded: February 22, 2013.
  • Precision Measurement of a Microwave Fano-Feshbach Resonance in Ultracold 41K Atoms. (Research Corporation for Science Advancement, Cottrell College Science Award, role: P.I., 2015) The goal of this research is to perform a precision measurement of a microwave transition in potassium-41 called a Fano-Feshbach resonance. This measurement would yield new information on the interactions of potassium atoms at ultracold temperatures as well as provide a tool for studying novel quantum phase transitions
