Optically Pumped Atoms

William Happer, Chairman of the Marshall Institute and professor in the Department of Physics at Princeton University, is a specialist in modern optics, optical and radiofrequency spectroscopy of atoms and molecules, and spin-polarized atoms and nuclei. From 1991 to 1993, he served as Director of Energy Research in the Department of Energy and on his return to Princeton, he was named Eugene Higgins Professor of Physics and Chair of the University Research Board.

Yuan-Yu Jau obtained his Ph.D from Princeton University and continued to work with Professor Happer as a research associate and the Instructor in Physics. Dr. Jau is especially interested in AMO physics with specialty of atomic vapor-cell experiments and computer simulations of optically-pumped atomic systems.
