Professor Morr's research in theoretical condensed matter physics focuses on the abundance of interesting phenomena in strongly correlated electron systems. He has worked on a wide range of topics, ranging from quantum phase transitions, and optical and electronic properties of magnetic systems to the interplay of magnetism and superconductivity and related resonance phenomena. He has developed a series of theoretical models to explain the results of nuclear-magnetic resonance, angle-resolved photoemission, tunnelling spectroscopy, Raman spectroscopy, and neutron scattering experiments. Among his more recent work is the prediction of an unconventional, current-carrying phase in the pseudo-gap regime of the high-temperature superconductors. He has shown that the existence of a magnetic resonance peak in Sr2RuO4 is tied to the symmetry of its superconducting state. Professor Morr's recent work has also addressed the effects of impurities in magnetic systems and superconductors, as well as quantum interference effects between impurities.
