The John Simon Guggenheim Memorial Foundation has awarded 2015 Guggenheim fellowships to two University of Illinois faculty members: Wendy K. Tam Cho, professor of political science and of statistics, and Philip W. Phillips, professor of physics. Cho and Phillips are among 175 fellows chosen for "prior achievement and exceptional promise" from a group of more than 3,100 applying scholars, artists and scientists. To provide creative freedom, fellows are awarded unrestricted grants that they can apply to work of their choosing.
Phillips works in theoretical condensed matter physics. He has developed various models of how electrons travel through superconductors containing copper and iron and how electrons interact at temperatures near absolute zero. He is known for devising the random dimer model, a 1-dimensional model that conducts electricity, thereby providing a concrete counterexample to Anderson's localization theorem, and for developing the concept of Mottness, in which strong electron interactions lead to a breakdown on the particle concept in high-temperature superconductors.
Phillips plans to apply his award to understand how collective phenomena emerge from strong electron interactions and precisely how the principle of scale invariance simplifies the normal state of copper-oxide superconductors.
