G. Her b Condensed Matter Seminar\, John Freeland \, Argonne National Lab DESCRIPTION:Functional oxides based on the transition metal series dis play a wide spectrum of remarkable electronic properties including mag netism\, superconductivity and metal-insulator transitions\, which off er potential important properties for practical applications including colossal responses to external fields\, switchable conductivity\, and efficient energy conversion. However\, under these conditions for app lication\, these systems tend to be driven far away from the equilibri um ground-state. In order to harness these materials for the future\, one of the grand challenges is to understand how to map the non-equilb rium phase space both to seek conditions where new states emerge but a lso as a basis for the design of materials that will help meet the ene rgy needs of the future. In this talk\, I will touch on recent work ra nging from optical excitation[1\,2] to catalysis[3\,4] to watching how materials grow[5] as an introduction to how some of the forefront X-r ay tools are helping us to scratch the surface of this problem.
