R. G. Herb Condensed Matter Seminar
Interplay between superconductivity and ferromagnetism at the LaAlO<sub>3</sub>/SrTiO<sub>3</sub> interface
Time: 3:30 pm
Place: 5310 Chamberlin
Speaker: Venkat Chandrasekhar, Northwestern University
Abstract: The interface between the two band insulators LaAlO3 (LAO) and SrTiO3 (STO) has proved to be host to a rich variety of phenomena, including electric field controlled metal-insulator and superconductor-insulator transitions and ferromagnetism. Recently, ferromagnetism and superconductivity, two normally antagonistic phenomena, have been shown to coexist at the interface. We shall discuss the influence of the ferromagnetism on the superconducting properties of the system. In particular, we show how the magnetization dynamics in the ferromagnet can be used as a tool to explore the superconductor to insulator phase transition.

Condensed Matter Theory Group Seminar
Localization of quantum particles and classical waves in disordered media (Part II)
Time: 4:30 pm
Place: 5310 Chamberlin
Speaker: Peter Wölfle, Karlsruhe Institute of Technology, Germany
Abstract: In the second lecture I review a self-consistent theory of localization and discuss its recent application to interpret experiments on the localization of acoustic waves. The phase relaxation rate in electronic systems is also considered, in particular with respect to recent experiments on ferromagnetic disordered metals. Recent experiments on the localization of ultracold atoms in an optical random potential are reviewed.
