Abstract: The control of recently observed spintronic effects in topological-insulator/ferromagnetic-metal (TI/FM) heterostructures is thwarted by the lack of understanding of band structure and spin texture around their interfaces.

Beginning with Parker's 1958 paper predicting a supersonic outflow from the Sun, theoretical investigations and spacecraft measurements have led to considerable progress in our understanding of the solar wind. In this talk, I will review one of the leading models for the solar wind's origin and discuss what this model may tell us about more distant astrophysical outflows. In this model, the solar wind is powered primarily by Alfven waves, which are like waves on a string, where magnetic field lines play the role of the string.

Abstract: Graphene, an atomically thin sheet of carbon atoms, is a two dimensional semi-metal in which the electrons behave as massless Fermions. Because it is extremely thin and has a low carrier density, the local electronic structure of graphene can be strongly modified by impurities found either in the nearby environment, or introduced via intentional doping. This talk will discuss several impurity related phenomena that are observed in graphene and how they can modify the macroscopic properties that are observed in graphene devices.
