AbstractThe 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.

Abstract: Last year, student protestors at Bates College posed a powerful question: "What radical decisions is Bates making today to put the College 100 years ahead of our peer schools?" I believe we should be asking this question everywhere, especially at our public universities. In my talk,I respond with possible answers in the context of science, technology, engineering, and mathematics, fields where minoritized students -- and in tandem, faculty -- are especially marginalized in academia.

Abstract: The first few detections of gravitational waves by the LIGO and Virgo observatories have opened an entire new way for us to study the Universe. The brightest gravitational wave signals are powered by collisions of the most compact astrophysical objects known to exist: black holes and neutron stars. In such events, two objects more massive than the sun merge in just a few milliseconds, releasing a tremendous amount of energy.
