    Proton Tomography in Momentum Space using an Electron Beam Sucheta Jawalkar Department of Physics, Duke University (Truman alum) Measurements in the late 1980s at CERN revealed that quark spins account for a small fraction of the proton’s spin. This so-called spin crisis spurred a number of new experiments to understand the spin structure of the […]

    Novel Effects of High Pressure on Superconductivity Narelle J. Hillier Department of Physics, Washington University Superconductivity has been studied extensively since it was first discovered by Kamerlingh Onnes over 100 years ago. High pressure studies are vital in furthering our understanding of this novel state, as pressure allows researchers to enhance the properties of existing […]

    Efficiency of a microwave photon detector based on a current-biased Josephson junction Amrit Poudel Department of Physics, University of Wisconsin—Madison Superconducting qubits are promising candidates for quantum information processing. Recently, circuit quantum electrodynamics (cQED) has emerged as a novel paradigm for the study of radiation-matter interaction in mesoscopic systems. Moreover, cQED is an attractive candidate […]

    Physics at high energy density: bringing astrophysics to the lab Carlos Di Stefano Department of Atmospheric, Oceanic, and Space Sciences, University of Michigan (Truman alum) High-energy-density (HED) physics is an emergent field exploring the properties of matter in an exotic regime of extreme temperatures and pressures. These conditions, occurring naturally only in astrophysical processes in […]

    Study of the Electronic Pairing Symmetry in Iron-Based Superconductors Ryan T. Gordon Department of Physics, Western Illinois University The study of the symmetry of the wavefunction (order parameter) for electrons in newly discovered iron-based superconductors is one of crucial importance for understanding how this fascinating state of matter is possible in them. There are two […]

    Young Star Clusters and the Initial Mass Function Bruce Wilking Department of Physics and Astronomy, University of Missouri—St Louis The distributions of stellar masses, or Initial Mass Functions (IMFs), in the disk of our Galaxy and in visible star clusters are remarkably similar. But subtle differences do exist and must trace back to the star […]

    Magnetic field effects in organic semiconductors: from touch screen displays to bird navigation Markus Wohlgenannt Department of Physics and Astronomy, University of Iowa Organic semiconductors are electrically conducting plastic materials, whose main applications are as display pixels as well as plastic solar cells. We show that these materials are however also promising as magnetic field […]
