UNC-CH Physics and Astronomy Colloquium Eduard Chekmenev, Vanderbilt University "Hyperpolarized NMR Contrast Agents for Molecular Imaging" The significant (usually orders-of-magnitude) increase in nuclear spin polarization above the thermal-equilibrium level is called hyperpolarization. Because the NMR signal is directly proportional to … Read more

UNC-CH Physics and Astronomy Colloquium Alfred Shapere, University of Kentucky "The Many Facets of Time Crystals" Time crystals are systems that exhibit spontaneous breaking of time translation symmetry, analogously to ordinary crystals, which break space translation symmetry. Unlike space crystals, … Read more
