  • Subwavelength light confinement and quantum chaos in micro- and nano-structured metamaterials

    Creator:
    Govyadinov, Alexander A.
    Abstract:
    This dissertation concerns a broad range of unique phenomena related to the light propagation at nano- and micro-scales. To access the nano-domain, we introduce anisotropy-based waveguides with positive- and negative-index modes. These novel structures allow energy propagation in subwavelength regions and, in contrast to surface waves, have the mode structure...

  • Heavy fermion effective mass in the superconducting vortex state

    Creator:
    Townsend, Emily A.
    Abstract:
    The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...
