  • Noether-type theorems for the generalized variational principle of Herglotz

    Creator:
    Georgieva, Bogdana A.
    Abstract:
    The generalized variational principle of Herglotz defines the functional whose extrema are sought by a differential equation rather than an integral. It reduces to the classical variational principle under classical conditions. The Noether theorems are not applicable to functionals defined by differential equations. For a system of differential equations derivable...

  • Electromagnetic properties of anisotropic plasmonic metamaterials

    Creator:
    Elser, Justin Lee
    Abstract:
    In this dissertation we study the electromagnetic properties of plasmonic metamaterials. We develop an analytical description to solve the fundamental problem of free-space scattering in planar plasmonic systems by utilizing anisotropic metamaterials. We show with exact numerical simulations that these manufactured materials do completely eliminate the scattering, and even in...

  • 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...
