  • Redundant information in a spin system beyond pure decoherence

    Creator:
    Svesko, Andrew M.
    Abstract:
    Quantum physics in the Copenhagen interpretation places an unsatisfying divide between the quantum and classical worlds. Decoherence -- the destruction of superposition states of the system -- helps us understand how the quantum transitions to the classical. Quantum Darwinism builds on decoherence to understand how information about the system is...

  • Investigation Into the Use of a Lead Slowing Down Spectrometer for Neutron Cross Section Analysis

    Creator:
    Keppen, Jackson D.
    Abstract:
    A lead slowing-down spectrometer (LSDS) was modeled in the hopes of beginning a nuclear data development campaign at Oregon State University. An LSDS can be used for neutron interrogation techniques, such as determining isotopic inventory of a sample of unknown components or determining the cross section of a sample of...

  • 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...

  • The role of competition, community, and priority in the discovery of the tau lepton

    Creator:
    Swanner, Leandra
    Abstract:
    This study examines the interactions between the scientific communities of the Lawrence Berkeley Laboratory (LBL) and the Stanford Linear Accelerator Center (SLAC) in the discovery of the tau lepton by physicist Martin Perl between 1973- 1977. Perl became interested in searching for heavy leptons through positron-electron collision experiments using the...
