  • Kotson, Michael Christopher (Massachusetts Institute of Technology, 2012)
    In this thesis, we present a catalog of binary stars discovered in the publicly available Kepler database, none of which were included in previous such catalogs published by the Kepler science team. A brief review of other ...
  • Ng, Jonathan, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
    Observations in the Earth's magnetotail and kinetic simulations of magnetic reconnection have shown high electron pressure anisotropy in the inflow of electron diffusion regions. This anisotropy has been accurately accounted ...
  • Davis, Emily, S.B. (Emily J.) Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
    It is currently well-known how to lock an optical cavity on resonance using the Pound- Drever-Hall technique. It is also possible to lock a cavity at a single detuned length using an amplitude modulated laser beam. However, ...
  • Harrington, Kathleen M (Massachusetts Institute of Technology, 2012)
    The GEANT4 physics simulation program is known to have errors in how hadronic interactions are implemented. This has the potential to cause errors in the Monte Carlos used to determine the expected neutron backgrounds in ...
  • Porras Pérez Guerrero, Juan Pablo (Massachusetts Institute of Technology, 2012)
    There is much current interest in thermoelectric devices for sustainable energy. This thesis describes a research project on the synthesis and physical characterization of thermoelectric single crystals. 1In₄Se₃-[delta] ...
  • Randeria, Mallika (Massachusetts Institute of Technology, 2012)
    Phosphorus doped silicon is a prime candidate for spin based qubits. We plan to investigate a novel hybrid technique that combines the advantages of spin selective optical excitations with that of electrical readout ...
  • Speranza, Antony John (Massachusetts Institute of Technology, 2012)
    This work considers some implications of viewing gravity as an emergent force. In such a viewpoint, general relativity arises as the thermodynamic limit of some microscopic theory. As such, one would expect the macroscopic ...
  • Chester, David A., III (Massachusetts Institute of Technology, 2012)
    This thesis project was to write a program in C++ that solves electromagnetic scattering problems for arbitrarily shaped scatterers. This was implemented by using a surface integral formulation of Maxwell's equations, which ...
  • Katz, Rena J. (Rena Jenelle) (Massachusetts Institute of Technology, 2012)
    Energy levels of the valence electron of a single trapped ⁸⁸Sr+ ion can be harnessed as an effective qubit for quantum information processing. The qubit transition to a metastable energy state can be stimulated by a laser ...
  • Fisher, Zachary (Zachary Kenneth) (Massachusetts Institute of Technology, 2012)
    In this thesis, I present experimental results demonstrating the characterization of a planar Paul trap. I discuss the theory of ion trapping and analyze the voltages required for shuttling. Next, the characteristics of a ...
  • Payne, Joshua Estes (Massachusetts Institute of Technology, 2012)
    In this thesis, I designed and implemented a particle-in-cell (PIC) code on a graphical processing unit (GPU) using NVIDA's Compute Unified Architecture (CUDA). The massively parallel nature of computing on a GPU nessecitated ...
  • Lau, Claudia (Claudia M.) (Massachusetts Institute of Technology, 2012)
    Topological insulators are a new class of three-dimensional quantum materials whose interior or bulk is an insulator but whose surface is a conductor. Bi₂Se₃ is a prototypical topological insulator that physicists at MIT ...
  • Fei, Lin, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
    We study a new form of dark matter interaction which may significantly affect the thermal relic abundance of dark matter. This new interaction takes the form C+D --> C+[phi], where D is the dark matter species present ...
  • Mazurenko, Anton (Massachusetts Institute of Technology, 2012)
    We present an experiment exploring electromagnetically induced transparency (EIT) in Rydberg atoms in order to observe optical nonlinearities at the single photon level. ⁸⁷Rb atoms are trapped and cooled using a magneto-optical ...
  • Sun, Fei, S.B. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
    In this thesis, we wish to test the hypothesis that scattering by a random potential causes localization of wave functions, and that this localization is governed by the Born postulate of quantum mechanics. We begin with ...
  • Shen, Nancy (Massachusetts Institute of Technology, 2012)
    Most of the young stars in the Orion Trapezium Cluster are much more peculiar in X-rays than expected, considering their structure, environment, and age. Highly resolved X-ray spectra provide many more details in order to ...
  • Roxlo, Thomas (Thomas Q.) (Massachusetts Institute of Technology, 2012)
    We examine the effects of zero sound wave excitations of charged fermion species living around the charged black hole of an AdS/CFT spacetime. In particular, we show that these bulk modes cause corresponding singularities ...
  • Rankin, Dylan Sheldon (Massachusetts Institute of Technology, 2012)
    We perform an exclusive search for the Higgs boson to gamma-gamma decay via vector boson fusion. We utilize the characteristic features of vector boson fusion, such as the di-jet [Delta][eta] and mass, as well as the ...
  • Greenwood, Ross Norman (Massachusetts Institute of Technology, 2012)
    In this thesis, I investigated the extent to which the inclusion of multiple scalar fields in models of Higgs inflation produces observable departures from the single field case. I designed simulations to numerically solve ...
  • Ramasesh, Vinay (Vinay V.) (Massachusetts Institute of Technology, 2012)
    This thesis reports the achievement of a two-species apparatus for use in an upcoming experiment with fermionic ultracold atomic gases. First, we describe the construction of a laser system capable of cooling and trapping ...
