    • A Thermochemical Cryogenic Buffer Gas Beam Source of ThO for Measuring the Electric Dipole Moment of the Electron 

      West, Elizabeth Petrik (2017-05-04)
      The discovery of an electric dipole moment of the electron (eEDM) within a few orders of magnitude of the current best limit would reveal the existence of time-reversal symmetry (T) violating physics beyond the Standard ...
    • A Transdimensional Perspective on Dark Matter 

      Daylan, Tansu (2018-05-13)
      Robust uncertainty propagation and marginalization over nuisance parameters is the key to per- form robust inference. This thesis introduces a transdimensional, hierarchical, threshold-free, and Bayesian inference framework. ...

      Accurate treatment of the long-range electron correlation energy, including dispersion interactions, is essential for describing the structure, dynamics, and function of a wide variety of systems. Among the most accurate ...
    • Advances in the Singlet-Triplet Qubit 

      Orona, Lucas A. (2020-05-12)
      My work on singlet-triplet spin qubits has bridged between the eras of two different semiconductors, gallium arsenide (GaAs) and silicon germanium (SiGe), that have been used in the Yacoby Lab. I have chosen to report my ...
    • Algorithmic approaches to ecological rationality in humans and machines 

      Dasgupta, Ishita (2020-01-08)
      In a complex and ever-changing world, how do humans reason as intelligently as they do—especially given limited energy, data, and time? How can understanding this guide us toward building better artificially intelligent ...
