COUPLING NITROGEN VACANCY CENTERS IN DIAMOND TO A NANOMECHANICAL OSCILLATOR

Oo, Thein Htay (University of Oregon, 2018-04-10)

Exotic aspects of quantum mechanics, such as quantum entanglement, can be exploited to solve computational problems that are impractical to solve with conventional computers. With the realization of robust solid-state ...
Direct Experimental Observation of 3D Vortex States in Multilayer Fe/Gd using Scanning Electron Microscopy with Polarization Analysis (SEMPA)

Moraski, Rich (University of Oregon, 2023-07-06)

The global market for power solely for data center usage is estimated to be $12.4 billion by 2027[1]. In 2021, data center electricity consumption was ∼400 TW h, representing almost 2% of the global energy demand[2]. Ongoing ...
Electron Interferometry Using an Amplitude Dividing Grating Beamsplitter: Development and Application

Yasin, Fehmi (University of Oregon, 2019-09-18)

Electron microscopes can be used for atomic resolution imaging myriad materials including semiconductor nanomaterials integral to modern technology, biomolecular materials that compose all of life and the carbon energy ...
Electron orbital angular momentum: preparation, application and measurement

Harvey, Tyler (University of Oregon, 2017-09-06)

The electron microscope is an ideal tool to prepare an electron into a specified quantum state, entangle that state with states in a specimen of interest, and measure the electron final state to indirectly gain information ...
Grating-Based Beam Shaping and Inelastic Interferometry with Free Electrons

Johnson, Cameron (University of Oregon, 2021-09-13)

Here I present studies for the manipulation of free electrons using materialholograms and the application of holographically structured electrons in interferometry. The research in this dissertation can be divided into two ...
Interaction-free measurements with electrons

Turner, Amy (University of Oregon, 2022-10-04)

Quantum-enhanced electron imaging promises highly efficient, low-damage transmission electron microscopy, transforming high-resolution imaging of samples affected by beam irradiation. One proposed quantum protocol for ...
Mapping topological magnetization and magnetic skyrmions

Chess, Jordan (University of Oregon, 2018-04-10)

A 2014 study by the US Department of Energy conducted at Lawrence Berkeley National Laboratory estimated that U.S. data centers consumed 70 billion kWh of electricity[1]. This represents about 1.8% of the total U.S. ...
Optical and Mechanical Quantum Control of Nitrogen Vacancy Centers in Diamond

Amezcua, Mayra (University of Oregon, 2018-09-06)

Current proposals for the design of quantum computer architectures include combining different quantum systems with designated tasks to build a device that can efficiently store, process, and transfer quantum information. ...
Resonantly Enhanced Sagnac Interferometry Using Surface Plasmon Polaritons

Hake, Brian (University of Oregon, 2020-02-27)

We present a theoretical model and experimental results for a Sagnac ring interferometer resonantly enhanced via surface plasmon resonance (SPR). One defining characteristic of a resonance is the π change in phase that ...
The Application of Interferometric Electron Microscopy for Nanomagnetic Imaging

Greenberg, Alice (University of Oregon, 2021-04-27)

The study of micromagnetics both yields important applications, like computer hard disks which enabled the creation of the internet, and continues to reveal surprising phenomena and open new scientific questions, like the ...
