Applications of Many Body Dynamics of Solid State Systems to Quantum Metrology and Computation
(2013-03-18)This thesis describes aspects of dynamics of solid state systems which are relevant to quantum metrology and computation. It may be divided into three research directions (parts). For the first part, a new method to enhance ... -
Applying Bayesian Inference to Measurements of Colloidal Dynamics
(2021-05-14)A generative model provides a framework for applying Bayesian methods to complex experimental data like microscope images by describing them as a statistical probability distribution. One of the most valuable features ... -
Carbon Nanotubes for the Generation and Imaging of Interacting 1D States of Matter
(2014-06-06)Low-dimensional systems in condensed matter physics exhibit a rich array of correlated electronic phases. One-dimensional systems stand out in this regard. Electrons cannot avoid each other in 1D, enhancing the effects of ... -
Controlling Atomic, Solid-State and Hybrid Systems for Quantum Information Processing
(2013-10-18)Quantum information science involves the use of precise control over quantum systems to explore new technologies. However, as quantum systems are scaled up they require an ever deeper understanding of many-body physics ... -
Cooperativity, Fluctuations and Inhomogeneities in Soft Matter
(2013-09-30)This thesis presents four investigations into mechanical aspects of soft thin structures, focusing on the effects of stochastic and thermal fluctuations and of material inhomogeneities. First, we study the self-organization ... -
Electrical and thermoelectric transport in mixed-dimensional graphitic mesoscopic systems
(2022-09-12)Confining electrons to fewer than three spatial dimensions increases the relative strength of potential to kinetic energy, which can generate a wide variety of novel emergent quantum phenomena. I will discuss three experiments ... -
Engineering the excitonic and photonic properties of atomically thin semiconductors
(2023-01-04)Atomically thin and layered semiconductors are of broad interest to the physics and engineering communities in the past decade. As true members of the mesoscale, such materials have exotic and potentially advantageous ... -
First-Principles Multiscale Investigation of Structural and Chemical Defects in Metals
(2013-03-08)This thesis explores multiscale approaches to describe structural and chemical defects in metals. Particular emphasis is placed on investigating processes involving grain boundaries (GBs) in combination with impurity and ... -
Frankenstein's Tiniest Monsters: Inverse Design of Bio-inspired Function in Self-Assembling Materials
(2023-05-12)Despite tremendous advances in synthetic materials design, the complexity achievable in artificial systems is dwarfed by the complexity of living matter. One cause of this discrepancy is that biological systems fundamentally ... -
From Hopping to Ballistic Transport in Graphene-Based Electronic Devices
(2013-10-08)This thesis describes electronic transport experiments in graphene from the hopping to the ballistic regime. The first experiment studies dual-gated bilayer graphene devices. By applying an electric field with these dual ... -
Hierarchical phases of filamentary active matter
(2021-11-16)Studies of active matter seek to identify the properties of materials made from dense collections of animate objects. Within this effort, one promising direction aims to reconstruct the remarkable properties of living ... -
High-performance predictions of electron and phonon transport from first principles
(2023-05-17)The electrical and thermal transport properties of materials are central to their use in everyday technology. Using modern computational methods, theoretical predictions of transport can be made accurately for many materials. ... -
Hot Carriers in Graphene
(2014-10-22)When energy relaxation between electrons and the lattice is slow, an elevated electronic temperature different from that of the lattice persists. In this regime, hot charge carriers control the energy transport in a material. ... -
Hydrodynamics and Viscous Flow in Graphene Measured with Johnson Noise Thermometry
(2024-03-12)In this dissertation, we investigate thermal transport phenomena in 2-dimensional monolayer and bilayer graphene, both of which are candidates for strongly interacting, correlated electronic systems. The interactions between ... -
Interacting quantum materials and their acoustic analogs
(2022-01-20)When electrons in solids interact strongly with one another, they often produce unexpected, emergent phases, like high-temperature superconductivity or fractional quantum Hall states. In this thesis, I approach this strongly ... -
