Emergent Phenomena in Matrix Models
… matrix models and particularly the property of emergent phenomena in them. We start discussing a 2-matrix model of Yang-Mills type that exhibits an emergent topology in the strong coupling limit. We use Monte-Carlo simulations to obtain various observables that allow us to get more insight in …

Quantum Critical Ferroelectricity and Emergent Phenomena in KTaO3 and SrTiO3
This thesis explores the quantum phase diagrams of KTaO3 and SrTiO3, both quantum paraelectrics near to a ferroelectric quantum critical point, including study of material properties which may be influenced by proximity to a ferroelectric quantum phase transition. A quantum critical phase …

EMERGENT PHENOMENA AND NOVEL DEVICES BASED ON SPIN-ORBIT COUPLING AT COMPLEX OXIDE INTERFACES
… transduction mechanism. This thesis explores the emergent phenomena and quantum phases at heterostructures and interfaces with a broken symmetry aiming at novel and large SOC effects.

A Naturalistic Ontology of Generic Traits and Emergent Phenomena: Reinterpreting the Metaphysics of John Dewey
… generic traits in this way, I link them to an emergent theory of generation. Thus, the generic traits of existence are the common grounds for particular existences, relations among existences, and the generation of new existences and relations. Experience is a broad term, but Dewey provides the …

Shifting Surfaces: Developing a Visual Language with Emergent Patterns and Abstracted Bodies
… a new visual language. Shifting Surfaces employs emergent phenomena and abstraction to evoke the enmeshed relationship between bodies, ecology, and technology.

Optical Binding Phenomena: Observations and Mechanisms
… simple, intuitive explanations for the observed phenomena. Novel trapped states are reported, that do not conform to the symmetry of the underlying trap. A common theme throughout this thesis is the "emergent'' phenomena that occur when multiple particles are trapped together, which cannot easily …

Powderworld: A Platform for Understanding Generalization via Rich Task Distributions
… – the ideal environment would support a range of emergent phenomena, an expressive task space, and fast runtime. To take a step towards addressing this research bottleneck, this work presents Powderworld, a lightweight yet expressive simulation environment running directly on the GPU. Within …

Emergent Quantum Phenomena in Magic-Angle Twisted Graphene Superlattices
… due to their ability to host a wealth of emergent quantum phenomena. Recently, moiré engineering, also known as twistronics, has emerged as a new approach for creating twodimensional correlated materials. In this thesis, I designed and studied novel moiré quantum matter based on twisted …

The Interplay of Magnetism and Topology in Topological Insulators
… and observation of exotic physics and emergent phenomena. Indeed, in recent years focus has transitioned from finding utility in bare TI devices to investigating combination of topological protection with other effects, such as magnetism and superconductivity. In particular, the …

Emergent behaviors in microbial communities
Physics of systems around us are often emergent, shaped by not only the fundamental constituents but their interactions, structures, and symmetries at larger scales. Microbial communities, which play indispensable roles in nature, are complex active systems that naturally pushes us to the …

Characterization of collective phenomena in cuprate superconductors by momentum-resolved electron energy loss spectroscopy
… and charge density wave materials, that exhibit emergent behavior that cannot be understood through current theories of metals and insulators. These materials are classified by the low temperature ordered phases these materials take on, and there may be several ordered phases interacting over the …

Simulation based micro-founded structural market analysis : a case study of the copper industry
… of granular information, capturing potential emergent phenomena. We believe these three aspects, which are least addressed (none of existing work has addressed the first aspect, and few have addressed the second or the third), are important in assessing scarcity risks. Without them, scarcity …

Impacts of vehicle automation on traffic flow stability
… flow and may influence the development of emergent phenomena such as phantom traffic jams, or traffic stability. This dissertation has four main contributions: (i) experimental evidence to validate that human driving behavior alone is sufficient for the development of phantom jams, (ii) …

Collective structure and dynamics of colloids far-from equilibrium
… lead to dynamic effects resulting in unexpected emergent behavior. Going beyond the traditional scheme of relying on equilibrium statistics and free energy minimization to explain the system behavior, this thesis focuses on the rich structure and dynamics of active colloids, with energy …

Chemical Spin Patterning in Metal-Organic Frameworks
Emergent phenomena are ubiquitous and fundamental to life as we know it, serving as vital environmental regulators, such as the production of honey by honeybees. These phenomena occur when individual components of a system interact, generating new collective behaviors. In magnets, interactions …

Independent two-color optogenetic excitation of neural populations
… which would enable the interrogation of emergent phenomena such as circuit dynamics, plasticity, and neuromodulation. Previous implementations have focused on maximizing spectral separation by driving one channelrhodopsin in the violet (405 nm) and the other in the yellow (590 nm), yet it …

Great Conversations: Systems, Complexity, and Epic Encyclopedic Narratives in Contemporary American Fiction 1960-2007
… world-system by emphasizing the presence of the emergent phenomena, recursive symmetry, and noise that are central to complex systems theories. The work Ludwig von Bertalanffy, Immanuel Wallerstein, and Ilya Prigogine, amongst others, posits that complexity spurs the development of increased …

Non-classical methods for the simulation and design of quantum materials.
… their intricate electronic structure and unique emergent phenomena, such as magnetism, topological states, and superconductivity. Classical methods often struggle to accurately model these systems, especially when quantum effects such as strong electron correlations or entanglement are involved. …

Emergent behaviors in complex microbial ecosystems
… and abundant species. Understanding the complex emergent phenomena of diversity, stability, and invasibility in these communities within a unified framework has been a significant challenge. My PhD thesis addresses this knowledge gap by conducting the first direct test of a theory proposing that …
