Show morePhoto-induced phase transitions (PIPT) in quantum systems are the epitome of challenging non-equilibrium many-body phenomena, that also have a wide range of potential applications. Recently interest in light-matter coupled states with an energy gap have yielded evidence for Floquet topological states. In this study we demonstrate nonequilibrium Floquet band formation under ultrafast optical excitation using a one-dimensional topological insulator. As an example, the effects are illustrated using a new Zig-Zag Su-Schrieffer-Heeger model of polyacetylene, which is a paradigmatic Hamiltonian exhibiting nontrivial edge states. Our results indicate short optical pulses feasible in experiments can induce novel topological states, local spectral selection and novel pseudospin textures in polyacetylene. Pump-probe photoemission spectroscopy is able to study these states by measuring Floquet band formation and sizeable energy gaps on femtosecond time scales. We find that optically activated nontrivial variations of sublattice mixing could lead to novel topological phenomenon.The rich variety of states induced by lasers have a wide range of potential applications so that control of these states has become a key objective. We present a computational approach to finding optimal ultrafast laser pulse shapes to induce target states and population inversion in pump-probe PIPT experiments. The Krotov approach for Quantum optimal control theory (QOCT) is combined with a Keldysh Green’s function calculation to describe experimental outcomes such as photoemission, transient single particle density of states and optical responses. Results for a simple model charge density wave (CDW) system are presented, including generation of almost complete population inversion and negative temperature states.

Show more"While the first particle accelerators were electrostatic machines, and several electrostatic storage rings were subsequently commissioned and operated, electrostatic storage rings pose a number of challenges. Unlike motion in the magnetic field, where particle energy remains constant, particle energy generally changes in electrostatic elements. Conservation of energy in an electrostatic element is, in practice, only approximate, and it requires careful and accurate design, manufacturing, installation, and operational use. Electrostatic deflectors require relatively high electrostatic fields, tend to introduce nonlinear aberrations of all orders, and are more challenging to manufacture than homogeneous magnetic dipoles. Accordingly, magnetic storage rings are overwhelmingly prevalent. The search for electric dipole moments (EDMs) of fundamental particles is of key importance in the study of C and CP violations and their sources. C and CP violations are part of the Sakharov conditions that explain the matter-antimatter asymmetry in the universe. Determining the source of CP violations would provide valuable empirical insight for beyond-Standard-Model physics. EDMs of fundamental particles have not to this date been experimentally observed. The search for fundamental particle EDMs has narrowed the target search region; however, an EDM signal is yet to be discovered. In 2008, Brookhaven National Laboratory (BNL) had proposed the frozen spin (FS) concept for the search of a deuteron EDM. The FS concept envisions launching deuterons through a storage ring with combined electrostatic and magnetic fields. The electrostatic and magnetic fields are in a proportion that would, without an EDM, freeze the deuteron's spin along its momentum as the deuteron moves around the lattice. The radial electrostatic field would result in a torque on the spin vector, proportional to a deuteron EDM, rotating the spin vector out of the midplane. The principle of an anomalous magnetic dipole moment (MDM) measurement using a storage ring, shared by BNL's completed E821 Experiment and the ongoing E989 Experiment operated by Fermi National Accelerator Laboratory (FNAL), requires injecting muons into a magnetic ring at the so-called magic momentum. The magic momentum, as defined in this context, would freeze the muon's spin vector along its momentum if the anomalous MDM was zero. The spin precession in the horizontal plane relative to the momentum is proportional to the anomalous MDM. Storage rings for measurement of EDM and anomalous MDM present a new frontier in tracking code accuracy requirements. For accurate tracking of storage rings with electrostatic particle optical elements, it is necessary to model the fringe fields of such elements accurately, in particular, because not doing so provides a mechanism for energy conservation violation. However, the previous research on fringe fields tended to focus on magnetic rather than electrostatic particle optical elements. We will study and model the fringe fields of several electrostatic deflectors. Field falloffs of electrostatic deflectors are slower than exponential, and Enge functions are not suitable for accurate modeling of these falloffs. We will propose an alternative function to model field falloffs of electrostatic deflectors. We will use conformal mapping methods to obtain the main field of the Muon g-2 storage ring high voltage quadrupole, and we will calculate its fringe field and effective field boundary (EFB) using Fourier analysis. Furthermore, we will study tracking of storage rings with electrostatic elements using map methods. We will find that, for simultaneous symplecticity and energy conservation, it is only necessary to enforce symplecticity in COSY INFINITY. We will model and track several benchmark lattices - an electrostatic spherical deflector, a homogeneous magnetic dipole, and a proton EDM lattice - in COSY INFINITY and MSURK89, our in-house eighth order Runge-Kutta-Verner tracking code. Finally, we will investigate spin decoherence and systematic errors in FS and quasifrozen spin (QFS) lattices. Spin decoherence effects are similar in FS and QFS lattices, and spin decoherence in said lattices often remains in the same range over time, indicating the feasibility of EDM measurement using FS and QFS lattices."--Pages ii-iii.

Show moreThe Limits of Sympathy intervenes in the scholarly conversation surrounding the relationship between philanthropic reform and the novel as well as the role of women in philanthropic work during late Victorian England. Importantly, this project brings archival texts, such as the philanthropic case reports of the Charity Organisation Society, into the conversation in order to demonstrate how the professionalization of philanthropy eliminated the role of sympathy in philanthropic work and narrative. Where philanthropic texts created new narrative forms to grapple with the New Poor Laws and the changing urban environment of late Victorian London, novels by George Eliot, Walter Besant, H. G. Wells, Edith Johnstone, and Isabella Ford considered how the adoption of professionalized, distanced discourse affected women's perception of and participation in philanthropic work. These novels demonstrate how our current critical reliance on sympathy as a way to mediate the relationship between philanthropic and poor characters, as well as between reader and novel, no longer works within the context of professionalized philanthropy. -- Abstract.

Show moreThis dissertation describes the ways in which the securitized secular laws of the state act to regulate and control Muslims and the practices of Islam through "terrorism" prosecutions in the United States. In order to eliminate terrorism violence, the security state has created an exception to regular legal norms by establishing a court within a court and a prison within a prison, where normal legal procedures are not followed for those Muslim immigrants and American Muslim citizens accused of "terrorism" related offenses. I address the ways in which Muslims have been conditioned and affected by the securitized secular laws that are applied in "terrorism" cases, and I also discuss how human-rights advocacy around the accused challenge and resist these discriminatory practices. Based on 24 months of ethnographic fieldwork; observations of federal terrorism trials; a review of prison writings; and interviews with families of the accused, activists, lawyers, and human-rights advocates, I address the legal practices of securitized laws concerned with preventing "terrorism," their impact both inside and outside of judicial institutions, and the power of these practices on the lived experiences of Muslim Americans. While some authorities claim that preventive "terrorism" prosecutions are necessary to eradicate violence, I suggest that the main concerns of the security state are really about eradicating religious thought and practices that contradict the secular definition of acceptable religion. -- Abstract.

Show moreWith a purpose of improving the experiences of vernacular musicians who want to become music educators so that more vernacular music-making can occur in K-12 music settings, this study explored the lived musical experiences of two vernacular musicians who successfully became music educators. The two grand tour problems of this study were:1. To describe how two vernacular musicians navigated their undergraduate music education programs.2. To describe if/how their vernacular musicianship contributed to their practice as music teachers. Ethnographic techniques were used within the framework of a multiple narrative case study to present the viewpoints of two participants, Carrie and Harrison (pseudonyms). Both were vernacular musicians prior to pursuing degrees in music education. The two participants’ stories revealed that they felt like they were living in two musical worlds. In their undergraduate experiences, participants felt their Western classical abilities were more highly valued than their vernacular musicianship skills, and they did not feel fully supported by faculty musically. In their teaching lives, their vernacular music-making backgrounds manifested through aural learning and rote teaching, creating, and their classroom environment. Participants experienced feelings of being an impostor during their undergraduate experiences, which, particularly for one participant, created fear and anxiety. These feelings of being an impostor continued into their teaching lives, typically brought about by preconceived program expectations (e.g., performance schedules, high-level student musical performance abilities) from community members and colleagues. These outside influences, at times, determined what vernacular music-making experiences they implemented into their classrooms and when it was “safe” to do so.Based on these data, I suggest institutions of higher education more equally value musics found outside Western classical cultures. This includes an evaluation of their audition processes, the support provided to “non-traditional” students, as well as a re-envisioning of required coursework, field experiences, and performance ensembles. Additionally, I suggest ways that teachers of K–12 musics can create a more diverse music education experience for students by including more vernacular music making. These suggestions include opportunities for informal learning, creative music making, and considerations for the classroom environment.

This study explored the relationship of areas of criminogenic need, risk of recidivism, and official recidivism between gang and non-gang justice-involved youth using the Youth Level of Service/Case Management Inventory (YLS/CMI). Results from regression analyses suggest gang status is positively associated with scores of criminogenic needs, risk of recidivism, and official recidivism. However, gang status was not found to moderate the predictive validity of the YLS/CMI for official recidivism. These results indicated it is important for justice system practitioners to consider gang status when making programming and intervention decisions. Limitations and future directions are also discussed."--Page ii.

In order to transition UHPC materials into mainstream construction practices, there are needs to develop refined mix design procedures that enable production of UHPC using primarily locally available materials, resolves the problems with production of homogeneous UHPC mixtures using commonly available concrete mixers, develop convenient fresh mix workability test methods that consider the peculiar rheology of fresh UHPC mixtures, and quantify some aspects of the UHPC material properties that have not been fully characterized. The UHPC materials were tested for fresh mix flow and hardened concrete compressive strength. The trends in the effects of packing density, water film thickness and excess paste film thickness on compressive strength and fresh mix flow were investigated. The results were used to identify viable ranges of these defining characteristics of UHPC mixtures. Response surface analysis of the fresh mix flow and the hardened concrete compressive strength test results led to identification of the optimum values of mix design parameters. The optimum mix was prepared, and was found to produce a highly desired balance of fresh mix flow and hardened concrete compressive strength, which occurred within the ranges predicted by response surface analysis of experimental results."--Page ii.

XoxF may oxidize both methanol and formaldehyde in some organisms while ExaF demonstrated efficient activity with formaldehyde in the presence of La3+ providing a potential alternative to the H4MPT pathway. RNAseq data provided by Dr. Nathan Good found downregulation of mxa genes and the first gene of the H4MPT pathway, fae, and upregulation of xoxF, xoxF2, and exaF in the presence of La3+ suggesting changes to carbon distribution. I found a sharp decrease in accumulation formaldehyde and fourfold increase in accumulation of formate in the presence of La3+ and hypothesized this was due to the activity of Ln3+ enzymes. I measured the minimum inhibitory concentration (MIC) to methanol metabolism and found decreased sensitivity of a 2206fae mutant from 10 mM to more than 125 mM in the presence of La3+. RNAseq suggested changes to the production of CO2 which I corroborated finding an increased CO2 production of 1.8-fold in the presence of La3+. Together, these data provide the first profile of Ln3+ -dependent methylotrophic metabolism and provides new avenues for research."--Page ii.

Show more"Cylinder-kit dynamics design in an internal combustion engine is highly relevant for the engine performance characteristics, durability and reliability. Since the middle of the 20th century, researchers have been using numerical models to describe the processes that occur in a ring pack. Because it is difficult and extremely costly to conduct experiments on every series of engines to check for the blow-by and oil consumption, a computational analysis can be performed on the ring pack to study the blow-by and oil-consumption characteristics. In this dissertation a 3D CFD simulation model is introduced to analyze the flow between the cylinder liner and the piston. This model allows for calculation of the piston assembly with consideration of the ring dynamics, transient boundary conditions for combustion chamber pressure and temperature as well as thermal distortion of the piston and liner. The determination of the complex geometry of the cylinder-kit is established in a STL (STereoLithography) format by considering the complicated geometrical details of the ring pack such as thermal distortion of piston and liner, ring twist and ring/groove conformability. The blow by and blow back is numerically calculated for a small bore cylinder operating at 2000 RPM and verified by the results of commercially available 1D models. The calculated velocity filed shows substantial circumferential flow in the piston ring pack that is dominated by the ring and groove geometry as well as the relative position of the rings end gap. It is found that the amount of gas that flows back to the combustion chamber increases when the in-cylinder pressure trace decreases from its peak value. The knowledge from this study can be used as a basis for further multiphase calculations containing oil flow such as oil consumption, oil evaporation and eventually cylinder-kit wear."--Page ii.
