N=(0,2) Deformation of CP(1) Model: Two-dimensional Analog of N=1 Yang-Mills Theory in Four Dimensions

description: We consider two-dimensional $\mathcal{N}=(0,2)$ sigma models with the CP(1) target space. A minimal model of this type has one left-handed fermion. Nonminimal extensions contain, in addition, $N_f$ right-handed fermions. Our task is to derive expressions for the $β$ functions valid to all orders. To this end we use a variety of methods: (i) perturbative analysis; (ii) instanton calculus; (iii) analysis of the supercurrent supermultiplet (the so-called hypercurrent) and its anomalies, and some other arguments. All these arguments, combined, indicate a direct parallel between the heterotic $\mathcal{N}=(0,2)$ CP(1) models and four-dimensional super-Yang-Mills theories. In particular, the minimal $\mathcal{N}=(0,2)$ CP(1) model is similar to ${\mathcal N}=1$ supersymmetric gluodynamics. Its exact $β$ function can be found; it has the structure of the Novikov-Shifman-Vainshtein-Zakharov (NSVZ) $β$ function of supersymmetric gluodynamics. The passage to nonminimal $\mathcal{N}=(0,2)$ sigma models is equivalent to adding matter. In this case an NSVZ-type exact relation between the $β$ function and the anomalous dimensions $γ$ of the "matter" fields is established. We derive an analog of the Konishi anomaly. At large $N_f$ our $β$ function develops an infrared fixed point at small values of the coupling constant (analogous to the Banks-Zaks fixed point). Thus, we reliably predict the existence of a conformal window. At $N_f=1$ the model under consideration reduces to the well-known $\mathcal{N}=(2,2)$ CP(1) model.

description: Several patterns of numbers can be revealed by arranging them in triangular or some particular arrangement. Pascal’s triangle is one example of arrangement of numbers in triangular form where we explore abundant prop�erties of numbers connected with so many branches of mathematics. In this paper, I will introduce one such triangle consisting natural numbers. Using this basic and simple arrangement of numbers, I had proved seven results in this paper. These results will provide great motivation to understand the hidden structure of numbers.
Opportune conflicts : the EU's engagement with de facto states

description: The thesis examines why and how the European Union (EU) engages with de facto states. Due to the state-centric framework’s structural impotence, de facto states cannot be appropriately understood, and hence tension continues. Although the statist order has been passively sustained, de facto states have not automatically disappeared. Worse, when the embodied conflicts cannot be held any longer or are accidentally triggered, accumulative resentment leads to military confrontations. Since the state-centric framework enshrining the exclusivity of nation-states is analytically parochial, the thesis takes a sociological turn by employing the anomie theory to understand the otherwise marginalised and biased de facto states. Developed by Émile Durkheim, the anomie theory focuses on collective consciousness and the ramifications resulting from its absence. Without conventional statehood, both the EU and de facto states are anomalies in the international arena. Nevertheless, whereas the EU, as a post-modern force, has been exceptionalised and accommodated, de facto states, as pre-modern social forces, should be, but have not been, eliminated. Given this, by taking de facto states as anomie resulting from the displaced collective consciousness, the thesis studies the EU engagement with them in and beyond the state-centric framework. To understand the EU’s engagement with de facto states and its engagement without recognition policy, the thesis analyses three case studies: Abkhazia, Somaliland and Taiwan from 1989 to 2019 via document analysis and expert/policy-maker interviews. As will be revealed in the thesis, the engagement policy cannot be fully comprehended by detaching it from the EU’s global ambition and policy innovations. In exercising influence in world politics, the EU follows the normative pathway by making its presence felt. Concerning the opportune dimensions of such engagement, it has not only catalysed the EU’s development of state-like power, but also signposted a possible scenario wherein the debilitating statist order can be transcended, albeit towards a yet-to-be-determined destination.

description: The ν=5/2 anti-Pfaffian state and the ν=2/3 state are believed to have an edge composed of counter-propagating charge and neutral modes. This situation allows the generation of a pure thermal bias between two composite edge states across a quantum point contact (QPC) as was experimentally established in Nature 466, 585 (2010). We show that replacing the QPC by a quantum dot provides a natural way for detecting the neutral modes via the finite current generated by the thermoelectric response of the dot. We also show that the degeneracies of the dot spectrum, dictated by the conformal field theories (CFTs) describing these states, induce asymmetries in the thermoelectric current peaks. This in turn provides a direct fingerprint of the corresponding CFT.

description: We study, within phenomenological Lagrangian approach, the possibility that the near-threshold peak found in the phi-photoproduction cross section is caused by a resonance. We show that, by employing a J^P=3/2^- resonance with a mass of 2.08 +/- 0.05 GeV and a width of 0.570 +/- 0.169 GeV, the LEPS data which include new data on nine spin-density matrix elements can indeed be described reasonably well. We also find that the ratio of helicity amplitudes A_1/2/A_3/2 calculated from the resulting coupling constants differs in sign from that of D13(2080). The resonance is further found to be able to improve the theoretical description of omega photoproduction against a new set of data if a large value for OZI evading parameter is assumed.

VD rates and treatment facilities varied among the warring parties, depending on geography and strategy, as well as economic, national, and social differences. The militaries’ goal in treating VD was the speedy return of as many soldiers as possible to service. The great wartime spread of VD among military personnel and civilians also affected the permeability of the home and fighting fronts.

description: As it is well known, classical special relativity allows the existence of three different kinds of particles: bradyons, luxons and tachyons. Bradyons have non-zero mass and hence always travel slower than light. Luxons are particles with zero mass, like the photon, and they always travel with invariant velocity. Tachyons are hypothetical superluminal particles that always move faster than light. The existence of bradyons and luxons is firmly established, while the tachyons were never reliably observed. In quantum field theory, the appearance of tachyonic degrees of freedom indicates vacuum instability rather than a real existence of the faster-than-light particles. However, recent controversial claims of the OPERA experiment about superluminal neutrinos triggered a renewed interest in superluminal particles. Driven by a striking analogy of the old Frenkel-Kontorova model of a dislocation dynamics to the theory of relativity, we conjecture in this note a remarkable possibility of existence of the fourth type of particles, elvisebrions, which can be superluminal. The characteristic feature of elvisebrions, distinguishing them from tachyons, is that they are outside the realm of special relativity and their energy remains finite (or may even turn to zero) when the elvisebrion velocity approaches the light velocity.

description: It is shown that the probabilities for the spin singlet can be reproduced through classical resources, with no communication between the distant parties, by using merely shared (pseudo-)randomness. If the parties are conscious beings aware of both the hidden-variables and the random mechanism, then one has a conspiracy. If the parties are aware of only the random variables, they may be induced to believe that they are able to send instantaneous information to one another. It is also possible to reproduce the correlations at the price of reducing the detection efficiency. It is further demonstrated that the same probability decomposition could be realized through action-at-a-distance, provided it existed.

On Iceland's financial crisis
Creators: name: Fantauzzo, Shaun
Publisher: name: University of British Columbia
Year: 2013

description: The global financial crisis has provoked a robust debate in international political economy literature. Existing studies afford readers with a thorough analysis of the impacts of neoliberalism and market fundamentalism, both of which are regarded as determinants of economic and political volatility. These studies identify a relationship between financialization and volatility that is encouraging as it permits for a more qualitative assessment of global phenomena, therefore facilitating a greater understanding of country-level experiences of the global financial crisis, of which there exists substantial and puzzling variation. Iceland’s financial crisis is an example of this variation. Though Iceland’s financial liberalization occurred during an era of unprecedented international financialization, this does not explain why Iceland’s government prohibited foreign competition, nor does it explain the rapid, astronomical growth of Iceland’s banking sector between 2002 and 2008. Furthermore, Iceland’s refusal and subsequent inability to honor foreign debt obligations represents a new development that merits addition consideration. These discrepancies provoke a number of questions regarding the impact that Iceland’s institutional structure has on domestic and international developments, such as the liberalization of its financial sector and the financialization of the global economy. This suggests not that Iceland’s financial crisis is a purely domestic phenomenon, but rather that domestic institutions played a unique role in exacerbating the impact of neoliberalism and market fundamentalism. I develop a conceptual framework informed by Mancur Olson’s theory of ‘institutional sclerosis’ to reveal the institutions that pre-dated Iceland’s financial collapse and argue that Iceland’s corporatist structure is conducive to capture, resulting in a disproportionately overextended banking sector. In addition, I summarize the events of Iceland’s debt negotiations to provide a more comprehensive understanding of what influenced Iceland’s politicians to provide continued support for honoring foreign debt obligations despite a clear ‘no’ mandate afforded by Icelanders in both referendums, as well as why Iceland honored foreign debt obligations altogether, allowing for proper conclusions to be drawn about Iceland’s recovery model and its implications for existing theories in the fields of international political economy and global governance.

Entanglement entropy of a quantum unbinding transition and entropy of DNA

description: Two significant consequences of quantum fluctuations are entanglement and criticality. Entangled states may not be critical but a critical state shows signatures of universality in entanglement. A surprising result found here is that the entanglement entropy may become arbitrarily large and negative near the dissociation of a bound pair of quantum particles. Although apparently counter-intuitive, it is shown to be consistent and essential for the phase transition, by mapping to a classical problem of DNA melting. We associate the entanglement entropy to a subextensive part of the entropy of DNA bubbles, which is responsible for melting. The absence of any extensivity requirement in time makes this negative entropy an inevitable consequence of quantum mechanics in continuum. Our results encompass quantum critical points and first-order transitions in general dimensions.

Cold flow improvements to biodiesel through the use of heterogeneous catalytic skeletal isomerization
Creators: name: Reaume, Stephen John
Publisher: name: University of British Columbia
Year: 2013

description: Biodiesel is a promising alternative to petroleum diesel with the potential to reduce overall net CO₂ emissions. However, the high cloud point of biodiesel must be reduced when used in cold climates. Cloud point is the temperature at which solid crystals first start to appear. Skeletal isomerization of biodiesel and/or its feedstocks was investigated to reduce the high cloud point. Catalytic isomerization and hydroisomerization reactions were carried out on pure unsaturated fatty acid (UFA) and saturated fatty acid (SFA) samples, respectively. The catalyst used for the experiments was a beta zeolite and 0.5 wt% Pt-doped beta zeolite for the isomerization and hydroisomerization reactions, respectively. Reaction conditions of temperature, pressure, co-catalyst and time were varied to find an optimal reduction in the cloud point of the products. It was concluded that isomerization was unsuccessful at reducing the cloud point; in contrast, hydroisomerization was successful at reducing cloud point. A 10 degree Celsius reduction was achieved at 285 degrees Celsius and 4.0 MPa H₂ pressure. The next stage of the research studied the combined effects of isomerization and hydroisomerization on a mixture of UFAs and SFAs, namely oleic and palmitic acids. It was shown that the combination of the reaction gave a cloud point reduction of 7.5 degrees Celsius on a 55/45 mass ratio of oleic to palmitic acids. These results led to the conclusion that SFAs and UFAs through skeletal isomerization can reduce the cloud point of a mixture of fatty acids. Thus, vegetable oil feedstocks can be improved for their biodiesel cloud point. A study of ten different oils was conducted with varying contents of fatty acids. Results have shown that high unsaturated fatty acid biodiesels increased in cloud point, due to the hydrogenation side reaction. In contrast, low unsaturated fatty acid biodiesels yielded cloud point reductions, and overall improvement in the flow properties. A maximum cloud point reduction of 16.5 degrees Celsius was observed with coconut oil as the starting material. These results led to the design of an optimal cloud point improvement process of for vegetable oil biodiesel of: hydrolysis (of vegetable oil → hydroisomerization (300 degrees Celsius, 4.0 MPa H₂ pressure → and esterification.

description: We present pulsed electron-nuclear double resonance (ENDOR) experiments which enable us to characterize the coupling between bismuth donor spin qubits in Si and the surrounding spin bath of 29Si impurities which provides the dominant decoherence mechanism (nuclear spin diffusion) at low temperatures (< 16 K). Decoupling from the spin bath is predicted and cluster correlation expansion simulations show near-complete suppression of spin diffusion, at optimal working points. The suppression takes the form of sharply peaked divergences of the spin diffusion coherence time, in contrast with previously identified broader regions of insensitivity to classical fluctuations. ENDOR data suggest that anisotropic contributions are comparatively weak, so the form of the divergences is largely independent of crystal orientation.

The Seiberg-Witten curve was constructed previously for the low-energy effective theory of the non-critical E-string theory in R^4 x T^2. We clarify how the amplitudes are written as polynomials in a finite number of generators expressed in terms of the Seiberg-Witten curve. We determine the coefficients of the polynomials by solving the holomorphic anomaly equation and the gap condition, and construct the amplitudes explicitly up to genus three. The results encompass topological string amplitudes for all local del Pezzo surfaces.

description: We present an algorithm for simulating the equations of ideal magnetohydrodynamics and other systems of differential equations on an unstructured set of points represented by sample particles. Local, third-order, least-squares, polynomial interpolations (Moving Least Squares interpolations) are calculated from the field values of neighboring particles to obtain field values and spatial derivatives at the particle position. Field values and particle positions are advanced in time with a second order predictor-corrector scheme. The particles move with the fluid, so the time step is not limited by the Eulerian Courant-Friedrichs-Lewy condition. Full spatial adaptivity is implemented to ensure the particles fill the computational volume, which gives the algorithm substantial flexibility and power. A target resolution is specified for each point in space, with particles being added and deleted as needed to meet this target. Particle addition and deletion is based on a local void and clump detection algorithm. Dynamic artificial viscosity fields provide stability to the integration. The resulting algorithm provides a robust solution for modeling flows that require Lagrangian or adaptive discretizations to resolve. This paper derives and documents the Phurbas algorithm as implemented in Phurbas version 1.1. A following paper presents the implementation and test problem results.

description: We investigate the collective optomechanics of an ensemble of scatterers inside a Fabry-Perot resonator and identify an optimized configuration where the ensemble is transmissive, in contrast with the usual reflective optomechanics approach. In this configuration, the optomechanical coupling of a specific collective mechanical mode can be several orders of magnitude larger than the single-element case, and long-range interactions can be generated between the different elements since light permeates throughout the array. This new regime should realistically allow for achieving strong single-photon optomechanical coupling with massive resonators, realizing hybrid quantum interfaces, and exploiting collective long-range interactions in arrays of atoms or mechanical oscillators.

description: We show that the electronic structures of the title compounds predicted by density functional theory (DFT) are well described by tight binding models. We determine the frustration ratio, J'/J, of the Heisenberg model on the anisotropic triangular lattice, which describes the spin degrees of freedom in the Mott insulating phase for a range of Pd(dmit)2 salts. All of the antiferromagnetic materials studied have J'/J < 0.5 or J'/J > 0.9, consistent with predictions for the Heisenberg model. All salts with 0.5 < J'/J < 0.9, where many-body theories find a number of competing ground states, are known, experimentally, to be charge ordered, valence bond solids or spin liquids.

description: We consider the random linear precoder at the source node as a secure network coding. We prove that it is strongly secure in the sense of Harada and Yamamoto and universal secure in the sense of Silva and Kschischang, while allowing arbitrary small but nonzero mutual information to the eavesdropper. Our security proof allows statistically dependent and non-uniform multiple secret messages, while all previous constructions of weakly or strongly secure network coding assumed independent and uniform messages, which are difficult to be ensured in practice.

description: The electronic spectrum on the spherical surface of a topological insulator reflects an active property of the helical surface state that stems from a constraint on its spin on a curved surface. The induced effective vector potential (spin connection) can be interpreted as an effective vector potential associated with a fictitious magnetic monopole induced at the center of the sphere. The strength of the induced magnetic monopole is found to be g=2pi, -2pi, being the smallest finite (absolute) value compatible with the Dirac quantization condition. We have established an explicit correspondence between the bulk Hamiltonian and the effective Dirac operator on the curved spherical surface. An explicit construction of the surface spinor wave functions implies a rich spin texture possibly realized on the surface of topological insulator nanoparticles. The electronic spectrum inferred by the obtained effective surface Dirac theory, confirmed also by the bulk tight-binding calculation, suggests a specific photo absorption/emission spectrum of such nanoparticles.

Investigating factor structure and validity evidence of a measure assessing students' perceptions of teachers' social and emotional competence
Creators: name: Whitehead, Jenna Katherine
Publisher: name: University of British Columbia
Year: 2013

description: This study introduces the Students’ Perceptions of Teacher’s Social and Emotional Competence scale (TSEC) for early adolescents and presents psychometric findings regarding its reliability and validity. A sample of 360 students in 5th to 7th grade provided data on the TSEC and measures of empathy, well-being, school adjustment, as well as measures of their teacher’s emotional and personal support. Teachers provided data on students’ social and emotional competence and aggression, as well as quality of closeness and conflict in their relationship with each of their students. Results indicated that the TSEC had a unidimensional factor structure and high internal consistency. Scores on the TSEC differed by gender and grade-level, with girls reporting their teachers higher on the TSEC than boys and 5th grade students reporting their teachers higher on the TSEC than 6th grade students. The TSEC demonstrated evidence of convergent validity, providing support for this measure as a psychometrically sound instrument for use with this age group. This study provides insight into relations of students’ perceptions of teacher SEC to students’ social and academic outcomes, and the student-teacher relationship. Limitations and future directions are discussed with regard to the relevance of the TSEC for research and educational applications.
