description: Abstract: People have kept companion animals for millennia, a tradition that implies mutual benefits due to its persistence; however, scientific investigations present mixed results. Some research suggests pet owners are less lonely than non-owners, but other findings suggest pet owners have higher psychological distress. Research comparing owners with non-owners is limited, and methodological inconsistencies need to be addressed. This study investigated social support and wellbeing (positive functioning)in cat and dog owners, informed by social support theory,attachment, and social exchange theories. It was hypothesized that (1) pet support would predict well being in addition to human support and (2) at least one aspect of pet–owner relationship quality would influence the relationship between social support and wellbeing. An adult sample of 89 cat owners and 149 dog owners (n= 238; 205 females and 33 males)completed an online survey comprising a demographics questionnaire, the Multidimensional Scale of Perceived Social Support, the Cat/Dog–Owner Relationship Quality Scale, the Psychological Wellbeing Scale, and Satisfaction with Life Scale.Social support measures included some demographics on theoretical grounds to measure the construct multidimensionally. Hierarchical and multiple regressions were conducted, and results indicated that both hypotheses were supported: having more pets significantly predicted greater psychological wellbeing in addition to human social support. Unexpectedly, perceived pet support significantly, positively predicted life satisfaction when perceived emotional closeness with pet was low. These findings indicate that pets may improve psychological functioning and that emotional closeness is an important moderating factor.Practical implications include the social benefits of pets for those who could benefit from greater psychological functioning and improved life satisfaction.

description: Active systems, or active matter, are self-driven systems which live, or function, far from equilibrium - a paradigmatic example which we focus on here is provided by a suspension of self-motile particles. Active systems are far from equilibrium because their microscopic constituents constantly consume energy from the environment in order to do work, for instance to propel themselves. The nonequilibrium nature of active matter leads to a variety of non-trivial intriguing phenomena. An important one which has recently been the subject of intense interest among biological and soft matter physicists is that of the so-called "motility-induced phase separation", whereby self-propelled particles accumulate into clusters in the absence of any explicit attractive interactions between them. Here we review the physics of motility-induced phase separation, and discuss this phenomenon within the framework of the classic physics of phase separation and coarsening. We also discuss theories for bacterial colonies where coarsening may be arrested. Most of this work will focus on the case of run-and-tumble and active Brownian particles in the absence of solvent-mediated hydrodynamic interactions - we will briefly discuss at the end their role, which is not currently fully understood in this context.

description: We use a coarse-graining approach to extract local thermodynamic properties from simulations with a microscopic transport model by averaging over a large ensemble of events. Setting up a grid of small space-time cells and going into each cell's rest frame allows to determine baryon and energy density. With help of an equation of state we get the corresponding temperature $T$ and baryon-chemical potential $μ_{\mathrm{B}}$. These results are used for the calculation of the thermal dilepton yield. We apply and compare two different spectral functions for the $ρ$ meson, firstly a calculation from hadronic many-body theory and secondly a calculation from experimental scattering amplitudes. The results obtained with our approach are compared to measurements of the NA60 Collaboration. A relatively good description of the data is achieved with both spectral functions. However, the hadronic many-body calculation is found to be closer to the experimental data with regard to the in-medium broadening of the spectral shape.

description: The epitaxial growth of (FeCo)x Ge1-x films on Ge and GaAs (001) substrates has been studied systematically with x in the range between 0 and 17 at. %, using combinatorial molecular beam epitaxy (MBE) techniques. Complementary doping using the two transition metal dopants into Ge (001) during MBE growth is shown to produce high quality coherent epitaxial films for transition metal concentrations as high as 11 at. %. As the doping level increases, rough growth occurs, which is accompanied by an increasing amount of stacking faults along the 〈111〉 directions. The crystal lattice that resulted from the rough growth exhibits a large out-of-plane tetragonal distortion. There are no detectable secondary phases up to a combined transition metal concentration of 17 at. %. The behaviors are shown to be invariant with respect to the choice of substrates.

description: Any convex polytope whose combinatorial automorphism group has two orbits on the flags is isomorphic to one whose group of Euclidean symmetries has two orbits on the flags (equivalently, to one whose automorphism group and symmetry group coincide.) Hence, a combinatorially two-orbit convex polytope is isomorphic to one of a known finite list, all of which are 3-dimensional: the cuboctahedron, icosidodecahedron, rhombic dodecahedron, or rhombic triacontahedron. The same is true of combinatorially two-orbit normal face-to-face tilings by convex polytopes.

description: The nonequilibrium dynamics following a quench of strongly repulsive bosonic ensembles in one-dimensional finite lattices is investigated by employing interaction quenches and/or a ramp of the lattice potential. Both sudden and time-dependent quenches are analyzed in detail. For the case of interaction quenches we address the transition from the strong repulsive to the weakly-interacting regime, suppressing in this manner the heating of the system. The excitation modes such as the cradle process and the local breathing mode are examined via local density observables. In particular, the cradle mode is inherently related to the initial delocalization and, following a negative interaction quench, can be excited only for incommensurate setups with filling larger than unity. Alternatively, a negative quench of the lattice depth which favors the spatial delocalization is used to access the cradle mode for setups with filling smaller than unity. Our results shed light on possible schemes to control the cradle and the breathing modes. Finally, employing the notion of fidelity we study the dynamical response of the system after a diabatic or adiabatic parameter modulation for short and long evolution times. The evolution of the system is obtained numerically using the ab-initio multi-layer multi-configuration time-dependent Hartree method for bosons which permits to follow non-equilibrium dynamics including the corresponding investigation of higher-band effects.

description: We present measurements of tunneling magneto-resistance (TMR) in single-wall carbon nanotubes attached to ferromagnetic contacts in the Coulomb blockade regime. Strong variations of the TMR with gate voltage over a range of four conductance resonances, including a peculiar double-dip signature, are observed. The data is compared to calculations in the "dressed second order" (DSO) framework. In this non-perturbative theory, conductance peak positions and linewidths are affected by charge fluctuations incorporating the properties of the carbon nanotube quantum dot and the ferromagnetic leads. The theory is able to qualitatively reproduce the experimental data.

description: Medical adhesives such as quick-cure skin glues and bone cements provide rapid, custom tissue fixation and excellent distribution of mechanical stress around injured tissue, often in conjunction with other fixation methods like stitches and metallic orthopedic implants. The role that medical adhesives play in healing is primarily a passive one, preventing further damage and enabling the body to respond to injury naturally – but these materials have much greater potential. Because of their placement directly at the site of injury, medical adhesives are in a prime position to provide the body with cues that can actively guide and improve tissue regeneration. However, the features that make medical adhesives strong and convenient also make these materials challenging platforms for such biological activity. Additives that aim to install bioactivity into medical adhesives can easily interfere with the factors that make these adhesives mechanically strong, such as: bulk homogeneity, sufficient in situ chemical transformation to achieve cure, polymer chain entanglements, and limited swelling in biological environments. If the tradeoff between bioactivity and mechanical strength could be addressed, the capabilities of bioactive adhesives could be dramatically expanded.The following body of work explores several strategies for incorporating bioactivity into medical adhesives without sacrificing bulk mechanical strength. In particular, novel therapeutic methacrylic (TMA) monomers are reported that provide a platform for controlled, local release of small molecule drugs from a range of medical adhesive matrices. Covalent conjugation of the drug payload to a methacrylic backbone by a hydrolysable tether bond provides not only a new mechanism of controlling the profile of drug release (via the reactivity of the tether bond), but also: greater miscibility of the drug in the adhesive matrix, resulting in decreased phase separation; increased drug delivery efficiency relative to adhesives in which the same drug is incorporated by simple admixing; and significantly improved mechanical strength that is retained even after drug delivery. TMA monomers have been explored as additives capable of delivering pain management drugs from both skin adhesives (Chapter 2) and bone cement (Chapter 3). In addition to the strategy of hydrolysis-controlled drug release, functional graphenic materials (FGMs) that carry and release osteogenic ions have been explored as bioactive additives to bone cements (Chapter 4). In this strategy, the FGMs provide bioactivity, while alterations to the formulation of the bone cement matrix, informed by the chemical structure of the FGMs, are used to mitigate changes to the mechanical integrity of the cement.

description: We report on a study of the epitaxial phase diagram of Co- and Mn-doped Ge(001) magnetic semiconductors. Complementary doping using dopants from different groups of elements can compensate for the effects of lattice strain caused by the doping species. Reducing lattice mismatch with the Ge host has been shown to be the key to stabilizing epitaxial growth and suppressing phase separation at higher doping levels. Applying this approach to other multidopant systems opens new prospects for tailoring highly doped electronic materials.

description: Epitaxial growth and structural properties of Cox Mny Siz thin films on Ge (111) substrates, including the Heusler alloy Co2 MnSi (111), have been studied using combinatorial molecular beam epitaxy (MBE) techniques. In situ reflection high energy electron diffraction and ex situ x-ray diffraction experiments show that high quality coherent MBE growth with fcc (111) stacking can be achieved over a relatively large composition space that includes Co2 MnSi. The highest structural and chemical ordering is observed near the composition of Co0.63 Mn 0.14 Si0.23 rather than that at the Heusler stoichiometry of Co2 MnSi. The in-plane crystallographic axis of the fcc film exhibits a 60°rotation with respect to that of the Ge substrate. The rotation appears to be originated at the film-substrate interface, as a result of the symmetry and stacking of the Ge (111) surface reconstruction.

description: The double-differential cross sections of promptly produced J/psi and psi(2S) mesons are measured in pp collisions at sqrt(s) = 7 TeV, as a function of transverse momentum pt and absolute rapidity abs(y). The analysis uses J/psi and psi(2S) dimuon samples collected by CMS, corresponding to integrated luminosities of 4.55 and 4.90 inverse femtobarns, respectively. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and extend to pt = 120 and 100 GeV for the J/psi and psi(2S), respectively, when integrated over the interval abs(y) < 1.2. The ratio of the psi(2S) to J/psi cross sections is also reported for abs(y) < 1.2, over the range 10 < pt < 100 GeV. These are the highest pt values for which the cross sections and ratio have been measured.

description: This paper discusses axially symmetric contact problems of rigid punch and poroelastic foundation interaction employing Cowin-Nunziato linear poroelasticity model. It is assumed that the punch base has a flat or parabolic shape, and the contact friction is neglected. Using Hankel's integral transform the considered contact problem is reduced to a solution of a singular integral equation with unknown contact stress. To solve this integral equation, the collocation technique is used. In the case of parabolic punch, the contact pressure and the contact area were calculated. Then it is investigated the relation between the force applied to the punch and its displacement, which is one of the main characteristics in material properties determination by means of instrumented indentation method. A comparative analysis of considered quantities for various porosity values was carried out.

description: We investigate the behaviour of single-channel theoretical models of cold and ultracold collisions that take account of inelastic and reactive processes using a single parameter to represent short-range loss. We present plots of the resulting energy-dependence of elastic and inelastic or reactive cross sections over the full parameter space of loss parameters and short-range phase shifts. We then test the single-channel model by comparing it with the results of coupled-channel calculations of rotationally inelastic collisions between LiH molecules and Li atoms. We find that the range of cross sections predicted by the single-channel model becomes increasingly accurate as the initial LiH rotational quantum number increases, with a corresponding increase in the number of open loss channels. The results suggest that coupled-channel calculations at very low energy (in the s-wave regime) could in some cases be used to estimate a loss parameter and then to predict the range of possible loss rates at higher energy, without the need for explicit coupled-channel calculations for higher partial waves.

description: Epitaxial films of CoxMnyGez grown on Ge (111) substrates by molecular-beam-epitaxy techniques have been investigated as a continuous function of composition using combinatorial synchrotron x-ray diffraction (XRD) and x-ray fluorescence (XRF) spectroscopy techniques. A high-resolution ternary epitaxial phase diagram is obtained, revealing a small number of structural phases stabilized over large compositional regions. Ordering of the constituent elements in the compositional region near the full Heusler alloy Co2MnGe has been examined in detail using both traditional XRD and a new multiple-edge anomalous diffraction (MEAD) technique. Multiple-edge anomalous diffraction involves analyzing the energy dependence of multiple reflections across each constituent absorption edge in order to detect and quantify the elemental distribution of occupation in specific lattice sites. Results of this paper show that structural and chemical ordering are very sensitive to the Co: Mn atomic ratio, such that the ordering is the highest at an atomic ratio of 2 but significantly reduced even a few percent off this ratio. The in-plane lattice is nearly coherent with that of the Ge substrate, while the approximately 2% lattice mismatch is accommodated by the out-of-plane tetragonal strain. The quantitative MEAD analysis further reveals no detectable amount (<0.5%) of Co-Mn site swapping, but instead high levels (26%) of Mn-Ge site swapping. Increasing Ge concentration above the Heusler stoichiometry (Co0.5Mn0.25Ge0.25) is shown to correlate with increased lattice vacancies, antisites, and stacking faults, but reduced lattice relaxation. The highest degree of chemical ordering is observed off the Heusler stoichiometry with a Ge enrichment of 5 at.%.

description: The growth mechanism and polymer density in conjugated polymer brush (CPB) films composed of poly(3-methylthiophene) (P3MT) are characterized. X-ray photoelectron spectroscopy experiments show that the initiation of aryl halide monolayers by Pd(PtBu3)2 produces disproportionated monolayer initiators. Unlike disproportionated species formed during the solution-phase initiation of aryl halides, which cannot mediate polymerization, the surface-bound initiators catalyze polymerization to form CPB films with a high grafting density (1.2 nm-2). Rutherford backscattering spectrometry (RBS) experiments show that P3MT CPB films have a characteristic monomer volume density (3.7 nm-3) that is indistinguishable from the volume density of spuncast poly(3-hexylthiophene) films. Using these RBS and XPS results, characteristics of P3MT CPB growth are obtained, including the turnover frequency (7.5 h-1) and polymer molecular weight (300 g/mol·nm).

description: Following Ruffini and Bonazzola, we use a quantized boson field to describe condensates of axions forming compact objects. Without substantial modifications, the method can only be applied to axions with decay constant, $f_a$, satisfying $δ=(f_a\,/\,M_P)^2\ll 1$, where $M_P$ is the Planck mass. Similarly, the applicability of the Ruffini-Bonazzola method to axion stars also requires that the relative binding energy of axions satisfies $Δ=\sqrt{1-(E_a\,/\,m_a)^2}\ll1$, where $E_a$ and $m_a$ are the energy and mass of the axion. The simultaneous expansion of the equations of motion in $δ$ and $Δ$ leads to a simplified set of equations, depending only on the parameter, $λ=\sqrtδ\,/\,Δ$ in leading order of the expansions. Keeping leading order in $Δ$ is equivalent to the infrared limit, in which only relevant and marginal terms contribute to the equations of motion. The number of axions in the star is uniquely determined by $λ$. Numerical solutions are found in a wide range of $λ$. At small $λ$ the mass and radius of the axion star rise linearly with $λ$. While at larger $λ$ the radius of the star continues to rise, the mass of the star, $M$, attains a maximum at $λ_{\rm max}\simeq 0.58$. All stars are unstable for $λ>λ_{\rm max}$ . We discuss the relationship of our results to current observational constraints on dark matter and the phenomenology of Fast Radio Bursts.

The structural and chemical ordering of the alloy has been found to be extremely stable over a large composition range, while elemental site swapping and sublattice vacancies have been identified. A model of anomalous diffraction around the Co and Ge edges is presented and shown to make possible the identification and quantification of these disorders in an epitaxial film.

description: We study scaling and renormalization in two dimensional quantum gravity in a covariant framework. After reviewing the definition of a proper path integral measure, we use scaling arguments to rederive the KPZ relations, the fractal dimension of the theory and the scaling of the reparametrization-invariant two point function. Then we compute the scaling exponents entering in this relations by means of the functional RG. We show that a key ingredient to obtain the correct results already known from Liouville theory is the use of the exponential parametrization for metric fluctuations. We also show that with this parametrization we can recover the correct finite part of the effective action as the $ε\to 0$ continuation of gravity in $d=2+ε$ dimensions.

description: The prospect of integrating electron charge and spin degrees of freedom has invigorated the field of spinpolarized electronics,‘‘spintronics’’ [1,2]. Most activities are focused on Mn-doped compounds of group III-V and II-VI families, where high quality ferromagnetic epitaxial films have been grown with Curie temperature TC reaching 110 K [3]. However, there is considerable interest in higher TC materials particularly in group IVelements, owing to their potential compatibility with current Sibased processing technology. Recent studies [4,5] show that Ge crystals doped with a transition metal element do exhibit ferromagnetism at low temperature but phase separation of dopant-rich compounds remains to be the main obstacle for achieving higher doping concentrations and producing higher TC materials. Therefore, the bottleneck for implementing spintronics continues to be the lack of materials candidates. Here we report the synthesis and properties of high quality epitaxial films of high TC magnetic semiconductors of Co and Mn-doped Ge. We show that doping with two elements can stabilize structures at higher doping concentrations than those doped with one of the elements, and that the strong interplay between structure and magnetism gives rise to novel magnetotransport phenomena
The Rhetorical Force of the Law: An Analysis of the Language, Genre and Structure of Legal Opinions
Creators: name: Tanner, Susan
Publisher: name: Carnegie Mellon University
Year: 2020
Subjects: Rhetoric

description: Rhetorical scholars have long advocated for the study of legal discourse because of the “centrality of language in the production, exercise and subversion of legal power.”[1] The law’s power comes from more than simply its force through proclamations, statutes and speech acts; it is inherent in its constitutive nature, through which courts shape and reflect individual realities and lived experiences. In this dissertation, I account for the force of legal discourse through an analysis of how courts use subtle rhetorical strategies in legal opinions to maintain legitimacy and authority and shape a common understanding of the law. Further, I seek to bring legal and rhetorical scholarship into closer concert by applying both a legal and a rhetorical analysis to multiple corpora, including an entire line of jurisprudence.Through a discourse analysis of thousands of texts, from across courts (including the US, UK and Navajo Supreme Courts) jurisdictions, and legal topics, I identify key genre features of legal opinions add to the rhetorical force of the discourse. Through a rhetorical analysis of appellate opinions, I examine the ways in which judges choose legal starting points, craft their arguments and anticipate counterarguments, and the effect these choices have on garnering acceptance of legal concepts within primary and secondary audiences. Further, I explore the promise of advocacy as a way to mediate access to the legal process. Finally, my research examines the constitutive nature of the law and attempts to explain how a body of law and its related concepts are shaped through legal discourse. To do this, I trace the inception of privacy law in the US from Warren and Brandeis' The Right to Privacy through to current legal conceptions of privacy. Among my findings are that the use of quasi-scientific reasoning and argument structures lend ethos and authority to legal arguments, and that courts use prior discourse in a highly sophisticated manner that deters discussion of legal alternatives. My research adds to an understanding of how the law is shaped by discourse and suggests a tool for non-legal experts to understand the role of prior text in contemporary decisions

description: The magnetization-dependent rectification effect in a Ge-based magnetic heterojunction was analyzed. The rectification effects were observed in heterojunctions with Curie temperature values as high as 300 K. It was found that the current rectification of the diode could be controlled either by the bias voltage or by the magnetic field.

description: We introduce the concept of multisymplectic formalism, familiar in covariant field theory, for the study of integrable defects in 1+1 classical field theory. The main idea is the coexistence of two Poisson brackets, one for each spacetime coordinate. The Poisson bracket corresponding to the time coordinate is the usual one describing the time evolution of the system. Taking the nonlinear Schrödinger (NLS) equation as an example, we introduce the new bracket associated to the space coordinate. We show that, in the absence of any defect, the two brackets yield completely equivalent Hamiltonian descriptions of the model. However, in the presence of a defect described by a frozen Bäcklund transformation, the advantage of using the new bracket becomes evident. It allows us to reinterpret the defect conditions as canonical transformations. As a consequence, we are also able to implement the method of the classical r matrix and to prove Liouville integrability of the system with such a defect. The use of the new Poisson bracket completely bypasses all the known problems associated with the presence of a defect in the discussion of Liouville integrability. A by-product of the approach is the reinterpretation of the defect Lagrangian used in the Lagrangian description of integrable defects as the generating function of the canonical transformation representing the defect conditions.

description: We have realized Bose-Einstein condensation (BEC) of 87Rb in the F=2, m_F=2 hyperfine substate in a hybrid trap, consisting of a quadrupole magnetic field and a single optical dipole beam. The symmetry axis of the quadrupole magnetic trap coincides with the optical beam axis, which gives stronger axial confinement than previous hybrid traps. After loading 2x10^6 atoms at 14 muK from a quadrupole magnetic trap into the hybrid trap, we perform efficient forced evaporation and reach the onset of BEC at a temperature of 0.5 muK and with 4x10^5 atoms. We also obtain thermal clouds of 1x10^6 atoms below 1 muK in a pure single beam optical dipole trap, by ramping down the magnetic field gradient after evaporative cooling in the hybrid trap.

Filmic Aesthetics and Technologies of War, Policy, and “Truth” in the Motion Pictures of the United States Information Agency

description: While scholars in media and cultural studies such as Saunders, Shaw, Doherty, and Iber have meaningfully investigated the relationships between Cold War politics andpopular culture, fewer works have addressed the role of government-attributed media within the larger cultural Cold War. My dissertation explores the motion pictures of theUnited States Information Agency (USIA), the nation’s primary propaganda office during the Cold War, in order to better understand how the machinery of a global agency informed filmic output and viewing cultures. Between 1953 and 1999, the USIA produced or distributed roughly 20,000 motion-picture titles, spanning 160 countries and 50 languages. However, these materials are relatively unknown to media scholars within the United States. A domestic distribution ban over the agency’s materials that extended into the 1990s has rendered these films relatively invisible.My work reconsiders prevailing assumptions regarding the “Cultural” Cold War by closely investigating the bureaucracy of the USIA and how policymakers and film producerscreated propaganda films and presented them to global audiences. The USIA motion pictures, which were primarily documentary in form, represent an eclectic collection of films that were diverse in style, tone, and messaging. My dissertation investigates five cases from 1953 to 1989, situating formalist readings of films alongside theoretical work concerning topics such as wartime imagery (Torchin, Butler, Tagg, and Lowe), the rhetorical presidency (Tudda, Parry-Giles, and Chernus), American frontier mythologies (Grandin, Jessup, and Turner), and televisual aesthetics (Gehr, Hilderbrand, and Longmore). I trace the tensions between policy, culture, technology, and economicswithin the films’ aesthetics to foster readings that argue against predominantly bipolar frameworks in the study of the cultural Cold War. My analysis primarily relies ondocumentaries released in response to active conflict. Produced and distributed with greater immediacy, these films and their paper trails more directly express specific policies and reveal the operations behind the USIA apparatuses. Furthermore, many of these documentaries also represent or capture scenes of violence, warfare, and atrocity. By linking “violence” to truth and veracity I argue that we can effectively determine the way the USIA manufactured adaptable “truths” for political necessity on the global stage. My dissertation therefore seeks to realize three goals: make visible the motion pictures and processes of this massive agency to American scholars; instantiate viablemethodologies to facilitate new and decentralized readings of the cultural Cold War; and delineate theory that helps articulate connections between filmic aesthetics andgovernmental policy and bureaucracy.
Constraining the Milky Way's Hot Gas Halo with OVII and OVII Emission Lines

description: The Milky Way hosts a hot ($\approx 2 \times 10^6$ K), diffuse, gaseous halo based on detections of z = 0 OVII and OVIII absorption lines in quasar spectra and emission lines in blank-sky spectra. Here we improve constraints on the structure of the hot gas halo by fitting a radial model to a much larger sample of OVII and OVIII emission line measurements from XMM-Newton EPIC-MOS spectra compared to previous studies ($\approx$ 650 sightlines). We assume a modified $β$-model for the halo density distribution and a constant-density Local Bubble from which we calculate emission to compare with the observations. We find an acceptable fit to the OVIII emission line observations with $χ^{2}_{red}$ (dof) = 1.08 (644) for best-fit parameters of $n_o r_c^{3β} = 1.35 \pm 0.24$ cm$^{-3}$ kpc$^{3β}$ and $β= 0.50 \pm 0.03$ for the hot gas halo and negligible Local Bubble contribution. The OVII observations yield an unacceptable $χ^{2}_{red}$ (dof) = 4.69 (645) for similar best-fit parameters, which is likely due to temperature or density variations in the Local Bubble. The OVIII fitting results imply hot gas masses of $M$(< 50 kpc) = $3.8_{-0.3}^{+0.3} \times 10^{9} M_{\odot}$ and $M$(< 250 kpc) = $4.3_{-0.8}^{+0.9} \times 10^{10} M_{\odot}$, accounting for $\lesssim$ 50% of the Milky Way's missing baryons. We also explore our results in the context of optical depth effects in the halo gas, the halo gas cooling properties, temperature and entropy gradients in the halo gas, and the gas metallicity distribution. The combination of absorption and emission line analyses implies a sub-solar gas metallicity that decreases with radius, but that also must be $\geq 0.3 Z_{\odot}$ to be consistent with the pulsar dispersion measure toward the LMC.

description: We calculate the spectral density and occupations of a system of two capacitively coupled quantum dots, each one connected to its own pair of conducting leads, in a regime of parameters in which the total coupling to the leads for each dot $Γ_i$ are different. The system has been used recently to perform pseudospin spectroscopy by controlling independently the voltages of the four leads. For an odd number of electrons in the system, $Γ_1=Γ_2$, equal dot levels $E_1=E_2$ and sufficiently large interdot repulsion $U_{12}$ the system lies in the SU(4) symmetric point of spin and pseudospin degeneracy in the Kondo regime. In the more realistic case $Γ_1 \neq Γ_2$, pseudospin degeneracy is broken and the symmetry is reduced to SU(2). Nevertheless we find that the essential features of the SU(4) symmetric case are recovered by appropriately tuning the level difference $δ=E_2-E_1$. The system behaves as an SU(4) Kondo one at low energies. Our results are relevant for experiments which look for signatures of SU(4) symmetry in the Kondo regime of similar systems.

description: The nature of chiral phase transition of massless two flavor QCD depends on the fate of flavor singlet axial symmetry $U_A(1)$ at the critical temperature ($T_c$). Assuming that a finite $U_A(1)$ breaking remains at $T_c$, the corresponding three dimensional effective theory is composed of four massless and four massive scalar fields. We study the renormalization group flow of the effective theory in the $ε$-expansion, using a mass dependent renormalization scheme, and determine the region of the attractive basin flowing into the $O(4)$ fixed point with a focus on its dependence on the size of the $U_A(1)$ breaking. The result is discussed from a perspective of the decoupling of massive fields. It is pointed out that, although the effective theory inside the attractive basin eventually reaches the $O(4)$ fixed point, the approaching rate, one of the universal exponents, is different from that of the standard $O(4)$ model. We present the reason for this peculiarity, and propose a novel possibility for chiral phase transition in two-flavor QCD.
