description: While wormhole spacetimes are predictions of the general theory of relativity, specific solutions may not be compatible with quantum field theory. This paper modifies the charged wormhole model of Kim and Lee with the aim of satisfying an extended version of a quantum inequality due to Ford and Roman. The modified metric may be viewed as a solution of the Einstein field equations representing a charged wormhole that is compatible with quantum field theory.

Ginzburg-Landau phase diagram for dense matter with axial anomaly, strange quark mass, and meson condensation

description: We discuss the phase structure of dense matter, in particular the nature of the transition between hadronic and quark matter. Calculations within a Ginzburg-Landau approach show that the axial anomaly can induce a critical point in this transition region. This is possible because in three-flavor quark matter with instanton effects a chiral condensate can be added to the color-flavor locked (CFL) phase without changing the symmetries of the ground state. In (massless) two-flavor quark matter such a critical point is not possible since the corresponding color superconductor (2SC) does not break chiral symmetry. We study the effects of a nonzero but finite strange quark mass which interpolates between these two cases. Since at ultra-high density the first reaction of CFL to a nonzero strange quark mass is to develop a kaon condensate, we extend previous Ginzburg-Landau studies by including such a condensate. We discuss the fate of the critical point systematically and show that the continuity between hadronic and quark matter can be disrupted by the onset of a kaon condensate. Moreover, we identify the mass terms in the Ginzburg-Landau potential which are needed for the 2SC phase to occur in the phase diagram.

description: Neutron-star and black-hole X-ray binaries (XRBs) exhibit radio jets, whose properties depend on the X-ray spectral state and history of the source. In particular, black-hole XRBs emit compact, steady radio jets when they are in the so-called hard state, the jets become eruptive as the sources move toward the soft state, disappear in the soft state, and re-appear when the sources return to the hard state. On the other hand, jets from neutron-star X-ray binaries are typically weaker radio emitters than the black-hole ones at the same X-ray luminosity and in some cases radio emission is detected in the soft state. Significant phenomenology has been accumulated so far regarding the spectral states of neutron-star and black-hole XRBs, and there is general agreement about the type of the accretion disk around the compact object in the various spectral states. Our aim is to investigate whether the phenomenology regarding the X-ray emission on one hand and the jet appearance and disappearance on the other can be put together in a consistent physical picture. It has been shown that the so-called Poynting-Robertson Cosmic Battery (PRCB) explains in a natural way the formation of magnetic fields in the disks of AGN and the ejection of jets. We investigate whether the PRCB can also explain the formation, destruction, and variability of jets in XRBs. We find excellent agreement between the conditions under which the PRCB is efficient (i.e., the type of the accretion disk) and the emission or destruction of the radio jet. The disk-jet connection in XRBs is explained in a natural way using the PRCB.

description: The metastable vapor-liquid coexistence of short-range attractive fluids hinders the formation of crystal nuclei, which in turn makes difficult the progress of the system towards its vapor-solid ground state. In this letter we show that crystal growth can be assisted by imposing temperature fluctuations. By so doing the obtained solid is nearly a fcc monocrystal in contrast with the extreme polycrystalline structure obtained at low temperatures. The study is carried out by combining the replica exchange Monte Carlo method and the standard slab technique. The obtained results suggest a pathway for growing coherent crystals from the metastable liquid. This is particularly relevant for the crystallization of globular proteins.

Out with the old-school : exploring women hockey players' sport leadership perceptions and intentions
Creators: name: Cumming, Donna Michelle
Publisher: name: University of British Columbia
Year: 2022

description: The underrepresentation of women in sport leadership roles is recognized by researchers as a significant barrier to achieving gender equity in sport (Burton & Leberman, 2017a). This issue is even more prevalent in male-dominated sports such as ice hockey, where women represent less than 5% of coaches in Canada (Hockey Canada, 2020). While there is extensive research that documents the barriers and supports for women in sport leadership, few studies have examined this issue from the perspective of potential future sport leaders, namely varsity women athletes. Further, no existing research has explored this topic in a Canadian hockey-specific context. Using semi-structured interviews and focus groups, this study explored 11 Canadian varsity women hockey players’ perceptions of and experiences with sport leadership, as well as their intentions to pursue sport leadership roles after graduation. A critical feminist lens was applied to consider how and to what extent the athletes’ gendered experiences impacted their sport leadership intentions and perceptions. After engaging in a reflexive thematic analysis, the findings of this study were categorized into three main themes. The first theme contextualized participants’ perceptions and experiences with sport leadership through an in-depth review of the women athletes’ experiences growing up in a male-dominated hockey setting. The second theme examined participants’ (gendered) perceptions and experiences with sport leadership, revealing an overall preference for interpersonal and athlete-centered leadership styles. Further, this theme demonstrated the impact of the athletes’ current and past sport leaders on their own beliefs and values in relation to sport and sport leadership. The third theme outlined the athletes’ calculated intentions to pursue sport leadership, describing how they expressed an interest in pursuing sport leadership, but rarely as a top priority. Additionally, this theme identified gendered implications related to the athletes’ intentions to pursue sport leadership, suggesting that sport leadership was often a lower priority for the participants due to a lack of opportunities for women in many hockey leadership environments.

description: Disentangling the processes leading populations to extinction is a major topic in ecology and conservation biology. The difficulty to find a mate in many species is one of these processes. Here, we investigate the impact of self-incompatibility in flowering plants, where several inter-compatible classes of individuals exist but individuals of the same class cannot mate. We model pollen limitation through different relationships between mate availability and fertilization success. After deriving a general stochastic model, we focus on the simple case of distylous plant species where only two classes of individuals exist. We first study the dynamics of such a species in a large population limit and then, we look for an approximation of the extinction probability in small populations. This leads us to consider inhomogeneous random walks on the positive quadrant. We compare the dynamics of distylous species to self-fertile species with and without inbreeding depression, to obtain the conditions under which self-incompatible species could be less sensitive to extinction while they can suffer more pollen limitation.
Enhanced photon-assisted spin transport in a quantum dot attached to ferromagnetic leads

description: We investigate real-time dynamics of spin-polarized current in a quantum dot coupled to ferromagnetic leads in both parallel and antiparallel alignments. While an external bias voltage is taken constant in time, a gate terminal, capacitively coupled to the quantum dot, introduces a periodic modulation of the dot level. Using non equilibrium Green's function technique we find that spin polarized electrons can tunnel through the system via additional photon-assisted transmission channels. Owing to a Zeeman splitting of the dot level, it is possible to select a particular spin component to be photon-transfered from the left to the right terminal, with spin dependent current peaks arising at different gate frequencies. The ferromagnetic electrodes enhance or suppress the spin transport depending upon the leads magnetization alignment. The tunnel magnetoresistance also attains negative values due to a photon-assisted inversion of the spin-valve effect.

The delta-quantum machine, the k-model, and the non-ordinary spatiality of quantum entities
Creators: name: de Bianchi, Massimiliano Sassoli
Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The purpose of this article is threefold. Firstly, it aims to present, in an educational and non-technical fashion, the main ideas at the basis of Aerts' creation-discovery view and hidden measurement approach: a fundamental explanatory framework whose importance, in this author's view, has been seriously underappreciated by the physics community, despite its success in clarifying many conceptual challenges of quantum physics. Secondly, it aims to introduce a new quantum-machine - that we call the delta-quantum-machine - which is able to reproduce the transmission and reflection probabilities of a one-dimensional quantum scattering process by a Dirac delta-function potential. The machine is used not only to demonstrate the pertinence of the above mentioned explanatory framework, in the general description of physical systems, but also to illustrate (in the spirit of Aerts' epsilon-model) the origin of classical and quantum structures, by revealing the existence of processes which are neither classical nor quantum, but irreducibly intermediate. We do this by explicitly introducing what we call the k-model and by proving that its processes cannot be modelized by a classical or quantum scattering system. The third purpose of this work is to exploit the powerful metaphor provided by our quantum-machine, to investigate the intimate relation between the concept of potentiality and the notion of non-spatiality, that we characterize in precise terms, introducing for this the new concept of process-actuality.

description: We describe a new method to identify young, late-type stars within ~150 pc of the Earth that employs visual or near-infrared data and the GALEX GR4/5 database. For spectral types later than K5, we demonstrate that the ratio of GALEX near-ultraviolet (NUV) to visual and near-IR emission is larger for stars with ages between 10 and 100 Myr than for older, main sequence stars. A search in regions of the sky encompassing the TW Hya and Scorpius-Centaurus Associations has returned 54 high-quality candidates for followup. Spectroscopic observations of 24 of these M1-M5 objects reveal Li 6708 angstrom absorption in at least 17 systems. Because GALEX surveys have covered a significant fraction of the sky, this methodology should prove valuable for future young star studies.

Shattered temporalities : an investigation into trauma, time, and the monstrous in Maria Dahvana Headley’s The mere wife (2018)
Creators: name: Kloosterman, Alison
Publisher: name: University of British Columbia
Year: 2022

description: This thesis offers a close reading of The Mere Wife (2018), Maria Dahvana Headley’s modernized adaptation of the Old English epic Beowulf. I argue that the monstrous, most immediately represented by the characters Dana Mills and Gren, is a social construction concealing cultural anxieties and the desire to preserve a sociocultural status quo. The characters who dwell within the gated suburban community attempt to preserve a status quo, treating those outside of the community, namely Dana Mills and Gren, as monstrous. However, in the dynamic of the novel, the monstrous is not simply what is excluded from the gated suburban community, but also something instantiated and veiled within it. I argue that the repudiation of the monstrous aims at preserving a suburban, homogenous, straight, and white sociocultural identity, but this very attempt at repudiation leads to this sociocultural identity’s annihilation, and reveals a monstrosity already lurking within the culturally specific status quo. I also argue that most of the characters initially judged as monstrous carry marginalized intersections of identity such as being Queer, feminine, racialized, lower class, and traumatized. I take particular interest in the ways that manifestations of trauma, when paired with these marginalized intersections of identity, are pathologized by the dwellers in suburban Herot and reduced to the monstrous, whereas their traumatized counterparts, who do not share these marginalized intersections of identity, do not suffer the same stigmatization. I analyze the temporally fragmented realities of the traumatized individual embodied in the monstrous, with particular attention to the work of Robert Stolorow, Richard Kearney, and Cathy Caruth.

description: We study a single polaron in the Su-Schrieffer-Heeger (SSH) model using four different techniques (three numerical and one analytical). Polarons show a smooth crossover from weak to strong coupling, as a function of the electron-phonon coupling strength $λ$, in all models where this coupling depends only on phonon momentum $q$. In the SSH model the coupling also depends on the electron momentum $k$; we find it has a sharp transition, at a critical coupling strength $λ_c$, between states with zero and nonzero momentum of the ground state. All other properties of the polaron are also singular at $λ= λ_c$, except the average number of phonons in the polaronic cloud. This result is representative of all polarons with coupling depending on $k$ and $q$, and will have important experimental consequences (eg., in ARPES and conductivity experiments).

description: We study sigma models in AdS_4 with global N=1 supersymmetry and find that they differ significantly from their flat-space cousins -- the target space is constrained to be a Kahler manifold with an exact Kahler form, the superpotential transforms under Kahler transformations, the space of supersymmetric vacua is generically a set of isolated points even when the superpotential vanishes, and the R-symmetry is classically broken by the cosmological constant. Remarkably, the exactness of the Kahler class is also required for the sigma model to arise as a decoupling limit of N=1 supergravity, and ensures the vanishing of gravitational anomalies. As simple applications of these results, we argue that fields with AdS_4 scale masses are ubiquitous in, for example, type IIB N=1 AdS_4 vacua stabilized near large volume; we also show that the Affleck-Dine-Seiberg runaway of N_f < N_c SQCD is regulated by considering the theory in AdS_4.

Migrations et traumatismes : Afrique, Caraïbes, océan Indien
Creators: name: Booluck-Miller, Pooja
Publisher: name: University of British Columbia
Year: 2022

description: Migration as a topic in Francophone literature has long been subjected to unidirectional approaches which fail to provide a holistic image of such a complex journey. Driven by the urge to not only consider geopolitical or sociological contexts but also how they influence the psychological disposition of migrant characters, this dissertation explores the role of trauma studies in migration literature. It studies how female authors, through the mimetic function of representation, use the individual experiences of characters to reveal the lived reality of migration trauma. The literary analysis of six postcolonial novels by Ken Bugul (Senegal), Léonora Miano (Cameroon), Gisèle Pineau (Guadeloupe), Nathacha Appanah (Mauritius), and Shenaz Patel (Mauritius) speak of the involuntary and voluntary displacement of migrant characters in three different geographical spaces. Drawing on theories such as Michel Foucault’s Heterotopia and Dori Laub’s contributions on individual and collective trauma, this study demonstrates how the notion of “third space” and “in-betweenness” exacerbates the traumatic pain experienced by migrants and, subsequently, future generations. In addition, the works of Marianne Hirsch on postmemory demonstrate how exiles and refugees from the Chagos and Comoros Islands (as depicted in Appanah’s and Patel’s novels) relive the traumatic symptoms of their ancestors, thus demonstrating the consequences of intergenerational trauma. Lastly, I question the hesitance of employing psychoanalytic theories in Francophone postcolonial studies to illustrate their utility and contributions in understanding the psychic and mental dispositions of migrant characters. I thus propose to integrate findings from psychoanalysis in literary studies to underline how some manifestations of trauma, governed by the unconscious, play a role in the migrant’s journey. The questions driving the literary analysis of all the novels studied are as follows: How do female authors give voice to the underrepresented migrant population? How does the notion of “race” influence an African, Caribbean and Indo-oceanic migrant’s migration experience? What resources are present to migrants facing a permanent state of alienation which in some cases, leads to traumatic symptoms? In short, this dissertation demonstrates the omnipresence of trauma in selected characters’ migration journeys and how this mental disposition renders an already cumbersome journey an even greater challenge.

description: We report the discovery of seven strongly lensed Lyman break galaxy (LBG) candidates at z~7 detected in Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) imaging of Abell 1703. The brightest candidate, called A1703-zD1, has an observed (lensed) magnitude of 24.0 AB (26 sigma) in the WFC3/IR F160W band, making it 0.2 magnitudes brighter than the z_850-dropout candidate recently reported behind the Bullet Cluster and 0.7 magnitudes brighter than the previously brightest known z~7.6 galaxy, A1689-zD1. With a cluster magnification of ~9, this source has an intrinsic magnitude of H_160 = 26.4 AB, a strong z_850 - J_125 break of 1.7 magnitudes, and a photometric redshift of z~6.7. Additionally, we find six other bright LBG candidates with H_160 band magnitudes of 24.9-26.4, photometric redshifts z~6.4 - 8.8, and magnifications mu~3-40. Stellar population fits to the ACS, WFC3/IR, and \Spitzer/IRAC data for A1703-zD1 and A1703-zD4 yield stellar masses (0.7 - 3.0) x 10^{9} M_sun, stellar ages 5-180 Myr, and star-formation rates ~7.8 M_sun/yr, and low reddening with A_V <= 0.7. The source-plane reconstruction of the exceptionally bright candidate A1703-zD1 exhibits an extended structure, spanning ~4 kpc in the z~6.7 source plane, and shows three resolved star-forming knots of radius r~0.4 kpc.

description: An analytical expression is obtained for the biexciton binding energy as a function of the inter-exciton distance and binding energy of constituent quasi-one-dimensional excitons in carbon nanotubes. This allows one to trace biexciton energy variation and relevant non-linear absorption under external conditions whereby the exciton binding energy varies. The non-linear absorption lineshapes calculated exhibit characteristic asymmetric (Rabi) splitting as the exciton energy is tuned to the nearest interband plasmon resonance. These results are useful for tunable optoelectronic device applications of optically excited semiconducting carbon nanotubes, including the strong excitation regime with optical non-linearities.

description: The spread of methicillin-resistant Staphylococcus aureus (MRSA) in the community, hospitals and in livestock is mediated by highly diverse virulence factors that include secreted toxins, superantigens, enzymes and surface-associated adhesins allowing host adaptation and colonization. Here, we combined proteogenomics, secretome and phenotype analyses to compare the secreted virulence factors in selected S. aureus isolates of the dominant human- and livestock-associated genetic lineages CC8, CC22, and CC398. The proteogenomic comparison revealed 2181 core genes and 1306 accessory genes in 18 S. aureus isolates reflecting the high genome diversity. Using secretome analysis, we identified 869 secreted proteins with 538 commons in eight isolates of CC8, CC22, and CC398. These include 64 predicted extracellular and 37 cell surface proteins that account for 82.4% of total secretome abundance. Among the top 10 most abundantly secreted virulence factors are the major autolysins (Atl, IsaA, Sle1, SAUPAN006375000), lipases and lipoteichoic acid hydrolases (Lip, Geh, LtaS), cytolytic toxins (Hla, Hlb, PSMβ1) and proteases (SspB). The CC398 isolates showed lower secretion of cell wall proteins, but higher secretion of α- and β-hemolysins (Hla, Hlb) which correlated with an increased Agr activity and strong hemolysis. CC398 strains were further characterized by lower biofilm formation and staphyloxanthin levels because of decreased SigB activity. Overall, comparative secretome analyses revealed CC8- or CC22-specific enterotoxin and Spl protease secretion as well as Agr- and SigB-controlled differences in exotoxin and surface protein secretion between human-specific and zoonotic lineages of S. aureus.

description: For arbitrary networks of random masses connected by random springs, we define a general strong disorder real-space renormalization (RG) approach that generalizes the procedures introduced previously by Hastings [Phys. Rev. Lett. 90, 148702 (2003)] and by Amir, Oreg and Imry [Phys. Rev. Lett. 105, 070601 (2010)] respectively. The principle is to eliminate iteratively the elementary oscillating mode of highest frequency associated with either a mass or a spring constant. To explain the accuracy of the strong disorder RG rules, we compare with the Aoki RG rules that are exact at fixed frequency.

description: In neutral atom quantum computers, readout and preparation of the atomic qubits are usually based on fluorescence imaging and subsequent analysis of the acquired image. For each atom site, the brightness or some comparable metric is estimated and used to predict the presence or absence of an atom. Across different setups, we can see a vast number of different approaches used to analyze these images. Often, the choice of detection algorithm is either not mentioned at all or it is not justified. We investigate several different algorithms and compare their performance in terms of both precision and execution run time. To do so, we rely on a set of synthetic images across different simulated exposure times with known occupancy states. Since the use of simulation provides us with the ground truth of atom site occupancy, we can easily state precise error rates and variances of the reconstructed property. To also rule out the possibility of better algorithms existing, we calculated the Cramér-Rao bound in order to establish an upper limit that even a perfect estimator cannot outperform. As the metric of choice, we used the number of photonelectrons that can be contributed to a specific atom site. Since the bound depends on the occupancy of neighboring sites, we provide the best and worst cases, as well as a half filled one. Our comparison shows that of our tested algorithms, a global non-linear least-squares solver that uses the optical system's PSF to return a each sites' number of photoelectrons performed the best, on average crossing the worst-case bound for longer exposure times. Its main drawback is its huge computational complexity and, thus, required calculation time. We manage to somewhat reduce this problem, suggesting that its use may be viable. However, our study also shows that for cases where utmost speed is required, simple algorithms may be preferable.

description: Abstract:
The purpose of the current study was to examine and compare the quality of the mother-adolescent relationship, the prevalence of bullying and cyberbullying perpetration and victimization, and the prevalence of externalizing behaviors, as well as the relationship among these constructs, in a clinical and a nonclinical sample of adolescents. It tested a series of hypotheses focused on group differences in the mother-adolescent relationship, peer victimization, and externalizing behaviors (i.e. deviant behaviors and bullying perpetration) for the clinical and nonclinical samples. It also tested the relationships between the mother-adolescent relationship and peer victimization, deviant behaviors, and bullying perpetration, and whether these links varied in the clinical versus non-clinical samples. Multiple regressions were used to test the first three hypotheses, while path analyses were used to test the latter hypotheses. Findings provide evidence that adolescents in the clinical group reported significantly closer relationships with their mothers and lower levels of externalizing behaviors; no differences were found in the likelihood of experiencing peer victimization. Maternal support was a negative predictor of peer victimization, and maternal support and monitoring were negative predictors of deviant behaviors and bullying perpetration. These links were invariant across clinical versus non-clinical samples.

description: Quantum Monte Carlo simulations were carried out for the system of a magnetic trimer on a metal surface. The magnetic trimer is arranged in two geometric configurations, viz., isosceles and equilateral triangles. The calculated spectral density and magnetic susceptibility show the existence of two phases: Yosida-Kondo dominant phase and magnetic frustration dominant phase. Furthermore, a critical transition between these two phases can be induced by changing the configuration of the magnetic trimers from isosceles to equilateral triangle.

Not all allies are created equal : a relational examination of allied relationships for women of color at work
Creators: name: Bhattacharyya, Barnini
Publisher: name: University of British Columbia
Year: 2022

description: In recent years, allyship has been lauded as a solution to support marginalized individuals and dismantle oppressive structures, illustrated by increasing discourse around being a “good ally” in workplaces. While allyship research suggests having work allies can help marginalized employees such as women of color navigate the workplace, traditional allyship scholarship has tended to frame allyship as a general set of overarching behaviours without delineating the nuances of different forms of ally behaviours. Further, allyship has been defined as a relationship between a marginalized person and a demographically dissimilar individual with a dominant identity who advocates on behalf of the marginalized person. This definition may not reflect the reality of marginalized group members as it does not explain how they forge beneficial ally relationships within or outside of their social groups, especially with members of other marginalized groups. Integrating scholarship on positive relationships at work (PRW) with critical intersectional perspectives on allies for women of color, I examine allyship from a relational perspective to uncover what constitutes a “good ally” and what kind of allyships women of color forge at work. Through an inductive qualitative examination of allyship using interviews with 30 dyads of women of color and their workplace allies (for a total of 60 informants), I provide a framework of intersectional allyship that challenges traditional notions of allyship and moves our understanding forward by proposing four key dimensions of allyship behaviours and three types of allied relationships at work. This framework also explicates gaps that exist between allyships expected by women of color vis-à-vis allyship as enacted by allies, thus highlighting challenges in allied practices and relationships.

description: The recent release of the First Fermi-LAT Source Catalog solidified the predominant association of extragalactic gamma-ray emitters to active galaxies, in particular blazars. A tight connection between AGN jet kinematics and gamma-ray properties has been argued for, attributing the energetic emission from active galaxies to their highly relativistic outflows. We investigate the Caltech-Jodrell Bank flat-spectrum (CJF) sample to study the connection between AGN jet kinematics and their gamma-ray properties. The high number of sources included in the sample, in addition to the excellent kinematic data available, allows us to investigate the origin of gamma-ray emission in AGN. We identify the CJF sources detected in gamma-rays (by Fermi-LAT and EGRET). We use gamma-ray luminosities and the available VLBI kinematic data to look for correlations between gamma-ray and kinematic properties, as well as for differences between AGN classes (quasars, BL Lacs, radio galaxies). We also check the kinematics of the TeV sources in the CJF. 21.8% of the CJF has been detected in the gamma-rays. We find the detectability of BL Lacs significantly higher compared to quasars. gamma-detected sources show a wider apparent jet velocity distribution compared to the non-detected ones, but the maxima of both distributions are at similar values. No strong link between gamma-ray detectability and fast apparent jet speeds is found. A tentative correlation is found between gamma-ray luminosity and maximum apparent jet speeds, stronger for BL Lac and gamma-variable sources. We find non-radial jet motions to be important to gamma-ray emission. We suggest two-zone, spine-sheath, models as a possible explanation to our results. We find 2 out of 4 CJF TeV sources show superluminal jet speeds, in contrast to previous studies.
