description: We show that the null Melvin map applied to a rotational isometry of global anti-de Sitter space produces a spacetime with properties analogous to both the Godel and Schrodinger geometries. The isometry group of this Godel-Schrodinger spacetime is appropriate to provide a holographic dual for the same non-relativistic conformal theory as the ordinary Schrodinger geometry, but defined on a sphere. This spacetime also possesses closed timelike curves outside a certain critical radius. We show that a holographic preferred screen for an observer at the origin sits at an interior radius, suggesting that a holographic dual description would only require the chronologically consistent region. Additionally, giant graviton probe branes experience repulson-type instabilities in the acausal region, suggesting a condensation of branes will modify the pathological part of the geometry to remove the closed timelike curves.

description: Using a sample of BzK-selected galaxies at z~2 identified from the CFHT/WIRCAM near-infrared survey of GOODS-North, we discuss the relation between star formation rate (SFR), specific star formation rate (SSFR), and stellar mass (M_{*}), and the clustering of galaxies as a function of these parameters. For star-forming galaxies (sBzKs), the UV-based SFR, corrected for extinction, scales with the stellar mass as SFR ~ M_{*}^{alpha} with alpha = 0.74+/-0.20 down to M_{*} ~ 10^{9} M_{solar}, indicating a weak dependence on the stellar mass of the SSFR. We also measure the angular correlation function and hence infer the correlation length for sBzK galaxies as a function of M_{*}, SFR, and SSFR, as well as K-band apparent magnitude. We show that passive galaxies (pBzKs) are more strongly clustered than sBzK galaxies at a given stellar mass, mirroring the color-density relation seen at lower redshifts. We also find that the correlation length of sBzK galaxies ranges from 4 to 20 h^{-1}Mpc, being a strong function of M_{K}, M_{*}, and SFR. On the other hand, the clustering dependence on SSFR changes abruptly at 2x10^{-9} yr^{-1}, which is the typical value for "main sequence" star-forming galaxies at z~2. We show that the correlation length reaches a minimum at this characteristic value, and is larger for galaxies with both smaller and larger SSFRs; a dichotomy that is only marginally implied from the predictions of the semi-analytical models. Our results suggest that there are two types of environmental effects at work at z~2. Stronger clustering for relatively quiescent galaxies implies that the environment has started to play a role in quenching star formation. At the same time, stronger clustering for galaxies with elevated SSFRs ("starbursts") might be attributed to an increased efficiency for galaxy interactions and mergers in dense environments.

description: We show that the relativistic motion of a quantum system can be used to generate quantum gates. The nonuniform acceleration of a cavity is used to generate well-known two-mode quantum gates in continuous variables. Observable amounts of entanglement between the cavity modes are produced through resonances which appear by repeating periodically any trajectory.

description: In this work, we present a rather simple method to study the Casimir effect on a spherical shell for a massless scalar field with Dirichlet boundary condition by applying the indefinite metric field (Krein) quantization technique. In this technique, the field operators are constructed from both negative and positive norm states. Having understood that negative norm states are un-physical, they are only used as a mathematical tool for renormalizing the theory and then one can get rid of them by imposing some proper physical conditions.

description: We investigate composite two Higgs doublet models realized as pseudo Goldstone modes, generated through the spontaneous breaking of a global symmetry due to strong dynamic at the TeV scale. A detailed comparative survey of two possible symmetry breaking patterns, SU(5) -> SU(4) x U(1) and SU(5) x SU(4), is made. We point out choices for the Standard Model fermion representations that can alleviate some phenomenological constraints, with emphasis towards a simultaneous solution of anomalous Zb\bar{b} coupling and Higgs mediated Flavor Changing Neutral Currents. We also write down the kinetic lagrangian for several models leading to Two Higgs Doublets and identify the anomalous contributions to the T parameter. Moreover, we describe a model based on the breaking $SO(9)/SO(8)$ in which there is no tree-level breaking of custodial symmetry, discussing also the possible embeddings for the fermion fields.

description: We study analytically and numerically the dynamical Casimir effect in a cavity containing two stationary 2-level atoms that interact with the resonance field mode via the Tavis-Cummings Hamiltonian. We determine the modulation frequencies for which the field and atomic excitations are generated and study the corresponding dynamical behaviors in the absence of damping. It is shown that the two-atom setup allows for monitoring of photon generation without interrupting the growth, and different entangled states can be generated during the process.

description: The CMS collaboration has recently conducted a search for trijet resonances in multi-jet events at the LHC. Motivated in part by this analysis, we examine the phenomenology of exotic particles transforming under higher representations of SU(3) color, focusing on those representations which intrinsically prohibit decays to fewer than three jets. We determine the LHC discovery reach for a particle transforming in a representation of this sort and discuss several additional theoretical and phenomenological constraints which apply to such a particle. Furthermore, we demonstrate that such a particle can provide a consistent explanation for a trijet excess (an invariant-mass peak of roughly 375 GeV) observed in the recent CMS study.

description: We have performed a systematic study of the effects of field strength and quenched disorder on the driven dynamics of square artificial spin ice. We construct a network representation of the configurational phase space, where nodes represent the microscopic configurations and a directed link between node i and node j means that the field may induce a transition between the corresponding configurations. In this way, we are able to quantitatively describe how the field and the disorder affect the connectedness of states and the reversibility of dynamics. In particular, we have shown that for optimal field strengths, a substantial fraction of all states can be accessed using external driving fields, and this fraction is increased by disorder. We discuss how this relates to control and potential information storage applications for artificial spin ices.

description: Lockdown-Lockerungen trotz bereits wieder steigender Corona-Infektionszahlen und der langsame Impffortschritt schicken die deutsche Wirtschaft auf einen Stop-and-Go-Kurs. Auf Öffnungsschritte müssen wohl mindestens regional immer wieder Schließungen folgen, um das Infektionsgeschehen im Griff zu behalten. Die Industrie zeigt sich vor allem wegen des guten Auslandsgeschäfts insgesamt robust. In den Dienstleistungsbranchen wird die Erholung nach einem erneuten Rücksetzer zum Jahresbeginn allerdings schleppend verlaufen. Wohl erst im Laufe des dritten Quartals werden die gesellschaftlichen und wirtschaftlichen Einschränkungen nachhaltig zurückgefahren werden können. Nachdem noch im Dezember des vergangenen Jahres ein Wachstum der Wirtschaftsleistung von 5,3 Prozent im Jahr 2021 realistisch erschien, liegt die aktuelle Prognose mit 3,0 Prozent deutlich niedriger. Für 2022 sind derzeit 3,8 Prozent zu erwarten. Unklar sind bisher die wirtschaftlichen Langzeitfolgen der Corona-Pandemie: Beispielsweise bei den Unternehmensinsolvenzen wird sich das Ausmaß frühestens im Laufe dieses Jahres zeigen.

description: We analyze the quench dynamics of a one-dimensional bosonic Mott insulator and focus on the time evolution of density correlations. For these we identify a pronounced propagation front, the velocity of which, once correctly extrapolated at large distances, can serve as a quantitative characteristic of the many-body Hamiltonian. In particular, the velocity allows the weakly interacting regime, which is qualitatively well described by free bosons, to be distinguished from the strongly interacting one, in which pairs of distinct quasiparticles dominate the dynamics. In order to describe the latter case analytically, we introduce a general approximation to solve the Bose-Hubbard Hamiltonian based on the Jordan-Wigner fermionization of auxiliary particles. This approach can also be used to determine the ground-state properties. As a complement to the fermionization approach, we derive explicitly the time-dependent many-body state in the noninteracting limit and compare our results to numerical simulations in the whole range of interactions of the Bose-Hubbard model.

description: For many of the unsolved problems concerning cycles and matchings in graphs it is known that it is sufficient to prove them for \emph{snarks}, the class of nontrivial 3-regular graphs which cannot be 3-edge coloured. In the first part of this paper we present a new algorithm for generating all non-isomorphic snarks of a given order. Our implementation of the new algorithm is 14 times faster than previous programs for generating snarks, and 29 times faster for generating weak snarks. Using this program we have generated all non-isomorphic snarks on $n\leq 36$ vertices. Previously lists up to $n=28$ vertices have been published. In the second part of the paper we analyze the sets of generated snarks with respect to a number of properties and conjectures. We find that some of the strongest versions of the cycle double cover conjecture hold for all snarks of these orders, as does Jaeger's Petersen colouring conjecture, which in turn implies that Fulkerson's conjecture has no small counterexamples. In contrast to these positive results we also find counterexamples to eight previously published conjectures concerning cycle coverings and the general cycle structure of cubic graphs.

description: Das Wiederaufflammen des Pandemiegeschehens und die erneuten Lockdowns haben zwar den Erholungskurs der Weltwirtschaft abgebremst, doch die Einbußen werden insgesamt weniger gravierend sein als nach der ersten Infektionswelle im Frühjahr. Vor allem die Industrie entwickelt sich weiterhin gut. Einzelhandel und viele Dienstleistungen sind dagegen stark belastet – vor allem in besonders betroffenen Regionen wie Europa. Die finanzpolitischen Impulse federn aber einen Großteil der Verwerfungen ab. Mit steigendem Impfschutz werden ab der zweiten Jahreshälfte die meisten wirtschaftlichen Einschränkungen sukzessive wieder aufgehoben, was den privaten Konsum beleben dürfte. Das DIW Berlin hebt die Prognose aufgrund der kräftigen konjunkturellen Dynamik in den USA und China für dieses und das kommende Jahr um jeweils 0,4 Prozentpunkte an und rechnet mit einem Wachstum von 6,7 beziehungsweise 4,8 Prozent. Ihren langfristigen Wachstumspfad wird die globale Produktion wohl erst wieder Ende 2022 erreichen. Auch wenn sich durch das Brexit-Abkommen und die Abwahl des US-Präsidenten Donald Trump einige weltwirtschaftliche Unwägbarkeiten gelegt haben, bestehen weiterhin Risiken, vor allem durch erneute Infektionswellen und stark steigende Insolvenzzahlen.

description: Motivated by studies of typical properties of quantum states in statistical mechanics, we introduce phase-random states, an ensemble of pure states with fixed amplitudes and uniformly distributed phases in a fixed basis. We first show that canonical states typically appear in subsystems of phase-random states. We then investigate the simulatability of phase-random states, which is directly related to that of time evolution in closed systems, by studying their entanglement properties. We find that starting from a separable state, time evolutions under Hamiltonians composed of only separable eigenstates generate extremely high entanglement and are difficult to simulate with matrix product states. We also show that random quantum circuits consisting of only two-qubit diagonal unitaries can generate an ensemble with the same average entanglement as phase-random states.

The fate of emerging contaminants in wastewater treatment plants
Creators: name: Simhon, Michal Vered
Publisher: name: University of British Columbia
Year: 2014

description: Potential risk and toxicity of emerging contaminants (ECs) on the human population and the surrounding ecosystem have led to growing concern in the scientific world. This class of contaminants includes a variety of commonly used compounds such as pharmaceuticals and personal care products, as well as industry-based compounds such as surfactants and plasticizers. There are many challenges involved when studying these contaminants with the most apparent one relating to the lack of a standardized analytical method. As a result, this research investigated and optimized an analytical method for the determination of selected EC compounds in the soluble and particulate fractions of samples collected from the wastewater treatment pilot plant located at the University of British Columbia, Vancouver, Canada. Once the method was optimized, the effects of hydraulic retention time (HRT) and solids retention time (SRT) on the fate of ECs through the wastewater treatment process were studied using the UBC membrane biological nutrient removal pilot plant. The study involving the HRT failed to provide sufficient evidence to adequately assess the observed effects, since an inadequate quantity of each contaminant was spiked into the pilot plant. However, the spiking quantity was adjusted for the individual contaminants based on these observations, enabling the effect of the SRT to be studied. All analytes exhibited one of two trends during the mass balance analysis. For all of the EC compounds that were studied, sorption to the mixed liquor particulates and washout in the effluent were not the only removal mechanisms in the experimental system of the UBC pilot plant.

description: We show that for a normal locally-${\mathscr P}$ space $X$ (where ${\mathscr P}$ is a topological property subject to some mild requirements) the subset $C_{\mathscr P}(X)$ of $C_b(X)$ consisting of those elements whose support has a neighborhood with ${\mathscr P}$, is a subalgebra of $C_b(X)$ isometrically isomorphic to $C_c(Y)$ for some unique (up to homeomorphism) locally compact Hausdorff space $Y$. The space $Y$ is explicitly constructed as a subspace of the Stone--Čech compactification $βX$ of $X$ and contains $X$ as a dense subspace. Under certain conditions, $C_{\mathscr P}(X)$ coincides with the set of those elements of $C_b(X)$ whose support has ${\mathscr P}$, it moreover becomes a Banach algebra, and simultaneously, $Y$ satisfies $C_c(Y)=C_0(Y)$. This includes the cases when ${\mathscr P}$ is the Lindelöf property and $X$ is either a locally compact paracompact space or a locally-${\mathscr P}$ metrizable space. In either of the latter cases, if $X$ is non-${\mathscr P}$, $Y$ is non-normal, and $C_{\mathscr P}(X)$ fits properly between $C_0(X)$ and $C_b(X)$; even more, we can fit a chain of ideals of certain length between $C_0(X)$ and $C_b(X)$. The known construction of $Y$ enables us to derive a few further properties of either $C_{\mathscr P}(X)$ or $Y$. Specifically, when ${\mathscr P}$ is the Lindelöf property and $X$ is a locally-${\mathscr P}$ metrizable space, we show that \[\dim C_{\mathscr P}(X)=\ell(X)^{\aleph_0},\] where $\ell(X)$ is the Lindelöf number of $X$, and when ${\mathscr P}$ is countable compactness and $X$ is a normal space, we show that \[Y=\mathrm{int}_{βX}\upsilon X\] where $\upsilon X$ is the Hewitt realcompactification of $X$.

description: The technique of generating families produces obstructions to the existence of embedded Lagrangian cobordisms between Legendrian submanifolds in the symplectizations of 1-jet bundles. In fact, generating families may be used to construct a TQFT-like theory that, in addition to giving the aforementioned obstructions, yield structural information about invariants of Legendrian submanifolds. For example, the obstructions devised in this paper show that there is no generating family compatible Lagrangian cobordism between the Chekanov-Eliashberg Legendrian $m(5_2)$ knots. Further, the generating family cohomology groups of a Legendrian submanifold restrict the topology of a Lagrangian filling. Structurally, the generating family cohomology of a Legendrian submanifold satisfies a type of Alexander duality that, when the Legendrian is null-cobordant, can be seen as Poincaré duality of the associated Lagrangian filling. This duality implies the Arnold Conjecture for Legendrian submanifolds with linear-at-infinity generating families. The results are obtained by developing a generating family version of wrapped Floer cohomology and establishing long exact sequences that arise from viewing the the spaces underlying these cohomology groups as mapping cones.

description: Landform diversity has been identified as one means to support biodiversity in the face of rising temperatures. The aim of this research is to show methods forresearchers to measure the capability of urban landscapes in safeguardingfauna against the impacts of rising temperatures. A case study of Wellington, New Zealand, shows that 1276 ha of the landscape under study consist of south-facing slopescapable of supporting fauna that are historically adapted to the cool climatic conditions. Approximately 425 ha of this area have an overlap with indigenous land cover classes that are believed to be primary habitats for fauna.

The influence of spatial and temporal climate variation on species' distributions, phenologies and interactions
Creators: name: Kharouba, Heather Marie
Publisher: name: University of British Columbia
Year: 2013

description: With climate change, species are shifting their distributions polewards and upwards, and advancing their phenologies. However, there is substantial interspecific variation in these responses and ecologists are having difficulty explaining why. Understanding this variation is critical as it is likely to lead to widespread consequences for trophic interactions and ecological communities. In this thesis, I test several hypotheses concerning the causes and ecological consequences of interspecific and intertaxonomic variation in climate-distribution and phenology-temperature relationships. First, I tested and found support for the hypothesis that species from different taxonomic groups vary in the strength of climate-distribution relationships, likely because of differences in their life history strategies. However, my results suggest that dispersal ability is unlikely to be the key trait affecting species' geographic distributions at broad scales. Across broad-scales, I found that butterfly and plant phenologies were strongly affected by temperature, suggesting that phenological shifts in response to future climate change are likely to be widespread. Flight season timing of early-season butterfly species and those with lower dispersal ability was more sensitive to temperature than later-season species and those with greater dispersal ability, suggesting that ecological traits can account for some of the interspecific variation in phenological sensitivity to temperature. Differences in phenological sensitivities of butterflies and plants to temperature imply that shifts in phenological synchrony are likely and could be substantial for interacting species, potentially resulting in important fitness consequences. Finally, experimentally warming the egg masses and larvae of the western tent caterpillar (Malacosoma californicum pluviale) placed on the branches of its host plant, red alder (Alnus rubra), in the field led to opposing direct and indirect effects on larval development. Warming significantly advanced larval but not leaf emergence, which initially prolonged larval development. However, once leaves were present, warming accelerated larval development, resulting in no overall effects on larval development. Taken together, this thesis demonstrates that to understand the full implications of climate change for species and communities, accounting for species' life history strategies and interactions will be essential. However, without more quantitative estimates of the fitness consequences of shifts in phenological synchrony, this understanding will be limited.

description: Pristine stars with masses between ~140 and 260 M_sun are theoretically predicted to die as pair-instability supernovae. These very massive progenitors could come from Pop III stars in the early universe. We model the light curves and spectra of pair-instability supernovae over a range of masses and envelope structures. At redshifts of reionization z >= 6, we calculate the rates and detectability of pair-instability and core collapse supernovae, and show that with the James Webb Space Telescope, it is possible to determine the contribution of Pop III and Pop II stars toward reionization by constraining the stellar initial mass function at that epoch using these supernovae. We also find the rates of Type Ia supernovae, and show that they are not rare during reionization, and can be used to probe the mass function at 4-8 M_sun. If the budget of ionizing photons was dominated by contributions from top-heavy Pop III stars, we predict that the bright end of the galaxy luminosity function will be contaminated by pair-instability supernovae.

description: Die Europäische Kommission steht vor der Herausforderung und Chance, den Green Deal umzusetzen und dabei gleichzeitig die Erholung der Wirtschaft infolge der Corona-Krise einzuleiten. Investitionen in die Transformation zur Klimaneutralität der Grundstoffindustrie spielen dabei eine zentrale Rolle, da der Sektor für 16 Prozent des CO2-Ausstoßes der EU verantwortlich und zentral für nachgelagerte Wertschöpfungsketten ist. Während oftmals über die Förderung der Investitionsmöglichkeiten diskutiert wird, sind für die Transformation aber vor allem klare Rahmenbedingungen notwendig, mit denen Investitionen in klimafreundliche Technologien erst wirtschaftlich werden und die sicherstellen, dass Unternehmen die Investitionen in die Transformation auch umsetzen. Dafür müssen dann auch die notwendige Infrastruktur und Institutionen bereitgestellt werden. Damit diese Maßnahmen rechtzeitig und koordiniert umgesetzt werden, ist es wichtig, auf nationaler und europäischer Ebene Ziele für den Anteil an CO2-neutraler Produktion zu setzen und diese im Klimaschutzgesetz und der EU-Governancestruktur zu verankern.

description: There is sufficient evidence to show that both humans and fauna are profoundly affected by landscape pattern composition and configuration in relation to adaptation to climate change impacts in urban landscapes. Despite this, global-scale research that ranks which components of landscape pattern play the most pivotal roles in this process is absent. Also lacking is in-depth examination of the potential areas of conflict between biodiversity conservation targets and those that pertain to human dimensions of climate change adaptation goals in relation to landscape patterns. The research aim was to determine how to identify, rank, and weight the most important components of landscape pattern affecting urban biodiversity in the changing climate and how to address areas of conflict between biodiversity conservation and human dimensions of climate change adaptation goals in terms of the spatial patterning of land cover classes distributed across urban landscapes. To do this, a global survey of 87 participants from 69 academic centres involved in at least 325 research projects between 2000 and 2017 was conducted. Of the eight components of landscape pattern identified and ranked by participants worldwide, the three most important components are respectively patch size, connectivity and proximity, and land cover heterogeneity. This research reveals that opinions of participants with experience in conducting research in the Southern Hemisphere in general and Oceania in particular influence this ranking. While a range of recommendations from specialists have been gathered and weighted, there is still much more research required to address areas of conflict between what fauna and humans need in the face of climate change.

description: We examine the distribution of transition discs as a function of mm flux. We confirm that as expected in any model in which most primordial discs turn into transition discs and in which mm flux declines with time, transition discs have lower mm fluxes on average than primordial discs. However, we find that the incidence of transition discs does not, as expected, fall monotonically towards large mm fluxes and we investigate the hypothesis that these mm bright transition discs may have a distinct physical origin. We find that mm bright transition discs occupy a separate region of parameter space. Transition discs in the bright mm sub-sample have systematically higher accretion rates and inner hole radii than those in the faint mm sub-sample, along with being systematically weighted to earlier spectral types.

description: For a fixed natural number n, we consider a family of rank n unitary perturbations of a completely non-unitary contraction (cnu) with deficiency indices (n,n) on a separable Hilbert space. We relate the unitary dilation of such a contraction to its rank n unitary perturbations. Based on this construction, we prove that the spectra of the perturbed operators are purely singular if and only if the operator-valued characteristic function corresponding to the unperturbed operator is inner. In the case where n=1 the latter statement reduces to a well-known result in the theory of rank one perturbations. However, our method of proof via the theory of dilations extends to the case of arbitrary n. We find a formula for the operator-valued characteristic functions corresponding to a family of related cnu contractions. In the case where n=1, the characteristic function of the original contraction we obtain a simple expression involving the normalized Cauchy transform of a certain measure. An application of this representation then enables us to control the jump behavior of this normalized Cauchy transform "across" the unit circle.
