description: GRB 060505 was the first well-observed nearby possible long-duration GRB that had no associated supernova. Here we present spatially resolved spectra of the host galaxy of GRB 060505, an Sbc spiral, at redshift z=0.0889. The GRB occurred inside a star-forming region in the northern spiral arm at 6.5 kpc from the center. From the position of the emission lines, we determine a maximum rotational velocity for the galaxy of v~212km/s corresponding to a mass of 1.14x10^11 M_solar within 11 kpc from the center. By fitting single-age spectral synthesis models to the stellar continuum, we derive a very young age for the GRB site, confirmed by photometric and Halpha line measurements, of around 6 Myr which corresponds to the lifetime of a 32 M_solar star. The metallicity derived from several emission line measurements is lowest at the GRB site with 1/5 Z_solar but roughly solar in the rest of the galaxy. Using the 2dF galaxy redshift survey we can locate the host galaxy in its large scale (Mpc) environment. The galaxy lies in the foreground of a filamentary overdensity extending south west from the galaxy cluster Abell 3837 at z=0.0896. The properties of the GRB site are similar to those found for other long-duration GRB host galaxies with high specific star formation rate and low metallicity, which is an indication that GRB 060505 originated from a young massive star that died without making a supernova.

description: We present a measurement scheme for observing the Berry phase in a flux assisted Cooper pair pump - the Cooper pair sluice. In contrast to the recent experiments, in which the sluice was employed to generate accurate current through a resistance, we consider a device in a superconducting loop. This arrangement introduces a connection between the pumped current and the Berry phase accumulated during the adiabatic pumping cycles. From the adiabaticity criterion, we derive equations for the maximum pumped current and optimize the sluice accordingly. These results apply also to the high accuracy pumping which results in a potential candidate for a metrological current standard. For measuring the pumped current, an additional Josephson junction is installed into the superconducting loop. We show in detail that the switching of this system from superconducting state into normal state as a consequence of an external current pulse through it may be employed to probe the pumped current. The experimental realization of our scheme would be the first observation of the Berry phase in superconducting circuits.

description: In this paper, we present a comprehensive, in-depth survey of the literature on reinforcement learning approaches to decision optimization problems in a typical ridesharing system. Papers on the topics of rideshare matching, vehicle repositioning, ride-pooling, routing, and dynamic pricing are covered. Most of the literature has appeared in the last few years, and several core challenges are to continue to be tackled: model complexity, agent coordination, and joint optimization of multiple levers. Hence, we also introduce popular data sets and open simulation environments to facilitate further research and development. Subsequently, we discuss a number of challenges and opportunities for reinforcement learning research on this important domain.
Bi-branes: Target Space Geometry for World Sheet topological Defects

description: We establish that the relevant geometric data for the target space description of world sheet topological defects are submanifolds - which we call bi-branes - in the product M1 x M2 of the two target spaces involved. Very much like branes, they are equipped with a vector bundle, which in backgrounds with non-trivial B-field is actually a twisted vector bundle. We explain how to define Wess-Zumino terms in the presence of bi-branes and discuss the fusion of bi-branes. In the case of WZW theories, symmetry preserving bi-branes are shown to be biconjugacy classes. The algebra of functions on a biconjugacy class is shown to be related, in the limit of large level, to the partition function for defect fields. We finally indicate how the Verlinde algebra arises in the fusion of WZW bi-branes.

description: Quantum technology has made tremendous strides over the past two decades with remarkable advances in materials engineering, circuit design and dynamic operation. In particular, the integration of different quantum modules has benefited from hybrid quantum systems, which provide an important pathway for harnessing the different natural advantages of complementary quantum systems and for engineering new functionalities. This review focuses on the current frontiers with respect to utilizing magnetic excitatons or magnons for novel quantum functionality. Magnons are the fundamental excitations of magnetically ordered solid-state materials and provide great tunability and flexibility for interacting with various quantum modules for integration in diverse quantum systems. The concomitant rich variety of physics and material selections enable exploration of novel quantum phenomena in materials science and engineering. In addition, the relative ease of generating strong coupling and forming hybrid dynamic systems with other excitations makes hybrid magnonics a unique platform for quantum engineering. We start our discussion with circuit-based hybrid magnonic systems, which are coupled with microwave photons and acoustic phonons. Subsequently, we are focusing on the recent progress of magnon-magnon coupling within confined magnetic systems. Next we highlight new opportunities for understanding the interactions between magnons and nitrogen-vacancy centers for quantum sensing and implementing quantum interconnects. Lastly, we focus on the spin excitations and magnon spectra of novel quantum materials investigated with advanced optical characterization.

A random walk approach to quantum algorithms
Creators: name: Kendon, Viv
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The development of quantum algorithms based on quantum versions of random walks is placed in the context of the emerging field of quantum computing. Constructing a suitable quantum version of a random walk is not trivial: pure quantum dynamics is deterministic, so randomness only enters during the measurement phase, i.e., when converting the quantum information into classical information. The outcome of a quantum random walk is very different from the corresponding classical random walk, due to interference between the different possible paths. The upshot is that quantum walkers find themselves further from their starting point on average than a classical walker, and this forms the basis of a quantum speed up that can be exploited to solve problems faster. Surprisingly, the effect of making the walk slightly less than perfectly quantum can optimize the properties of the quantum walk for algorithmic applications. Looking to the future, with even a small quantum computer available, development of quantum walk algorithms might proceed more rapidly than it has, especially for solving real problems.

description: Liquid foam flows in a Hele-Shaw cell were investigated. The plug flow obtained for a monodisperse foam is strongly perturbed in the presence of bubbles whose size is larger than the average bubble size by an order of magnitude at least. The large bubbles migrate faster than the mean flow above a velocity threshold which depends on its size. We evidence experimentally this new instability and, in case of a single large bubble, we compare the large bubble velocity with the prediction deduced from scaling arguments. In case of a bidisperse foam, an attractive interaction between large bubbles induces segregation and the large bubbles organize themselves in columns oriented along the flow. These results allow to identify the main ingredients governing 2D polydisperse foam flows.

description: Probing optical excitations with high resolution is important for understanding their dynamics and controlling their interaction with other photonic elements. This can be done using state-of-the-art electron microscopes, which provide the means to sample optical excitations with combined meV--sub-nm energy--space resolution. For reciprocal photonic systems, electrons traveling in opposite directions produce identical signals, while this symmetry is broken in nonreciprocal structures. Here, we theoretically investigate this phenomenon by analyzing electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) in structures consisting of magnetically biased InAs as an instance of gyrotropic nonreciprocal material. We find that the spectral features associated with excitations of InAs films depend on the electron propagation direction in both EELS and CL, and can be tuned by varying the applied magnetic field within a relatively modest sub-tesla regime. The magnetic field modifies the optical field distribution of the sampled resonances, and this in turn produces a direction-dependent coupling to the electron. The present results pave the way to the use of electron microscope spectroscopies to explore the near-field characteristics of nonreciprocal systems with high spatial resolution.

description: We examine patterns of variation of 32 primarily main sequence stars, extending our previous 7-12 year time series to 13-20 years by combining b, y data from Lowell Observatory with similar data from Fairborn Observatory. Parallel chromospheric Ca II H and K emission data from the Mount Wilson Observatory span the entire interval. The extended data strengthen the relationship between chromospheric and photometric variation derived previously. Twenty-seven stars are deemed variable. On a year-to-year timescale young active stars become fainter when their Ca II emission increases while older less active stars such as the Sun become brighter when their Ca II emission increases. The Sun's total irradiance variation, scaled to the b and y filter photometry, still appears to be somewhat smaller than stars in our limited sample with similar mean chromospheric activity, but we now regard this discrepancy as probably due mainly to our limited stellar sample

description: Purpose: To update and extend the Carleton Laboratory for Radiotherapy Physics (CLRP) Eye Plaque (EP) dosimetry database for low-energy photon-emitting brachytherapy sources using egs_brachy, an open-source EGSnrc application. The previous database, CLRP_EPv1, contained datasets for the Collaborative Ocular Melanoma Study (COMS) plaques (2008). The new database, CLRP EPv2, consists of newly-calculated 3D dose distributions for 17 plaques [8 COMS, 5 Eckert & Ziegler BEBIG, and 4 other representative models] for Pd-103, I-125, and Cs-131 seeds. Methods: Plaque models are developed with egs_brachy, based on published/manufacturer dimensions and material data. The BEBIG plaques are identical in dimensions to COMS plaques but differ in elemental composition and/or density. Eye plaques and seeds are simulated at the centre of full-scatter water phantoms, scoring in (0.05 cm)^3 voxels spanning the eye for scenarios: (i) HOMO: simulated TG43 conditions; (ii) HETERO: eye plaques and seeds fully modelled; (iii) HETsi (BEBIG only): one seed is active at a time with other seed geometries present but not emitting photons (inactive). For validation, doses are compared to those from CLRP_EPv1 and published data. Data Format and Access: Data are available at https://physics.carleton.ca/ clrp/eye_plaque_v2, http://doi.org/10.22215/clrp/EPv2. The data consist of 3D dose distributions (text-based EGSnrc 3ddose file) and graphical presentations of the comparisons to previously published data. Potential Applications: The CLRP EPv2 database provides accurate reference 3D dose distributions to advance ocular brachytherapy dose evaluations. The fully-benchmarked eye plaque models will be freely-distributed with egs brachy, supporting adoption of model-based dose evaluations as recommended by TG-129, TG-186, and TG-221.

description: We investigate the influence of an electromagnetic environment, characterized by a finite impedance $Z(ω)$, on the Kondo effect in quantum dots. The circuit voltage fluctuations couple to charge fluctuations in the dot and influence the spin exchange processes transferring charge between the electrodes. We discuss how the low-energy properties of a Kondo quantum dot subject to dynamical Coulomb blockade resemble those of Kondo impurities in Luttinger liquids. Using previous knowledge based on the bosonization of quantum impurity models, we show that low-voltage conductance anomalies appear at zero temperature. The conductance can vanish at low temperatures even in presence of a screened impurity spin. Moreover, the quantitative determination of the corresponding Kondo temperature depends on the full frequency-dependent impedance of the circuit. This is demonstrated by a weak-coupling calculation in the Kondo interaction, taking into account the full distribution $P(E)$ of excited environmental modes.

The effect of inhomogeneous expansion on the supernova observations

description: We consider an inhomogeneous but spherically symmetric Lemaitre-Tolman-Bondi model to demonstrate that spatial variations of the expansion rate can have a significant effect on the cosmological supernova observations. A model with no dark energy but a local Hubble parameter about 15% larger than its global value fits the supernova data better than the homogeneous model with the cosmological constant. The goodness of the fit is not sensitive to inhomogeneities in the present-day matter density, and our best fit model has Omega_M ~ 0.3, in agreement with galaxy surveys. We also compute the averaged expansion rate, defined by the Buchert equations, of the best fit model and show explicitly that there is no average acceleration.

title: Seeking ontological security in the Horn of Africa : biographical narratives and imagining peace in Ethiopia’s engagement in Somalia
Creators: name: Newbery, Katharina Mathilde Bettine
Publisher: name: University of St Andrews
Year: 2019

description: In the Horn of Africa prevailing ideas of the state continue to be heavily contested both within and across formal borders. This thesis explores how the post-1991 Ethiopian government has given meaning to the Ethiopian state as an international actor, and how the state identity narratives with which it does so have shaped its entanglement with the state (re)construction process in Somalia. It contributes to the literature on international politics in the Horn of Africa by drawing attention to the role that state identity narratives play in assessing threats to the state and creating horizons and boundaries of engagement. The thesis builds on an analytical framework that combines a focus on biographical narratives with an ontological security perspective to readdress the identity/foreign policy nexus as a field of enquiry in International Relations. It foregrounds self-identification narratives rather than the mechanism of othering, and captures the sustained political efforts that have gone into maintaining and adapting biographical narratives to establish a sense of ontological security for Ethiopia as a distinct polity and international actor. Based on a discourse analysis of Ethiopian government representations over the period 1995 to 2016, this thesis argues that the government’s dominant biographical narrative has created existential boundaries of the state that necessitate an active engagement in the Horn of Africa, and has shaped how it has perceived threats to, and has sought security for, the Ethiopian state in relation to political developments in Somalia. The thesis concludes that while the Ethiopian government has been able to maintain a stable link between its identification of Ethiopia as a regional force for peace and its engagement in Somalia, it has been unable to resolve deeper tensions resulting from the way it imagines Somalia as a future state, because to do so would undermine its own foundational narratives

description: New MMT/Hectospec spectroscopy centered on the galaxy cluster A2626 and covering a ${\sim} 1.8\,\text{deg}^2$ area out to $z \sim 0.46$ more than doubles the number of galaxy redshifts in this region. The spectra confirm four clusters previously identified photometrically. A2625, which was previously thought to be a close neighbor of A2626, is in fact much more distant. The new data show six substructures associated with A2626 and five more associated with A2637. There is also a highly collimated collection of galaxies and galaxy groups between A2626 and A2637 having at least three and probably four substructures. At larger scales, the A2626--A2637 complex is not connected to the Pegasus--Perseus filament.

description: Στην παρούσα διδακτορική διατριβή αξιοποιούμε έννοιες από την υλική μηχανική, θεμελιωτές της οποίας υπήρξαν οι Eshelby και Maugin, στη μη-γραμμική θεωρία συνεχώς κατανεμημένων εξαρθρώσεων. Αφού δώσουμε τις βασικές έννοιες από τη μη-γραμμική θεωρία της ελαστικότητας και των εξαρθρώσεων συνοπτικά παρουσιάζουμε το πλαίσιο της υλικής μηχανικής. Το πλαίσιο αυτό εφαρμόζεται σε υλικώς ομοιόμορφα ανομοιoγενή σώματα. Για τα σώματα αυτά βγαίνει το συμπέρασμα ότι οι εξισώσεις ορμής και υλικής ορμής είναι ταυτότητα η μία της άλλης με την έννοια ότι έχουν το ίδιο σύνολο λύσεων. Καινούργιες εξισώσεις, λοιπόν, χρειάζονται για την επίλυση δυναμικών προβλημάτων. Προβλημάτων, δηλαδή, όπου το πεδίο των ατελειών δύναται να μεταβάλλεται κατά την διάρκεια του φαινομένου. Τις νέες αυτές εξισώσεις παράγουμε σε μία γενικευμένη εξίσωση διατήρησης της ενέργειας απαιτώντας αναλλοιωσιμότητα αυτής υπό κατάλληλους μετασχηματισμούς. Στις νέες αυτές εξισώσεις υπεισέρχεται ένα νέο είδος δυνάμεων. Καλούμε τις δυνάμεις αυτές υλικές-υλικές και είναι όλες εκείνες οι υλικές αναδιατάξεις που οδηγούν σε τοπολογικές αλλαγές στο σώμα μας. Επίσης, για την περίπτωση σωμάτων με στάσιμες εξαρθρώσεις δίνουμε τρία παραδείγματα σωμάτων υποκείμενα σε αντιεπίπεδη διάτμηση
description: In this thesis we use ideas from the theory of material mechanisms to the non-linear continuum theory of dislocations. After giving the general notions from the non-linear theory of elasticity and the theory fo dislocations we delineate the framework of material mechanisms. This framework is adapted to materially uniform but inhomogeneous materials. For this kind of materials in turns out that momentum and material momentum equations are identical in the sense that they have the same set of solutions. Therefore, new equations are needed in order to solve dynamical problems. We derive these equations starting from a generalized balance of energy and by postulating that this is invariant under a suitable group of transormations. These new equations constitute the balance law for a new kind of forces that we call material-material forces. These forces are all those material changes that take place in the body and affect its topology. Also, for the case of stationary dislocations we give three paradigms of bodies subjected to antiplane shear

description: Recent data protection regulations (such as GDPR and CCPA) grant consumers various rights, including the right to access, modify or delete any personal information collected about them (and retained) by a service provider. To exercise these rights, one must submit a verifiable consumer request proving that the collected data indeed pertains to them. This action is straightforward for consumers with active accounts with a service provider at the time of data collection, since they can use standard (e.g., password-based) means of authentication to validate their requests. However, a major conundrum arises from the need to support consumers without accounts to exercise their rights. To this end, some service providers began requiring such accountless consumers to reveal and prove their identities (e.g., using government-issued documents, utility bills, or credit card numbers) as part of issuing a verifiable consumer request. While understandable as a short-term cure, this approach is cumbersome and expensive for service providers as well as privacy-invasive for consumers. Consequently, there is a strong need to provide better means of authenticating requests from accountless consumers. To achieve this, we propose VICEROY, a privacy-preserving and scalable framework for producing proofs of data ownership, which form a basis for verifiable consumer requests. Building upon existing web techniques and features, VICEROY allows accountless consumers to interact with service providers, and later prove that they are the same person in a privacy-preserving manner, while requiring minimal changes for both parties. We design and implement VICEROY with emphasis on security/privacy, deployability and usability. We also thoroughly assess its practicality via extensive experiments.

Superreaction: the collective enhancement of a reaction rate by molecular polaritons in the presence of energy fluctuations

description: Recent experiments have demonstrated that molecular polaritons, hybrid states of light and matter formed by the strong coupling between molecular electronic or vibrational excitations and an optical cavity, can substantially modify the physical and chemical properties of molecular systems. Here, we show that, by exploiting the collective character of molecular polaritons in conjunction with the effect of polaron decoupling, i.e., the suppression of environmental influence on the polariton, a superreaction can be realized, involving a collective enhancement of charge or excitation-energy transfer reaction rate in a system of donors all coupled to a common acceptor. This effect is analogous to the phenomenon of superradiation. Since the polariton is a superposition state of excitations of all the molecules coupled to the cavity, it is vulnerable to the effect of decoherence caused by energy fluctuations in molecular systems. Consequently, in the absence of a strong light-matter interaction, the reaction rate decreases significantly as the number of molecules increases, even if the system starts from the polariton state. By turning on the light-matter interaction, the dynamic behavior of the system changes dramatically, and the reaction rate increases with the number of molecules, as expected for a superreaction. The underlying mechanism is shown to be the enhancement of quantum coherence between different donors as the light-matter interaction becomes stronger.

description: Categories provide a coarse grained description of the world. A fundamental question is whether categories simply mirror an underlying structure of nature, or instead come from the complex interactions of human beings among themselves and with the environment. Here we address this question by modelling a population of individuals who co-evolve their own system of symbols and meanings by playing elementary language games. The central result is the emergence of a hierarchical category structure made of two distinct levels: a basic layer, responsible for fine discrimination of the environment, and a shared linguistic layer that groups together perceptions to guarantee communicative success. Remarkably, the number of linguistic categories turns out to be finite and small, as observed in natural languages.
