description: We examine a quantised massive scalar field in $(1+1)$-dimensional spatially compact cosmological spacetimes in which the early time and late time expansion laws provide distinguished definitions of Fock "in" and "out" vacua, with the possible exception of the spatially constant sector, which may become effectively massless at early or late times. We show, generalising the work of Ford and Pathinayake, that when such a massive zero mode occurs, the freedom in the respective "in" and "out" states is a family with two real parameters. As an application, we consider massive untwisted and twisted scalar fields in the $(1+1)$-dimensional spatially compact Milne spacetime, where the untwisted field has a massive "in" zero mode. We demonstrate, by a combination of analytic and numerical methods, that the choice of the massive "in" zero mode state has a significant effect on the response of an inertial Unruh-DeWitt detector, especially in the excitation part of the spectrum. The detector's peculiar velocity with respect to comoving cosmological observers has the strongest effect in the "in" vacuum of the untwisted field, where it shifts the excitation and de-excitation resonances towards higher values of the detector's energy gap.

description: Recently, the LIGO-Virgo Collaboration (LVC) concluded that there is no evidence for lensed gravitational waves (GW) in the first half of the O3 run, claiming "We find the observation of lensed events to be unlikely, with the fractional rate at $μ>2$ being $3.3\times 10^{-4}$". While we agree that the chance of an individual GW event being lensed at $μ>2$ is smaller than $10^{-3}$, the number of observed events depends on the product of this small probability times the rate of mergers at high redshift. Observational constraints from the stochastic GW background indicate that the rate of conventional mass BBH mergers (8 < M (M$_{\odot}$) < 15) in the redshift range 1

description: The present MA dissertation aims to explore the concept of urban space and its multiple dimensions through the lense of theatre production. In David Mamet’s Edmond (1982) as well as in Duncan Macmillan’s Lungs (2011), urban space, far from being a mere background to the stories, is presented as a dynamic environment that is socially produced under the corrosive influence of capitalism. The urban universe depicted in the plays seems to be precarious, deprived of any kind of constants and balance, an urban world that is ominous and disorienting. It is through the human interaction within these urban spaces that the human bodies become the recipients of various self-shaping bodily experiences that transform them and delineate their fate. As a result, the present project illustrates the essence of the urban environments and the way they have evolved, while at the same time it illuminates the way the characters’ psychological state is defined by their interaction with the urban spaces they inhabit and the way they negotiate their presence in these dynamic environments.
description: Η παρούσα μεταπτυχιακή διπλωματική εργασία έχει ως σκοπό να διερευνήσει την έννοια του αστικού πεδίου και τις πολλαπλές διαστάσεις του μέσα από το πρίσμα της θεατρικής παραγωγής. Στο έργο Έντμοντ του Ντέιβιντ Μάμετ όπως επίσης και στους Πνεύμονες του Ντάνκαν Μακμίλλαν, το αστικό πεδίο, χωρίς να αποτελεί απλά ένα υπόβαθρο για τις ιστορίες, παρουσιάζεται ως ένα δυναμικό περιβάλλον το οποίο είναι ένα κοινωνικό παράγωγο της διαβρωτικής επιρροής του καπιταλισμού. Το αστικό πεδίο που αντικατοπτρίζεται στα έργα φαντάζει επισφαλές, που στερείται κάθε είδους σταθερών και ισορροπίας, έναν αστικό κόσμο δυσοίωνο και αποπροσανατολιστικό. Μέσα από την ανθρώπινη αλληλεπίδραση που λαμβάνει χώρα στα αστικά πεδία τα ανθρώπινα σώματα γίνονται αποδέκτες σωματικών εμπειριών που τα διαμορφώνουν, τα μεταμορφώνουν και προδιαγράφουν το πεπρωμένο τους. Επομένως, η παρούσα εργασία αποτυπώνει την ουσία των αστικών πεδίων και τον τρόπο με τον οποίο αυτά έχουν εξελιχθεί, ενώ ταυτόχρονα διαφωτίζει τον τρόπο με τον οποίο η ψυχολογική κατάσταση των χαρακτήρων ορίζεται από την αλληλεπίδρασή τους με τα αστικά πεδία που κατοικούν και τον τρόπο με τον οποίο αυτοί διαπραγματεύονται την παρουσία τους σε αυτά τα δυναμικά περιβάλλοντα.

description: Holes in nanowires have drawn significant attention in recent years because of the strong spin-orbit interaction, which plays an important role in constructing Majorana zero modes and manipulating spin-orbit qubits. Here, from the strongly anisotropic leakage current in the spin blockade regime for a double dot, we extract the full g-tensor and find that the spin-orbit field is in plane with an azimuthal angle of 59° to the axis of the nanowire. The direction of the spin-orbit field indicates a strong spin-orbit interaction along the nanowire, which may have originated from the interface inversion asymmetry in Ge hut wires. We also demonstrate two different spin relaxation mechanisms for the holes in the Ge hut wire double dot: spin-flip cotunneling to the leads, and spin-orbit interaction within the double dot. These results help establish feasibility of a Ge-based quantum processor.

description: Starting from the paradigmatic spin-boson model (SBM), we investigate the static and dynamical properties of a system of two distant two-level emitters coupled to a one-dimensional Ohmic waveguide beyond the rotating wave approximation. Employing static and dynamical polaron Ansätze we study the effects of finite separation distance on the behavior of the photon-mediated Ising-like interaction, qubit frequency renormalization, ground-state magnetization, and entanglement entropy of the two-qubit system. Based on previous works we derive an effective approximate Hamiltonian for the two-impurity SBM that preserves the excitation-number and thus facilitates the analytical treatment. In particular, it allows us to introduce non-Markovianity arising from delay-feedback effects in two distant emitters in the so-called ultrastrong coupling (USC) regime. We test our results with numerical simulations performed over a discretized circuit-QED model, finding perfect agreement with previous results, and showing interesting dynamical effects arising in ultrastrong waveguide QED with distant emitters. In particular, we revisit the Fermi two-atom problem showing that, in the USC regime, initial correlations yield two different evolutions for symmetric and antisymmetric states even before the emitters become causally connected. Finally, we demonstrate that the collective dynamics, e.g., superradiance or subradiance, are affected not only by the distance between emitters, but also by the coupling, due to significant frequency renormalization. This constitutes another dynamical consequence of the USC regime.

From obligation to agreement: concepts of servitude in early modern England
Creators: name: Marple, Laura Reiko Simeon
Publisher: name: University of British Columbia
Year: 2009

description: One very popular genre of literature during the seventeenth and eighteenth centuries was advice (or prescriptive) literature, directed at husbands and wives, parents and children, masters and servants. These books provided readers with detailed descriptions of the ideal relationships between family members, and the duties attendant upon individuals in each position. They are valuable to historians in this capacity, as portrayals of desired behavior, rather than as depictions of how things actually were. The relationship between masters and servants is a particularly difficult one to understand, for servants occupied a unique place within the family. In many ways they were similar to the master’s children, for they were unmarried minors, and temporarily under his authority. Yet in other ways servants were quite different from the children of the family, for there existed between them and their masters a contract for food, wages and lodging in return for their labor. Advice literature is a valuable source of information regarding the manner in which seventeenth- and eighteenth-century individuals viewed the ambiguous relationship between master and servant. However, to date the secondary literature on servants has not made much use of advice literature, or examined its usefulness in this capacity. This thesis seeks to present a systematic examination of the prescriptive literature for servants published during the seventeenth and eighteenth centuries, comparing not only the types of advice given to servants, but also the manner in which the advice was given. It will soon be apparent that the literature evolved dramatically over the course of the two centuries, reflecting both new conceptions of the nature of servitude, as well as developments in society at large. These changes may be described as the transition from a view of servitude as a state which imposed moral obligations on the servant, to one which saw it as a period of contractual agreement between servant and master.

description: The scaling approach recently proposed by Landau and Ott for isothermal magnetization curves is extended to the average kinetic energy density of the condensate. Two low $T_c$ superconductors, Nb and $Li_{2}Pd_{3}B$ are studied and their isothermal reversible magnetization shown to display Landau and Ott scaling. Good agreement is obtained for the upper critical field $H_{c2}(T)$, determined from the Abrikosov approximation for the reversible region (standard linear extrapolation of the magnetization curve), and from the maximum of the kinetic energy curves. For the full range of data, which includes the irreversible region, the isothermal $d.M.B/H^2$ curves for $Li_2Pd_3B$ show an impressive collapse into a single curve over the entire range of field measurements. The Nb isothermal $d.M.B/H^2$ curves exhibit the interesting feature of a constant and temperature independent minimum value.
Six Large Coronal X-ray Flares Observed With Chandra

description: A study of the six largest coronal X-ray flares in the Chandra archive is presented. The flares were observed on II Peg, OU And, Algol, HR 1099, TZ CrB and CC Eri, all with the High Energy Transmission Grating spectrometer (HETG) and the ACIS detectors. We reconstruct an Emission Measure Distribution EMD(T), using a spectral line analysis method, for flare and quiescence states separately and compare the two. Subsequently, elemental abundaces are obtained from the EMD. We find similar behaviour of the EMD in all flares, namely a large high-T component appears while the low-T (kT < 2 keV) plasma is mostly unaffected, except for a small rise in the low-T Emission Measure. In five of the six flares we detect a First Ionization Potential (FIP) effect in the flare abundances relative to quiescence. This may contradict previous suggestions that flares are the cause of an inverse FIP effect in highly active coronae.

description: In this work, we present bilayer flat-band Hamiltonians, in which all bulk states are localized and specified by extensive local integrals of motion (LIOMs). The present systems are bilayer extension of Creutz ladder, which is studied previously. In order to construct models, we employ building blocks, cube operators, which are linear combinations of fermions defined in each cube of the bilayer lattice. There are eight cubic operators, and the Hamiltonians are composed of the number operators of them, the LIOMs. A suitable arrangement of locations of the cube operators is needed to have exact projective Hamiltonians. The projective Hamiltonians belong to a topological classification class, BDI class. With the open boundary condition, the constructed Hamiltonians have gapless edge modes, which commute with each other as well as the Hamiltonian. This result comes from a symmetry analogous to the one-dimensional chiral symmetry of the BDI class. These results indicate that the projective Hamiltonians describe a kind of symmetry protected topological phase matter. Careful investigation of topological indexes, such as Berry phase, string operator, is given. We also show that by using the gapless edge modes, a generalized Sachdev-Ye-Kitaev (SYK) model is constructed.

description: For a space X, we define Frobenius and Verschiebung operations on the nil-terms NA^{fd} (X) in the algebraic K-theory of spaces, in three different ways. Two applications are included. Firstly, we obtain that the homotopy groups of NA^{fd} (X) are either trivial or not finitely generated as abelian groups. Secondly, the Verschiebung defines a Z[N_x]-module structure on the homotopy groups of NA^{fd} (X), with N_x the multiplicative monoid. We also we give a calculation of the homotopy groups of the nil-terms NA^{fd} (*) after p-completion for an odd prime p as Z_p[N_x]-modules up to dimension 4p-7. We obtain non-trivial groups only in dimension 2p-2, where it is finitely generated as a Z_p[N_x]-module, and in dimension 2p-1, where it is not finitely generated as a Z_p[N_x]-module.

description: In this paper, we systematically present the high-level architectural synthesis for general wavelet-based algorithms via a model of I/O data space and the nonlinear transformations of the I/O data space. The parallel architectures synthesized in this paper are based on the computation model of distributed memory anddistributed control. Several architectural designs have been proposed for the Discrete Wavelet Transform (DWT) [4]-[11]. None of these architectural designs for computing the DWT follows a systematic data dependence and localization analysis of general wavelet-based algorithms, and thus they only serve as particular designs and cannot be extended to other complicated wavelet-based algorithms such as MultiWavelet Transform (MWT)[1,13,14], Wavelet PacketTransform (WPT)[2,15] or Spacial-Frequential Quantization (SFQ) [12]. Using the WPT as a representative example of complex wavelet-based algorithms, this paper fully describes the theory and methodology used in synthesizing parallel architectures for general wavelet-based algorithms.

description: Spin and spatial dimensionalities are universal concepts, essential for describing both phase transitions and dynamics in magnetic materials. Lately, these ideas have been adopted to describe magnetic properties of metamaterials, as well as to replicate and explore ensembles of mesospins belonging to different universality classes. Here, we take the next step by investigating magnetic metamaterials not conforming to the conventional framework of continuous phase transitions. Instead of a continuous decrease in the moment with temperature, discrete steps are possible, resulting in a binary transition in the interactions of the elements. The transition is enabled by nucleation and annihilation of vortex cores, shifting topological charges between the interior and the edges of the elements. Consequently, the mesospins can be viewed as shifting their spin dimensionality, from 2 (XY-like) to 0, (vortices) at the transition. The results provide insight into how dynamics at different length-scales couple, which can lead to thermally driven topological transitions in magnetic metamaterials.

description: The mass media play an essential role in the transmission of information, attitudes, perceptions, and beliefs. Because of that, the rules of war have changed dramatically during the last decades. The media have a tremendous capability regarding fabricating fake news and targeting specific rumours. The new face of this kind of war is called Hybrid war and is adequately described by the Gerasimov’s doctrine. The role of non-military means of achieving political and strategic goals has grown, and, in many cases, they have exceeded the power of force of weapons in their effectiveness. The information space opens extensively asymmetrical possibilities for reducing the fighting potential of enemy. In North Africa, we witnessed the use of technologies for influencing state structures and the population with the help of information networks. It is necessary to perfect activities in the information space, including the defence of our objects. On the contrary, people will not believe every single false message. Nevertheless, if the distortions and forgeries accumulate, the boundaries of what can be said and conceived are shifted. Then the extreme is considered normal. Moreover, the incredible is true; it is precisely the goal of the Gerasimov doctrine. On the other hand, the study examines the coverage of the Russian-Georgian war (South Ossetia war, 2008), through the analysis of mass news media platforms. Through the examination of primary and dominant media; RT, Washington Post (USA), BBC News (UK) websites, and the Georgian messenger are considered as significant sources to study aims for analysing the way that global news media framed the crisis in (South Ossetia war, 2008). Also, to understand the way that mass media cover disasters and conflicts, and to realize how news media succeeded to identify new dimensions in the information space and warfare. Moreover, the study attempts to determine Russia’s use of information as a tool of mischief and influence through the Gerasimov’s doctrine giving a tremendously new dimension, which changed the war landscape (NATO Strategic Communications Centre of Excellence, Svetoka, and Reynolds, 2016).

description: An ad-hoc network is a collection of wireless mobile nodeswithout the required intervention of any centralized Access Point. With the existence of the hidden terminals and the absence of the central control, the resource allocation is always a very challenging problem in such networks. In this paper, a distributed resource allocation scheme is designed for ad hoc networks, in which each mobile node dynamicallysearches its Native Index (NI) with negligible communication overhead. By utilizing the NI, the hidden terminal problem can be completely avoided in the resource allocation, and the resource can be efficiently distributed to all the nodes. The proposed resource allocation method can greatly improve the system throughput. Utilizing the method, the broadcast problem can be easily solved and QoS service (Quality of Service) can be efficiently supported.
Correlation functions for a di-neutron condensate in asymmetric nuclear matter

description: Recent calculations with an effective isospin dependent contact interaction show the possibility of the crossover from superfluidity of neutron Cooper pairs in $^1S_0$ pairing channel to Bose-Einstein condensation (BEC) of di-neutron bound states in dilute nuclear matter. The density and spin correlation functions are calculated for a di-neutron condensate in asymmetric nuclear matter with the aim to find the possible features of the BCS-BEC crossover. It is shown that the zero-momentum transfer spin correlation function satisfies the sum rule at zero temperature. In symmetric nuclear matter, the density correlation function changes sign at low momentum transfer across the BCS-BEC transition and this feature can be considered as a signature of the crossover. At finite isospin asymmetry, this criterion gives too large value for the critical asymmetry $α_c^d\sim0.9$, at which the BEC state is quenched. Therefore, it can be trusted for the description of the density-driven BCS-BEC crossover of neutron pairs only at small isospin asymmetry. This result generalizes the conclusion of the study in Phys. Rev. Lett. {\bf 95}, 090402 (2005), where the change of sign of the density correlation function at low momentum transfer in two-component quantum fermionic atomic gas with the balanced populations of fermions of different species was considered as an unambiguous signature of the BCS-BEC transition.

description: We study the influence of boundary conditions on self-affine random functions u(t) in the interval t/L \in [0,1], with independent Gaussian Fourier modes of variance ~ 1/q^α. We consider the probability distribution of the mean square width of u(t) taken over the whole interval or in a window t/L \in [x, x+δ]. Its characteristic function can be expressed in terms of the spectrum of an infinite matrix. This distribution strongly depends on the boundary conditions of u(t) for finite δ, but we show that it is universal (independent of boundary conditions) in the small-window limit. We compute it directly for all values of α, using, for α<3, an asymptotic expansion formula that we derive. For α> 3, the limiting width distribution is independent of α. It corresponds to an infinite matrix with a single non-zero eigenvalue. We give the exact expression for the width distribution in this case. Our analysis facilitates the estimation of the roughness exponent from experimental data, in cases where the standard extrapolation method cannot be used

description: Quantum Fourier Transform (QFT) plays a principal role in the development of efficient quantum algorithms. Since the number of quantum bits that can currently built is limited, while many quantum technologies are inherently three- (or more) valued, we consider extending the reach of the realistic quantum systems by building a QFT over ternary quantum digits. Compared to traditional binary QFT, the q-valued transform improves approximation properties and increases the state space by a factor of (q/2)n. Further, we use non-binary QFT derivation to generalize and improve the approximation bounds for QFT.

description: (Abridged) With the SMA we have made high angular-resolution (~1" = 160 AU) observations of the protobinary system IRAS 16293-2422 in the J = 4-3 lines of HCN and HC^15N, and in the continuum at 354.5 GHz. The HCN (4-3) line was also observed using the JCMT to supply missing short spacing information. Submillimeter continuum emission is detected from the individual binary components with a separation of ~5". The HC^15N (4-3) emission has revealed a compact (~500 AU) flattened structure (P.A. = -16 degree) associated with Source A, and shows a velocity gradient along the projected minor axis, which can be interpreted as an infalling gas motion. Our HCN image including the short-spacing information shows an extended (~3000 AU) circumbinary envelope as well as the compact structure associated with Source A. A toy model consisting of a flattened structure with radial infall towards a 1 Msun central star reproduces the HCN/HC^15N position-velocity diagram along the minor axis of the HC^15N emission. In the extended envelope there is also a North-East (Blue) to South-West (Red) velocity gradient across the binary alignment, which is likely to reflect gas motion in the swept-up dense gas associated with the molecular outflow from Source A. At Source B, there is only a weak compact structure with much narrower line widths (~2 km/s) seen in the optically-thin HC^15N emission than that at Source A (>10 km/s), and there is no clearly defined bipolar molecular outflow associated with Source B. These results imply the different evolutionary stages between Source A and B in the common circumbinary envelope.

Mutual Chern-Simons Theory of Spontaneous Vortex Phase

description: We apply the mutual Chern-Simons effective theory (Phys. Rev. B 71, 235102) of the doped Mott insulator to the study of the so-called spontaneous vortex phase in the low-temperature pseudogap region, which is characterized by strong unconventional superconducting fluctuations. An effective description for the spontaneous vortex phase is derived from the general mutual Chern-Simons Lagrangian, based on which the physical properties including the diamagnetism, spin paramagnetism, magneto-resistance, and the Nernst coefficient, have been quantitatively calculated. The phase boundaries of the spontaneous vortex phase which sits between the onset temperature $T_{v}$ and the superconducting transition temperature $T_{c}$, are also determined within the same framework. The results are consistent with the experimental measurements of the cuprates.

Cosmic rays from the knee to the second knee: 10^14 to 10^18 eV

description: The energies of cosmic rays, fully ionized charged nuclei, extend over a wide range up to 10^20 eV. A particularly interesting energy region spans from 10^14 to 10^18 eV, where the all-particle energy spectrum exhibits two interesting structures, the 'knee' and the 'second knee'. An explanation of these features is thought to be an important step in understanding of the origin of the high-energy particles. Recent results of air shower experiments in this region are discussed. Special attention is drawn to explain the principle of air shower measurements - a simple Heitler model of (hadronic) air showers is developed.

No-thinning simulations of extensive air showers and small scale fluctuations at the ground level

description: The particle density in extensive air showers fluctuates at the ground level. These fluctuations, at the scale of the scintillator detector size (several meters), lead to the diversity of the individual detector responses. Therefore, small scale fluctuations contribute to the error in the estimation of the primary energy by a ground array. This contribution is shown to be non-Gaussian. The impact on the primary energy spectrum measured by a ground array is estimated. Ir is argued that super-GZK events observed by AGASA experiment do not result from the energy overestimation, due to small scale fluctuations, of lower energy events.

Probing the Randall-Sundrum geometric origin of flavor with lepton flavor violation

description: The ``anarchic'' Randall-Sundrum model of flavor is a low energy solution to both the electroweak hierarchy and flavor problems. Such models have a warped, compact extra dimension with the standard model fermions and gauge bosons living in the bulk, and the Higgs living on or near the TeV brane. In this paper we consider bounds on these models set by lepton flavor violation constraints. We find that loop-induced decays of the form l->l'+gamma are ultraviolet sensitive and uncalculable when the Higgs field is localized on a four-dimensional brane; this drawback does not occur when the Higgs field propagates in the full five-dimensional space-time. We find constraints at the few TeV level throughout the natural range of parameters, arising from muon-electron conversion in the presence of nuclei, rare muon decays, and rare tau decays. A "tension" exists between loop-induced dipole decays such as mu->e+gamma and tree-level processes such as muon-electron conversion; they have opposite dependences on the five-dimensional Yukawa couplings, making it difficult to decouple flavor-violating effects. We emphasize the importance of the future experiments MEG and PRIME. These experiments will definitively test the Randall-Sundrum geometric origin of hierarchies in the lepton sector at the TeV-scale.

description: The aim of the present thesis was the translation of the theatrical play Les sept jours de Simon Labrosse, si ça vous interesse (the title in English: Seven days in the life of Simon Labrosse, just in case you’re interested), written by the Canadian writer Carole Frechette. In the same time, we tried to approach the play itself, its language, as well as the social circumstances of the period in which it was written. Furthermore, we analyzed the writer herself and her style. Then, the French text is juxtaposed with its Greek translation, so that all the choices can be evaluated. Finally, there are the comments of several parts of the theatrical text, concerning vocabulary, curses, terminology that is found in the text and also comments on pragmatics. The paper ends with some conclusions conducted during the translation of the theatrical text.
