description: The thermal freeze-out mechanism in its classical form is tightly connected to physics beyond the Standard Model around the electroweak scale, which has been the target of enormous experimental efforts. In this work we study a dark matter model in which freeze-out is triggered by a strong first-order phase transition in a dark sector, and show that this phase transition must also happen close to the electroweak scale, i.e.~in the temperature range relevant for gravitational wave searches with the LISA mission. Specifically, we consider the spontaneous breaking of a $U(1)^\prime$ gauge symmetry through the vacuum expectation value of a scalar field, which generates the mass of a fermionic dark matter candidate that subsequently annihilates into dark Higgs and gauge bosons. In this set-up the peak frequency of the gravitational wave background is tightly correlated with the dark matter relic abundance, and imposing the observed value for the latter implies that the former must lie in the milli-Hertz range. A peculiar feature of our set-up is that the dark sector is not necessarily in thermal equilibrium with the Standard Model during the phase transition, and hence the temperatures of the two sectors evolve independently. Nevertheless, the requirement that the universe does not enter an extended period of matter domination after the phase transition, which would strongly dilute any gravitational wave signal, places a lower bound on the portal coupling that governs the entropy transfer between the two sectors. As a result, the predictions for the peak frequency of gravitational waves in the LISA band are robust, while the amplitude can change depending on the initial dark sector temperature.

description: We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-tantalum diselenide by means of Electron Energy-Loss Spectroscopy and density functional theory. Our observations are consistent with a filling of the conduction band as indicated by a substantial decrease of the plasma frequency in experiment and theory. In addition, elastic scattering clearly points to a destruction of the CDW upon intercalation as can be seen by a vanishing of the corresponding superstructures. This is accompanied by a new superstructure, which can be attributed to the intercalated potassium. Based on the behavior of the c-axis upon intercalation we argue in favor of interlayer-sites for the alkali-metal and that the lattice remains in the 2H-modification.

Sweltsa hoffmani

description: Sweltsa hoffmani Kondratieff & Kirchner. Grubbs (2004) reported a single population of Sweltsa onkos (Ricker) from Yellow Birch Ravine Nature Preserve in Crawford County, Indiana. Several populations of Sweltsa have since been found in ravine streams extending westward to within ca. 60 km of the Illinois border. Kondratieff & Kirchner (2009) recently described a new species, S. hoffmani, whose distribution is mainly in unglaciated landscapes to the south and west of S. onkos. Although most of our Indiana Sweltsa specimens are nymphs and females, several males have been identified as S. hoffmani and we feel confident that S. onkos does not occur in Indiana.

description: Self-adjoint Schrödinger operators with $δ$ and $δ'$-potentials supported on a smooth compact hypersurface are defined explicitly via boundary conditions. The spectral properties of these operators are investigated, regularity results on the functions in their domains are obtained, and analogues of the Birman--Schwinger principle and a variant of Krein's formula are shown. Furthermore, Schatten--von Neumann type estimates for the differences of the powers of the resolvents of the Schrödinger operators with $δ$ and $δ'$-potentials, and the Schrödinger operator without a singular interaction are proved. An immediate consequence of these estimates is the existence and completeness of the wave operators of the corresponding scattering systems, as well as the unitary equivalence of the absolutely continuous parts of the singularly perturbed and unperturbed Schrödinger operators. In the proofs of our main theorems we make use of abstract methods from extension theory of symmetric operators, some algebraic considerations and results on elliptic regularity.

description: The dimer-atom-atom recombination process in the system of four identical bosons with resonant interactions is studied. The description uses the exact Alt, Grassberger and Sandhas equations for the four-particle transition operators that are solved in the momentum-space framework. The dimer-dimer and atom-trimer channel contributions to the ultracold dimer-atom-atom recombination rate are calculated. The dimer-atom-atom recombination rate greatly exceeds the three-atom recombination rate.

description: Employing Monte-Carlo simulation techniques we investigate the statistical properties of equally charged particles confined in a one-dimensional box trap and detect a crossover from a crystalline to a cluster phase with increasing temperature. The corresponding transition temperature depends separately on the number of particles N and the box size L, implying non-extensivity due to the long-range character of the interactions. The probability density of the spacing between the particles exhibits at low temperatures an accumulation of discrete peaks with an overall asymmetric shape. In the vicinity of the transition temperature it is of a Gaussian form whereas in the high temperature regime an exponential decay is observed. The high temperature behaviour shows a cluster phase with a mean cluster size that first increases with the temperature and then saturates. The crossover is clearly identifiable also in the non-linear behaviour of the heat capacity with varying temperature. The influence of the trapping potential on the observed results as well as possible experimental realizations are briefly addressed.

Subjects: subject: Computer science.

description: In this thesis, the approaches to achieving real time control under Linux operating platform are presented and four different real time control applications are discussed. The driver of the ADS 12 data acquisition card is programmed to enhance hardware supported by COMEDI through which the connection between computer and DAQ boards are built up. A simple project combining RTAI (Real Time Application Interface) with COMEDI is introduced together with the discussion of one SISO (Single-Input Single-Output) control project and two SIMO (Single-Inputs Multi- Output) control projects based on different controllers, and RTLab is selected to provide us with real time functionalities as it combines COMEDI with RTAI or RTLinx very well in Linux. Further more, to enhance the observability and maneuverability of RTLab, additional custom plugin graphic windows have also been made for every application in the project.

description: We measure the in-plane distribution of thermally activated vortices in a trapped quasi-2D Bose gas, where we enhance the visibility of density-depleted vortex cores by radially compressing the sample before releasing the trap. The pairing of vortices is revealed by the two-vortex spatial correlation function obtained from the vortex distribution. The vortex density decreases gradually as temperature is lowered, and below a certain temperature, a vortex-free region emerges in the center of the sample. This shows the crossover from a Berezinskii-Kosterlitz-Thouless phase containing vortex-pair excitations to a vortex-free Bose-Einstein condensate in a finite-size 2D system.

description: Krebs ist weltweit die häufigste Todesursache, und trotz der in den letzten Jahrzehnten erzielten Therapieverbesserungen sind Tumorrezidive und Metastasen nach wie vor das größte Problem für den Therapieerfolg. Tumore zeichnen sich durch eine heterogene Zellpopulation aus, die auf die sich rasch entwickelnde dynamische Mikroumgebung des Tumors zurückzuführen ist. Die Blutgefäße, die sich während der Tumorbildung bilden, weisen eine desorganisierte Struktur auf, die zur Entwicklung einer hypoxischen Umgebung im Tumor beiträgt. Eine solche Mikroumgebung führt zur Entwicklung einer Subpopulation von Tumorzellen, die einen mesenchymalen Phänotyp aufweisen und in das Blut und die Lymphgefäße einwandern können. Bei diesen Zellen handelt es sich um die zirkulierenden Krebsstammzellen (CCSCs), die strahlenresistent sind und folglich für die Metastasenbildung verantwortlich sind. CCSCs verfügen über Marker, die für die Migration und Stammzelleneigenschaft (CD133), die Resistenz gegen Anoikis (Trk B), den programmierten Zelltod, und die Immunabwehr (CD47) entscheidend sind. Die Hypoxie trägt dazu bei, die Stammzellenkapazität zu simulieren und die Subpopulation der CD133-positiven Zellen zu selektieren. Darüber hinaus sind diese Zellen strahlenresistent und eine weitere Selektion ist möglich, nachdem sie ionisierender Strahlung ausgesetzt wurden. Idealerweise würde ihre Isolierung, Kultivierung und Charakterisierung in vitro die Möglichkeit bieten, das Wissen über die für die Metastasenbildung verantwortlichen Mechanismen zu erweitern. Es ist jedoch technisch äußerst anspruchsvoll, sie im Blutkreislauf zu identifizieren, da sie nur in geringer Zahl im Blutkreislauf vorhanden sind. Zu diesem Zweck haben wir in dieser In-vitro-Studie unter Verwendung von Hypoxie (akut und chronisch) und ionisierender Strahlung (4 Gy Röntgenstrahlung) Zellen mit einem CCSC-ähnlichen Phänotyp für die weitere Charakterisierung ausgewählt. Wir haben versucht, diese Zellen ex vivo aus dem Blut der Tiere zu isolieren und zu charakterisieren. Dabei untersuchten wir die Expression der CD133- und CD47-Marker zwischen Primärtumor und Metastasen durch histologische Analyse von Proben, die im In-vivo-Mausexperiment gewonnen wurden.

description: Despite more than a decade of research on adiabatic quantum computation (AQC), its decoherence properties are still poorly understood. Many theoretical works have suggested that AQC is more robust against decoherence, but a quantitative relation between its performance and the qubits' coherence properties, such as decoherence time, is still lacking. While the thermal excitations are known to be important sources of errors, they are predominantly dependent on temperature but rather insensitive to the qubits' coherence. Less understood is the role of virtual excitations, which can also reduce the ground state probability even at zero temperature. Here, we introduce normalized ground state fidelity as a measure of the decoherence-induced deformation of the ground state due to virtual transitions. We calculate the normalized fidelity perturbatively at finite temperatures and discuss its relation to the qubits' relaxation and dephasing times, as well as its projected scaling properties.

On the possibility of neutrino flavor identification at the highest energies

description: High energy astrophysical neutrinos carry relevant information about the origin and propagation of cosmic rays. They can be created as a by-product of the interactions of cosmic rays in the sources and during propagation of these high energy particles through the intergalactic medium. The determination of flavor composition in this high energy flux is important because it presents a unique chance to probe our understanding of neutrino flavor oscillations at gamma factors >10^21. In this work we develop a new statistical technique to study the flavor composition of the incident neutrino flux, which is based on the multipeak structure of the longitudinal profiles of very deep electron and tau neutrino horizontal air showers. Although these longitudinal profiles can be observed by means of fluorescence telescopes placed over the Earth's surface, orbital detectors are more suitable for neutrino observations owing to their much larger aperture. Therefore, we focus on the high energy region of the neutrino spectrum relevant for observations with orbital detectors like the planned JEM-EUSO telescope.

Three-body couplings in RMF and its effects on hyperonic star equation of state

description: We develop a new relativistic mean field (RMF) model including explicit three-body couplings and apply it to hyperonic systems and neutron star matter. The recent observation of the massive mass neutron star has given us a puzzle; when strange hadrons including hyperons are taken into account, the equation of state (EOS) becomes too soft to support the observed two-solar-mass neutron star. Three-baryon repulsion is a promising ingredient to answer this puzzle. We demonstrate that it is possible to consistently explain the massive neutron star and hypernuclear data when we include three-body couplings and modify the hyperon vector couplings from the flavor SU(3) values.

description: The spin and layer (pseudospin) degrees of freedom are entangled coherently in the canted antiferromagnetic phase of the bilayer quantum Hall system at the filling factor $ν=2$. There emerges a complex Goldstone mode describing such a combined degree of freedom. In the zero tunneling-interaction limit ($Δ_{\text{SAS}}\rightarrow 0$), its phase field provokes a supercurrent carrying both spin and charge within each layer. The Hall resistance is predicted to become anomalous precisely as in the $ν=1$ bilayer system in the counterflow and drag experiments. Furthermore, it is shown that the total current flowing in the bilayer system is a supercurrent carrying solely spins in the counterflow geometry. It is intriguing that all these phenomena occur only in imbalanced bilayer systems.

description: The Dicke model of cavity quantum electrodynamics is approximately realized in condensed matter when the cyclotron transition of a two-dimensional electron gas is nearly resonant with a cavity photon mode. We point out that in the strong coupling limit the Dicke model of cavity cyclotron resonance must be supplemented by a term that is quadratic in the cavity photon field and suppresses the model's transition to a super-radiant state. We develop the theory of graphene cavity cyclotron resonance and show that the quadratic term, which is absent in graphene's low-energy Dirac model Hamiltonian, is in this case dynamically generated by virtual inter-band transitions.

description: We investigate the effect of electron beam irradiation on the dielectric properties of As2S3 Chalcogenide glass. By means of low-loss Electron Energy Loss Spectroscopy, we derive the permittivity function, its dispersive relation, and calculate the refractive index and absorption coefficients under the constant permeability approximation. The measured and calculated results show, to the best of our knowledge, a heretofore unseen phenomenon: the reduction in the permittivity of <40%, and consequently a modification of the refractive index follows, reducing it by 20%, hence suggesting a significant change on the optical properties of the material. The plausible physical phenomena leading to these observations are discussed in terms of the homopolar and heteropolar bond dynamics under high energy absorption.

description: We present the first complete 55-671 um spectral scan of a low-mass Class 0 protostar (Serpens SMM1) taken with the PACS and SPIRE spectrometers on board Herschel. More than 145 lines have been detected, most of them rotationally excited lines of 12CO (full ladder from J=4-3 to 42-41), H2O, OH, 13CO, HCN and HCO+ . Bright [OI]63,145um and weaker [CII]158 and [CI]370,609um lines are also detected. Mid-IR spectra retrieved from the Spitzer archive are also first discussed here, they show clear detections of [NeII], [FeII], [SiII] and [SI] fine structure lines as well as weaker H2 S(1) and S(2) pure rotational lines. The observed line luminosity is dominated by CO (~54%), H2O (~22%), [OI] (~12%) and OH (~9%) emission. A non-LTE radiative transfer model allowed us to quantify the contribution of the 3 different temperature components suggested by the 12CO rotational ladder (Tk(hot)~800 K, Tk(warm)~375 K and Tk(cool)~150 K). Gas densities n(H2)~5x10^6 cm^-3 are needed to reproduce the observed far-IR lines arising from shocks in the inner protostellar envelope for which we derive upper limit abundances of x(CO)~10^-4, x(H2O)~0.2x10^-5 and x(OH)~10^-6. The lower energy submm 12CO and H2O lines show more extended emission that we associate with the cool entrained outflow gas. Fast dissociative J-shocks (v_s > 60 km s^-1) as well as lower velocity non-dissociative shocks (v_s < 20 km s^-1) are needed to explain both the atomic lines and the hot CO and H2O lines respectively. Observations also show the signature of UV radiation and thus, most observed species likely arise in UV-irradiated shocks. Dissociative J-shocks produced by an atomic jet are the most probable origin of [OI] and OH emission and of a significant fraction of the warm CO emission. In addition, H2O photodissociation in UV-irradiated non-dissociative shocks can also contribute to the [OI] and OH emission.

This implies that all zeta-correlators are time independent at all orders in the loop expansion. Our result follows directly from locality and diffeomorphism invariance of the underlying theory. We also explore the relationship between the conservation of zeta, the single-field consistency relation and the renormalization of composite operators.

title: Between success and dislocation: the experience of long-range upward mobility in contemporary Chile

description: This doctoral dissertation examines the experience of long-range upward mobility in contemporary Chile. Internationally well-known for the implementation of pioneering and radical neoliberal reforms, Chile has both high rates of occupational mobility and a strong trend towards social closure at the top. Based on an extensive qualitative study, this research focuses on those who best represent the embodiment of the meritocratic ideal across Western nations: the long-range upwardly mobile coming from disadvantaged backgrounds and reaching high-status occupations after attending elite universities. Endorsing an increasing sociological interest in the study of the elites, this thesis argues for the need to move from the conventional occupational-based approach towards a cultural and multigenerational perspective on social mobility. In particular, it acknowledges the crucial significance of concepts such as cultural capital and cultural repertoires used in tandem with three different sources of multigenerational transmission underpinning upward mobility: families, schools, and high-status occupations. The findings reveal a double-faced experience associated with a long-range upward trajectory in the Chilean context: while one of these faces indicates the lingering class dislocation the long-range upwardly mobile experience regarding both their ties of origin and destination, the other side emphasises the constant search to re-find belonging and meaning to their displaced sense of self in the social space. The variability fashioning this double-faced experience is largely dependent on a number of intervening or mediating factors underpinning their upward trajectories: geographical origin, the cultural repertoires tied to their backgrounds of origin, gender, school trajectory, and the specific occupational settings sustaining their professional lives. Drawing on these findings, this doctoral dissertation contributes to reorient research on mobility, both in the Global South and North, by promoting greater cross-fertilisation between the contributions emerging from cultural sociology with a broad multi-generational view of inequality.

description: The robustness of the topological color code, which is a class of error correcting quantum codes, is investigated under the influence of an uniform magnetic field on the honeycomb lattice. Our study relies on two high-order series expansions using perturbative continuous unitary transformations in the limit of low and high fields, exact diagonalization and a classical approximation. We show that the topological color code in a single parallel field is isospectral to the Baxter-Wu model in a transverse field on the triangular lattice. It is found that the topological phase is stable up to a critical field beyond which it breaks down to the polarized phase by a first-order phase transition. The results also suggest that the topological color code is more robust than the toric code, in the parallel magnetic field.

description: Diese Dissertation besteht aus drei unabhängigen Kapiteln auf dem Gebiet der Mechanismus-Design-Theorie, mit einem besonderen Schwerpunkt auf ausschließbaren öffentlichen Gütern und dynamischem Mechanismus-Design. Die ersten beiden Kapitel befassen sich mit optimalen Preismechanismen für den Verkauf von ausschließbaren öffentlichen Gütern. Das erste Kapitel untersucht diese Thematik in einer sequenziellen Screening-Umgebung, während das zweite Kapitel den Einfluss von Netzwerk-Externalitäten auf optimale Preisfindungsstrategien für diese Güter analysiert. Das letzte Kapite untersucht die Auswirkungen von "Big Data" im dynamischen Mechanismusdesign und konzentriert sich dabei auf eine Ein-Käufer-Ein-Verkäufer Situation. Dieses Kapitel vergleicht die Auszahlungen der beteiligten Agenten in diesem Kontext und liefert Einblicke durch theoretische Analysen und die Nutzung von Simulationen.
description: This dissertation comprises three independent yet interconnected chapters in the field of mechanism design, with a specific focus on excludable public goods and dynamic mechanism design. The first two chapters study optimal pricing mechanisms for selling excludable public goods. Chapter 1 explores this issue in a sequential screening environment. Chapter 2 examines the impact of network effects on optimal pricing strategies for these goods. Chapter 3 studies the impact of "big data" in dynamic mechanism design, focusing on a one-buyer-one-seller setting. This chapter compares the payoffs of involved agents in this context, providing insights through theoretical analysis and the use of simulations.
title: The effects of changes in climate and food supply on the timing of reproduction in Great Skuas (Stercorarius skua) and Arctic Skuas (Stercorarius parasiticus)

description: This paper will examine the relationship between marine predators and disruptions of the Shetland and North Sea fishery due to anthropogenic climate change. The frrst chapter will give an overview of localized climate patterns in Shetland and the wider ocean areas, with some original analysis of raw climate data from the region. Climate models specific area will be used to determine if statistically significant trends in ocean temperature exist in the southern North Sea outside of the normal cyclic climate patterns known as the North Atlantic Oscillation and the Arctic Oscillation. Winter sea surface temperature will be used throughout as a proxy for climate variation, as this is more stable an indicator than air temperature, and more relevant to the life cycles of pelagic organisms. Confrrming the presence of climate change in the study area is necessary to posit a causal link between climate change and alterations in the region's ecosystem. The Shetland plankton community is the topic of the second chapter, with statistical analysis of relationships between plankton types and climate change, as well as interactions within the plankton community. The frrst focus of the chapter is to determine if a significant relationship exists between variation in climate and the life cycle of phytoplankton, specifically diatoms, which are the most abundant species. The second is to determine the nature of the relationship, if any, between diatom life cycle and productivity and the success of zooplankton-specifically copepods, Chapter Three examines the relationship between sandeels and copepods, which are their preferred food species. Both copepod population and the timing of the population peak are considered as possible drivers of sandeel population success. Furthermore, the possibility of a direct link between sea surface temperature and sandeel numbers is explored using regression analysis. 7 Finally, we examine the relationship between seabird phenology, sandeel biomass by using the Great and Arctic Skuas nesting on Foula as study populations. Regression analysis will be used to study the significant relationship, if any, between sandeel population on skua breeding success and the timing of nesting. The implications of these relationships will then be discussed on an ecosystem scale. This will allow the creation of an overall model of the southern North Sea ecosystem's response to anthropogenic climate change by modeling the mechanisms at each level of the food web.

description: We demonstrate the existence of a novel set of discrete symmetries in the context of N = 2 supersymmetric (SUSY) quantum mechanical model with a potential function f(x) that is a generalization of the potential of the 1D SUSY harmonic oscillator. We perform the same exercise for the motion of a charged particle in the X-Y plane under the influence of a magnetic field in the Z-direction. We derive the underlying algebra of the existing continuous symmetry transformations (and corresponding conserved charges) and establish its relevance to the algebraic structures of the de Rham cohomological operators of differential geometry. We show that the discrete symmetry transformations of our present general theories correspond to the Hodge duality operation. Ultimately, we conjecture that any arbitrary N = 2 SUSY quantum mechanical system can be shown to be a tractable model for the Hodge theory.

description: We study the geometric properties of the manifold of states described as (uniform) matrix product states. Due to the parameter redundancy in the matrix product state representation, matrix product states have the mathematical structure of a (principal) fiber bundle. The total space or bundle space corresponds to the parameter space, i.e. the space of tensors associated to every physical site. The base manifold is embedded in Hilbert space and can be given the structure of a Kähler manifold by inducing the Hilbert space metric. Our main interest is in the states living in the tangent space to the base manifold, which have recently been shown to be interesting in relation to time dependence and elementary excitations. By lifting these tangent vectors to the (tangent space) of the bundle space using a well-chosen prescription (a principal bundle connection), we can define and efficiently compute an inverse metric, and introduce differential geometric concepts such as parallel transport (related to the Levi-Civita connection) and the Riemann curvature tensor.

Reanalysis of nuclear spin matrix elements for dark matter spin-dependent scattering

description: We show how to include in the existing calculations for nuclei other than $^{129}$Xe, $^{131}$Xe, the corrections to the isovector coupling arising in chiral effective field theory recently found in Ref. \cite{Menendez1}. The dominant, momentum independent, 2-body currents effect can be taken into account by formally redefining the static spin matrix elements $< \mathbf{S}_{p,n} >$. By further using the normalized form factor at $q\neq 0$ built with the 1-body level structure functions, we show that the WIMP-nucleus cross section and the upper limits on the WIMP-nucleon cross sections coincide with the ones derived using the exact functions at the 2-body level. We explicitly show it in the case of XENON100 limits on the WIMP-neutron cross section and we recalculate the limits on the WIMP-proton spin dependent cross section set by COUPP. We also give practical formulas to obtain $< \mathbf{S}_{p,n} >$ given the structure functions in the various formalisms/notations existing in literature. We argue that the standard treatment of the spin-dependent cross section in terms of three independent isospin functions, $S_{00}(q)$, $S_{11}(q)$, $S_{01}(q)$, is redundant in the sense that the interference function $S_{01}(q)$ is the double product $|S_{01}(q)|=2\sqrt{S_{00}(q)}\sqrt{S_{11}(q)}$ even when including the new effective field theory corrections.
