description: We investigate the effect of the laser parameters of pulsed laser deposition on the film stoichiometry and electronic properties of LaAlO_3/SrTiO_3 (001) heterostructures. The La/Al ratio in the LaAlO_3 films was varied over a wide range from 0.88 to 1.15, and was found to have a strong effect on the interface conductivity. In particular, the carrier density is modulated over more than two orders of magnitude. The film lattice expansion, caused by cation vacancies, is found to be the important functional parameter. These results can be understood to arise from the variations in the electrostatic boundary conditions, and their resolution, with stoichiometry.

title: Weiblicher Phallizismus' im deutschen Hip Hop: SXTNs FTZN IM CLB zwischen weiblicher Selbstermächtigung und Rekonstitution des Patriarchats
Creators: name: Riggert, Mirja
Publisher: name: Göttinger Centrum für Geschlechterforschung
Year: 2019

description: Das Berliner Hip Hop-Duo SXTN ist vor allem wegen seiner provokanten Texte bekannt, die der männlich geprägten Rhetorik des Battle- und Gangsta-Rap entlehnt sind. Der vorliegende Beitrag analysiert ihr 2016 veröffentlichtes Musikvideo FTZN IM CLB hinsichtlich des emanzipatorischen Potentials, das den beiden Rapperinnen in der medialen Betrachtung vielfach attestiert wird. In einer konfigurativen Bild-Text-Ton-Analyse werden gendertheoretische Annahmen auf das Musikstück bezogen. Es wird gezeigt, dass über die Inszenierung aggressiver Schwesternschaft in FTZN IM CLB phallogozentrische Weiblichkeitsbilder dekonstruiert werden, indem feminine Topoi mit männlich konnotierten Verhaltensweisen verflochten werden. Zugleich zeigt sich aber auch, dass über die mimetische Adaption eines männlichen Habitus ein derivativer Status der weiblichen Position re-zementiert wird. Dafür ist besonders das von Angela McRobbie eingeführte Konzept des ‚weiblichen Phallizismus‘ (2009) bedeutsam, das in der phallischen Frau eine Re-Stabilisierung der Geschlechterhierarchie sieht. In SXTNs Rhetorik der Selbstbehauptung wird deutlich, wie sich dieses Konzept unter dem Deckmantel einer weiblichen Ermächtigung manifestiert.
description: The Berlin Hip Hop duo SXTN is famous for its provocative lyrics borrowed from the male-dominated rhetoric of battle and gangsta rap. The present article analyses the music video FTZN IM CLB of 2016 regarding its emancipatory potential, which the media frequently attributes to the female rappers. A configurative analysis of visual, textual and tonal elements applies assumptions of gender theory to the video. Thus, it becomes obvious that performing an aggressive sisterhood in FTZN IM CLB results in deconstructing phallogocentric images of femininity because feminine topoi are intertwined with male connoted behavior. At the same time, the mimetic adaptation of a male habit reinforces the female position as a derivative of the male. This is conceptualized in the idea of “female phallicism” by Angela McRobbie (2009), which considers the “phallic girl” a restabilization of gender hierarchy. In the self-assertive rhetoric of SXTN it becomes evident how this concept manifests itself under the guise of female empowerment.

description: Seit den 1970ern ist geschlechtergerechte Sprache (ggS) im deutschen Sprachraum ein Thema. Die Diskussionen wandelten sich dabei stark. Ging es erst vorrangig um Sichtbarkeit von Frauen, stehen seit den 1990ern Heteronormativitätskritik und die Suche nach inklusiven Sprachformen im Vordergrund. Die vertretenen Positionen haben sich nicht abgelöst, sondern ergänzen sich teilweise oder stehen nebeneinander (in Konflikt). Trotz einer gewissen Institutionalisierung hat ggS ins wissenschaftliche Register kaum Aufnahme gefunden. Dabei ist Sprachwandel besonders wirksam, wenn statushohe Gruppen ihn vorleben. Zudem ist ggS exakter als ‚generische‘ Maskulina. Über ihren Gebrauch von ggS sowie ihre Präferenz bestimmter Formen, bzw. Hinderungsgründe für deren Verwendung, wurden in einer Online-Erhebung 290 Wissenschaftler_innen aus Geschlechterforschung und Medizin befragt. Die Ergebnisse wurden deskriptiv ausgewertet und dann hinsichtlich geschlechtertheoretischer Überlegungen reflektiert.

description: In the 1970s, gender-fair language became a much debated topic in Germany. Since then, the motiva-tion for its use, as well as the linguistic forms used to promote it, have changed considerably. Initially, visibility of women was pursued. Since the 1990s, a critique of heteronormativity emerged, and a ten-dency towards more inclusive linguistic forms grew. To this day, gender-fair language is noticeably absent in most academic texts. This is surprising, as gender-fair language is more precise than the use of generic masculine forms. Also, the language use by high-status groups, such as academics, tends to function as a role model. To explore this issue, 290 academics from the areas of gender studies and medicine were consulted in an online survey about their use of gender-fair language, their preferences for certain options, and possible impediments. After a descriptive analysis of the findings, they were discussed in a gender-theoretical context and used for an outlook into future developments.

Incommensurability Effects in Odd Length J_1-J_2 Quantum Spin Chains: On-site magnetization and Entanglement

description: For the antiferromagnetic J_1-J_2 quantum spin chain with an even number of sites, the point J_2^d=1/2 J_1 is a disorder point. It marks the onset of incommensurate real space correlations for J_2>J_2^d. At a distinct larger value of J_2^L=0.52036(6)J_1, the Lifshitz point, the peak in the static structure factor begins to move away from k=π. Here, we focus on chains with an odd number of sites. In this case the disorder point is also at J_2^d=1/2 J_1, but the behavior close to the Lifshitz point, J_2^L approx. 0.538 J_1, is quite different: starting at J_2^L, the ground-state goes through a sequence of level crossings as its momentum changes away from k=π/2. An even length chain, on the other hand, is gapped for any J_2>0.24J_1 and has the ground-state momentum k=0. This gradual change in the ground-state wave function for chains with an odd number of sites is reflected in a dramatic manner directly in the ground-state on-site magnetization as well as in the bi-partite von Neumann entanglement entropy. Our results are based on DMRG calculations and variational calculations performed in a restricted Hilbert space defined in the valence bond picture. In the vicinity of the point J_2=1/2 J_1, we expect the variational results to be very precise.

description: Over the past few years, we developed a mathematically rigorous method to study the dynamical processes associated to nonlinear Forchheimer flows for slightly compressible fluids. We have proved the existence of a geometric transformation which relates constant mean curvature surfaces and time-invariant pressure distribution graphs constrained by the Darcy-Forchheimer law. We therein established a direct relationship between the CMC graph equation and a certain family of equations which we call $g$-Forchheimer equations. The corresponding results, on fast flows and their geometric interpretation, can be used as analytical tools in evaluating important technological parameters in reservoir engineering.

description: We study the decoherence and thermalization dynamics of a nanoscale system coupled nonperturbatively to a fully quantum-mechanical bath. The system is prepared out of equilibrium in a pure state of the complete system. We propose a random matrix model and show analytically that there are two robust temporal regimes in the approach of the system to equilibrium --- an initial Gaussian decay followed by an exponential tail, consistent with numerical results on small interacting lattices [S. Genway, A.F. Ho and D.K.K. Lee, Phys. Rev. Lett. 105, 260402 (2010)]. Furthermore, the system decays towards a Gibbs ensemble in accordance with the eigenstate thermalization hypothesis.

A Systematic Study on Matrix Models for Chern-Simons-matter Theories
Creators: name: Suyama, Takao

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate the planar solution of matrix models derived from various Chern-Simons-matter theories compatible with the planar limit. The saddle-point equations for most of such theories can be solved in a systematic way. A relation to Fuchsian systems play an important role in obtaining the planar resolvents. For those theories, the eigenvalue distribution is found to be confined in a bounded region even when the 't Hooft couplings become large. As a result, the vevs of Wilson loops are bounded in the large 't Hooft coupling limit. This implies that many of Chern-Simons-matter theories have quite different properties from ABJM theory. If the gauge group is of the form ${\rm U}(N_1)_{k_1}\times{\rm U}(N_2)_{k_2}$, then the resolvents can be obtained in a more explicit form than in the general cases.

In this work we are going to present an environment for the integration of knowledge expressed in such a way. Guaranteeing knowledge integration is an important element during the development of the Semantic Web. Thanks to this, it is possible to obtain access to services which offer knowledge contained in various distributed databases associated with semantically described web portals. We will present the advantages of the multi-agent approach while solving this problem. Then, we will describe an example of its application in systems supporting company management knowledge in the process of constructing supply-chains.

description: We explore the possibility of light and superlight sterile neutrinos in the recently proposed Minimal Radiative Inverse Seesaw extension of the Standard Model for neutrino masses, in which all existing neutrino data can be explained. In particular, we discuss two benchmark scenarios with one of the three sterile neutrino states in the keV-range, having very small mixing with the active neutrinos to account for the Dark Matter in the Universe, while (i) the other two light sterile neutrino states could be in the eV-range, possessing a nonzero mixing with the active states as required to explain the LSND+MiniBooNE+reactor neutrino data, or (ii) one of the light sterile states is in the eV-range, whereas the second one could be superlight and almost mass-degenerate with the solar neutrinos. Such superlight sterile neutrinos could give rise to potentially observable effects in future neutrino oscillation experiments and may also offer a possible explanation for the extra radiation observed in the Universe.

description: Random walks in random sceneries (RWRS) are simple examples of stochastic processes in disordered media. They were introduced at the end of the 70's by Kesten-Spitzer and Borodin, motivated by the construction of new self-similar processes with stationary increments. Two sources of randomness enter in their definition: a random field $ξ= (ξ_x)_{x \in \Z^d}$ of i.i.d.\ random variables, which is called the \emph{random scenery}, and a random walk $S = (S_n)_{n \in \N}$ evolving in $\Z^d$, independent from the scenery. The RWRS $Z = (Z_n)_{n \in \N}$ is then defined as the accumulated scenery along the trajectory of the random walk, i.e., $Z_n := \sum_{k=1}^n ξ_{S_k}$. The law of $Z$ under the joint law of $ξ$ and $S$ is called "annealed", and the conditional law given $ξ$ is called "quenched". Recently, central limit theorems under the quenched law were proved for $Z$ by the first two authors for a class of transient random walks including walks with finite variance in dimension $d \ge 3$. In this paper we extend their results to dimension $d=2$.

description: Spin qubits have been successfully realized in electrostatically defined, lateral few-electron quantum dot circuits. Qubit readout typically involves spin to charge information conversion, followed by a charge measurement made using a nearby biased quantum point contact. It is critical to understand the back-action disturbances resulting from such a measurement approach. Previous studies have indicated that quantum point contact detectors emit phonons which are then absorbed by nearby qubits. We report here the observation of a pronounced back-action effect in multiple dot circuits where the absorption of detector-generated phonons is strongly modified by a quantum interference effect, and show that the phenomenon is well described by a theory incorporating both the quantum point contact and coherent phonon absorption. Our combined experimental and theoretical results suggest strategies to suppress back-action during the qubit readout procedure.

The light techni-dilaton then mixes with the composite Higgs, which is predicted to be narrow and light in walking technicolor models. It is an interesting possibility that the newly discovered boson at LHC might be a mixed state of techni-dilaton and the composite Higgs.

description: The main signalling proteins that control early kidney branching have been defined. Yet the underlying mechanism is still elusive. We have previously shown that a Schnakenberg-type Turing mechanism can recapitulate the branching and protein expression patterns in wildtype and mutant lungs, but it is unclear whether this mechanism would extend to other branched organs that are regulated by other proteins. Here we show that the GDNF-RET regulatory interaction gives rise to a Schnakenberg-type Turing model that reproduces the observed budding of the ureteric bud from the Wolffian duct, its invasion into the mesenchyme, and the observed branching pattern. The model also recapitulates all relevant protein expression patterns in wild-type and mutant mice. The lung and kidney models are both based on a particular receptor- ligand interaction and require: (1) cooperative binding of ligand and receptor, (2) a lower diffusion coefficient for the receptor than for the ligand, and (3) an increase in the receptor concentration in response to receptor-ligand binding (by enhanced transcription, more recycling or similar). These conditions are met also by other receptor-ligand systems. We propose that ligand-receptor based Turing patterns represent a general mechanism to control branching morphogenesis and other developmental processes.
Mechanism for the suppression of quantum noise at large scales on expanding space

description: We present an exactly-solvable model for the suppression of quantum noise at large scales on expanding space. The suppression arises naturally in the de Broglie-Bohm pilot-wave formulation of quantum theory, according to which the Born probability rule has a dynamical origin. For a scalar field on a radiation-dominated background we construct the exact solution for the time-evolving wave functional and study properties of the associated field trajectories. It is shown that the time evolution of a field mode on expanding space is mathematically equivalent to that of a standard harmonic oscillator with a 'retarded time' that depends on the wavelength of the mode. In the far super-Hubble regime the equivalent oscillator evolves over only one Hubble time, yielding a simple mechanism whereby relaxation to the Born rule can be suppressed on very large scales. We present numerical simulations illustrating how the expansion of space can cause a retardation of relaxation in the super-Hubble regime. Given these results it is natural to expect a suppression of quantum noise at super-Hubble wavelengths. Such suppression could have taken place in a pre-inflationary era, resulting in a large-scale power deficit in the cosmic microwave background.

description: The isotropy and homogeneity of the cosmic microwave background (CMB) favors "scalar driven" early Universe inflationary models. Non-scalar fields, and in particular gauge fields, are on the other hand commonplace in all high energy particle physics models proposed to be at work at the upper bound on energy scale of inflation set by the current CMB observations. In this review we consider the role and consequences, theoretical and observational, that gauge fields can have during inflationary era. Gauge fields may be turned on in the background during inflation, or may become relevant at the level of cosmic perturbations. There have been two main class of models with gauge fields in the background, models which show violation of cosmic no-hair theorem and those which lead to isotropic FLRW cosmology, respecting the cosmic no-hair theorem. Models in which gauge fields are only turned on at the cosmic perturbation level, may source primordial magnetic fields. We also review specific observational features of these models on the CMB and/or the primordial cosmic magnetic fields. Our discussions will be mainly focused on the inflation period, with only a brief discussion on the post inflationary (p)reheating era.

description: The ratios of fluxes of heavy nuclei from sulfur (Z=16) to chromium (Z=24) to the flux of iron were measured by the ATIC-2 experiment. The ratios are decreasing functions of energy from 5 GeV/n to approximately 80 GeV/n, as expected. However, an unexpected sharp upturn in the ratios are observed for energies above 100 GeV/n for all elements from Z=16 to Z=24. Similar upturn but with lower amplitude was also discovered in the ATIC-2 data for the ratio of fluxes of abundant even nuclei (C, O, Ne, Mg, Si) to the flux of iron. Therefore the spectrum of iron is significantly different from the spectra of other abundant even nuclei.

description: The suppression of heavy quarkonia e.g. $J/ψ$, $Υ$ etc. is considered as a suitable probe to identify the nature of the matter created in heavy ion collisions. Recently we have presented a modified colour screening model for $J/ψ$ suppression in the quark gluon plasma (QGP) using quasiparticle model as the equation of state. In this paper, we extend our model to calculate the anomalous suppression of various states of $Υ$ arising due to QGP medium alone. We obtain the suppression patterns of different bottomonia states with respect to centrality at various available collision energies and compare them with the available experimental data.

description: Der pädagogische Alltag in Krippen wird durch die Altersmischung der Gruppen geprägt. Fachkräfte betreuen in diesen Gruppen sowohl Säuglinge als auch mobile, sich verbal ausdrückende Kleinkinder, welche verschiedene alters- und entwicklungsspezifische Anforderungen mitbringen. Unklar ist, wie Fachkräfte diese Herausforderung wahrnehmen und dazu eingestellt sind. Der Artikel fokussiert daher Einstellungen zur Altersmischung und analysiert diese mittels Befragungsdaten von 65 Fachkräften in Krippen. Es zeigt sich, dass Fachkräfte sowohl die Herausforderung der Altersmischung wahrnehmen, als auch in dieser Chancen für die soziale Entwicklung der Kinder sehen.

description: The pedagogical everyday life in daycare centers is shaped by the age-mix in the groups. Educators in these groups care for children from the age of infants up to toddlers and children who express themselves verbally and who have different age- and development-specific needs. It is unclear how educators perceive this challenge and what their attitude is towards an age-mix. Therefore, this article focuses on the age-mix and analyses it by using data from 65 educators in daycare centers. Results demonstrate that educators perceive the age-mix both as a challenge and as a chance for the social development of the children.

description: Electron transfer (ET) between primary electron donors and acceptors is modeled in the photosystem II reaction center (RC). Our model includes (i) two discrete energy levels associated with donor and acceptor, interacting through a dipole-type matrix element and (ii) two continuum manifolds of electron energy levels ("sinks"), which interact directly with the donor and acceptor. Namely, two discrete energy levels of the donor and acceptor are embedded in their independent sinks through the corresponding interaction matrix elements. We also introduce classical (external) noise which acts simultaneously on the donor and acceptor (collective interaction). We derive a closed system of integro-differential equations which describes the non-Markovian quantum dynamics of the ET. A region of parameters is found in which the ET dynamics can be simplified, and described by coupled ordinary differential equations. Using these simplified equations, both sharp and flat redox potentials are analyzed. We analytically and numerically obtain the characteristic parameters that optimize the ET rates and efficiency in this system.

description: An extensive search for low-energy lithium defects in crystalline silicon using density-functional-theory methods and the ab initio random structure searching (AIRSS) method shows that the four-lithium-atom substitutional point defect is exceptionally stable. This defect consists of four lithium atoms with strong ionic bonds to the four under-coordinated atoms of a silicon vacancy defect, similar to the bonding of metal ions in Zintl phases. This complex is stable over a range of silicon environments, indicating that it may aid amorphization of crystalline silicon and form upon delithiation of the silicon anode of a Li-ion rechargeable battery.

description: Digitale Medien sind im Alltag von Kleinkindern im privaten Bereich fest verankert. Anders sieht es jedoch im Kindergarten selbst aus. Die hier vorliegenden Ergebnisse aus Interviews mit Kindergartenpädagoginnen und -pädagogen zeigen, welche Potentiale und Gefahren gesehen werden und wie mit digitaler Medienbildung in der Praxis umgegangen wird. Dabei wird erkennbar, dass
Medienkompetenz zwar als wichtig erachtet wird, die Verantwortung für den Erwerb von Medienkompetenz jedoch an die Familie delegiert wird.

This paper presents results from interviews with kindergarten teachers and shows which potentials and dangers are seen by them as well as their understanding of digital media literacy. Results show that they recognize that media literacy is essential, however it is not seen as important part of kindergarten education.

description: This work represents an application of constant mean curvature graphs (as solutions of the mean curvature PDE) to non-linear non-Darcy flows in porous media. It relates time invariant pressure distribution graphs to graphs of constant mean curvature surfaces. This differential geometric interpretation provides an important tool for evaluating technological parameters in reservoir engineering.

Противоречия между государством и политикой православия обуславливались различиями в принципах, поскольку правительство руководствовалось интересами Рос¬сии на востоке империи, а православная церковь видела свою задачу в подавлении влияния буддийского духовенства посредством достижения религиозно-мировоззренческой гомогенности бурят с русским населением.

description: We generalize the exact field theoretic correspondence proposed in arXiv:1103.5726 and embed it into the context of refined topological string. The correspondence originally proposed from the common integrable structures in different field theories can be recast as a special limit of the refined geometric transition relating open and closed topological string partition functions. We realize the simplest examples of the correspondence explicitly in terms of open-closed geometric transition.

Pathways toward understanding Macroscopic Quantum Phenomena

description: Macroscopic quantum phenomena refer to quantum features in objects of `large' sizes, systems with many components or degrees of freedom, organized in ways where they can be identified as macroscopic objects. This emerging field is ushered in by several categories of definitive experiments in superconductivity, electromechanical systems, Bose-Einstein condensates and others. Yet this new field which is rich in open issues at the foundation of quantum and statistical physics remains little explored theoretically [1]. This talk summarizes our thoughts on attempting a systematic investigation into its foundation, with the goal of ultimately revealing or building a viable theoretical framework. Three major themes discussed in three intended essays are the large N expansion [2], the correlation hierarchy [3] and quantum entanglement [4]. We give a sketch of the first two themes and then discuss several key issues in the consideration of macro and quantum, namely, a) recognition that in a composite body there exist many 'levels of structure' characterized by collective variables. The quantum features of a macroscopic object can be captured by understanding how these collective variables function; b) 'quantum entanglement', an exclusively quantum feature [5], is known to persist to high temperatures [6] and large scales [7] under certain conditions, and may actually decrease with increased connectivity in a quantum network [8]. Here we use entanglement as a measure of quantumness and pick out these somewhat counter-intuitive examples to show that there are blind spots worthy of our attention and issues which we need to analyze closer. Our purpose is to try to remove the stigma that quantum only pertains to micro, in order to make way for deeper probes into the conditions whereby quantum features of macroscopic systems manifest.
