Sektorale Integration in den EU-Binnenmarkt – Zur „Nachfrageseite“ europäischer Energieaußenpolitik
Creators: name: Prange-Gstöhl, Heiko
Publisher: name: Österreichische Zeitschrift für Politikwissenschaft
Year: 2015

description: Warum sollten Länder ohne EU-Vollmitgliedschaftsperspektive eine rechtlich-verbindende sektorale Integration in den EU-Binnenmarkt „nachfragen“? Während EU-Kandidatenländer verpflichtet sind, den EU-Besitzstand bereits vor ihrem Beitritt zu übernehmen, und der Kandidatenstatus ihnen den notwendigen Anreiz hierfür bietet, argumentiere ich, dass Länder mit keiner oder nur vager Beitrittsperspektive eine vertiefte rechtliche Integration mit der EU „nachfragen“, wenn sie entweder darauf bedacht sind, ihre grundsätzliche EU-Beitrittsfähigkeit zu demonstrieren, größere Unabhängigkeit von einem regionalen Hegemon suchen oder sich signifikante wirtschaftliche Gewinne versprechen, da eine regulative Annäherung potenziell zu einer Steigerung des Handels und der Investitionen führt. Der vorliegende Artikel konzeptualisiert diese Frage anhand der EU-Energieaußenpolitik. Diese ist nicht nur durch eine hohe Regulierungsdichte gekennzeichnet, sondern auch durch ein spezifisches Rechtsinstrument für den Regelexport – die Europäische Energiegemeinschaft.

description: Lately, much attention has been given to quantum algorithms that solve pattern recognition tasks in machine learning. Many of these quantum machine learning algorithms try to implement classical models on large-scale universal quantum computers that have access to non-trivial subroutines such as Hamiltonian simulation, amplitude amplification and phase estimation. We approach the problem from the opposite direction and analyse a distance-based classifier that is realised by a simple quantum interference circuit. After state preparation, the circuit only consists of a Hadamard gate as well as two single-qubit measurements, and computes the distance between data points in quantum parallel. We demonstrate the proof-of-principle using the IBM Quantum Experience and analyse the performance of the classifier with numerical simulations, showing that it classifies surprisingly well for simple benchmark tasks.

description: Seit den russisch-ukrainischen Gaskonflikten der letzten Jahre wird sowohl in der wissenschaftlichen als auch in der politischen Diskussion wiederholt gefordert, die Europäische Union müsse eine kohärente energiepolitische Strategie verfolgen und ihre Interessen im Energiebereich verstärkt nach außen vertreten. Hierbei wird in sehr starkem Maße in klassischen geopolitischen Kategorien argumentiert. In diesem Beitrag soll stattdessen der Frage nach der Etablierung von energiepolitischen Organisationsprinzipien bzw. Normen in Drittländern unter Rückgriff auf das von Wolfers (1962) entwickelte Konzept der Milieuziele nachgegangen werden. Anders als die Mehrzahl der Beiträge zum externen Regieren der EU wird hier über den „bloßen“ Export von Normen, Regeln und Policies hinaus die bewusste Etablierung neuer Institutionen und Governance-Strukturen zur nachhaltigen Absicherung des betreffenden Normenexports – und damit auch der strategischen (Energie-) Interessen der EU – ins Zentrum der Analyse gestellt. Hierzu wird das Konzept des Polity- Shapings eingeführt und empirisch am Beispiel der Energiegemeinschaft untersucht.

description: The worldvolume theory of M5-branes on an ADE singularity $\mathbb{R}^5/Γ_G$ can be Higgsed in various ways, corresponding to the possible nilpotent orbits of $G$. In the F-theory dual picture, this corresponds to activating T-brane data along two stacks of 7-branes and yields a tensor branch realization for a large class of 6D SCFTs. In this paper, we show that the moduli spaces and anomalies of these T-brane theories are related in a simple, universal way to data of the nilpotent orbits. This often works in surprising ways and gives a nontrivial confirmation of the conjectured properties of T-branes in F-theory. We use this result to formally engineer a class of theories where the IIA picture naïvely breaks down. We also give a proof of the $a$-theorem for all RG flows within this class of T-brane theories.

description: In order to be efficient, spectroscopic galaxy redshift surveys do not obtain redshifts for all galaxies in the population targeted. The missing galaxies are often clustered, commonly leading to a lower proportion of successful observations in dense regions. One example is the close-pair issue for SDSS spectroscopic galaxy surveys, which have a deficit of pairs of observed galaxies with angular separation closer than the hardware limit on placing neighbouring fibers. Spatially clustered missing observations will exist in the next generations of surveys. Various schemes have previously been suggested to mitigate these effects, but none works for all situations. We argue that the solution is to link the missing galaxies to those observed with statistically equivalent clustering properties, and that the best way to do this is to rerun the targeting algorithm, varying the angular position of the observations. Provided that every pair has a non-zero probability of being observed in one realisation of the algorithm, then a pair-upweighting scheme linking targets to successful observations, can correct these issues. We present such a scheme, and demonstrate its validity using realisations of an idealised simple survey strategy.

description: Il XXI secolo è iniziato sotto il segno delle crisi: geopolitiche, finanziarie, sanitarie, climatiche, energetiche. In tempi in cui l’esplorazione di corpi celesti tocca vette formidabili, la conoscenza, la comprensione e la gestione dei pericoli naturali – qui ed ora, sulla Terra – pongono vecchi e nuovi (o nuovissimi) interrogativi alle società contemporanee. Le Scienze della Terra possiedono strumenti straordinari – di più: ineludibili – per studiare e contribuire ad affrontare le complessità del tempo presente e futuro, allo scopo di tutelare l’ambiente vitale, tanto nel suo ecosistema naturale quanto nelle sue necessità energetiche e strategiche. Non di un “altro pianeta” abbiamo dunque bisogno, bensì di conoscere e tutelare questo – sopra e sotto i nostri piedi –, attraverso l’intelletto e la valutazione nel lungo termine degli elementi necessari alla cosa più preziosa che conosciamo: la vita umana.

description: Abwertende Konstrukte machten aus „Türken“ Inbegriffe verschiedener Feindvorstellungen, „Aufklärer“ genauso wie „Bolschewiken“ und „Nationalsozialisten“. Wir konzentrieren uns auf eine systematische Neubewertung der Funktionsweise dieser an „Türken“ erinnernden Denkmäler in Wien, oder genauer, auf das Nachzeichnen der Geschichte der Inbesitznahme des öffentlichen Raumes mithilfe dieser Monumente. Wir analysieren die Umstände der Errichtung der Türkendenkmale, ihre Neubewertung und die Feierlichkeiten, die vor allem an Jahrestagen stattfanden. Die Analyse übersteigt die Ebene der Aneignung eines Denkmals in der Vergangenheit und ermöglicht eine kritische, distanzierte Reflexion. Reflexivität ist dabei das wichtigste Mittel, eine unkritische Reproduktion von Bildern über „den Feind“ zu verhindern. Denkmale haben inklusive und exklusive Funktionen. Sie besitzen identitätsstiftende und -erhaltende Bedeutung. Ausgangspunkte sind neue theoretische Bezugssysteme, um die dynamischen Veränderungen zu erfassen, die für die Funktionsweisen von Denkmalen typisch sind. Die Bedeutung dieser Vorgangsweise liegt darin, die vergangene Funktion der Denkmale und damit auch sie selbst als Orientierung einem kritischen Verhalten in der Gegenwart zugänglich zu machen.

description: We present a joint X-ray, optical and weak-lensing analysis for X-ray luminous galaxy clusters selected from the MCXC (Meta-Catalog of X-Ray Detected Clusters of Galaxies) cluster catalog in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey field with S16A data, As a pilot study of our planned series papers, we measure hydrostatic equilibrium (H.E.) masses using XMM-Newton data for four clusters in the current coverage area out of a sample of 22 MCXC clusters. We additionally analyze a non-MCXC cluster associated with one MCXC cluster. We show that H.E. masses for the MCXC clusters are correlated with cluster richness from the CAMIRA catalog (Oguri et al. 2017), while that for the non-MCXC cluster deviates from the scaling relation. The mass normalization of the relationship between the cluster richness and H.E. mass is compatible with one inferred by matching CAMIRA cluster abundance with a theoretical halo mass function. The mean gas mass fraction based on H.E. masses for the MCXC clusters is $\langle f_{\rm gas} \rangle = 0.125\pm0.012$ at spherical overdensity $Δ=500$, which is $\sim80-90$ percent of the cosmic mean baryon fraction, $Ω_b/Ω_m$, measured by cosmic microwave background experiments. We find that the mean baryon fraction estimated from X-ray and HSC-SSP optical data is comparable to $Ω_b/Ω_m$. A weak-lensing shear catalog of background galaxies, combined with photometric redshifts, is currently available only for three clusters in our sample. Hydrostatic equilibrium masses roughly agree with weak-lensing masses, albeit with large uncertainty. This study demonstrates that further multiwavelength study for a large sample of clusters using X-ray, HSC-SSP optical and weak lensing data will enable us to understand cluster physics and utilize cluster-based cosmology.

description: In today's engineering industries, there is a growing focus on sustainable and eco-friendly products due to their recyclability, abundant availability and property variability. One key aspect of this sustainability effort is the development of eco-friendly materials, particularly bio composites derived from agricultural waste residues. The physical, mechanical and thermal properties as well as suitability of these fibers depend greatly on the methods used for extraction, processing, chemical modification and physical treatments. Understanding these processes comprehensively is essential for obtaining desired natural fibers/fillers from agricultural waste for creating effective bio composites to meet specific application demands. This study aims to provide a comprehensive assessment of the various extraction and modification techniques employed for natural fibers. It offers an in-depth review of diverse extraction processes, ranging from the initial harvesting to the decortication stage. It has been revealed that the choice of extraction methodologies depends on climate, water resources, local traditions, and the desired fiber quality. Additionally, the paper explores chemical and physical treatments, highlighting how each method influences the structure and properties of natural fibers. Overall, this review offers practical insights into the steps taken to transform agro-waste biomass into desired natural fiber and in turn biocomposite material, while enhancing product quality and performance.
Demokratisierung des Wissens. Otto Neuraths politisches Projekt

Year: 2015

description: Das Verhältnis von Wissenschaft und Öffentlichkeit war ein zentrales Thema in Otto Neuraths Werk. Als Arbeiterbildner, Museumsdirektor und pädagogischer Erneuerer war die Auseinandersetzung mit diesem Thema für ihn auch eine Art Selbstreflexion. In diesem intellektuellen Prozess modifizierte er sein Verständnis von Demokratie und von seiner Rolle als Gelehrter und wissenschaftlicher Experte. Die Ausarbeitung seines politischen Projektes „Demokratisierung des Wissens“ beinhaltete auch einen kritischen Ansatz zur Rolle von Experten in politischen Kommunikations- und Entscheidungsprozessen. Der Beitrag diskutiert zunächst die Frage, ob Neurath als politischer Intellektueller gesehen werden kann. In diesem Zusammenhang werden die verschiedenen Phasen seines wissenschaftlichen Lebens gestreift um aufzuzeigen, dass er sowohl seine politische Rolle als auch sein politisches Selbstverständnis mehrfach änderte. Danach wird das zentrale politische Projekt – die Demokratisierung des Wissens – analysiert und historisch rekonstruiert, um abschließend zu zeigen, dass Neuraths Ansatz an deliberative und reflexive Modelle der Demokratietheorie anschlussfähig ist.

description: We present an analysis of the global and spatially-resolved Kennicutt-Schmidt (KS) star formation relation in the FIRE (Feedback In Realistic Environments) suite of cosmological simulations, including halos with $z = 0$ masses ranging from $10^{10}$ -- $10^{13}$ M$_{\odot}$. We show that the KS relation emerges and is robustly maintained due to the effects of feedback on local scales regulating star-forming gas, independent of the particular small-scale star formation prescriptions employed. We demonstrate that the time-averaged KS relation is relatively independent of redshift and spatial averaging scale, and that the star formation rate surface density is weakly dependent on metallicity and inversely dependent on orbital dynamical time. At constant star formation rate surface density, the `Cold \& Dense' gas surface density (gas with $T < 300$~K and $n > 10$~cm$^{-3}$, used as a proxy for the molecular gas surface density) of the simulated galaxies is $\sim$0.5~dex less than observed at $\sim$kpc scales. This discrepancy may arise from underestimates of the local column density at the particle-scale for the purposes of shielding in the simulations. Finally, we show that on scales larger than individual giant molecular clouds, the primary condition that determines whether star formation occurs is whether a patch of the galactic disk is thermally Toomre-unstable (not whether it is self-shielding): once a patch can no longer be thermally stabilized against fragmentation, it collapses, becomes self-shielding, cools, and forms stars, regardless of epoch or environment.

Using angular pair upweighting to improve 3D clustering measurements

description: Three dimensional galaxy clustering measurements provide a wealth of cosmological information. However, obtaining spectra of galaxies is expensive, and surveys often only measure redshifts for a subsample of a target galaxy population. Provided that the spectroscopic data is representative, we argue that angular pair upweighting should be used in these situations to improve the 3D clustering measurements. We present a toy model showing mathematically how such a weighting can improve measurements, and provide a practical example of its application using mocks created for the Baryon Oscillation Spectroscopic Survey (BOSS). Our analysis of mocks suggests that, if an angular clustering measurement is available over twice the area covered spectroscopically, weighting gives a $\sim$10-20% reduction of the variance of the monopole correlation function on the BAO scale.

description: We present the Ly$α$ luminosity functions (LFs) at $z=$5.7 and 6.6 derived from a new large sample of 1,266 Ly$α$ emitters (LAEs) identified in total areas of 14 and 21 deg$^2$, respectively, based on the early narrowband data of the Subaru/Hyper Suprime-Cam (HSC) survey. Together with careful Monte-Carlo simulations that account for the incompleteness of the LAE selection and the flux estimate systematics in the narrowband imaging, we have determined the Ly$α$ LFs with the unprecedentedly small statistical and systematic uncertainties in a wide Ly$α$ luminosity range of $10^{42.8-43.8}$ erg s$^{-1}$. We obtain the best-fit Schechter parameters of $L^{*}_{\rm Lya}=1.6^{+2.2}_{-0.6} (1.7^{+0.3}_{-0.7}) \times10^{43}$ erg s$^{-1}$, $ϕ^{*}_{\rm Lya}=0.85^{+1.87}_{-0.77}\ (0.47^{+1.44}_{-0.44})\times10^{-4}$ Mpc$^{-3}$, and $α=-2.6^{+0.6}_{-0.4}\ (-2.5^{+0.5}_{-0.5})$ at $z=5.7$ ($6.6$). We confirm that our best-estimate Ly$α$ LFs are consistent with the majority of the previous studies, but find that our Ly$α$ LFs do not agree with the high number densities of LAEs recently claimed by Matthee/Santos et al.'s studies that may overcorrect the incompleteness and the flux systematics. Our Ly$α$ LFs at $z=5.7$ and $6.6$ show an indication that the faint-end slope is very steep ($α\simeq -2.5$), although it is also possible that the bright-end LF results are enhanced by systematic effects such as the contribution from AGNs, blended merging galaxies, and/or large ionized bubbles around bright LAEs. Comparing our Ly$α$ LF measurements with four independent reionization models, we estimate the neutral hydrogen fraction of the IGM to be $x_{\rm HI}=0.3\pm0.2$ at $z=$6.6 that is consistent with the small Thomson scattering optical depth obtained by Planck 2016.

description: Aktive Arbeitsmarktpolitik (AAMP) spielt seit dem Beginn der 1990er-Jahre eine wichtige Rolle in der Arbeitsmarkt- und Beschäftigungsstrategie Österreichs. Dieser Beitrag beschäftigt sich mit der Entwicklung österreichischer aktiver Arbeitsmarktpolitik zwischen 1998 und 2007. Weiters wird das Verhältnis zwischen AAMP und geänderten Risikostrukturen – sogenannten „new social risks“ – näher beleuchtet. Da Resultate einer Politikfeldanalyse immer davon abhängen, vor welchem Hintergrund das jeweilige Politikfeld untersucht wird, leiten drei unterschiedliche Perspektiven die vorliegende Analyse der österreichischen aktiven Arbeitsmarktpolitik. Die Entwicklung der AAMP in Österreich wird zudem mithilfe zweier Hypothesen von Giuliano Bonoli theoretisch verortet. Diese beiden Hypothesen gründen auf dem Pfadabhängigkeitstheorem und dem Machtressourcenansatz.

description: Die formalen Mitwirkungsrechte des österreichischen Nationalrates garantieren eine starke Beteiligung in EU-Angelegenheiten. Eine Analyse der tatsächlichen Nutzung dieser Rechte legt den Schluss nahe, dass der parteipolitisch geprägte Handlungsverbund von Regierung und Regierungsparteien zu einer Deparlamentarisierung führt. Der vorliegende Beitrag argumentiert, dass eine Konzentration alleine auf die formalen Rechte der Rolle des Nationalrates nicht gerecht wird. Vielmehr hat sich in den beiden EU-Ausschüssen des Nationalrates im „Schatten bindender Stellungnahmen“ ein von Parteipolitik weitgehend befreites, konstruktives Arbeitsklima gebildet, in dem es weniger um das Verabschieden formeller Stellungnahmen, als um den Austausch an Informationen und Positionen geht. Wesentliche Bedingung für dafür, dass „bargaining“ durch „arguing“ ersetzt wird, ist ihr informeller Charakter sowie die weitgehende Abwesenheit der (Medien-) Öffentlichkeit.

Year: 2015

description: Ziel des vorliegenden Beitrages ist es, den Einfluss des Neoliberalismus auf (partei-)politische Programmatik zu analysieren. In diesem Kontext ermöglicht vor allem die programmatische Reaktion der Sozialdemokratie eine aussagekräftige Analyse – schließlich wäre es ein nicht zu unterschätzendes Kriterium für den Erfolg bzw. die Wirkmächtigkeit neoliberaler Hegemonie, wenn es gelingt, die Ausrichtung des zentralen traditionellen politischen Gegners liberaler Wirtschaftspolitik nachhaltig zu verändern. In diesem Sinne versucht dieser Beitrag die Wirkmächtigkeit neoliberalen Denkens durch einen panelhaft angelegten Vergleich der Programme vier sozialdemokratischer Parteien in Europa (Österreich, Deutschland, Schweiz und Großbritannien) zu illustrieren bzw. abzuschätzen. Zu diesem Zweck wird untersucht, ob sich zentrale wirtschaftspolitische Postulate sozialdemokratischer Parteien bezogen auf die Begriffe „Mensch“, „Markt“ und „Staat“ im Sinne des Neoliberalismus verändert haben. Es geht daher primär um die Frage, in welchem Ausmaß die viel diskutierte neoliberale Hegemonie Einfluss auf die grundsätzliche ideologische bzw. vor allem wirtschaftspolitische Ausrichtung der europäischen Sozialdemokratie ausübt.

description: Selective information transfer in spin ring networks by energy landscape shaping control has the property that the error 1-prob, where prob is the transfer success probability, and the sensitivity of the error to spin coupling uncertainties are statistically increasing across a family of controllers of increasing error. The need for a statistical Hypothesis Testing of a concordant trend is made necessary by the noisy behavior of the sensitivity versus the error as a consequence of the optimization of the controllers in a challenging error landscape. Here, we examine the concordant trend between the error and another measure of performance - the logarithmic sensitivity - used in robust control to formulate a well known fundamental limitation. Contrary to error versus sensitivity, the error versus logarithmic sensitivity trend is less obvious, because of the amplification of the noise due to the logarithmic normalization. This results in the Kendall τ test for rank correlation between the error and the log sensitivity to be somewhat pessimistic with marginal significance level. Here it is shown that the Jonckheere-Terpstra test, because it tests the Alternative Hypothesis of an ordering of the medians of some groups of log sensitivity data, alleviates this statistical problem. This identifies cases of concordant trend between the error and the logarithmic sensitivity, a highly anti-classical features that goes against the well know sensitivity versus complementary sensitivity limitation.

description: Wie wichtig sind Wahlen und die Parteizugehörigkeit von Regierungen für die Entwicklung des Aktienmarktes? Um diese Frage zu beantworten, liefert der vorliegende Beitrag eine kritische Bestandsaufnahme zur Wirkung von Politik auf Aktienmärkte. Nach einer kurzen Skizzierung jener beiden polit-ökonomischen Grundmodelle, die die Forschung zum Zusammenhang zwischen Politik und Aktienmarkt inspiriert haben, werden die Befunde empirischer Studien zu Wahlzyklus- und Parteieffekten vorgestellt und kritisch beleuchtet. Dabei wird insbesondere herausgearbeitet, warum die klassischen, vor dem Hintergrund des amerikanischen politischen Systems entwickelten polit-ökonomischen Modelle nicht ohne Weiteres auf andere Länder übertragbar sind und welche potenzielle Bedeutung institutionelle Charakteristika für den Einfluss von Politik auf Aktienmärkte haben. Der Aufsatz schließt mit einer Zusammenfassung und einigen Anmerkungen für weitere Forschungsanstrengungen.

description: The bi-Lipschitz geometry is one of the main subjects in the modern approach of Singularity Theory. However, it rises from works of important mathematicians of the last century, especially Zariski. In this work we investigate the Bi-Lipschitz equisingularity of families of Essentially Isolated Determinantal Singularities inspired by the approach of Mostowski and Gaffney.

description: The famous vanishing of the density of states (DOS) in a band gap, be it photonic or electronic, pertains to the infinite-crystal limit. In contrast, all experiments and device applications refer to finite crystals, which raises the question: Upon increasing the linear size $L$ of a crystal, how fast does the DOS approach the infinite-crystal limit? We present a theory for finite crystals that includes Bloch-mode broadening due to the presence of crystal boundaries. Our results demonstrate that the DOS for frequencies inside a band gap has a $1/L$ scale dependence for crystals in one, two and three dimensions.

description: Let $π$ traverse a sequence of cuspidal automorphic representations of GL(2) with large prime level, unramified central character and bounded infinity type. For G either of the groups GL(1) or PGL(2), let H(G) denote the assertion that subconvexity holds for G-twists of the adjoint $L$-function of $π$, with polynomial dependence upon the conductor of the twist. We show that H(GL(1)) implies H(PGL(2)). In geometric terms, H(PGL(2)) corresponds roughly to an instance of arithmetic quantum unique ergodicity with a power savings in the error term, H(GL(1)) to the special case in which the relevant sequence of measures is tested against an Eisenstein series.

Adaptively truncated Hilbert space based impurity solver for dynamical mean-field theory

description: We present an impurity solver based on adaptively truncated Hilbert spaces. The solver is particularly suitable for dynamical mean-field theory in circumstances where quantum Monte Carlo approaches are ineffective. It exploits the sparsity structure of quantum impurity models, in which the interactions couple only a small subset of the degrees of freedom. We further introduce an adaptive truncation of the particle or hole excited spaces, which enables computations of Green functions with an accuracy needed to avoid unphysical (sign change of imaginary part) self-energies. The method is benchmarked on the one-dimensional Hubbard model.

Exceptional field theories, superparticles in an enlarged 11D superspace and higher spin theories

description: Recently proposed exceptional field theories (EFTs) making manifest the duality $E_{n(n)}$ symmetry, first observed as nonlinearly realized symmetries of the maximal $d=3,4,...,9$ supergravity ($n=11-d$) and containing 11D and type IIB supergravity as sectors, were formulated in enlarged spacetimes. In the case of $E_{7(7)}$ EFT such an enlarged spacetime can be identified with the bosonic body of the $d=4$ central charge superspace $Σ^{(60|32)}$, the ${\cal N}=8$ $d=4$ superspace completed by 56 additional bosonic coordinates associated to central charges of the maximal $d=4$ supersymmetry algebra. In this paper we show how the hypothesis on the relation of all the known $E_{n(n)}$ EFTs, including $n=8$, with supersymmetry leads to the conjecture on existence of 11D exceptional field theory living in 11D tensorial central charge superspace $Σ^{(528|32)}$ and underlying all the $E_{n(n)}$ EFTs with $n=2,...,8$, and probably the double field theory (DFT). We conjecture the possible form of the section conditions of such an 11D EFT and show that quite generic solutions of these can be generated by superparticle models the ground states of which preserve from one half to all but one supersymmetry. The properties of these superparticle models are briefly discussed. We argue that, upon quantization, their quantum states should describe free massless non-conformal higher spin fields in D=11. We also discuss some relevant representations of the M-theory superalgebra which, in the present context, describes supersymmetry of the 11D EFT.

description: We propose a fully operational framework to study the non-equilibrium thermodynamics of a quantum system $S$ that is coupled to a detector $D$ whose state is continuously monitored, allowing to single out individual quantum trajectories of $S$. We focus on detailed fluctuation theorems and characterize the entropy production of the system. We establish fundamental differences with respect to the thermodynamic of unmonitored, unitarily evolved systems. We consider the paradigmatic example of circuit-QED, where superconducting qubits can be coupled to a continuously monitored resonator and show numerical simulations using state of the art experimental parameters.

Covariant field equations in supergravity

description: Covariance is a useful property for handling supergravity theories. In this paper, we prove a covariance property of supergravity field equations: under reasonable conditions, field equations of supergravity are covariant modulo other field equations. We prove that for any supergravity there exist such covariant equations of motion, other than the regular equations of motion, that are equivalent to the latter. The relations that we find between field equations and their covariant form can be used to obtain multiplets of field equations. In practice, the covariant field equations are easily found by simply covariantizing the ordinary field equations.

description: The $2$kth pseudomoments of the Riemann zeta function $ζ(s)$ are, following Conrey and Gamburd, the $2k$th integral moments of the partial sums of $ζ(s)$ on the critical line. For fixed $k>1/2$, these moments are known to grow like $(\log N)^{k^2}$, where $N$ is the length of the partial sum, but the true order of magnitude remains unknown when $k\le 1/2$. We deduce new Hardy--Littlewood inequalities and apply one of them to improve on an earlier asymptotic estimate when $k\to\infty$. In the case $k<1/2$, we consider pseudomoments of $ζ^α(s)$ for $α>1$ and the question of whether the lower bound $(\log N)^{k^2α^2}$ known from earlier work yields the true growth rate. Using ideas from recent work of Harper, Nikeghbali, and Radziwi{łł} and some probabilistic estimates of Harper, we obtain the somewhat unexpected result that these pseudomements are bounded below by $\log N$ to a power larger than $k^2α^2$ when $k<1/e$ and $N$ is sufficiently large.

Exponential improvement in photon storage fidelities using subradiance and "selective radiance" in atomic arrays

description: A central goal within quantum optics is to realize efficient interactions between photons and atoms. A fundamental limit in nearly all applications based on such systems arises from spontaneous emission, in which photons are absorbed by atoms and then re-scattered into undesired channels. In typical treatments of atomic ensembles, it is assumed that this re-scattering occurs independently, and at a rate given by a single isolated atom, which in turn gives rise to standard limits of fidelity in applications such as quantum memories or quantum gates. However, this assumption can be violated. In particular, spontaneous emission of a collective atomic excitation can be significantly suppressed through strong interference in emission. Thus far the physics underlying the phenomenon of subradiance and techniques to exploit it have not been well-understood. In this work, we provide a comprehensive treatment of this problem. First, we show that in ordered atomic arrays in free space, subradiant states acquire an interpretation in terms of optical modes that are guided by the array, which only emit due to scattering from the ends of the finite chain. We also elucidate the properties of subradiant states in the many-excitation limit. Finally, we introduce the new concept of selective radiance. Whereas subradiant states experience a reduced coupling to all optical modes, selectively radiant states are tailored to simultaneously radiate efficiently into a desired channel while scattering into undesired channels is suppressed, thus enabling an enhanced atom-light interface. We show that these states naturally appear in chains of atoms coupled to nanophotonic structures, and we analyze the performance of photon storage exploiting such states. We find that selectively radiant states allow for a photon storage error that scales exponentially better with number of atoms than previously known bounds.
