On the Nature of Black Holes in Loop Quantum Gravity
Creators: name: Röken, Christian
Publisher: name: arXiv
Year: 2012
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A genuine notion of black holes can only be obtained in the fundamental framework of quantum gravity resolving the curvature singularities and giving an account of the statistical mechanical, microscopic degrees of freedom able to explain the black hole thermodynamical properties. As for all quantum systems, a quantum realization of black holes requires an operator algebra of the fundamental observables of the theory which is introduced in this study based on aspects of loop quantum gravity. From the eigenvalue spectra of the quantum operators for the black hole area, charge and angular momentum, it is demonstrated that a strict bound on the extensive parameters, different from the relation arising in classical general relativity, holds, implying that the extremal black hole state can neither be measured nor can its existence be proven. This is, as turns out, a result of the specific form of the chosen angular momentum operator and the corresponding eigenvalue spectrum, or rather the quantum measurement process of angular momentum. Quantum mechanical considerations and the lowest, non-zero eigenvalue of the loop quantum gravity black hole mass spectrum indicate, on the one hand, a physical Planck scale cutoff of the Hawking temperature law and, on the other hand, give upper and lower bounds on the numerical value of the Immirzi parameter. This analysis provides an approximative description of the behavior and the nature of quantum black holes.

description: Intensive theoretical studies have recently predicted that a Bose-Einstein condensate will exhibit a variety of novel properties if spin-orbit coupling is present. However, an unambiguous fact has also been pointed out: Rashba coupling destroys a condensate of noninteracting bosons even in high dimensions. Therefore, a conceptually important question arises as to whether or not a condensate exists in the presence of interaction and a general type of spin-orbit coupling. Here we show that interaction qualitatively changes the ground state of bosons under Rashba spin-orbit coupling. Any infinitesimal repulsion forces bosons either to condense at one or two momentum states or to form a superfragmented state that is a superposition of infinite numbers of fragmented condensates. The superfragmented state is unstable against the anisotropy of spin-orbit coupling in systems with large numbers of particles, leading to the revival of a condensate in current experiments.

description: The Beaufort Assessment Model (BAM) applies a statistical catch-age formulation implemented with the AD Model Builder software (Fournier et al. 2012) and fitted to multiple data sources simultaneously in a single integrated analysis (Maunder and Punt 2013). In essence, the model simulates a population forward in time while including fishing and biological processes (Quinn and Deriso 1999; Shertzer et al. 2014). Quantities to be estimated are systematically varied until characteristics of the simulated population match available data on the real population. Its basic structure is similar to that of other packages such as Stock Synthesis (Methot 2012; Methot and Wetzel 2013) and Age Structured Assessment Program (Legault 2008).

description: Consider a stable Lévy process $X=(X_t,t\geq 0)$ and let $T_x$, for $x>0$, denote the first passage time of $X$ above the level $x$. In this work, we give an alternative proof of the absolute continuity of the law of $T_x$ and we obtain a new expression for its density function. Our approach is elementary and provides a new insight into the study of the law of $T_x$. The random variable $T_x^0$, defined as the limit of $T_x$ when the corresponding overshoot tends to $0$, plays an important role in obtaining these results. Moreover, we establish a relation between the random variable $T_x^0$ and the dual process conditioned to die at $0$. This relation allows us to link the expression of the density function of the law of $T_x$ presented in this paper to the already known results on this topic.

description: A grounded theory study of intercultural encounters experienced by international students was carried out to contribute to an understanding of these events. Intercultural encounters are events which students perceive as having different cultural norms and practices. While there is considerable research regarding students’ experiences of overseas study, there have been relatively limited studies concerning student intercultural encounter experiences in an Australian context. This research used interviews to explore how international students at an Australian university prepared for study and investigates their experiences of intercultural encounters in the early months of their student lives. The intercultural encounters were explored in community, cultural, academic, service and social contexts. Analysis of the interview data identified three antecedents concerning the preparation for study: • Settling in arrangements - assistance with accommodation and living arrangements; • Student expectations -students’ expectations regarding overseas study; and • Proficiency in English - the ability to communicate in English. Three circumstantial intercultural encounter themes emerged from data analysis, namely: • Adjusting to diversity - international students experience a diversity of intercultural encounters in community, cultural, academic, service and social contexts; • Australia has wide ranging rules and regulations - Australia’s rules and regulations affected intercultural encounters in different contexts; and • Australia provides for quality of life - international students prefer to study in a country which provides quality of life benefits. Student reactions and outcomes arising from intercultural encounters were examined. The reactions can be immediate or considered and the outcomes can be described as affective, behavioural or cognitive outcomes. Furthermore the outcomes can contribute to an increased awareness of the new culture. This increased awareness may contribute to the development of intercultural competence which is the capacity to interact in intercultural situations. A model for the student intercultural encounter experience was developed that situates the results of this research within an experiential learning framework. The findings from this research can be used as a platform concerning further research into intercultural encounters. Recommendations enabling the application of the findings are provided for universities, government agencies and policy makers involved in international education.

description: Two groups are said to have the same nilpotent genus if they have the same nilpotent quotients. We answer four questions of Baumslag concerning nilpotent completions. (i) There exists a pair of finitely generated, residually torsion-free-nilpotent groups of the same nilpotent genus such that one is finitely presented and the other is not. (ii) There exists a pair of finitely presented, residually torsion-free-nilpotent groups of the same nilpotent genus such that one has a solvable conjugacy problem and the other does not. (iii) There exists a pair of finitely generated, residually torsion-free-nilpotent groups of the same nilpotent genus such that one has finitely generated second homology $H_2(-,\Z)$ and the other does not. (iv) A non-trivial normal subgroup of infinite index in a finitely generated parafree group cannot be finitely generated. In proving this last result, we establish that the first $L^2$ betti number of a finitely generated parafree group of rank $r$ is $r-1$. It follows that the reduced $C^*$-algebra of the group is simple if $r\ge 2$, and that a version of the Freiheitssatz holds for parafree groups.

Modelling the electronic structure and magnetic properties of LiFeAs and FeSe using hybrid-exchange density functional theory

description: The electronic structure and magnetic properties of LiFeAs and FeSe have been studied using hybrid exchange density functional theory. The total energies for a unit cell in LiFeAs and FeSe with different spin states including non-magnetic and spin-2 are calculated. The spin-2 configuration has the lower energy for both LiFeAs and FeSe. The computed anti-ferromagnetic exchange interactions between spins on the nearest (next nearest) neighbouring Fe atoms in LiFeAs and FeSe are approximately 14 (17) meV and 6 (13) meV respectively. The total energies of the checkerboard and stripe-type anti-ferromagnetic ordering for LiFeAs and FeSe are compared, yielding that for LiFeAs the checkerboard is lower whereas for FeSe the stripe-type is lower. However, owing to the fact that the exchange interaction of the next nearest neighbour is larger than that of the nearest one, which means that the collinear ordering might be the ground state. These results are in agreement with previous theoretical calculations and experiments. Especially the calculations for LiFeAs indicate a co-existence of conducting d-bands at the Fermi surface and d-orbital magnetism far below the Fermi surface. The theoretical results presented here might be useful for the experimentalists working on the electronic structure and magnetism of iron-based superconductors.

description: We investigate the effects of bulk impurities on the electronic spectrum of Weyl semimetals, a recently identified class of Dirac-type materials. Using a $T$-matrix approach, we study resonant scattering due to a localized impurity in tight binding versions of the continuum models recently discussed by Burkov, Hook, and Balents, describing perturbed four-component Dirac fermions in the vicinity of a critical point. The impurity potential is described by a strength $g$ as well as a matrix structure $Λ$. Unlike the case in d-wave superconductors, where a zero energy resonance can always be induced by varying the impurity scalar and/or magnetic impurity strength, we find that for certain types of impurity ($Λ$), the Weyl node is protected, and that a scalar impurity will induce an intragap resonance over a wide range of scattering strength. A general framework is developed to address this question, as well as to determine the dependence of resonance energy on the impurity strength.

description: We prove the rationality of all the minimal series principal W-algebras discovered by Frenkel, Kac and Wakimoto in 1992, thereby giving a new family of rational and C_2-cofinite vertex operator algebras. A key ingredient in our proof is the study of Zhu's algebra of simple W-algebras via the quantized Drinfeld-Sokolov reduction. We show that the functor of taking Zhu's algebra commutes with the reduction functor. Using this general fact we determine the maximal spectrums of the associated graded of Zhu's algebra of all the admissible affine vertex algebras as well.

description: Geometric Brownian motion (GBM) is a model for systems as varied as financial instruments and populations. The statistical properties of GBM are complicated by non-ergodicity, which can lead to ensemble averages exhibiting exponential growth while any individual trajectory collapses according to its time-average. A common tactic for bringing time averages closer to ensemble averages is diversification. In this letter we study the effects of diversification using the concept of ergodicity breaking.

description: By reducing core body temperature, T_c, induced hypothermia is a therapeutic tool to prevent brain damage resulting from physical trauma. However, all physiological systems begin to slow down due to hypothermia that in turn can result in increased risk of mortality. Therefore, quantification of the transition of T_c to early hypothermia is of great clinical interest. Conceptually, T_c may exhibit an either gradual or abrupt transition. Bent-cable regression is an appealing statistical tool to model such data due to the model's flexibility and greatly interpretable regression coefficients. It handles more flexibly models that traditionally have been handled by low-order polynomial models (for gradual transition) or piecewise linear changepoint models (for abrupt change). We consider a rat model for humans to quantify the temporal trend of T_c to primarily address the question: What is the critical time point associated with a breakdown in the compensatory mechanisms following the start of hypothermia therapy? To this end, we develop a Bayesian modelling framework for bent-cable regression of longitudinal data to simultaneously account for gradual and abrupt transitions. Our analysis reveals that: (a) about 39% of rats exhibit a gradual transition in T_c; (b) the critical time point is approximately the same regardless of transition type; (c) both transition types show a significant increase of T_c followed by a significant decrease.

description: Singlet fission, in which the optical spin-singlet exciton dissociates into two low energy triplet excitons, has been proposed as a viable approach to enhance the quantum efficiency of organic solar cells. We show that even when singlet fission is occurring in the donor molecule, the electronic structure at the donor$-$acceptor interface must satisfy specific requirements for the solar cell performance to be enhanced by this process. We focus on the pentacene$-$C$_{60}$ solar cell, and on the basis of our calculations and available experimental data, we conclude that there is not enough evidence that these requirements are met by the donor$-$acceptor interface here. We propose experiments that can determine whether the minimal requirement for enhanced performance driven by singlet fission is met in this and other solar cells.

description: The bulk breakdown behaviour of alumina single crystals with two different crystal orientations, {11-20}-plane (single crystal A) and {0001}-plane (single crystal C), have been studied. Therefor plan-parallel single crystal samples were electrically loaded until dielectric breakdown was achieved. For each crystal orientation, a characteristic breakdown channel direction through the sample could be defined. In C-oriented crystals the breakdown channel originated parallel to the c-axis. For A-oriented crystals however, the breakdown channel crossed the sample in an oblique direction; the angle between crystal surface and breakdown channel was 60°. Here, the breakdown channel crossed the sample along an A-plane. Although the breakdown channel paths of A and C crystals are different, the observed breakdown strength are identical within the scatter range.

description: We consider the unique infinite connected component of supercritical bond percolation on the square lattice and study the geometric properties of isoperimetric sets, i.e., sets with minimal boundary for a given volume. For almost every realization of the infinite connected component we prove that, as the volume of the isoperimetric set tends to infinity, its asymptotic shape can be characterized by an isoperimetric problem in the plane with respect to a particular norm. As an application we then show that the anchored isoperimetric profile with respect to a given point as well as the Cheeger constant of the giant component in finite boxes scale to deterministic quantities. This settles a conjecture of Itai Benjamini for the plane.

description: Das Wort Leib, ein Sondergut der deutschen Sprache, das in der Umgangssprache den lebendigen Körper meint, ist in der modernen Philosophie wichtig geworden aus Ungenügen an der traditionellen Zerlegung des Menschen in Körper und Seele (oder Geist, mentale Inhalte), wobei die Seele als Innenwelt abgesondert ist und mit der übrigen Welt nur durch den Körper zusammenhängt, während der Körper dem Bewussthaber zwar unmittelbar vor Augen steht, von diesem aber als Objekt der Betrachtung, Überlegung und Benutzung distanziert ist. Für das unmittelbare Betroffensein, mit dem das Wirkliche den Menschen nahegeht, sind beide Seiten nicht geeignet, die Seele nicht wegen ihrer Entlegenheit und Einkapselung, der Körper nicht wegen seiner Distanzierung. Man sucht im Menschen einen Treffpunkt für das unmittelbar Ergreifende, besonders auch im Raum, und braucht dafür auch den spürbaren Leib, der im leiblichaffektiven Betroffensein für das Ergreifende offen ist, das den Menschen zwingt, auf sich selbst zu achten, sei es durch das bloße Spüren oder auch mit Reflexion, weil er von etwas getroffen wird, das ihn auf sich selbst stößt. Daher ist für die moderne Leibphilosophie die Identifizierung des Menschen mit seinem Leib charakteristisch, weil man am Leiblichsein sich selbst merkt.

description: We characterize the near-IR sky background from 308 observations with the FIRE spectrograph at Magellan. A subset of 105 observations selected to minimize lunar and thermal effects gives a continuous, median spectrum from 0.83 to 2.5 microns which we present in electronic form. The data are used to characterize the broadband continuum emission between atmospheric OH features and correlate its properties with observing conditions such as lunar angle and time of night. We find that the moon contributes significantly to the inter-line continuum in the Y and J bands whereas the observed H band continuum is dominated by the blended Lorentzian wings of multiple OH line profiles even at R=6000. Lunar effects may be mitigated in Y and J through careful scheduling of observations, but the most ambitious near-IR programs will benefit from allocation during dark observing time if those observations are not limited by read noise. In Y and J our measured continuum exceeds space-based average estimates of the Zodiacal light, but it is not readily identified with known terrestrial foregrounds. If further measurements confirm such a fundamental background, it would impact requirements for OH-suppressed instruments operating in this regime.

Laufend wird ihre Unterstützung im Veranstaltungsprogramm benötigt, das die Badische Landesbibliothek und die Badische Bibliotheksgesellschaft nun seit Jahrzehnten gemeinsam durchführen und das den Mitgliedern der Bibliotheksgesellschaft vielfältige Ausstellungs‐, Konzert‐ und Vortragsaktivitäten anbietet, mit denen die Badische Landesbibliothek profiliert an die Öffentlichkeit tritt. Aber auch durch Förderung von Erwerbungs‐, Erschließung‐ und Restaurierungsmaßnahmen trägt die Badische Bibliotheksgesellschaft dazu bei, dass die Badische Landesbibliothek als Institution mit einer 500jährigen Geschichte und herausragenden Sammlungsbeständen ihre weithin anerkannte Arbeit als Kultureinrichtung leisten kann. Im Folgenden soll kurz über die vergangenen zehn Jahre berichtet werden.

description: We study dynamical phase transitions from antiferromagnetic to paramagnetic states driven by an interaction quench in the fermionic Hubbard model using the nonequilibrium dynamical mean-field theory. We identify two dynamical transition points where the relaxation behavior qualitatively changes: one corresponds to the thermal phase transition at which the order parameter decays critically slowly in a power law $\propto t^{-1/2}$, and the other is connected to the existence of nonthermal antiferromagnetic order in systems with effective temperature above the thermal critical temperature. The frequency of the amplitude mode extrapolates to zero as one approaches the nonthermal (quasi)critical point, and thermalization is significantly delayed by the trapping in the nonthermal state. A slow relaxation of the nonthermal order is followed by a faster thermalization process.
Urteilsbesprechung: EuGH C-595/17 und die Parallelproblematik in der Schiedsgerichtsbarkeit

description: Der Beitrag unterzieht die Entscheidung des EuGH in der Rechtssache eBizcuss und Apple einer kritischen Würdigung. Die Kernfrage des Falls lag darin, ob allgemein gefasste Gerichtsstandsklauseln auch kartelldeliktische Streitigkeiten erfassen. Dabei wird zunächst die Frage geklärt, ob der EuGH die Kompetenz hatte, Auslegungsleitlinien für Gerichtsstandsklauseln aufzustellen. In einem zweiten Schritt werden die Auslegungsleitlinien des EuGH einer kritischen Würdigung unterzogen und ein konstruktiver Gegenvorschlag unterbreitet. Außerdem beleuchtet der Beitrag die schiedsverfahrensrechtliche Parallelproblematik: Erfassen allgemein gefasste Schiedsabreden auch kartelldeliktische Streitigkeiten? This article critically examines the European Court of Justice’s (ECJ) decision in the case eBizcuss and Apple. The core question of the case was whether “normal” jurisdiction clauses encompass antirust claims as well. In its analysis, this article, first, answers the question whether it was within the ECJ’s competence to rule on the interpretation of jurisdiction clauses. In a second step, it critically assesses the ECJ’s interpretation guidelines and submits alternative interpretation guidelines. Additionally, the article explores the parallel question regarding arbitration clauses: Do “normal” arbitration clauses encompass antitrust claims as well?

Isotropic Heating of Galaxy Cluster Cores via Rapidly Reorienting AGN Jets

description: AGN jets carry more than sufficient energy to stave off catastrophic cooling of the intracluster medium (ICM) in the cores of cool-core clusters. However, in order to prevent catastrophic cooling, the ICM must be heated in a near-isotropic fashion and narrow bipolar jets with $P_{\rm jet}=10^{44-45}$ ergs/s, typical of radio AGNs at cluster centres, are inefficient at heating the gas in the transverse direction to the jets. We argue that due to existent conditions in cluster cores, the SMBHs will, in addition to accreting gas via radiatively inefficient flows, experience short stochastic episodes of enhanced accretion via thin discs. In general, the orientation of these accretion discs will be misaligned with the spin axis of the black holes and the ensuing torques will cause the black hole's spin axis (and therefore, the jet axis) to slew and rapidly change direction. This model not only explains recent observations showing successive generations of jet-lobes-bubbles in individual cool-core clusters that are offset from each other in the angular direction with respect to the cluster center, but also shows that AGN jets {\it can} heat the cluster core nearly isotropically on the gas cooling timescale. Our model {\it does} require that the SMBHs at the centers of cool-core clusters be spinning relatively slowly. Torques from individual misaligned discs are ineffective at tilting rapidly spinning black holes by more than a few degrees. Additionally, since SMBHs that host thin accretion discs will manifest as quasars, we predict that roughly 1--2 rich clusters within $z<0.5$ should have quasars at their centers.

description: Infinite determinantal measures introduced in this note are inductive limits of determinantal measures on an exhausting family of subsets of the phase space. Alternatively, an infinite determinantal measure can be described as a product of a determinantal process and a convergent, but not integrable, multiplicative functional. Theorem 2, the main result announced in this note, gives an explicit description for the ergodic decomposition of infinite Pickrell measures on the spaces of infinite complex matrices in terms of infinite determinantal measures obtained by finite-rank perturbations of Bessel point processes.
description: 22 pages. The main result stays the same, but the exposition in this new version has been substantially expanded, and the construction of infinite determinantal measures is now presented in slightly greater generality
Evolution and thermalization of dark matter axions in the condensed regime

description: We discuss the possibility that dark matter axions form a Bose-Einstein condensate (BEC) due to the gravitational self-interactions. The formation of BEC occurs in the condensed regime, where the transition rate between different momentum states is large compared to the energy exchanged in the transition. The time evolution of the quantum state occupation number of axions in the condensed regime is derived based on the in-in formalism. We recover the expression for the thermalization rate due to self interaction of the axion field, which was obtained in the other literature. It is also found that the leading order contributions for interactions between axions and other species vanish, which implies that the axion BEC does not give any significant modifications on standard cosmological parameters.

Linear-response theory of the longitudinal spin Seebeck effect

description: We theoretically investigate the longitudinal spin Seebeck effect, in which the spin current is injected from a ferromagnet into an attached nonmagnetic metal in a direction parallel to the temperature gradient. Using the fact that the phonon heat current flows intensely into the attached nonmagnetic metal in this particular configuration, we show that the sign of the spin injection signal in the longitudinal spin Seebeck effect can be opposite to that in the conventional transverse spin Seebeck effect when the electron-phonon interaction in the nonmagnetic metal is sufficiently large. Our linear-response approach can explain the sign reversal of the spin injection signal recently observed in the longitudinal spin Seebeck effect.

Lorentz Symmetry in QFT on Quantum Bianchi I Space-Time

description: We develop the quantum theory of a scalar field on LQC Bianchi I geometry. In particular, we focus on single modes of the field: the evolution equation is derived from the quantum scalar constraint, and it is shown that the same equation can be obtained from QFT on an "classical" effective geometry. We investigate the dependence of this effective space-time on the wavevector of the mode (which could in principle generate a deformation in local Lorentz-symmetry), focusing our attention on the dispersion relation. We prove that when we disregard backreaction no Lorentz-violation is present, despite the effective metric being different than the classical Bianchi I one. A preliminary analysis of the correction due to inclusion of backreaction is briefly discussed in the context of Born-Oppenheimer approximation.

description: To the full order in fermions, we construct D=10 type II supersymmetric double field theory. We spell the precise N=2 supersymmetry transformation rules as for 32 supercharges. The constructed action unifies type IIA and IIB supergravities in a manifestly covariant manner with respect to O(10,10) T-duality and a pair of local Lorentz groups, or Spin(1,9) \times Spin(9,1), besides the usual general covariance of supergravities or the generalized diffeomorphism. While the theory is unique, the solutions are twofold. Type IIA and IIB supergravities are identified as two different types of solutions rather than two different theories.

title: The Gregorios Manos collection of East Asian objects: connoisseurship, networks, and market dynamics in early twentieth-century Europe
Creators: name: Metoikidou, Maria
Publisher: name: University of Glasgow
Year: 2025

description: This thesis delves into the collection of East Asian objects assembled by Greek diplomat Gregorios Manos (1850-1928), during the late nineteenth and early twentieth centuries. Despite never travelling outside of Europe, Manos acquired thousands of objects, primarily from Japan and China, and is today regarded as the first Greek collector-scholar of Asian art. His efforts culminated in the establishment of the Sino-Japanese Museum in Corfu, now Corfu Museum of Asian Art, which remains the only Greek institution entirely devoted to the arts of Asia and the first of its kind in the Balkan space. By tracing the trajectory of Manos’ collection from fin-de-siècle Vienna, through its transfer to Paris, and eventually its establishment on the Greek island of Corfu, this thesis aims to reconstruct its history and shed light on unknown aspects of its formation.

This involves situating Manos and his collecting endeavours within a period that witnessed the influx of East Asian objects in Europe, particularly after the opening of Japan to foreign trade following the Treaty of Amity and Commerce (1858) and the socio-political shifts surrounding the demise of the Qing dynasty in 1911. These historical events had a profound impact on the dynamics of the European art market, the gradual development of scholarship, and the formation of collecting networks. Manos’ involvement is closely analysed within this context. Particularly the roles he assumed as buyer and consignor in public auctions illuminate his taste for Japanese and Chinese objects as well as his acquisition and selling strategies. Moreover, this thesis explores a previously unknown aspect of Manos’ engagement with the institutional sphere, specifically his role as a lender to major exhibitions that contributed towards a more scholarly approach to the study of Asian art.

Drawing on a broad range of archival material, this thesis not only constructs a portrait of Manos as a collector, but also delves into the histories of individual objects that both entered and departed from his collection. The lives of Japanese and Chinese items are examined within their original context as well as within the European environments they ended up residing, prompting reflections into issues of provenance, identity, and transformed meaning. Ultimately, my thesis elucidates Manos’ legacy and underscores the significance of research into lesser-known collections.
