description: Galileon gravity offers a robust gravitational theory for explaining cosmic acceleration, having a rich phenomenology of testable behaviors. We explore three classes of Galileon models -- standard uncoupled, and linearly or derivatively coupled to matter -- investigating the expansion history with particular attention to early time and late time attractors, as well as the linear perturbations. From the relativistic and nonrelativistic Poisson equations we calculate the generalizations of the gravitational strength (Newton's constant), deriving its early and late time behavior. By scanning through the parameters we derive distributions of the gravitational strength at various epochs and trace the paths of gravity in its evolution. Using ghost-free and stability criteria we restrict the allowed parameter space, finding in particular that the linear and derivative coupled models are severely constrained by classical instabilities in the early universe.

description: Topological insulators are a novel class of quantum materials in which time-reversal symmetry, relativistic (spin-orbit) effects and an inverted band structure result in electronic metallic states on the surfaces of bulk crystals. These helical states exhibit a Dirac-like energy dispersion across the bulk bandgap, and they are topologically protected. Recent theoretical proposals have suggested the existence of topological crystalline insulators, a novel class of topological insulators in which crystalline symmetry replaces the role of time-reversal symmetry in topological protection [1,2]. In this study, we show that the narrow-gap semiconductor Pb(1-x)Sn(x)Se is a topological crystalline insulator for x=0.23. Temperature-dependent magnetotransport measurements and angle-resolved photoelectron spectroscopy demonstrate that the material undergoes a temperature-driven topological phase transition from a trivial insulator to a topological crystalline insulator. These experimental findings add a new class to the family of topological insulators. We expect these results to be the beginning of both a considerable body of additional research on topological crystalline insulators as well as detailed studies of topological phase transitions.

Insbesondere die Einkommen der privaten Haushalte – und damit der Konsum – kurbeln das Wachstum an, denn der Arbeitsmarkt läuft weiter rund: Die Arbeitslosenquote wird von 5,2 Prozent in diesem Jahr auf deutlich unter fünf Prozent im Jahr 2020 sinken – und damit auch zu kräftigeren Lohnanstiegen führen. Die Inflation bleibt indes mit knapp zwei Prozent moderat.

description: Nach einem starken zweiten Quartal scheint der globale Aufschwung allen Krisen zum Trotz intakt zu sein, insbesondere in den USA und im Euroraum. Das DIW Berlin erhöht daher seine Prognose für die Weltwirtschaft für das laufende Jahr geringfügig auf 4,2 Prozent. Im weiteren Verlauf dürften jedoch Sondereffekte in den USA wegfallen, sodass sich das Wachstum etwas entschleunigt. Für das kommende Jahr bleibt das DIW Berlin daher bei seiner Prognose vom Frühsommer, die ein Wachstum von 3,9 Prozent schätzte. Nach wie vor ist der private Konsum aufgrund der stabilen Lage auf den Arbeitsmärkten die wichtigste Stütze des Aufschwungs der Weltwirtschaft. Die Geldpolitik bleibt vorerst noch expansiv ausgerichtet, dies dürfte sich aber allmählich ändern. Eine Belastung für den Welthandel sind vor allem die Unsicherheiten über die US-Handelspolitik, was im weiteren Verlauf die Investitionen dämpfen dürfte. Weitere Risikofaktoren für die wirtschaftliche Entwicklung im Euroraum sind die künftige Politik der neuen italienischen Regierung und der drohende unregulierte Brexit. Von den Turbulenzen in der Türkei sind dagegen keine größeren Auswirkungen zu befürchten.

description: In this paper we explore noise tolerant learning of classifiers. We formulate the problem as follows. We assume that there is an ${\bf unobservable}$ training set which is noise-free. The actual training set given to the learning algorithm is obtained from this ideal data set by corrupting the class label of each example. The probability that the class label of an example is corrupted is a function of the feature vector of the example. This would account for most kinds of noisy data one encounters in practice. We say that a learning method is noise tolerant if the classifiers learnt with the ideal noise-free data and with noisy data, both have the same classification accuracy on the noise-free data. In this paper we analyze the noise tolerance properties of risk minimization (under different loss functions), which is a generic method for learning classifiers. We show that risk minimization under 0-1 loss function has impressive noise tolerance properties and that under squared error loss is tolerant only to uniform noise; risk minimization under other loss functions is not noise tolerant. We conclude the paper with some discussion on implications of these theoretical results.

description: We analyse the non-perturbative superpotential due to M5-brane instantons in F-theory compactifications on Calabi-Yau fourfolds. The M5 partition function is obtained via holomorphic factorisation by explicitly performing the sum over chiral 3-form fluxes. Comparison with the partition function of fluxed Euclidean D3-brane instantons in Type IIB orientifolds allows us to fix the spin structure on the intermediate Jacobian of the M5-instanton. We furthermore analyse the contribution of the M5-instanton to the superpotential in the presence of G4 gauge flux, where the superpotential is dressed with matter fields. We explicitly evaluate the pullback of G4 onto the M5-brane as a measure for the presence of charged instanton zero modes. This accounts for the M5 charge both under massless U(1)s, if present, and under what corresponds in Type II language to geometrically massive U(1)s.

Charge localization phenomena in correlated oxides
Creators: name: Comin, Riccardo
Publisher: name: University of British Columbia
Year: 2013

description: Charge segregation is very common in correlated oxides, spanning from the extreme limit of the Mott insulator, characterized by strong charge localization and suppressed charge dynamics, towards more mildly correlated states of matter, characterized by partial charge reorganization (charge-density-wave). In this thesis work I have investigated how the spatial organization of valence charge evolves with electrostatics (carrier doping) and chemistry (going down in the periodic table). For this reason, the focus is on the experimental study of the strongly-correlated 3d-oxides and the spin-orbit coupled 5d-oxides. These investigations have been performed with a bundle of state-of-the-art spectroscopic techniques in the field of quantum materials, namely: angle-resolved photoemission (ARPES), low-energy electron diffraction (LEED), resonant elastic X-ray scattering (REXS), X-ray diffraction (XRD), scanning tunnelling microscopy (STM) and optical spectroscopy. To support experimental data, we have used theoretical tools such as conventional density functional theory (DFT) for the 5d-oxides and developed ad-hoc approaches for the more complex 3d-materials. The all-around study of underdoped high-Tc Bi-based cuprates allowed us to shed new light on the universality and origin of charge-ordering instabilities in these materials and understand their interplay with superconductivity and pseudogap. These phenomena have been investigated in detail in underdoped samples of Bi2201, using a various experimental techniques (ARPES, REXS, XRD, LEED, STM) and various tailored theoretical approaches. The results of these studies are presented in Chapters 2 and 3. In the 5d-based iridates (in particular, Na₂IrO₃) we have revealed and characterized a novel form of Mott-Hubbard physics. This has been possible thanks to the combination of ARPES and optics for probing the electronic structure near the Fermi energy, and DFT for providing the theoretical framework to understand the electronic ground state in these materials. Ultimately, this approach helped demonstrate the crucial role of spin-orbit interaction in driving a novel Mott phase in materials where the Mott criterion might be violated (Chapter 4). Altogether, the resulting phenomena discovered in copper- and iridium based oxides have revealed novel unconventional aspects of the physics of correlated materials, thus paving the way for future explorations of the complex but fascinating jungle of transition metal oxides.

description: Hashtagbasierte Diskurse (insbesondere #regrettingmotherhood) und qualitative Befunde aus den Gender Studies deuten darauf hin, dass Mutterschaft einen schädigenden Einfluss auf das mentale Wohlbefinden hat. Analysen auf Basis der repräsentativen Längsschnittdaten des Sozio-oekonomischen Panels zeigen, dass es im Durchschnitt tatsächlich zu einem substanziellen und signifikanten Absinken des mentalen Wohlbefindens im Zeitraum bis sieben Jahre nach der Geburt kommt. Allerdings gibt es starke Unterschiede zwischen Müttern. 30 Prozent der untersuchten Mütter erfahren eine substanzielle Verschlechterung des gesundheitsbezogenen Wohlbefindens. Gleichzeitig profitieren aber auch 19 Prozent von einer substanziellen Verbesserung. Ein Vergleich mit kinderlosen Frauen legt nahe, dass zumindest ein Teil dieser Veränderungen genuin durch Mutterschaft und nicht sonstige altersbezogene Effekte erzeugt wird. Ob gesellschaftliche Mutterschaftsideale hierfür ursächlich sind, kann auf Basis des analytischen Ansatzes nicht mit Sicherheit festgestellt werden. Im Zusammenspiel mit entsprechenden Befunden aus der qualitativen Gender-Forschung legen die Ergebnisse allerdings nahe, dass eine institutionell gestützte Aufweichung tradierter Leitbilder von Mutterschaft zu einer psycho-emotionalen Entlastung von Müttern in Deutschland führen könnte.

description: Let X be a closed m-dimensional spin manifold which admits a metric of positive scalar curvature and let Pos(X) be the space of all such metrics. For any g in Pos(X), Hitchin used the KO-valued alpha-invariant to define a homomorphism A_{n-1} from π_{n-1}(Pos(X) to KO_{m+n}. He then showed that A_0 is not 0 if m = 8k or 8k+1 and that A_1 is not 0 if m = 8k-1 or 8$. In this paper we use Hitchin's methods and extend these results by proving that A_{8j+1-m} is not 0 whenever m>6 and 8j - m >= 0. The new input are elements with non-trivial alpha-invariant deep down in the Gromoll filtration of the group Γ^{n+1} = π_0(\Diff(D^n, \del)). We show that α(Γ^{8j+2}_{8j-5}) is not 0 for j>0. This information about elements existing deep in the Gromoll filtration is the second main new result of this note.

description: Using a recently suggested method of bosonization in an arbitrary dimension, we study the anomalous contribution of the low energy spin and charge excitations to thermodynamic quantities of a two-dimensional (2D) Fermi liquid. The method is slightly modified for the present purpose such that the effective supersymmetric action no longer contains the high energy degrees of freedom but still accounts for effects of the finite curvature of the Fermi surface. Calculating the anomalous contribution $δc(T)$ to the specific heat, we show that the leading logarithmic in temperature corrections to $δc(T)/T^2$ can be obtained in a scheme combining a summation of ladder diagrams and renormalization group equations. The final result is represented as the sum of two separate terms that can be interpreted as coming from singlet and triplet superconducting excitations. The latter may diverge in certain regions of the coupling constants, which should correspond to the formation of triplet Cooper pairs.

description: Context. The photometric signal we receive from a star hosting a planet is modulated by the variation of the planet signal with its orbital phase. Such phase variations are observed for transiting hot Jupiters with current instrumentation, and have also been measured for one transiting terrestrial planet (Kepler 10 b) and one non-transiting gas giant (Ups A b). Future telescopes (JWST and EChO) will have the capability to measure thermal phase curves of exoplanets including hot rocky planets in transiting and non-transiting configurations, and at different wavelengths. Short-period planets with a mass below 10 R_EARTH are indeed frequent and nearby targets (within 10 pc) are already known and more are to be found. Aims. To test the possibility to use multi-wavelengths infrared phase curves to constrain the radius, the albedo and the orbital inclination of a non-transiting planet with no atmosphere and on a 1:1 spin orbit resonance. Methods. We model the thermal emission of a synchronous rocky planet with no atmosphere and its apparent variation with the orbital phase for a given orbital inclination. We assume that the planet is detected by radial velocity so its orbital period and minimum mass are known. We simulate observed noisy phase curves and then apply a procedure to retrieve the radius and albedo of the planet and the inclination of the orbit. Results. Airless planets can be distinguished from planets having a dense atmosphere and their radius, albedo and inclination (and therefore true mass) can be retrieved from multiband observations with MIRI-JWST and EChO in the 5-15 μm range. [...] As inclination above 60° represents half of randomly oriented orbits, the growing population of short-period terrestrial-sized planets detected by radial velocity surveys and transits should offer several nearby promising targets for this method [...].

description: We investigate theoretically the PbTe/PbSnTe heterostructure grown in [111] direction, specifically a quantum wall (potential step of width d) of PbTe embedded in Pb_{1-x}Sn_{x}Te. For x large enough to lead to band inversion, and for large d, there are well-known gapless interface states associated with four L valleys. We show that for d \approx\ 10 nm the three pairs of states from oblique valleys strongly couple, and become gapped with a gap ~10 meV. On the other hand, the interface states from the [111] valley are essentially uncoupled, and they retain their helical character, remaining analogous to states at surfaces of thin layers of three-dimensional topological insulators. This opens up a possibility of studying the physics of two-dimensional helical Dirac fermions in heterostuctures of already widely studied IV-VI semicondcutors.

description: We compare the results of thirteen cosmological gasdynamical codes used to simulate the formation of a galaxy in the LCDM structure formation paradigm. The various runs differ in their hydrodynamical treatment (SPH, moving-mesh and AMR) but share the same initial conditions and adopt their latest published model of cooling, star formation and feedback. Despite the common halo assembly history, we find large code-to-code variations in the stellar mass, size, morphology and gas content of the galaxy at z=0, due mainly to the different implementations of feedback. Compared with observation, most codes tend to produce an overly massive galaxy, smaller and less gas-rich than typical spirals, with a massive bulge and a declining rotation curve. A stellar disk is discernible in most simulations, though its prominence varies widely from code to code. There is a well-defined trend between the effects of feedback and the severity of the disagreement with observation. Models that are more effective at limiting the baryonic mass of the galaxy come closer to matching observed galaxy scaling laws, but often to the detriment of the disk component. Our conclusions hold at two different numerical resolutions. Some differences can also be traced to the numerical techniques: more gas seems able to cool and become available for star formation in grid-based codes than in SPH. However, this effect is small compared to the variations induced by different feedback prescriptions. We conclude that state-of-the-art simulations cannot yet uniquely predict the properties of the baryonic component of a galaxy, even when the assembly history of its host halo is fully specified. Developing feedback algorithms that can effectively regulate the mass of a galaxy without hindering the formation of high-angular momentum stellar disks remains a challenge.

description: Die Zahl der Arbeitslosen, die Hartz IV beziehen, ist in den vergangenen zehn Jahren deutlich gesunken – und zwar stärker als die Arbeitslosigkeit generell. Obwohl ein großer Teil davon – inzwischen fast zwei Drittel – nicht über eine Berufsausbildung verfügt, haben vor allem wegen der guten Konjunktur doch viele eine Beschäftigung gefunden. Die Zahl aller Hilfebedürftigen hat sich indes kaum verändert, seit 2011 blieb sie konstant. Das liegt zum Teil daran, dass die Zahl der Erwerbstätigen, die ihren Verdienst mit Hartz-IV-Leistungen aufstocken müssen, kaum zurückgeht – trotz des gesetzlichen Mindestlohns. Vor allem aber macht sich ein starker Zuwachs an anerkannten Asylsuchenden bemerkbar. In diesem Zusammenhang hat auch die Zahl der bedürftigen Kinder zugenommen. In der politischen Debatte wird immer wieder gefordert, Hartz IV abzuschaffen. Überzeugende Alternativen sind allerdings nicht in Sicht. Initiativen, Hartz IV durch die öffentliche Förderung der Beschäftigung von Langzeitarbeitslosen zu ersetzen, greifen zu kurz, denn die Arbeitslosen stellen nur eine Minderheit der Bedürftigen.

description: We consider the thermoelectric properties of a double-quantum-dot molecule coupled in parallel to metal electrodes with a magnetic flux threading the ring. By means of the Sommerfeld expansion we obtain analytical expressions for the electric and thermal conductances, thermopower and figure of merit for arbitrary values of the magnetic flux. We neglect electronic correlations. The Fano antiresonances in transmission demand that terms usually discarded in the Sommerfeld expansion are taken into account. We also explore the behavior of the Lorenz ratio L=κ/σT, where κ and σ are the thermal and electrical conductances and T the absolute temperature, and we discuss the reasons why the Wiedemann-Franz law fails in presence of Fano antiresonances.

Remarks on the possible importance of jet v_3 and multiple jet production for the interpretation of recent jet quenching measurements at the LHC

description: Recent jet quenching measurements in Pb+Pb collisions at the LHC report a significant energy imbalance of di-jets. The imbalance is found to be compensated by a large amount of soft particles produced at large angles with respect to the di-jet axis. This observation questions the conventional picture of parton energy loss models, established at RHIC, which typically expect that the radiated gluons are emitted at moderate angles close to the outgoing parton. In this letter, we qualitatively discuss two possible contributions of the underlying heavy-ion background that may have to be taken into account when interpreting the recent data. We show that a large jet v_3, potentially caused by a pathlength dependent energy loss in the presence of fluctuating initial conditions, could contribute to the observed excess of soft particles apparently originating from large angle in-medium radiation. In addition, the observed excess could also be induced by multiple jets produced in the vicinity of the leading jet, caused by a potential selection bias imposed on the di-jet momentum imbalance.

description: Die Stromerzeugung aus Braun- und Steinkohle war im Jahr 2016 für mehr als ein Viertel der deutschen Treibhausgas- Emissionen verantwortlich. Unter den Bundesländern ist Nordrhein-Westfalen der mit Abstand größte CO2-Emittent. Um die nationalen Klimaziele zu erreichen, werden daher gegenwärtig alternative Kohleausstiegspfade diskutiert, unter anderem in der Kommission „Wachstum, Strukturwandel und Beschäftigung“, welche bis Ende 2018 konkrete Vorschläge vorlegen soll (sogenannte „Kohlekommission“). Gestützt auf detaillierte Modellrechnungen zeigt dieser Bericht, dass eine zügige Reduktion der Kohleverstromung in Deutschland und in Nordrhein-Westfalen notwendig ist, um die Klimaziele noch erreichen zu können – gemäß Klimaschutzplan der Bundesregierung bis 2030 eine Senkung der Emissionen im Energiesektor um gut 60 Prozent gegenüber 1990. Die Analyse zeigt auch, dass ein deutscher Kohleausstieg die Dekarbonisierung in Europa vorantreibt und den Ausbau erneuerbarer Energien in den Nachbarländern anreizen kann. Auch in Nordrhein-Westfalen ist der beschleunigte Kohleausstieg zur Erreichung der Klimaschutzziele notwendig. Sämtliche Braunkohlekraftwerke und viele Steinkohlekraftwerke können bis 2030 abgeschaltet werden. Das Auslaufen des Braunkohleabbaus in NRW kann so gestaltet werden, dass im Tagebau Garzweiler II keine zusätzlichen Ortschaften weichen müssen. Auch kann der schützenswerte Wald im Tagebau Hambach angesichts reduzierter Abbaumengen erhalten werden.

Maximum principle in linear finite element approximations of anisotropic diffusion-convection-reaction problems

description: A mesh condition is developed for linear finite element approximations of anisotropic diffusion-convection-reaction problems to satisfy a discrete maximum principle. Loosely speaking, the condition requires that the mesh be simplicial and $\mathcal{O}(\|\V{b}\|_\infty h + \|c\|_\infty h^2)$-nonobtuse when the dihedral angles are measured in the metric specified by the inverse of the diffusion matrix, where $h$ denotes the mesh size and $\V{b}$ and $c$ are the coefficients of the convection and reaction terms. In two dimensions, the condition can be replaced by a weaker mesh condition (an $\mathcal{O}(\|\V{b}\|_\infty h + \|c\|_\infty h^2)$ perturbation of a generalized Delaunay condition). These results include many existing mesh conditions as special cases. Numerical results are presented to verify the theoretical findings.
