description: An experiment to probe spin-polarized currents in the quantum Hall regime is suggested that takes advantage of the large Zeeman-splitting in the paramagnetic diluted magnetic semiconductor zinc manganese selenide (Zn$_{1-x}$Mn$_x$Se). In the proposed experiment spin-polarized electrons are injected by ZnMnSe-contacts into a gallium arsenide (GaAs) two-dimensional electron gas (2DEG) arranged in a Hall bar geometry. We calculated the resulting Hall resistance for this experimental setup within the framework of the Landauer-Büttiker formalism. These calculations predict for 100% spininjection through the ZnMnSe-contacts a Hall resistance twice as high as in the case of no spin-polarized injection of charge carriers into a 2DEG for filling factor $ν=2$. We also investigated the influence of the equilibration of the spin-polarized electrons within the 2DEG on the Hall resistance. In addition, in our model we expect no coupling between the contact and the 2DEG for odd filling factors of the 2DEG for 100% spininjection, because of the opposite sign of the g-factors of ZnMnSe and GaAs.

description: We calculate the Schur index of the ${\cal N}=4$ $U(N)$ SYM with finite $N$ via the AdS/CFT correspondence as the contribution of D3-branes wrapped on contractible cycles in $\boldsymbol{S}^5$ on some assumptions motivated by preliminary analyses. As far as we have checked numerically it agrees with the index calculated on the gauge theory side. In a certain limit it reproduces the analytic result given by Bourdier, Drukker, and Felix.

Non-destructive, dynamic detectors for Bose-Einstein condensates

description: We propose and analyze a series of non-destructive, dynamic detectors for Bose-Einstein condensates based on photo-detectors operating at the shot noise limit. These detectors are compatible with real time feedback to the condensate. The signal to noise ratio of different detection schemes are compared subject to the constraint of minimal heating due to photon absorption and spontaneous emission. This constraint leads to different optimal operating points for interference-based schemes. We find the somewhat counter-intuitive result that without the presence of a cavity, interferometry causes as much destruction as absorption for optically thin clouds. For optically thick clouds, cavity-free interferometry is superior to absorption, but it still cannot be made arbitrarily non-destructive . We propose a cavity-based measurement of atomic density which can in principle be made arbitrarily non-destructive for a given signal to noise ratio.

description: In an effort to understand ``rafts'' in biological membranes, we propose phenomenological models for saturated and unsaturated lipid mixtures, and lipid-cholesterol mixtures. We consider simple couplings between the local composition and internal membrane structure, and their influence on transitions between liquid and ``gel'' membrane phases. Assuming that the gel transition temperature of the saturated lipid is shifted by the presence of the unsaturated lipid, and that cholesterol acts as an external field on the chain melting transition, a variety of phase diagrams are obtained. The phase diagrams for binary mixtures of saturated/unsaturated lipids and lipid/cholesterol are in semi-quantitative agreement with the experiments. Our results also apply to regions in the ternary phase diagram of lipid/lipid/cholesterol systems.

description: We demonstrate the formation and trapping of different stationary solutions, oscillatory solutions, and rotating solutions of a polariton condensate in a planar semiconductor microcavity with a built-in ring-shaped potential well. Multistable ring shaped solutions are trapped in shallow potential wells. These solutions have the same ring shaped density distribution but different topological charges, corresponding to different orbital angular momentum (OAM) of the emitted light. For stronger confinement potentials, besides the fundamental modes, higher excited (dipole) modes can also be trapped. If two modes are excited simultaneously, their beating produces a complex oscillation and rotation dynamics. When the two modes have the same OAM, a double-ring solution forms for which the density oscillates between the inner and the outer ring. When the two modes have different OAM, a rotating solution with a crescent-shaped density and fractional OAM is created.

description: We study the contributions of the resonant states $K_0^{*}(1430)$ and $K_0^{*}(1950)$ in the three-body decays $B\to Kπh$ (with $h=π, K$) in the perturbative QCD approach. The crucial nonperturbative input $F_{Kπ}(s)$ in the distribution amplitudes of the $S$-wave $Kπ$ system is derived from the matrix element of vacuum to $Kπ$ pair. The $CP$ averaged branching fraction of the quasi-two-body decay process $B\to K^*_0(1950)h\to Kπh$ is about one order smaller than that of the corresponding decay $B\to K^*_0(1430)h\to Kπh$. In view of the important contribution from the $S$-wave $Kπ$ system for the $B\to Kπh$ decays, it is not appropriate to neglect the $K_0^{*}(1950)$ in the theoretical or experimental studies for the relevant three-body $B$ meson decays. The predictions in this work for the relevant decays are consistent with the existing experimental data.

description: Employing high-pressure infrared spectroscopy we unveil the Weyl semimetal phase of elemental Te and its topological properties. The linear frequency dependence of the optical conductivity provides clear evidence for metallization of trigonal tellurium (Te-I) and the linear band dispersion above 3.0 GPa. This semimetallic Weyl phase can be tuned by increasing pressure further: a kink separates two linear regimes in the optical conductivity (at 3.7 GPa), a signature proposed for Type-II Weyl semimetals with tilted cones; this however reveals a different origin in trigonal tellurium. Our density-functional calculations do not reveal any significant tilting and suggest that Te-I remains in the Type-I Weyl phase, but with two valence bandsin the vicinity of the Fermi level. Their interplay giving rise to the peculiar optical conductivity behavior with more than one linear regime. Pressure above 4.3 GPa stabilizes the more complex Te-II and Te-III polymorphs, which are robust metals.

"Algebraic truths" vs "geometric fantasies": Weierstrass' Response to Riemann

description: In the 1850s Weierstrass succeeded in solving the Jacobi inversion problem for the hyper-elliptic case, and claimed he was able to solve the general problem. At about the same time Riemann successfully applied the geometric methods that he set up in his thesis (1851) to the study of Abelian integrals, and the solution of Jacobi inversion problem. In response to Riemann's achievements, by the early 1860s Weierstrass began to build the theory of analytic functions in a systematic way on arithmetical foundations, and to present it in his lectures. According to Weierstrass, this theory provided the foundations of the whole of both elliptic and Abelian function theory, the latter being the ultimate goal of his mathematical work. Riemann's theory of complex functions seems to have been the background of Weierstrass's work and lectures. Weierstrass' unpublished correspondence with his former student Schwarz provides strong evidence of this. Many of Weierstrass' results, including his example of a continuous non-differentiable function as well as his counter-example to Dirichlet principle, were motivated by his criticism of Riemann's methods, and his distrust in Riemann's ``geometric fantasies''. Instead, he chose the power series approach because of his conviction that the theory of analytic functions had to be founded on simple "algebraic truths". Even though Weierstrass failed to build a satisfactory theory of functions of several complex variables, the contradiction between his and Riemann's geometric approach remained effective until the early decades of the 20$^{th}$ century.

description: The possibility of employing restricted Boltzmann machine (RBM) for collaborative filtering has been known for about a decade. However, there has been hardly any work on this topic since 2007. This work revisits the application of RBM in recommender systems. RBM based collaborative filtering only used the rating information; this is an unsupervised architecture. This work adds supervision by exploiting user demographic information and item metadata. A network is learned from the representation layer to the labels (metadata). The proposed label consistent RBM formulation improves significantly on the existing RBM based approach and yield results at par with the state-of-the-art latent factor based models.

description: The 2-D electron system (2DES) in Si metal-oxide field-effect transistors (MOSFETS) consists of two distinct electron fluids interacting with each other. We calculate the total energy as a function of the density $n$, and the spin polarization $ζ$ in the strongly-correlated low-density regime, using a classical mapping to a hypernetted-chain (CHNC) equation inclusive of bridge terms. Here the ten distribution functions, arising from spin and valley indices, are self-consistently calculated to obtain the total free energy, the chemical potential, the compressibility and the spin susceptibility. The T=0 results are compared with the 2-valley Quantum Monte Carlo (QMC) data of Conti et al. (at T=0, $ζ=0$) and found to be in excellent agreement. However, unlike in the one-valley 2DES, it is shown that {\it the unpolarized phase is always the stable phase in the 2-valley system}, right up to Wigner Crystallization at $r_s=42$. This leads to the insensitivity of $g^*$ to the spin polarization and to the density. The compressibility and the spin-susceptibility enhancement calculated from the free energy confirm the validity of a simple approach to the two-valley response based on coupled-mode formation. The three methods, QMC, CHNC, and Coupled-mode theory agree closely. Our results contain no {\it ad hoc} fit parameters. They agree with experiments and do not invoke impurity effects or metal-insulator transition phenomenology.

description: We study the trade-off relations satisfied by the genuine tripartite nonlocality in multipartite quantum systems. From the reduced three-qubit density matrices of the four-qubit generalized Greenberger-Horne-Zeilinger (GHZ) states and W states (4-qubit entangled state), we find that there exists a trade-off relation among the mean values of the Svetlichny operators associated with these reduced states. Namely, the genuine three-qubit nonlocalities are not independent. For four-qubit generalized GHZ states and W states, the summation of all their three-qubit maximal (squared) mean values of the Svetlichny operator has an upper bound. This bound is better than the one derived from the upper bounds of individual three-qubit mean values of the Svetlichny operator. Detailed examples are presented to illustrate the trade-off relation among the three-qubit nonlocalities.

description: We analyze two 3D general-relativistic magnetohydrodynamic accretion simulations in the context of how they would manifest in Event Horizon Telescope (EHT) observations of supermassive black holes. The two simulations differ only in whether the initial angular momentum of the plasma is aligned with the rapid (a = 0.9) spin of the black hole. Both have low net magnetic flux. Ray tracing is employed to generate resolved images of the synchrotron emission. When using parameters appropriate for Sgr A* and assuming a viewing angle aligned with the black hole spin, we find the most prominent difference is that the central shadow in the image is noticeably eccentric in tilted models, with the ring of emission relatively unchanged. Applying this procedure to M87 with a viewing angle based on the large-scale jet, we find that adding tilt increases the angular size of the ring for fixed black hole mass and distance, while at the same time increasing the number of bright spots in the image. Our findings illustrate observable features that can distinguish tilted from aligned flows. They also show that tilted models can be viable for M87, and that not accounting for tilt can bias inferences of physical parameters. Future modeling of horizon-scale observations should account for potential angular momentum misalignment, which is likely generic at the low accretion rates appropriate for EHT targets.

description: By using the Hartree-Fock-Bogoliubov equations within the Popov approximation, we investigate the thermodynamic properties of a dilute binary Bose-Fermi mixture confined in an isotropic harmonic trap. For mixtures with an attractive Bose-Fermi interaction we find a sizable enhancement of the condensate fraction and of the critical temperature of Bose-Einstein condensation with respect to the predictions for a pure interacting Bose gas. Conversely, the influence of the repulsive Bose-Fermi interaction is less pronounced. The possible relevance of our results in current experiments on trapped $^{87}{\rm Rb}-^{40}${\rm K} mixtures is discussed.

description: The Oxford Dartmouth Thirty Degree Survey (ODTS) is a deep, wide, multi-band imaging survey designed to cover a total of 30 square degrees in BVRi'Z, with a subset of U and K band data, in four separate fields of 5-10 deg^2 centred at 00:18:24 +34:52, 09:09:45 +40:50, 13:40:00 +02:30 and 16:39:30 +45:24. Observations have been made using the Wide Field Camera on the 2.5-m Isaac Newton Telescope in La Palma to average limiting depths (5 sigma Vega, aperture magnitudes) of U=24.8, B=25.6, V=25.0, R=24.6, and i'=23.5, with observations taken in ideal conditions reaching the target depths of U=25.3, B=26.2, V=25.7, R=25.4, and i'=24.6. The INT Z band data was found to be severely effected by fringing and, consequently, is now being obtained at the MDM observatory in Arizona. A complementary K-band survey has also been carried out at MDM, reaching an average depth of K_{5σ}~18.5. At present, approximately 23 deg^2 of the ODTS have been observed, with 3.5 deg^2 of the K band survey completed. This paper details the survey goals, field selection, observation strategy and data reduction procedure, focusing on the photometric calibration and catalogue construction. Preliminary photometric redshifts have been obtained for a subsample of the objects with R <= 23. These results are presented alongside a brief description of the photometric redshift determination technique used. The median redshift of the survey is estimated to be z~0.7 from a combination of the ODTS photometric redshifts and comparison with the redshift distributions of other surveys. Finally, galaxy number counts for the ODTS are presented which are found to be in excellent agreement with previous studies.

Chinese Communist Party Historiography of the 1911 Revolution, 1935-1976

description: Mao Zedong’s ascension to a position within the Chinese Communist Party (CCP)—unparalleled either before or since—was in part due to his ability to control the narration of history. Mao’s master narrative retold Chinese history so that it provided the foundation for Mao Zedong Thought and validated his power and policies. This thesis follows the creation, rise to prominence and ongoing revisions of this master narrative by examining its treatment of one, important historical event: the 1911 Revolution. I focus on the period of Mao’s leadership of the CCP between 1935 and 1976 in order to understand how his master narrative changed over time. Mao built his narrative of the 1911 Revolution around four themes: the United Front, the periodisation of history, class analysis and the unique nature of China. Each of these themes represents an aspect of Mao Zedong Thought. Changes in the relative prominence of these themes across the course of Mao’s life are related to changes in the way he sought to establish his power, the rise of perceived challenges to his revolutionary politics and power, changes in the policies that he was seeking to justify and changes in the nature of Mao Zedong Thought.
title: Welfare systems, ageing and work: an OECD perspective

description: This paper examines the scale of the demographic problem facing OECD economies and the labour market trends among older workers, considering the macroeconomic implications of welfare provision for ageing on living standards and fiscal balances. The nature and the scale of incentives for early retirement are then discussed, concluding that welfare systems in OECD countries will come under increasing pressure as the share of public pension payments on total welfare outlays could rise dramatically over the coming decades. The paper illustrates some of the recent OECD recommendations for responding to the challenges posed by ageing societies in the context of diverse social welfare systems and concludes that policies are urgently needed in a number of countries to pursue two fundamental objectives: increasing the average number of years individuals spend active in the labour force and raising the sources of provision for an adequate retirement income.

From quaternions to cosmology: spaces of constant curvature, ca. 1873-1925

description: After mathematicians and physicists had learned that the structure of physical space was not necessarily Euclidean, it became conceivable that the global topological structure of space was non-trivial. In the context of the late 19th century debates on physical space this speculation gave rise to the problem of classifying spaces of constant curvature from a topological point of view. William Kingdon Clifford, Felix Klein and Wilhelm Killing, the latter of whom devoted a substantial amount of work to the topic in the early 1890s, clearly perceived this problem as relevant for both mathematics and natural philosophy (i.e., physics or cosmology). To some extent, a cosmological interest may even be found among those authors who restated the space form problem in more modern terms in the early 20th century, such as Heinz Hopf.
Is there a reentrant glass in binary mixtures?

description: By employing computer simulations for a model binary mixture, we show that a reentrant glass transition upon adding a second component only occurs if the ratio $α$ of the short-time mobilities between the glass-forming component and the additive is sufficiently small. For $α\approx 1$, there is no reentrant glass, even if the size asymmetry between the two components is large, in accordance with two-component mode coupling theory. For $α\ll 1$, on the other hand, the reentrant glass is observed and reproduced only by an effective one-component mode coupling theory.

description: QUIC, as the foundation for HTTP/3, is becoming an Internet reality. A plethora of studies already show that QUIC excels beyond TCP+TLS+HTTP/2. Yet, these studies compare a highly optimized QUIC Web stack against an unoptimized TCP-based stack. In this paper, we bring TCP up to speed to perform an eye-level comparison. Instead of relying on technical metrics, we perform two extensive user studies to investigate QUIC's impact on the quality of experience. First, we investigate if users can distinguish two protocol versions in a direct comparison, and we find that QUIC is indeed rated faster than TCP and even a tuned TCP. Yet, our second study shows that this perceived performance increase does mostly not matter to the users, and they rate QUIC and TCP indistinguishable.

description: In this work we have considered the Taylor series expansion of the dynamic scaling relation of the magnetization with respect to small initial magnetization values in order to study the dynamic scaling behaviour of 2- and 3-dimensional Ising models. We have used the literature values of the critical exponents and of the new dynamic exponent $x_0$ to observe the dynamic finite-size scaling behaviour of the time evolution of the magnetization during early stages of the Monte Carlo simulation. For 3-dimensional Ising Model we have also presented that this method opens the possibility of calculating $z$ and $x_0$ separately. Our results show good agreement with the literature values. Measurements done on lattices with different sizes seem to give very good scaling.

description: The inorganic compound BiCu2PO6 contains tubelike structures, which are described magnetically by weakly coupled frustrated spin ladders with a finite energy gap. The elementary excitations are triplons of which the degeneracy is lifted due to Dzyaloshinskii-Moriya interactions. In certain regions of the Brillouin zone the lifetime of the triplon excitation modes becomes finite due to the hybridization of the single-triplon with the two-triplon states. In addition, the dispersions of these triplon modes show a striking down-bending before ceasing to exist. In experiment, BiCu2PO6 shows various types of decay processes, which can be caused by different symmetry breaking interactions. In previous studies, we established a minimal model to include all symmetry-allowed interactions, such as the Dzyaloshinskii-Moriya interaction. Based on this minimal model, we show in this thesis that isotropic and anisotropic effects are responsible for noticeable quasiparticle decay and certain down-shifts of the single-triplon energies. The analyses are based on a deepCUT approach for the isotropic case augmented by a perturbative treatment of the anisotropic couplings inducing quasiparticle decay at zero temperature.
description: Die anorganische Verbindung BiCu2PO6 enthält röhrenartige Strukturen, welche magnetisch durch schwach gekoppelte frustrierte Spinleitern mit einer endlichen Energielücke beschrieben werden. Die elementaren Anregungen sind Triplonen dessen Entartung aufgrund der Dzyaloshinskii-Moriya Wechselwirkungen aufgehoben ist. In bestimmten Bereichen der Brillouin Zone wird die Lebensdauer der Triplonen endlich aufgrund der Hybridisierung der Eintriplon- mit den Zweitriplonenzuständen. Zusätzlich zeigen diese Triplonmoden ein auffälliges Abknicken bevor sie aufhören zu existieren. Im Experiment weist BiCu2PO6 unterschiedliche Typen von Zerfallsprozessen auf, die durch verschiedene symmetriebrechende Wechselwirkungen verursacht sein könnten. In vorherigen Untersuchungen habe wir ein minimales Model aufgestellt, um alle aufgrund von Symmetrie erlaubten Wechselwirkungen, wie die Dzyaloshinskii-Moriya Wechselwirkung, zu berücksichtigen. Auf Grundlage dieses minimalen Models zeigen wir in dieser Arbeit, dass isotrope und anisotrope Effekte für erkennbaren Quasiteilchenzerfall und bestimmte Absenkungen der Eintriplonenenergien verantwortlich sind. Die Analysen basieren auf einem deepCUT Ansatz für den isotropen Fall, ergänzt durch eine störungstheoretische Behandlung der anisotropen Kopplungen, die Quasiteilchenzerfall bei Temperatur gleich Null induzieren.

description: Additional file 1. Thamnocephalus adds segments linearly. Segment number is plotted against time at one hour intervals and fit with a linear regression. Points are offset to demonstrate the high number of similar measures [72]; n = 20–30 individuals for each time point. Dotted line represents the first molting event at 4 hours. Solid lines represent the transition between tagma, thoracic to genital (~ 12 H) and genital to abdominal (~ 15 H). These data extend the linear rate shown in [37]. Those data were taken under less strictly controlled conditions.
Detection of the phase curve and occultation of WASP-100b with TESS

description: We report the detection of the full orbital phase curve and occultation of the hot-Jupiter WASP-100b using TESS photometry. The phase curve is isolated by suppressing low frequency stellar and instrumental modes using both a non-parametric harmonic notch filter (phasma) and semi-sector long polynomials. This yields a phase curve signal of (73 +/- 9) ppm amplitude, preferred over a null-model by deltaBIC = 25, indicating very strong evidence for an observed effect. We recover the occultation event with a suite of five temporally localized tools, including Gaussian processes and cosine filtering. This allows us to infer an occultation depth of (100 +/- 14) ppm, with an additional +/- 16 ppm systematic error from the differences between methods. We regress a model including atmospheric reflection, emission, ellipsoidal variations and Doppler beaming to the combined phase curve and occultation data. This allows us to infer that WASP-100b has a geometric albedo of A_g = 0.16 (+0.04, -0.03) in the TESS bandpass, with a maximum dayside brightness temperature of (2710 +/- 100) K and a warm nightside temperature of (2380 [+170, -200]) K. Additionally, we find evidence that WASP-100b has a high thermal redistribution efficiency, manifesting as a substantial eastward hotspot offset of (71 [+2, -4]) degrees. These results present the first measurement of a thermal phase shift among the phase curves observed by TESS so far, and challenge the predicted efficiency of heat transport in the atmospheres of ultra-hot Jupiters.
