The non-analytic momentum dependence of spin susceptibility of Heisenberg magnets in paramagnetic phase and its effect on critical exponents

description: We study momentum dependence of static magnetic susceptibility $χ(q)$ in paramagnetic phase of Heisenberg magnets and its relation to critical behavior within nonlinear sigma model (NLSM) at arbitrary dimension $25/2$. Using NLSM, we obtain the contribution of the"anomalous" term $ξ^{-2}f(qξ)$ to the critical exponent $ν$, comparing it to the contribution of the non-analytical dependence, originating from the critical exponent $η$ (the obtained critical exponents $ν$ and $η$ agree with previous studies). In the range $3\leq d<4$ we find that the former contribution dominates, and fully determines $1/N$ correction to the critical exponent $ν$ in the limit $d\rightarrow 4.$

description: In this paper we investigate the quintessence model with a minimally coupled scalar field in the context of recent supernovae observations. By choosing a particular form of the deceleration parameter q, which gives an early deceleration and late time acceleration for dust dominated model, we show that this sign flip in q can be obtained by a simple trigonometric patential. The early matter dominated model expands with q=1/2 as desired and enters a negative q phase quite late during the evolution.

description: A pilot plant to melt residual substances was operated over a period of more than four months. To examine any extreme situations, residues from incineration plants were used. The results obtained from these trials are very positive and encouraging for use in industrial applications. It has been achieved that the glass represents a satisfactory and long-term stable sink for major heavy metals, and another sink has been provided for other heavy metals through arrestment in a filter systems. Furthermore, any organic contaminants contained in the substances have been successfully destroyed. Contrary to conventional sheet glass melts, good performance and specific values have been confirmed. Using a special treatment technique, a major drawback involved with industrial residues, i.e., heterogeneity of basic material, has been reduced such that the future production of glass products with defined properties is considered to be possible. Preference is given to large-scale recovery in complex residues melting systems from a technological, economic and environmental point of view.

description: Industrial high-temperature processes like steel making, glass melting, cement production etc. need sintered or fused-cast refractory materials. During the operating time the reactions of the fused product and the bricks of the furnaces lead to contaminated refractory materials, which should no longer be disposed of and, therefore, have to be recycled, that means converted to raw materials for different industrial processes. Regarding these conditions the authors have tried to introduce silica bricks from the crown of glass melting furnaces and from the walls of coke ovens into the batch, replacing the glassmaking sand. First in laboratory-scale tests the melting behaviour and the optimum grain size distribution of ground silica bricks were studied. After a successful termination of these laboratory tests the results were transferred to an industrial furnace for melting container ware, replacing step by step the glass making sand without observing any stones or cords in the melted glass.
Probing internucleus potential with large-angle quasi-elastic scattering

description: Recent measurements for fusion cross section at energies around the Coulomb barrier have systematically indicated a significant deviation of fusion cross sections from a prediction of double-folding model. It has been argued that the deviation can be accounted for if one uses a large value of surface diffuseness parameter for a Woods-Saxon internuclear potential. We investigate this problem using large-angle quasi-elastic scattering, that is a good counterpart of fusion reaction. Towards a reconciliation of the apparent anomaly in the diffuseness parameter for fusion reactions, we also discuss possible ingredients which are missing in present nuclear reaction models. Those include a deviation from the frozen density approximation, the effect of antisymmetrization and the role of coordinate dependent moment of inertia for the relative motion between the colliding nuclei.

Modeling platinum-inclusion dissolution in phosphate laser glasses

Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 1995
Subjects: subject: 660

description: An analytic model is developed describing the dissolution of platinum inclusions in LHG-8 and LG-750 metaphosphate laser glasses. The model assumes a spherical geometry and a diffusion-limited rate process in a quiescent fluid. The time for complete dissolution of a platinum inclusion is proportional to the square of the inclusion radius and is computed to be about 10 h at 1100°C for inclusions 10 µm in diameter in these glasses. This agrees with experimental results. When melting in a platinum vessel, the dissolution of the crucible walls limits the size of the platinum inclusion that can be dissolved because of the background contribution to the ionic platinum content. This effect is included in the model and is related to the exposed surface-area-to-volume ratio of the platinum vessel.

description: For partially wetting, ellipsoidal colloids trapped at a fluid interface, their effective, interface--mediated interactions of capillary and fluctuation--induced type are analyzed. For contact angles different from 90$^o$, static interface deformations arise which lead to anisotropic capillary forces that are substantial already for micrometer--sized particles. The capillary problem is solved using an efficient perturbative treatment which allows a fast determination of the capillary interaction for all distances between and orientations of two particles. Besides static capillary forces, fluctuation--induced forces caused by thermally excited capillary waves arise at fluid interfaces. For the specific choice of a spatially fixed three--phase contact line, the asymptotic behavior of the fluctuation--induced force is determined analytically for both the close--distance and the long--distance regime and compared to numerical solutions.

description: Various parameters influencing the extractable gas content were investigated with the help of improved equipment for high-vacuum extraction experiments. Investigations of a tube melting tank, of the homogeneity of gas distribution in a TV screen and gob and of laboratory melts with different fining agents are described in detail. The different degassing behavior of different glass types are also described. It could be shown that the complex influence of technological and chemical factors determines the amount of physically and chemically dissolved gases. With experience in the analytical procedure, the use of statistical methods of data processing and the knowledge of technological parameters, it is possible to give hints for melting process control.

description: This paper studies numerically the Weeks-Chandler-Andersen (WCA) system, which is shown to obey hidden scale invariance with a density-scaling exponent that varies from below 5 to above 500. This unprecedented variation makes it advantageous to use the fourth-order Runge-Kutta algorithm for tracing out isomorphs. Good isomorph invariance of structure and dynamics is observed over more than three orders of magnitude temperature variation. For all state points studied, the virial potential-energy correlation coefficient and the density-scaling exponent are controlled mainly by the temperature. Based on the assumption of statistically independent pair interactions, a mean-field theory is developed that rationalizes this finding and provides an excellent fit to data at low temperatures and densities.

description: Using the SofI imager at ESO/NTT and NIRSPEC spectrograph at KeckII, we have obtained J,K images and echelle spectra covering the range 1.5 - 1.8 micron for the intermediate metallicity Bulge globular clusters NGC6539 and UKS1. We find [Fe/H]=-0.76 and -0.78, respectively, and an average alpha-enhancement of +0.44 dex and +0.31 dex, consistent with previous measurements of metal rich Bulge clusters, and favoring the scenario of rapid chemical enrichment. We also measure very low 12C/13C=4.5 +/-1 isotopic ratios in both clusters, suggesting that extra-mixing mechanisms due to cool bottom processing are at work during the evolution along the Red Giant Branch. Finally, we measure accurate radial velocities of =+31 +/-4Km/s and =+57 +/-6Km/s and velocity dispersion of about 8 Km/s and 11 Km/s for NGC6539 and UKS1, respectively.

description: An arrangement is a finite set of hyperplanes in a finite dimensional complex affine space. A complex rank one local system on the arrangement complement is determined by a set of complex weights for the hyperplanes. We study the Gauss-Manin connection for the moduli space of arrangements of fixed combinatorial type in the cohomology of the complement with coefficients in the local system determined by the weights. For nonresonant weights, we solve the eigenvalue problem for the endomorphisms arising in the 1-form associated to the Gauss-Manin connection.
Processability, crystallization and mechanical strength of P₂O₅-modified glasses and glass-ceramics in the system MgO-Al₂O₃-SiO₂-TiO₂

description: The crystallization behaviour and the processability of P₂O₅-modified glasses in the MgO-Al₂O₃-SiO₂-TiO₂ system were investigated. The hot-press furnace system "Empress IPS 500" was used to estimate the processability of the glasses. The crystallization process of the glasses was changed with increasing P₂O₅ content. The stability range of the α-quartz solid solution crystal phase decreases and cristobalite becomes the main crystalline phase in glass-ceramics with high P₂O₅ amounts. Magnesium orthophosphate was detected as a phosphorus-containing crystal phase. Glass-ceramics with high mechanical strength crystallize from these modified glasses. The investigations show that the high mechanical strength of the glass-ceramics is related to the crystallization of crystal phases with a high coefficient of thermal expansion.

description: Dynamic deflections have been used to determine in-place structural conditions of rigid pavements, based on modifications of principles and experience with the structural evaluation of flexible pavements. Details of the use of elastic layer theory to simulate deflection measurements associated with loadings for the Kentucky Road Rater are presented. Included is an illustration of the use of field deflection measurements to "back calculate" in-place moduli. The procedures are generally iterative and involve matching measured deflections with theoretical deflections. Elastic layer principles have been used to simulate deflections only at the mid slab position. Relationships regarding deflections at other locations on the slab currently involve empirical analyses. Evaluations involving the effects of pavement temperature, time of day, season, etc. are still empirical. In summary, major aspects of this report will be twofold. One will be related to procedures and principles applied to the use of deflections and layer elastic theory to estimate effective parameters representative of existing in-place pavement conditions. The second will be related to the application of deflection measurements and evaluation methodologies to determine appropriate recommendations of rehabilitation strategies and scheduling for rigid pavements.

description: The basic objective of this course is to provide background (introductory) technical information that will aid the manager of bridge/culvert installations. In most instances, information presented may not be sufficiently complete for the student to perform the required work. However, the intent is more to familiarize than to instruct In many instances, professional engineering and experienced labor are necessary to ensure successful completion of tasks. Once the local official responsible for bridges and culverts has completed this workshop, he should have a basic understanding of      the most common bridges/culverts encountered in counties and municipalities,     the major components of common bridge/culvert types and their functions,     common bridge/culvert materials,     material deterioration in bridge/culvert service,     various bridge/culvert maintenance requirements,     specific bridge/culvert rehabilitation techniques, and     decision-making procedures for bridge/culvert management

description: We consider theoretically the dynamics of exciton-polaritons in a zigzag chain of coupled elliptical micropillars subjected to incoherent excitation. The driven-dissipative nature of the system along with the naturally present polarization splitting inside the pillars gives rise to the non-reciprocal dynamics, which eventually leads to the non-Hermitian skin effect, where all the modes of the system collapse to one edge. As a result, the polaritons propagate only in one direction along the chain, independent of the excitation position, and the propagation in the opposite direction is suppressed. The system shows fair robustness against the typical disorder present in modern samples. Finally, using the bistable nature of the polaritons we show that information encoded in the bistability can be transferred only one way. This paves the way for compact and robust feedback-free one-dimensional polariton transmission channels without the need for an external magnetic field, which are compatible with proposals for polaritonic circuits.

On the Decay Modes $\bar{B_{d,s}^0} \to γD^{*0}$
Creators: name: Sørensen, J. O. Eeg J. A. Macdonald
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The various decay modes of the type $B \to γD^* $ are dynamically different. In general there are factorizable contributions, and there are pole diagrams and pseudoscalar exchange contributions at meson level. The purpose of this paper is to point out that the decay modes $\bar{B_{d,s}^0} \to γD^{*0} $ have negligible contributions from such mechanisms, in contrast to the decay modes $\bar{B_{d,s}^0} \to γ\bar{D^{*0}} $ and $B^- \to γD_{s,d}^{*-} $. However, for the decay modes $\bar{B_{d,s}^0} \to γD^{*0}$ there are non-factorizable contributions due to emision of soft gluons, and such non-factorizable contributions are found to dominate the amplitudes for these latter decay modes. We estimate the branching ratio for these modes in the heavy quark limits, both for the $b$- and the $c$- quarks, and obtain a value $ \simeq 1.6 \times 10^{-6}$ for $\bar{B_{d}^0} \to γD^{*0}$, and $ \simeq 8 \times 10^{-7}$ for $\bar{B_{s}^0} \to γD^{*0}$. We expect large corrections to this limit because the energy gap between the $b$- and $c$- quark masses are significantly bigger than 1 GeV. However, we expect that our estimate for $\bar{B_{d,s}^0} \to γD^{*0}$ gives the right order of magnitude for the {\em amplitudes}.

description: To combine the mechanical properties of high-strength base metals with the biological properties of bioactive materials, coatings of BIOVERIT® glasses and glass-ceramics on CoCr alloys and titanium have been produced. Different kinds of coating processes have been used: dipping, sputtering, plasma spraying, sintering and pasting. Dipping and pasting seem not to be suitable to produce layers because of cracks and low adhesion strength of the coatings (dipping) and the limitations in relation to the implant shape and the thickness of the layers (pasting). Using sputter techniques it is possible to produce dense layers ( < 10µim) with a high adhesion strength. Plasma spraying resuhed in layers with a thickness of 50 to 300µim, but during the plasma spraying process there is a partial evaporation of the highly volatile glass components. Sintering processes are very suitable to produce layers with a high adhesion strength; these layers are long term stable in simulated body fluid.

description: We show that the commonly adopted hot dark matter (HDM) bound on the axion mass $m_a \lesssim$ 1 eV is not reliable, since it is obtained by extrapolating the chiral expansion in a region where the effective field theory breaks down. This is explicitly shown via the calculation of the axion-pion thermalization rate at the next-to-leading order in chiral perturbation theory. We finally advocate a strategy for a sound extraction of the axion HDM bound via lattice QCD techniques.

description: Absorption-line spectroscopy of 23 background QSOs and numerous background galaxies has let us measure the spatial distribution of metals and neutral hydrogen around 1044 UV-selected galaxies at redshifts 1.8260 km/s) and produces very strong absorption lines (N_CIV >> 10^14 cm^-2) in the spectra of background objects. Absorption with an average column density of N_CIV ~ 10^14 cm^-2 extends to 80 kpc, a radius large enough to imply that most strong intergalactic CIV absorption is associated with star-forming galaxies like those in our sample. We find that the galaxy-CIV cross-correlation length increases with CIV column density and is similar to the galaxy-galaxy length (r_0 ~ 4 h^-1 Mpc) for N_CIV > 10^12.5 cm^-2. Distortions in the redshift-space galaxy-CIV correlation function on small scales may imply that some of the CIV systems have large peculiar velocities. Four of the five detected OVI absorption systems in our sample lie within 400 proper kpc of a known galaxy. Strong Lyman-a absorption is produced by the intergalactic gas within 1 h^-1 comoving Mpc of most galaxies, but for a significant minority (~1/3) the absorption is weak or absent. We were unable to identify any statistically significant differences between galaxies with weak nearby HI absorption and the rest, although galaxies with weak absorption may have higher star-formation rates. Galaxies near intergalactic CIV systems appear to reside in relatively dense environments and to have distinctive spectral energy distributions that are characterized by blue colors and young ages.

Ion-conducting properties of SiO₂ gels containing lithium salt

Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 1995
Subjects: subject: 660

description: Impedance spectroscopy was employed to characterize the electrical properties of lithium acetate and lithium chloride-containing SiO₂ gels. Gels with various lithium salt contents were prepared by mixing TEOS (tetraethylorthosilicate), ethanol, water, lithium salt and the corresponding acid (hydrochloric or acetic acid). The conductivity of the gels was measured on heating from ambient temperature up to 230 °C under dynamic vacuum and again on cooling. The conductivity of the as-prepared wet gels is dominated by the electrolyte solution in the pores. On cooling, the gels exhibit Arrhenius behaviour and examination of the electrical modulus data reveals that each sample possesses two thermally activated processes. Comparison with impedance measurements made on polycrystalline pellets of lithium acetate dihydrate and lithium chloride indicates that the higher impedance process is associated with the lithium salt. As a physical origin for the better conducting process, it is suggested that conduction takes place along the surface of the pores connecting crystalline regions. The trend in conductivity with composition of the LiCl-containing gels is analogous with that of ceramic composite electrolytes such as Lil-Al₂O₃ and Lil-SiO₂.

New algorithmic methods which efficiently compute geometric properties of the vacuum space of N=1 supersymmetric gauge theories are described. We illustrate the technique on subsectors of the MSSM. The fragility of geometric structure that we find in the moduli space motivates phenomenologically realistic deformations of the superpotential, while arguing against others. Special geometry in the vacuum may therefore signal the presence of string physics underlying the low-energy effective theory.

Circulation and cross-shelf exchanges over an irregular coastal topography
Creators: name: Eurin, David
Publisher: name: University of British Columbia
Year: 2009

description: The circulation and cross-shelf exchanges in a coastal ocean are studied using a primitive equation, non-linear, two-layer model with irregular bathymetry. Tracer advection is evaluated with the Tremback-Bott transport scheme and a post-treatment of the transport fluxes to achieve monotonicity. During upwelling events, alongshore variability of the topography, which here is mostly confined over the shelf-edge, is shown to have a first order effect on the circulation. The topography generates a countercurrent force on the deep flow. This effect is not reproduced by two-dimensional models. Enhanced cross-shelf mixing of passive scalar is also found at the shelf-edge. Rough shelf-breaks can be expected to generate more cross-shelf exchange of passive properties than smooth topographies during upwelling events. A stochastic wind stress forcing is applied to a barotropic version of the model in order to study the statistical equilibrium of the coastal ocean. The fundamental distinction between potential vorticity and passive scalar behavior in a vigorous eddy field is demonstrated. The cross-shelf gradient of eddy kinetic energy generates a strong upgradient pumping of potential vorticity over the shelf. Two mean alongshore jets are then observed. A poleward jet-arises at the shelf-break as predicted by the maximum entropy theory while an equatorward jet balances the momentum budget over the shelf. The passive scalar eddy-diffusivity exhibits large spatial variability. It is found to be qualitatively related to the eddy kinetic energy and the cross-shelf gradient of potential vorticity. It is shown that scalar concentration fronts naturally tend to form at the shelfedge. Small scale topography also locally enhances the cross-shelf passive scalar exchange by introducing some additional eddy kinetic energy into the velocity field.

The critical points are classified and determined explicitly. These results are applied for deriving the charge and spin transport, which have interesting physical features.

description: The German Federal Minister for Environment, Nature Protection and Reactor Safety (BMU) and the State Ministry for Environmental Affairs in Hannover sponsor projects in shop-floor size which demonstrate how equipment can be adopted to the latest technical developments to reduce environmental damages. At PLM Glashütte Münder such a project is being sponsored and expertly ac companied by the German Federal Bureau for Environment with funds being made available by the BMU and the State of Lower Saxony An important feature of the project is the technology to reduce NOₓ, values with the help of the Selective Catalytic Reduction (SCR) process. The DeNOx facility has been equipped with two ammonia water storage tanks having a capacity of 30 m³ each. The direct vaporizer is installed before the SCR reactor. The ammonia water is finely sprayed in with the two-material nozzle technique and mixed evenly with the flue gas volume flow. An analysis measuring device before and after the SCR reactor measures the relevant NOₓ values, these values are transformed into a signal which controls a valve supplying the required quantity of ammonia water. The conditioned flue gas volume is sent to the SCR reactor via guide systems. The reactor is equipped with two layers of catalyzers. To avoid bridge formation of dust that still accumulates in the purified gas flow, dust blowers are positioned above each catalyzer layer, which are activated at set intervals. First practical results show that with this technology NOₓ emissions can be reduced to values below 500 mg/m³ flue gas, where the NOₓ concentrations are based on dry flue gas in standard condition (1013 mbar, 273 K) with 8 % O₂.
Determination of the OH content of glasses

Subjects: subject: 660

description: The most widely used method for determination of the OH content of glasses is the IR spectroscopy. The absorption bands in the range of 2500 to 4000 cm⁻¹ are due to the fundamental stretching vibrations of OH groups having different degrees of association. The calibration of the absorption coefficient, α, of an OH band requires the determination of the absolute OH content of some samples by another method than IR spectroscopy. Comparing water outgassing method with ¹H NMR spectroscopy, a large difference in the OH content was observed. Therefore, it is more appropriate to use solely the absorption coefficient as a relative measure of the true OH content. If certain requirements are met, the quantitative analysis of the absorption coefficient of different glass samples is justified.

description: The ground state energy of the 2-D Wigner crystal is determined as a function of the thickness of the electron layer and the crystal structure. The method of evaluating the exchange-correlation energy is tested using known results for the infinitely-thin 2D system. Two methods, one based on the local-density approximation(LDA), and another based on the constant-density approximation (CDA) are established by comparing with quantum Monte-Carlo (QMC) results. The LDA and CDA estimates for the Wigner transition of the perfect 2D fluid are at $r_s=38$ and 32 respectively, compared with $r_s=35\pm5$ from QMC. For thick-2D layers as found in Hetero-junction-insulated-gate field-effect transistors, the LDA and CDA predictions of the Wigner transition are at $r_s=20.5$ and 15.5 respectively. Impurity effects are not considered here.

description: We present a comprehensive numerical study on the kinetics of phase transition that is characterized by two non-conserved scalar order parameters coupled by a special linear-quadratic interaction. This particular Ginzburg-Landau theory has been proposed to describe the coupled charge- and magnetic transition in nickelates and the collinear stripe phase in cuprates. The inhomogeneous state of such systems at low temperatures consists of magnetic domains separated by quasi-metallic domain-walls where the charge-order is reduced. By performing large-scale cell dynamics simulations, we find a two-stage phase-ordering process in which a short period of independent evolution of the two order parameters is followed by a correlated coarsening process. The long-time growth and coarsening of magnetic domains is shown to follow the Allen-Cahn power law. We further show that the nucleation-and-growth dynamics during phase transformation to the ordered states is well described by the Kolmogorov-Johnson-Mehl-Avrami theory in two dimensions. On the other hand, the presence of quasi-metallic magnetic domain walls in the ordered states gives rise to a very different kinetics for phase transition to the high temperature paramagnetic phase. In this new scenario, the phase transformation is initiated by the decay of magnetic domain walls into two insulator-metal boundaries, which subsequently move away from each other. Implications of our findings to recent nano-imaging experiments on nickelates are also discussed.

description: We analyze homogeneous, anisotropic cosmology driven by a self-interacting ``massive'' antisymmetric tensor field $B_{μν}$ which is present in string theories with D-branes. Time-dependent magnetic $B$ field existing in the early universe can lead to the Bianchi type I universe. Evolutions of such a tensor field are solved exactly or numerically in the universe dominated by vacuum energy, radiation, and $B$ field itself. The matter-like behavior of the $B$ field (dubbed as ``$B$-matter'') ensures that the anisotropy disappears at late time and thus becomes unobservable in a reasonable cosmological scenario. Such a feature should be contrasted to the cosmology of the conventional massless antisymmetric tensor field.

description: We discuss a cavity-QED scheme to deterministically generate entangled photons pairs by using a three-level atom successively coupled to two single longitudinal mode high-Q cavities presenting polarization degeneracy. The first cavity is prepared in a well defined Fock state with two photons with opposite circular polarizations while the second cavity remains in the vacuum state. A half-of-a-resonant Rabi oscillation in each cavity transfers one photon from the first to the second cavity, leaving the photons entangled in their polarization degree of freedom. The feasibility of this implementation and some practical considerations are discussed for both, microwave and optical regimes. In particular, Monte Carlo wave function simulations have been performed with state-of-the-art parameter values to evaluate the success probability of the cavity-QED source in producing entangled photon pairs as well as its entanglement capability.

Enamelling of glass by CO₂ laser treatment

description: Decoration of glass using enamel is interesting for hollow glassware as well as for flat glass sheets. Laser radiation can be used advantageously to increase the temperature of the product locally. The reactions which take place during CO₂ laser heat treatment of a conventional PbO-containing frit are discussed intensely. Pyrometrical temperature measurements accompany the experiments to investigate the temperature development during CO₂ laser irradiation. At temperatures above Tg optimal results concerning low surface roughness, high brightness and intensive colouration are obrained without deformation of the shape of the product. Very promising results show that higher temperatures can be achieved by laser application and therefore PbO-free frits can be used.
Abundances in red giant stars of NGC 2808 and correlations between chemical anomalies and global parameters in globular clusters

description: We present the abundance analysis of stars from the tip of the red giant branch (RGB) to below the RGB-bump in the globular cluster NGC 2808, based on high resolution echelle spectra. We derived abundances of Al, alpha-process elements (Si I, Ca I, Ti I and Ti II) and Fe-group elements (Sc II, V I, Cr I, Cr II, Mn I, Co I, Ni I). Apart from Mg being somewhat reduced, likely because it has been depleted at the expense of Al in the MgAl cycle, the other alpha-element ratios show the overabundance typical of halo stars of similar metallicity. Mn is underabundant, whereas Fe-group elements have typical abundance ratios near the solar value. We detect star-to-star differences in Al abundances from the RGB tip down to the faintest star below the RGB-bump, correlated with Na abundances at all luminosities. The slope of the Na-Al correlation is similar to the one found in M 13 by Sneden et al. (2004), but it is different from those in other globular clusters of similar metallicity. We find that the amount of chemical inhomogeneities along the Na-O and Mg-Al anticorrelations in globular cluster red giants is correlated with the present day cluster mass and ellipticity. Moreover, we find for the first time a correlation between the spread in proton-capture elements and orbital parameters of clusters. The chemical anomalies are more extended in clusters having large-sized orbits and longer periods, and in clusters with larger inclination angles of the orbit with respect to the Galactic plane.

Using the seismology of non-magnetic chemically peculiar stars as a probe of dynamical processes in stellar interiors

description: Chemical composition is a good tracer of hydrodynamical processes that occur in stars as they often lead to mixing and particle transport. By comparing abundances predicted by models and those observed in stars we can infer some constraints on those mixing processes. As pulsations in stars are often very sensitive to chemical composition, we can use asteroseismology to probe the internal chemical composition of stars where no direct observations are possible. In this paper I focus on main sequence stars Am, lambda bootis, and HgMn stars and discuss what we can learn of mixing processes in those stars from seismology.

description: The Hong-Ou-Mandel (HOM) dip plays an important role in recent linear optics experiments. It is crucial for quantum computing with photons and can be used to characterise the quality of single photon sources and linear optics setups. In this paper, we consider generalised HOM experiments with $N$ bosons or fermions passing simultaneously through a symmetric Bell multiport beam splitter. It is shown that for even numbers of bosons, the HOM dip occurs naturally in the coincidence detection in the output ports. In contrast, fermions always leave the setup separately exhibiting perfect coincidence detection. Our results can be used to verify or employ the quantum statistics of particles experimentally.

description: For the first time, glass centrifugal casting is analyzed by finite-element viscoplastic models. First of all, the sensitivity of the process parameters is analyzed on the radius lengthening of a glass gob during casting using central processing unit time-saving models. The suitability of glass for centrifuging is evaluated, taking its temperature, viscosity, mould rotation speed and time dependency, casting time and initial gob shape into account. A refined finite-element analysis of an NBS-710 plate production is then achieved. The results are used in decision-aid process design curves which allow the manufacturer to efficiently adjust process parameters with regard to the desired final shape.
