description: In the evaluation of novel scintillators, it is important to ensure that the spectrum of the light emitted by the scintillator is well matched to the response of the photomultiplier. In attempting to measure this spectrum using radioactive sources, it is found that so few photons are emitted per scintillation event that conventional spectroscopic techniques cannot easily be used. A simple photon counting technique is presented, using two photomultipliers operated in coincidence, the one viewing the scintillator directly, while the other views it through a monochromator. This system allows the spectrum to be measured without using specially cooled photomultipliers, intense radioactive sources or particle beams. © 2006 IOP Publishing Ltd.

description: We study topological properties of the correspondence of prime spectra associated with a non-commutative ring homomorphism R → S. Our main result provides criteria for the adjointness of certain functors between the categories of Zariski closed subsets of Spec R and Spec S; these functors arise naturally from restriction and extension of scalars. When R and S are left Noetherian, adjointness occurs only for centralizing and 'nearly centralizing' homomorphisms.
Electromagnetically induced transparency and dark fluorescence in a cascade three-level diatomic lithium system

Subjects: quant-ph

description: Following our previous brief report [Phys. Rev. Lett. 88, 173003 (2002)], we report here a detailed study of electromagnetically induced transparency (EIT) and dark fluorescence in a cascade three-level diatomic lithium system using optical-optical double resonance (OODR) spectroscopy for both resonance and off resonance coupling. When a strong coupling laser couples the intermediate state A Σu+1 (v=13,J=14) to the upper state G Πg1 (v=11,J=14) of Li27, the fluorescence from both A Σu+1 and G Πg1 states was drastically reduced as the weak probe laser was tuned through the resonance transition between the ground state X Σg+1 (v=4,J=15) and the excited state A Σu+1 (v=13,J=14). The strong coupling laser makes an optically thick medium transparent for the probe transition. In addition, the fact that fluorescence from the upper state G Πg1 (v=11,J=14) was also dark when both lasers were tuned at resonance implies that the molecules were trapped in the ground state. We used density matrix methods to simulate the response of an open molecular three-level system to the action of a strong coupling field and a weak probe field. The analytical solutions were obtained under the steady-state condition. We have incorporated the magnetic sublevel (M) degeneracy of the rotational levels in the line shape analysis and report |M| dependent line shape splitting. Our theoretical calculations are in excellent agreement with the observed fluorescence spectra. We show that the coherence is remarkably preserved even when the coupling field was detuned far from the resonance. © 2006 The American Physical Society.
Controlling polar molecules in optical lattices

Publisher: name: My University
Year: 2006
Subjects: quant-ph

description: We theoretically investigate the interaction of polar molecules with optical lattices and microwave fields. We demonstrate the existence of frequency windows in the optical domain where the complex internal structure of the molecule does not influence the trapping potential of the lattice. In such frequency windows the Franck-Condon factors are so small that near-resonant interaction of vibrational levels of the molecule with the lattice fields have a negligible contribution to the polarizability, and light-induced decoherences are kept to a minimum. In addition, we show that microwave fields can induce a tunable dipole-dipole interaction between ground-state rotationally symmetric (J=0) molecules. A combination of a carefully chosen lattice frequency and microwave-controlled interaction between molecules will enable trapping of polar molecules in a lattice and possibly realize molecular quantum logic gates. Our results are based on ab initio relativistic electronic structure calculations of the polar KRb and RbCs molecules combined with calculations of their rovibrational motion. © 2006 The American Physical Society.

description: A consistent description of the pi0 pi0 invariant mass distribution in the phi(1020) -> f0(980) gamma -> pi0 pi0 gamma decay and the pi0 eta in phi(1020) -> a0(980) gamma -> pi0 eta gamma is suggested. A search for the consequences of the flavor SU(3) symmetry for the scalar mesons can be based on such an analysis. In order to accurately treat the pseudoscalar meson dynamics, which is very important for the scalar meson decays, we employ Resonance Chiral Theory.

description: We have investigated shot noise in multiterminal, diffusive multiwalled carbon nanotubes (MWNTs) at 4.2 K over the frequency f = 600 - 850 MHz. Quantitative comparison of our data to semiclassical theory, based on non-equilibrium distribution functions, indicates that a major part of the noise is caused by a non-equilibrium state imposed by the contacts. Our data exhibits non-local shot noise across weakly transmitting contacts while a low-impedance contact eliminates such noise almost fully. We obtain F_{tube}< 0.03 for the intrinsic Fano factor of our MWNTs.

description: We demonstrate occurrence of bimodality and dynamical hysteresis in a system describing an overdamped quartic oscillator perturbed by additive white and asymmetric Lévy noise. Investigated estimators of the stationary probability density profiles display not only a turnover from unimodal to bimodal character but also a change in a relative stability of stationary states that depends on the asymmetry parameter of the underlying noise term. When varying the asymmetry parameter cyclically, the system exhibits a hysteresis in the occupation of a chosen stationary state.

description: Let X be a quasi-compact scheme, equipped with an open covering by affine schemes. A quasi-coherent sheaf on X gives rise, by taking sections over the covering sets, to a diagram of modules over the various coordinate rings. The resulting "twisted" diagram of modules satisfies a certain gluing condition, stating that the data is compatible with restriction to smaller open sets. In case X is a regular toric scheme over an arbitrary commutative ring, we prove that the unbounded derived category D(X) of quasi-coherent sheaves on X can be obtained from a category of twisted diagrams which do not necessarily satisfy any gluing condition by inverting maps which induce homology isomorphisms on hyper-derived inverse limits. Moreover, we given an explicit construction of a finite set of weak generators for the derived category. For example, if X is projective n-space then D(X) is generated by n+1 successive twists of the structure sheaf; the present paper gives a new homotopy-theoretic proof of this classical result. The approach taken uses the language of model categories, and the machinery of Bousfield-Hirschhorn colocalisation. The first step is to characterise colocal objects; these turn out to be homotopy sheaves in the sense that chain complexes over different open sets agree on intersections up to quasi-isomorphism only. In a second step it is shown that the homotopy category of homotopy sheaves is the derived category of X.

Three-Qubit Operators, the Split Cayley Hexagon of Order Two and Black Holes

description: The set of 63 real generalized Pauli matrices of three-qubits can be factored into two subsets of 35 symmetric and 28 antisymmetric elements. This splitting is shown to be completely embodied in the properties of the Fano plane; the elements of the former set being in a bijective correspondence with the 7 points, 7 lines and 21 flags, whereas those of the latter set having their counterparts in 28 anti-flags of the plane. This representation naturally extends to the one in terms of the split Cayley hexagon of order two. 63 points of the hexagon split into 9 orbits of 7 points (operators) each under the action of an automorphism of order 7. 63 lines of the hexagon carry three points each and represent the triples of operators such that the product of any two gives, up to a sign, the third one. Since this hexagon admits a full embedding in a projective 5-space over GF(2), the 35 symmetric operators are also found to answer to the points of a Klein quadric in such space. The 28 antisymmetric matrices can be associated with the 28 vertices of the Coxeter graph, one of two distinguished subgraphs of the hexagon. The PSL_{2}(7) subgroup of the automorphism group of the hexagon is discussed in detail and the Coxeter sub-geometry is found to be intricately related to the E_7-symmetric black-hole entropy formula in string theory. It is also conjectured that the full geometry/symmetry of the hexagon should manifest itself in the corresponding black-hole solutions. Finally, an intriguing analogy with the case of Hopf sphere fibrations and a link with coding theory are briefly mentioned.

description: 44. Chydorus pubescens Sars, 1901
Localities and specimens found: 50 – 7♀, 1♀ ov; 51 – 1♀.
Distribution and ecology. Chydorus pubescens is considered circumtropical (Smirnov 1996; Maiphae et al. 2008; Kotov et al. 2013a), but there are doubts about this (see Remarks for details) (Kotov et al. 2013b; Sinev & Korovchinsky 2013; Van Damme et al. 2013). In the Oriental region, to date, Ch. pubescens has been recorded in several countries (Michael & Sharma 1988; Sanoamuang 1998; Maiphae et al. 2005, 2008; Tanaka & Ohtaka 2010; Chatterjee et al. 2013; Korovchinsky 2013; Kotov et al. 2013b; Van Damme et al. 2013; Sharma & Sharma 2017; Tiang-nga et al. 2020; Choedchim & Maiphae 2023). In Vietnam, so far, it has only been discovered in the south, in Cat Tien National Park (Dong Nai province) (Sinev & Korovchinsky 2013; present study).
The lifestyle and ecology of the species are little studied. It was found in different lentic and lotic water bodies: rivers, streams, natural and man-made lakes, marshes, ponds, pools, peat swamps, etc. (Sanoamuang 1998; Maiphae et al. 2005; Sinev & Korovchinsky 2013; Choedchim & Maiphae 2023). Probably, Ch. pubescens is associated with aquatic vegetation (Tiang-nga et al. 2020). In our material, several individuals of this species were found only in the rhizosphere of floating plants (see Appendix 1).
Remarks. Chydorus pubescens was originally described in Brazil (Sars, 1901). Populations of this species found outside the Neotropics, and in particular in the Oriental area, may in fact represent other closely related species and still remain to be reviewed (Chatterjee et al. 2013; Kotov et al. 2013b; Sinev & Korovchinsky 2013; Van Damme et al. 2013). For instance, Ch. cf. pubescens, recorded by Idris & Fernando (1981) and Idris (1983) from Malaysia, actually refers to a recently described new member of the genus in the region, Ch. idrisi (Sinev 2014).

description: This paper is concerned with the subduction problem of type A quantum Iwahori-Hecke algebras $\mathbb{C} \mathbf{H}(\mathfrak{S}_f,q^2)$ with a real deformation parameter $q$, i.e. the problem of decomposing irreducible representations of such algebras as direct sum of irreducible representations of the subalgebras $\mathbb{C}\mathbf{H}(\mathfrak{S}_{f_1}, q^2) \times \mathbb{C}\mathbf{H}(\mathfrak{S}_{f_2}, q^2)$, with $f_1 + f_2 = f$. After giving a suitable combinatorial description for the subduction issue, we provide a selection rule, based on the Richardson-Littlewood criterion, which allows to determine the vanishing coupling coefficients between standard basis vectors for such representations, and we also present an equivariance condition for the subduction coefficients. Such results extend those ones corresponding to the subduction problem in symmetric group algebras $\mathbb{C}\mathfrak{S}_f \downarrow \mathbb{C}\mathfrak{S}_{f_1} \times \mathbb{C} \mathfrak{S}_{f_2}$ which are obtained by $q$ approaching the value 1.

Longitudinal diffusion at the thermal-limit was observed for drift fields up to at least 700 V/cm in all gas mixtures tested. The results are of particular interest in connection with mechanical simplification of the DRIFT direction-sensitive Dark Matter search, and for high energy physics experiments in which a low-Z, low density, gaseous tracking detector with no appreciable Lorentz drift is needed for operation in very high magnetic fields. © 2005 Elsevier B.V.

Azimuthal anisotropy in Cu+Au collisions at s NN =200 GeV

description: © 2018 American Physical Society. The azimuthal anisotropic flow of identified and unidentified charged particles has been systematically studied in Cu+Au collisions at sNN=200 GeV for harmonics n=1-4 in the pseudorapidity range |η|<1. The directed flow in Cu+Au collisions is compared with the rapidity-odd and, for the first time, the rapidity-even components of charged particle directed flow in Au+Au collisions at sNN=200 GeV. The slope of the directed flow pseudorapidity dependence in Cu+Au collisions is found to be similar to that in Au+Au collisions, with the intercept shifted toward positive pseudorapidity values, i.e., the Cu-going direction. The mean transverse momentum projected onto the spectator plane (px) in Cu+Au collision also exhibits approximately linear dependence on pseudorapidity with the intercept at about η≈-0.4 (shifted from zero in the Au-going direction), closer to the rapidity of the Cu+Au system center of mass. The observed dependencies find a natural explanation in a picture of the directed flow originating partly due the "tilted source" and partly due to the asymmetry in the initial density distribution. A charge dependence of (px) was also observed in Cu+Au collisions, consistent with an effect of the initial electric field created by charge difference of the spectator protons in two colliding nuclei. The rapidity-even component of directed flow in Au+Au collisions is close to that in Pb+Pb collisions at sNN=2.76 TeV, indicating a similar magnitude of dipolelike fluctuations in the initial-state density distribution. Higher harmonic flow in Cu+Au collisions exhibits similar trends to those observed in Au+Au and Pb+Pb collisions and is qualitatively reproduced by a viscous hydrodynamic model and a multiphase transport model. For all harmonics with n≥2 we observe an approximate scaling of vn with the number of constituent quarks; this scaling works as well in Cu+Au collisions as it does in Au+Au collisions.

description: We present a catalogue of 12CO(J=1-0) and 13CO(J=1-0) molecular clouds in the spatio-velocity range of the Carina Flare supershell, GSH 287+04-17. The data cover a region of ~66 square degrees and were taken with the NANTEN 4m telescope, at spatial and velocity resolutions of 2.6' and 0.1 km/s. Decomposition of the emission results in the identification of 156 12CO clouds and 60 13CO clouds, for which we provide observational and physical parameters. Previous work suggests the majority of the detected mass forms part of a comoving molecular cloud complex that is physically associated with the expanding shell. The cloud internal velocity dispersions, degree of virialization and size-linewidth relations are found to be consistent with those of other Galactic samples. However, the vertical distribution is heavily skewed towards high-altitudes. The robust association of high-z molecular clouds with a known supershell provides some observational backing for the theory that expanding shells contribute to the support of a high-altitude molecular layer.

description: The general parameterization of the quark-quark correlation function for a spin-12 hadron is considered. The presence of the Wilson line ensuring color gauge invariance of the correlator induces structures that were not given explicitly in the existing literature. In particular, the general form of the transverse momentum dependent correlator entering various hard scattering processes is derived. In this case two new time-reversal odd parton distributions appear at the twist-3 level. © 2005 Elsevier B.V. All rights reserved.

description: We consider the stability conditions for half-quantum vortices in quasi two dimensional $p_x+ip_y$ superconductor (such as ${\rm Sr_2 RuO_4}$ is believed to be) through energetics calculations. Although the predicted exotic nature of these excitations have recently attracted much attention but they have not been observed yet. We pay particular attention to the fact that an isolated half quantum vortex has a divergent energy cost in the bulk due to the associated {\it unscreened} spin current, which requires two half-quantum vortices with opposite spin winding to pair. We show that the stability of such a pair in bulk is enhanced when the ratio of spin superfluid density to superfluid density $ρ_{\rm sp}/ρ_{\rm s}$ is small. As a step towards stabilizing and observing these exotic excitations, we propose using various mesoscopic geometries. We find that certain mesoscopic geometries can selectively allow only single half-quantum vortices to enter the sample for small $ρ_{\rm sp}/ρ_{\rm s}$.

description: If the quantum numbers of the X(3872) are J^{PC}=1^{++}, the measurement of its mass implies that it is either a loosely-bound hadronic molecule whose constituents are a superposition of the charm mesons pairs D^{*0} Dbar^0 and D^0 Dbar^{*0} or else it is a virtual state of these charm mesons. Its binding energy is small enough that the decay width of a constituent D^{*0} or Dbar^{*0} has a significant effect on the line shapes of the X resonance. We develop a simple approximation to the line shapes that takes into account the effect of the D^{*0} width as well as inelastic scattering channels of the charm mesons. We carry out a simultaneous fit to the line shapes in the J/psi pi^+ pi^- and D^0 Dbar^0 pi^0 channels measured in the decays B^+ to K^+ + X by the Belle Collaboration. The best fit corresponds to the X(3872) being a bound state just below the D^{*0} Dbar^0 threshold, but a virtual state just above the D^{*0} D-ar^0 threshold is not excluded.

description: The vacuum energy density arising from the broken supersymmetry of the (standard-model) fields living on a brane cannot be fully "off-loaded" to the bulk: even assuming the existence of an effective "self-tuning" mechanism, a small fraction of the transferred energy "bunces back" to the brane, as a backreaction of the supersymmetry breaking gravitationally transmitted to the bulk. In that case the SUSY scale of the brane has to be bounded, to guarantee the consistency of such a residual energy density with current large-scale phenomonological constraints. This effect is illustrated by computing the zero-point energies of the tower of (higher-dimensional) massive states associated to tensor metric fluctuations on a brane embedded in a warped bulk geometry, and it is shown to be independent of the number of compact or non-compact extra dimensions.

description: The origin of the high-energy gamma-ray emission from the Milky Way center is still unclear and debated because of the impact of systematics afflicting the measurements from current experiments. Several theories and phenomenological models attempt to explain the intricate panorama. The presence of a PeVatron in the Central Molecular Zone or in its vicinity, the contribution of the hard-component of the diffuse gamma-ray emission, and dark matter annihilation scenario are among the most promising mechanisms for describing the observed excess. The development of increasingly precise models able to reproduce the measured gamma-ray emission is the challenge for the scientific community in view of the next generation telescopes. A detailed treatment of phenomenological models for the dubbed Cosmic Rays Sea (CR-sea) characterized by different configurations is scrutinized in comparison with the observed spectrum in the inner Galaxy, using DRAGON and GAMMASKY codes.

description: Echiniscus bigranulatus Richters, 1908
 This species exhibits a restricted distribution, consisting of South and Central America according to Michalczyk & Kaczmarek (2006), with it being widely distributed in Argentina (in the provinces of Buenos Aires, Misiones, Corrientes, Entre Ríos, Tucumán, Salta, Río Negro, Santa Cruz, and Tierra del Fuego) (Claps et al., 2008). Previously in a review of tardigrade distribution, McInnes (1994) cited its presence in Europe, Africa, Indonesia, and New Zealand.

description: 9. Azorella fuegiana Spegazzini (1896: 58).
Lectotype (designated here):— Spegazzini s.n. (LPS 12670 in LP002787!).
Protologue:—“ Hab. Non rara in dunis maritimis Punta Anegada et in scopulosis Chair Isl.”.
Notes:— Spegazzini does not cite a type, but in the protologue he indicates two localities for the new species: Punta Anegada, the northern extreme of the Isla Grande de Tierra del Fuego; and Chair Island, a small island from the archipelago. Both localities are part of the Región XII de Magallanes, Chile. We found one specimen at LP from Spegazzini´s herbarium with no information on place or date of collection, but with a label indicating “cotypus”, a word formerly used to indicate a syntype. The specimen agrees with the protologue in morphology and is the only original material found. Because this specimen likely constitutes one of the syntypes, we designate it as the lectotype of Azorella fuegiana.

description: The Sivers parton distribution function has been predicted to obey a particular "universality relation", namely, to have opposite sign in semi-inclusive deeply inelastic scattering (SIDIS) and the Drell-Yan process. We discuss how, on the basis of present HERMES data, this remarkable prediction of the QCD factorization approach to the description of single spin asymmetries related to the Sivers effect could be checked experimentally in future experiments at PAX and COMPASS. © 2005 Elsevier B.V.

description: 15. Azorella madreporica Clos (1847 [1848]: 79).
Lectotype (designated here):— CHILE. Coquimbo, Gay 513 (P00115308!).
Protologue:—“Esta planta se halla en las cordilleras de las provincias de Coquimbo ”.
Notes:—Clos, in the protologue of Azorella madreporica cites a collection from Coquimbo by Gay. We have found the following specimens that perfectly agree with the protologue and may correspond to original material (Gay s.n. G00359828, GH00075418, K000529591, K000529592; Gay 513 P00115308; Gay 1493 SGO000003657). Clos worked at P, but the specimens held in G, GH and K were donated by P no earlier than 1864 based on indications on the labels. Therefore, none can unambiguously be assigned as the holotype because all except the one housed at SGO, were available to Clos by the time he described the new species. We designate P00115308 as the lectotype of Azorella madreporica because it is the best preserved and with most abundant material. This specimen has a collection number (Gay 513) and the label indicates that it belongs to the third voyage of Gay (3 me. envoi.) to Chile, while the one at SGO has a different collection number (Gay 1493), and the ones at G, GH, and K do not have a collection number and the labels indicate that they belong to the first voyage of Gay (1 r. envoi) to Chile. Therefore, we do not consider these specimens duplicates of the lectotype selected.

description: Modern text simplification (TS) heavily relies on the availability of gold standard data to build machine learning models. However, existing studies show that parallel TS corpora contain inaccurate simplifications and incorrect alignments. Additionally, evaluation is usually performed by using metrics such as BLEU or SARI to compare system output to the gold standard. A major limitation is that these metrics do not match human judgements and the performance on different datasets and linguistic phenomena vary greatly. Furthermore, our research shows that the test and training subsets of parallel datasets differ significantly. In this work, we investigate existing TS corpora, providing new insights that will motivate the improvement of existing state-of-the-art TS evaluation methods. Our contributions include the analysis of TS corpora based on existing modifications used for simplification and an empirical study on TS models performance by using better-distributed datasets. We demonstrate that by improving the distribution of TS datasets, we can build more robust TS models.

Electronic structure of nanoscale iron oxide particles measured by scanning tunneling and photoelectron spectroscopies

description: We have investigated the electronic structure of nanosized iron oxide by scanning tunneling microscopy and spectroscopy as well as by photoelectron spectroscopy. The nanoparticles were produced by the thermal treatment of ferritin molecules containing a self-assembled core of iron oxide. Depending on the thermal treatment we were able to prepare different phases of iron oxide nanoparticles resembling γ- Fe2 O3, α- Fe2 O3, and a phase which apparently contains both γ- Fe2 O3 and α- Fe2 O3. The changes to the electronic structure of these materials were studied under reducing conditions. We show that the surface band gap of the electronic excitation spectrum can differ from that of bulk material and is dominated by surface effects. © 2005 The American Physical Society.

description: Within the framework of quantum memory channels we introduce the notion of repeatability of quantum channels. In particular, a quantum channel is called repeatable if there exist a memory device implementing the same channel on each individual input. We show that random unitary channels can be implemented in a repeatable fashion, whereas the nonunital channels cannot.

Einstein, incompleteness, and the epistemic view of quantum states

description: Does the quantum state represent reality or our knowledge of reality? In making this distinction precise, we are led to a novel classification of hidden variable models of quantum theory. Indeed, representatives of each class can be found among existing constructions for two-dimensional Hilbert spaces. Our approach also provides a fruitful new perspective on arguments for the nonlocality and incompleteness of quantum theory. Specifically, we show that for models wherein the quantum state has the status of something real, the failure of locality can be established through an argument considerably more straightforward than Bell's theorem. The historical significance of this result becomes evident when one recognizes that the same reasoning is present in Einstein's preferred argument for incompleteness, which dates back to 1935. This fact suggests that Einstein was seeking not just any completion of quantum theory, but one wherein quantum states are solely representative of our knowledge. Our hypothesis is supported by an analysis of Einstein's attempts to clarify his views on quantum theory and the circumstance of his otherwise puzzling abandonment of an even simpler argument for incompleteness from 1927.

description: We study the transport properties of a neutral graphene sheet with curved regions induced or stabilized by topological defects. The proposed model gives rise to Dirac fermions in a random magnetic field and in the random space dependent Fermi velocity induced by the curvature. This last term leads to singular long range correlated disorder with special characteristics. The Drude minimal conductivity at zero energy is found to be inversely proportional to the density of topological disorder, a signature of diffusive behavior.

For each of these gene families, multiple sequence alignments, phylogenetic trees, ratios of non-synonymous to synonymous nucleotide substitution rates (Ka/Ks), mappings from gene trees to the NCBI taxonomy and structural links to solved three-dimensional protein structures in the Protein Data Bank (PDB) with Grantham-weighted mutational factors were all calculated. Of the 'gene family trees', 173 embryophyte and 505 chordate branches show Ka/Ks ≫ 1 and are candidates for functional adaptation. The calculated information is available both as a gene family database and as a phylogenetically indexed resource, called 'The Adaptive Evolution Database' (TAED), available at http://www.bioinfo.no /tools/TAED. © Oxford University Press 2005; all rights reserved.
