Mass modification of itinerant carriers in RKKY oscillations induced by finite range exchange interactions

description: We investigate the Ruderman-Kittel-Kasuya-Yosida oscillations of the itinerant carrier spin density in a system where those oscillations appear only due to a finite distribution of a localized spin. The system represents a half-infinite one-dimensional quantum wire with a magnetic impurity located at its edge. In contrast to the conventional model of a point-like exchange interaction the itinerant carrier spin density oscillations in this system exist. We {\it analytically} demonstrate that when the radius of the exchange interaction is less than the wave length of the itinerant carriers living on the Fermi surface, the long range behavior of the oscillations is identical to the one taking place in the zero radius limit of the same exchange interaction but for an infinite one-dimensional quantum wire where, in comparison with the original half-infinite system, the mass of the itinerant carriers is {\it strongly} modified by the exchange interaction radius. On the basis of our analysis we make a suggestion on directionality of surface Ruderman-Kittel-Kasuya-Yosida interaction shown in recent experiments: we believe that in general the anisotropy of the Ruderman-Kittel-Kasuya-Yosida interaction could result not only from the anisotropy of the {\it Fermi surface} of itinerant carriers but also from the anisotropy of the {\it spin carrying atomic orbitals} of magnetic impurities.

Gravitational wave emission from rotating superfluid neutron stars

description: In this paper we investigate the effect of a pinned superfluid component on the gravitational wave emission of a steadily rotating deformed neutron star. We show that the superfluid pinning allows the possibility for there to be gravitational wave emission at both the stellar spin frequency $Ω$ and its first harmonic, $2Ω$. This contrasts with the conventional case where there is no pinned superfluidity, where either only the $2Ω$ harmonic is present, or else the star undergoes precession, a feature which is not believed to be common in the known pulsar population. This work motivates the carrying out of gravitational wave searches where both the $Ω$ and $2Ω$ harmonics are searched for, even in targeted searches for waves from known pulsars which aren't observed to precess. Observation of such a two-component signal would provide evidence in favour of pinned superfluidity inside the star.

Young tableaux and the Steenrod algebra

Subjects: subject: Algebraic Topology (math.AT)

subject: 55S10, 20C20

description: The purpose of this paper is to forge a direct link between the hit problem for the action of the Steenrod algebra A on the polynomial algebra P(n)=F_2[x_1,...,x_n], over the field F_2 of two elements, and semistandard Young tableaux as they apply to the modular representation theory of the general linear group GL(n,F_2). The cohits Q^d(n)=P^d(n)/P^d(n)\cap A^+(P(n)) form a modular representation of GL(n,F_2) and the hit problem is to analyze this module. In certain generic degrees d we show how the semistandard Young tableaux can be used to index a set of monomials which span Q^d(n). The hook formula, which calculates the number of semistandard Young tableaux, then gives an upper bound for the dimension of Q^d(n). In the particular degree d where the Steinberg module appears for the first time in P(n) the upper bound is exact and Q^d(n) can then be identified with the Steinberg module.

description: We perform a quantitative simulation of the repulsive Fermi-Hubbard model using an ultracold gas trapped in an optical lattice. The entropy of the system is determined by comparing accurate measurements of the equilibrium double occupancy with theoretical calculations over a wide range of parameters. We demonstrate the applicability of both high-temperature series and dynamical mean-field theory to obtain quantitative agreement with the experimental data. The reliability of the entropy determination is confirmed by a comprehensive analysis of all systematic errors. In the center of the Mott insulating cloud we obtain an entropy per atom as low as 0.77kB which is about twice as large as the entropy at the Neel transition. The corresponding temperature depends on the atom number and for small fillings reaches values on the order of the tunneling energy.

Contribution of Unresolved Point Sources to the Diffuse X-ray Background below 1 keV

description: We present here the analysis of X-rays point sources detected in several observations available in the XMM-Newton public archive. We focused, in particular, on energies below 1 keV, which are of particular relevance to the understanding of the Diffuse X-ray Background. The average field of all the exposures is 0.09 deg^-2. We reached an average flux sensitivity of 5.8x10^-16 erg s^-1 cm^-2 in the soft band (0.5-2.0 keV) and 2.5x10^-16 erg s^-1 cm^-2 in the very soft band (0.4-0.6 keV). In this paper we discuss the logN-logS results, the contribution to the integrated X-ray sky flux, and the properties of the cumulative spectrum from all sources. In particular, we found an excess flux at around 0.5 keV in the composite spectrum of faint sources. The excess seems to be a general property of all the fields observed suggesting an additional class of weak sources is contributing to the X-ray emission at these energies. Combining our results with previous investigations we have also quantified the contribution of the individual components of the diffuse X-ray Background in the 3/4 keV band.

description: Trapping and optically interfacing laser-cooled neutral atoms is an essential requirement for their use in advanced quantum technologies. Here we simultaneously realize both of these tasks with cesium atoms interacting with a multi-color evanescent field surrounding an optical nanofiber. The atoms are localized in a one-dimensional optical lattice about 200 nm above the nanofiber surface and can be efficiently interrogated with a resonant light field sent through the nanofiber. Our technique opens the route towards the direct integration of laser-cooled atomic ensembles within fiber networks, an important prerequisite for large scale quantum communication schemes. Moreover, it is ideally suited to the realization of hybrid quantum systems that combine atoms with, e.g., solid state quantum devices.
Realization of wind field reconstruction for real-time monitoring and LIDAR-assisted control

Subjects: floating offshore wind, lidar, wind turbine control

description: Presentation at the 5th International Conference on Offshore Renewable Energy Lidar-assisted control solutions have been successfully developed and applied to onshore and offshore wind turbines. Common controllers adjust the generator torque or blade pitch depending on the rotor speed measurement, only. This means they “react” to wind or wave disturbances. If a reconstructed wind field from Lidar data is available, the controller can act even before a disturbance has arrived at the turbine. This yields a more stable power output, reduced loads and increased availability. In the French-German research project VAMOS/FLOATEOLE, a nacelle-based Lidar will be installed on the FLOATGEN prototype together with the real-time Lidar data processing unit by sowento. In a first step, the uncertainty of the Lidar data will be assessed using full-system load and motion measurements, which will be compared against simulated data. Lidar-assisted control is a key concept for floating wind as it serves three objectives: It helps to reduce increased loads due to larger motion amplitudes of the platform, compared to onshore turbines. Second, it increases the knowledge about the environmental conditions like rotor-effective wind speed, wind direction and wind shear. This data is usually not available from standard sensors. If the Lidar data is available in real time, as in VAMOS/FLOATEOLE, monitoring and fault detection applications can access it to improve their reliability. Third, power performance and load levels can be continuously monitored, which is necessary for a dynamic assessment of the cumulated fatigue damage. We want to present our existing simulative results showing the benefit of Lidar-assisted wind field reconstruction. It will be shown that using that knowledge, the short-term rotor speed standard deviation above rated can be reduced by more than 60 percent. Our vision is to develop and test easily adaptable Lidar-assisted control solutions with a competitive cost to be installed on every unit of a floating wind farm.

Dynamic masses for the close PG1159 binary SDSSJ212531.92-010745.9

description: SDSSJ212531.92-010745.9 is the first known PG1159 star in a close binary with a late main sequence companion allowing a dynamical mass determination. The system shows flux variations with a peak-to-peak amplitude of about 0.7 mag and a period of about 6.96h. In August 2007, 13 spectra of SDSSJ212531.92-010745.9 covering the full orbital phase range were taken at the TWIN 3.5m telescope at the Calar Alto Observatory (Alméria, Spain). These confirm the typical PG1159 features seen in the SDSS discovery spectrum, together with the Balmer series of hydrogen in emission (plus other emission lines), interpreted as signature of the companion's irradiated side. A radial velocity curve was obtained for both components. Using co-added radial-velocity-corrected spectra, the spectral analysis of the PG1159 star is being refined. The system's lightcurve, obtained during three seasons of photometry with the Göttingen 50cm and Tübingen 80cm telescopes, was fitted with both the NIGHTFALL and PHOEBE binary simulation programs. An accurate mass determination of the PG1159 component from the radial velocity measurements requires to first derive the inclination, which requires light curve modelling and yields further constraints on radii, effective temperature and separation of the system's components. From the analysis of all data available so far, we present the possible mass range for the PG1159 component of SDSSJ212531.92-010745.9.

Spin Hall and longitudinal conductivity of a conserved spin current in two dimensional heavy-hole gases

description: The spin Hall and longitudinal conductivity of a 2D heavy-hole gas with {\it k}-cubic Rashba and Dresselhaus spin-orbit interaction is studied in the ac frequency domain. Using Kubo linear-response theory and a recently proposed definition for the (conserved) spin current operator suitable for spin-3/2 holes, it is shown that the spin conductivity tensor exhibit very distinguishable features from those obtained with the standard definition of the spin current. This is due to a significant contribution of the spin-torque term arisen from the alternative definition of spin current which strongly affects the magnitude and the sign of the dynamic spin current. In the dc (free of disorder) limit, the spin Hall conductivity for only (or dominant) {\it k}-cubic Rashba coupling is $σ^{s,z}_{xy}(0)=-9e/8π$, whereas $σ^{s,z}_{xy}(0)=-3e/8π$ for only (or dominant) {\it k}-cubic Dresselhaus coupling. Such anisotropic response is understood in terms of the absence of mapping the {\it k}-cubic Rashba $\leftrightarrow$ Dresselhaus Hamiltonians. This asymmetry is also responsible for the non-vanishing dc spin Hall conductivity ($σ^{s,z}_{xy}(0)=-6e/8π$) when the Rashba and Dresselhaus parameters have the same strength, in contrast with its corresponding case for electrons. These results are of relevance to validate the alternative definition of spin-current through measurements in the frequency domain of the spin accumulation and/or spin currents in 2D hole gases.

Discreteness of Space from the Generalized Uncertainty Principle

description: Various approaches to Quantum Gravity (such as String Theory and Doubly Special Relativity), as well as black hole physics predict a minimum measurable length, or a maximum observable momentum, and related modifications of the Heisenberg Uncertainty Principle to a so-called Generalized Uncertainty Principle (GUP). We propose a GUP consistent with String Theory, Doubly Special Relativity and black hole physics, and show that this modifies all quantum mechanical Hamiltonians. When applied to an elementary particle, it implies that the space which confines it must be quantized. This suggests that space itself is discrete, and that all measurable lengths are quantized in units of a fundamental length (which can be the Planck length). On the one hand, this signals the breakdown of the spacetime continuum picture near that scale, and on the other hand, it can predict an upper bound on the quantum gravity parameter in the GUP, from current observations. Furthermore, such fundamental discreteness of space may have observable consequences at length scales much larger than the Planck scale.

description: We discuss recent observations of high energy cosmic ray positrons and electrons in the context of hadronic interactions in supernova remnants, the suspected accelerators of galactic cosmic rays. Diffusive shock acceleration can harden the energy spectrum of secondary positrons relative to that of the primary protons (and electrons) and thus explain the rise in the positron fraction observed by PAMELA above 10 GeV. We normalize the hadronic interaction rate by holding pion decay to be responsible for the gamma-rays detected by HESS from some SNRs. By simulating the spatial and temporal distribution of SNRs in the Galaxy according to their known statistics, we are able to then fit the electron (plus positron) energy spectrum measured by Fermi. It appears that IceCube has good prospects for detecting the hadronic neutrino fluxes expected from nearby SNRs.

title: Austrian foreign policy and 20 years of EU membership: opportunities and constraints
Creators: name: Müller, Patrick

Year: 2016

description: When Austria joined the EU in 1995 it had to find its place in a substantially altered world order. Yet, rather than conceiving its membership in the EU as an opportunity to reenergize its foreign policy through Europeanization, Austria has displayed little interest in developing an active foreign policy profile within, or through, the EU. While membership in the EU meant a broadening of Austria’s foreign policy agenda – as Austria became involved in a broad range of international issues and started to participate in the multi-level negotiation process of the EU - its main contributions to European foreign poli- cy occurred in areas close to its national interest, as exemplified by its active role in the Western Balkans. Simultaneously, EU membership placed considerable constraints on Austria’s formerly independent national foreign policy, especially on Austria’s neutrality. This special issue brings together different international scholars with a longstanding expertise on different aspects of Austrian foreign policy that they will cover to take stock of the Europeanization of Austrian foreign policy two decades after it joined the EU.

description: We present a systematic study of the optical contrast of diselenide (NbSe2) and molybdenum disulphide (MoS2) flakes deposited onto Si wafers with a thermally grown SiO2 layer. We measure the optical contrast of flakes whose thickness ranges from 200 layers down to a monolayer using different illumination wavelengths in the visible spectrum. The refractive index of these thin crystals has been obtained from the measured optical contrast dependence on the flake thickness by using a simple model based on the Fresnel law. With the refractive index of these NbSe2 and MoS2 crystallites, the optical microscopy data can be quantitatively analyzed to determine the thickness of the flakes in a fast and non-destructive way.

Bistable states of quantum dot array junctions for high-density memory

description: We demonstrate that two-dimensional (2D) arrays of coupled quantum dots (QDs) with six-fold degenerate p orbitals can display bistable states, suitable for application in high-density memory device with low power consumption. Due to the inter-dot coupling of $p_x$ and $p_y$ orbitals in these QD arrays, two dimensional conduction bands can be formed in the x-y plane, while the $p_z$ orbitals remain localized in the x-y plane such that the inter-dot coupling between them can be neglected. We model such systems by taking into account the on-site repulsive interactions between electrons in $p_z$ orbitals and the coupling of the localized $p_z$ orbitals with the 2D conduction bands formed by $p_x$ and $p_y$ orbitals. The Green's function method within an extended Anderson model is used to calculate the tunneling current through the QDs. We find that bistable tunneling current can exist for such systems due to the interplay of the on-site Coulomb interactions (U) between the $p_z$ orbitals and the delocalized nature of conduction band states derived from the hybridization of $p_x$ / $p_y$ orbitals. This bistable current is not sensitive to the detailed band structure of the two dimensional band, but depends critically on the strength of $U$ and the ratio of the left and right tunneling rates. The behavior of the electrical bistability can be sustained when the 2D QD array reduces to a one-dimensional QD array, indicating the feasibility for high-density packing of these bistable nanoscale structures.

description: Bad metal properties have motivated a description of the parent iron pnictides as correlated metals on the verge of Mott localization. What has been unclear is whether interactions can push these and related compounds to the Mott insulating side of the phase diagram. Here we consider the iron oxychalcogenides La2O2Fe2O(Se,S)2, which contain an Fe square lattice with an expanded unit cell. We show theoretically that they contain enhanced correlation effects through band narrowing compared to LaOFeAs, and we provide experimental evidence that they are Mott insulators with moderate charge gaps. We also discuss the magnetic properties in terms of a Heisenberg model with frustrating J1-J2-J2' exchange interactions on a "doubled" checkerboard lattice.

UNNATURAL AMINO ACIDS AS SYNTHETIC TOOLS FOR THE PREPARATION OF COMPLEX MOLECULAR ARCHITECTURES

description: Self-assembly is the process by which an organized structure spontaneously is formed from individual components, as a result of specific, local interactions between the units. In recent years, peptide-based self-assembled structures have emerged as a powerful approach for developing soft and hybrid materials due to their biocompatibility, biodegradability and easily tuning properties of the final structure. The introduction of non-natural amino acids into a peptide backbone imparts additional features such as reduced conformational flexibility, high tendency to adopt a well-defined secondary structure and enhanced metabolic stability. My PhD thesis is focused on the synthesis of ultrashort peptides containing non-natural scaffolds which are able to self-assemble and form supramolecular structures. The thesis is divided into three chapters, each one reports a project regarding the synthesis and chemical characterization of scaffolds which can be inserted in peptide sequences and exploited for developing soft or hybrid materials by self-assembly. The first chapter concerns the supramolecular assemblies of spherical shape obtained from different peptides containing C?,?-tetrasubstituted amino acids. Firstly, the results on a pentapeptide containing norbornene amino acid is reported (work published on RSC Advances). Then, the simplification of this structure is reported until obtaining a pentapeptide containing Ala-Aib motif only. The ability of this peptide to form aggregates that can be exploited for the encapsulation of hydrophobic molecules has been studied. As a proof of concept the well-known curcumin molecule has been used. The interaction of the drug molecules with peptide aggregates has been studied using the absorption and the intrinsic fluorescence emission of curcumin. Starting from this peptide, it is also possible to develop peptide-ligands which stabilize gold nanoparticles in aqueous solution. The stability of nanoparticles has been studied using DLS and UV-vis spectroscopy. The second chapter reports on a ?2,3-diarylamino acid, developed in our group, which is non-natural analogous of the dipeptide Phe-Phe. This amino acid has been used to develop hybrid antifouling film which has been characterized using different techniques (contact angles values, QCM-D). The third chapter concerns the preparation of an original heterocyclic scaffold to be inserted into a peptide backbone and its exploitation for the formation of soft materials by the way of an ?induced assembly?. The electrospinning technique allowed the formation of electrospun nanofibers from these non-natural peptide-based small molecules and their characterization with several techniques (SEM, AFM, FT-IR, Raman) is reported.
