description: Conditions under which various skyrmion objects emerge in experiments on thin magnetic films remain largely unexplained. We investigate numerically centrosymmetric spin lattices in films of finite thickness with ferromagnetic exchange, magnetic anisotropy, and dipole-dipole interaction. Evolution of labyrinth domains into compact topological structures on application of the magnetic field is found to be governed by the configuration of Bloch lines inside domain walls. Depending on the combination of Bloch lines, the magnetic domains evolve into individual skyrmions, biskyrmions, or more complex topological objects. While the geometry of such objects is sensitive to the parameters, their topological charge is uniquely determined by the topological charge of Bloch lines inside the magnetic domain from which the object emerges.

description: The long range potential of helium-helium interaction, which requires accurate 'ab initio' calculation, due to the small value of the potential depth, approximately 11 K (0.091 kJ/mol) at 2.96 angstrom, will be obtained in this study by an alternative technique. This work presents a robust and consistent procedure that provides the long range potential directly from experimental data. However, it is difficult to obtain experimental data containing information regarding such a small potential depth. Thereby, sensitivity analysis will be used to circumvent this difficulty, from which viscosity data at lower temperatures (<5K) were chosen as appropriate data to be used to retrieve the potential function between 3 and 4 angstrom. The linear relationship between the potential energy function and the viscosity coefficient will be established under quantum assumptions and the Bose-Einstein statistic. The use of quantum theory is essential, since the temperatures are below 5K. The potential obtained in this study describes the viscosity with an average error of 1.68% that is less than the experimental error (5%), with the results being similar to those obtained for recent 'ab initio' potentials.

description: A study of the $η$-3N interaction in the energy region near the $η$-^3H elastic scattering threshold is presented. The calculational scheme is based on the four-body scattering formalism. A manageable form of the integral equations is achieved by using a separable ansatz for the driving two-body $ηN$- and NN-forces as well as for the subamplitudes appearing in the (1+3) and (2+2) partitions of the $η$-3N system. Results presented for the $η$-^3H scattering length point to the existence of a virtual (antibound) s-wave $η$-^3H state. As a consequence, a large enhancement of the cross section for $η$-production from three-body nuclei is predicted.

description: Violence Against Women: Entrapment, Repetition and Transformation is a reflection on my creative practice as a visual artist. The project is the culmination of five years of research into this subject, inspired by artists and theorists to examine it from a feminist point of view. It is an ongoing body of work that explores themes of power, domination, gender inequality, entrapment, repetition and transformation. These issues are still relevant today and my personal interest and experience have motivated me to use my art practice to raise awareness. Researching feminist theorists such as Amelia Valcárcel, Ana de Miguel Marcela Lagarde y Laura Segato has given me insight into the subject and allowed me to develop my artistic practice further, adding substance to my work and making my work more engaging. Philosophers Rosi Braidotti and Daisaku Ikeda have shown optimism is still possible and that we are all interconnected. They reinforce the importance of building better communities and fighting injustice against women. Key artists such as Regina José Galindo, Jenny Holzer, Susan Hiller and Lorena Wolfer have been a source of inspiration, encouraging me to explore using different media, including photography, video, installation and performance. They have also shown me ways to use specific tools in my art practice, in order to convey the message of highlighting violence against women and bring about social awareness.

description: We propose a direct, coherent coupling scheme that can create massively entangled states of Bose-Einstein condensed atoms. Our idea is based on an effective interaction between two atoms from coherent Raman processes through a (two atom) molecular intermediate state. We compare our scheme with other recent proposals for generation of massive entanglement of Bose condensed atoms. We also present explicit calculations that support detecting maximally entangled states without requiring single atom resolved measurements.

description: Population synthesis models predict that high-mass X-ray binary (HMXB) populations produced in low metallicity environments should be more X-ray luminous, a trend supported by studies of nearby galaxies. This trend may be responsible for the observed increase of the X-ray luminosity ($L_{\mathrm{X}}$) per star formation rate (SFR) with redshift due to the decrease of metallicity ($Z$) at fixed stellar mass as a function of redshift. To test this hypothesis, we use a sample of 79 $z\sim2$ star-forming galaxies with oxygen abundance measurements from the MOSDEF survey, which obtained rest-frame optical spectra for $\sim1500$ galaxies in the CANDELS fields at $1.37

description: We study the Toda field theory with finite Lie algebras using an extension of the Goulian-Li technique. In this way, we show that, after integrating over the zero mode in the correlation functions of the exponential fields, the resulting correlation function resembles that of a free theory. Furthermore, it is shown that for some ratios of the charges of the exponential fields the four-point correlation functions which contain a degenerate field satisfy the Riemann ordinary differential equation. Using this fact and the crossing symmetry, we derive a set of functional equations for the structure constants of the A_2 Toda field theory.

description: We study theoretically, via Monte Carlo simulations on lattices containing up to 1000 x 1000 spins, thermal creation of skyrmion lattices in a 2D ferromagnetic film with perpendicular magnetic anisotropy and Dzyaloshinskii-Moriya interaction. At zero temperature, skyrmions only appear in the magnetization process in the presence of static disorder. Thermal fluctuations violate conservation of the topological charge and reduce the effective magnetic anisotropy that tends to suppress skyrmions. In accordance with recent experiments, we find that elevated temperatures assist the formation of skyrmion structures. Once such a structure is formed, it can be frozen into a regular skyrmion lattice by reducing the temperature. We investigate topological properties of skyrmion structures and find the average skyrmion size. Energies of domain and skyrmion states are computed. It is shown that skyrmion lattices have lower energy than labyrinth domains within a narrow field range.

Optical response and spin relaxation in semiconductor systems under excitation with arbitrary polarization
Creators: name: Rössler, U.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The equations-of-motion for the density matrix are derived in a multiband model to describe the response of semiconductors (bulk or quantum well structures) under optical excitation with arbitrary polarization. The multiband model used, comprising the twofold conduction band and the fourfold topmost valence band (or heavy- and light-hole states), incorporates spin-splitting of the single-particle states. The interaction terms include besides the direct Coulomb coupling between carriers also the electron-hole exchange interaction, which together with the spin-splitting terms is responsible for spin relaxation. Applying the Hartree-Fock truncation scheme leads to a set of coherent semiconductor Bloch equations for the multiband case. This concept provides the theoretical frame for describing phenomena connected with optical response under excitation with arbitrary light polarization and spin relaxation: polarized optical response, polarization dynamics of VCSELs, spin relaxation, and the circular photovoltaic effect.

description: In this paper, we discuss the angular momentum distribution in the ground states of many-body systems interacting via a two-body random ensemble. Beginning with a few simple examples, a simple approach to predict P(I)'s, angular momenta I ground state (g.s.) probabilities, of a few solvable cases, such as fermions in a small single-j shell and d boson systems, is given. This method is generalized to predict P(I)'s of more complicated cases, such as even or odd number of fermions in a large single-j shell or a many-j shell, d-boson, sd-boson or sdg-boson systems, etc. By this method we are able to tell which interactions are essential to produce a sizable P(I) in a many-body system. The g.s. probability of maximum angular momentum $I_{max}$ is discussed. An argument on the microscopic foundation of our approach, and certain matrix elements which are useful to understand the observed regularities, are also given or addressed in detail. The low seniority chain of 0 g.s. by using the same set of two-body interactions is confirmed but it is noted that contribution to the total 0 g.s. probability beyond this chain may be more important for even fermions in a single-j shell. Preliminary results by taking a displaced two-body random ensemble are presented for the I g.s. probabilities.

description: In the new forest management recommendations in Finland, one cultivation alternative for Scots pine (Pinus sylvestris L.) is intensive cultivation in which the quality of a poor or mediocre pine stand is improved by carrying out an intensive, quality first thinning. This type of thinning leaves ca. 700 trees per hectare. The research conducted by Metsäteho Oy investigated how harvesting conditions and costs change when the thinning intensity is increased and intensive, quality thinning is carried out in firstthinning Scots pine stands. The study showed that the harvesting conditions in intensive, quality thinning are superior, resulting in lower harvesting costs than for normal first thinning. One item of particular note was the drop in cutting costs. Intensive, quality thinning had less of an impact on the forest haulage costs. The reduction in harvesting costs, and especially in the cutting costs, was dependent on the extent to which the average stem size of the trees to be harvested increased throughout the marked stand. When the average stem size of the trees to be harvested increased by 25%, the harvesting costs in the typical harvesting conditions of first-thinning pine stands were 15–19% lower than in normal first thinning.

description: Interaction of two skyrmions stabilized by the ferromagnetic exchange, Dzyaloshinskii-Moriya interaction (DMI), and external magnetic field has been studied numerically on a 2D lattice of size large compared to the separation, $d$, between the skyrmions. We show that two skyrmions of the same chirality (determined by the symmetry of the crystal) repel. In accordance with earlier analytical results, their long-range pair interaction falls out with the separation as $\exp(-d/δ_H)$, where $δ_H$ is the magnetic screening length, independent of the DMI. The prefactor in this expression depends on the DMI that drives the repulsion. The latter results in the spiral motion of the two skyrmions around each other, with the separation between them growing logarithmically with time. When two skyrmions of the total topological charge $Q = 2$ are pushed close to each other, the discreteness of the atomic lattice makes them collapse into one skyrmion of charge $Q = 1$ below a critical separation. Experiment is proposed that would allow one to measure the interaction between two skyrmions by holding them in positions with two magnetic tips. Our findings should be of value for designing topologically protected magnetic memory based upon skyrmions.

description: Shared opinions are an important feature in the formation of social groups. In this paper, we use the Axelrod model of cultural dissemination to represent opinion-based groups. In the Axelrod model, each agent has a set of features which each holds one of a set of nominally related traits. Survey data, for example, has a similar structure, where each participant answers each of a set of items with responses from a fixed list. We present an alternative method of displaying the Axelrod model by representing it as a bipartite graph, i.e., participants and their responses as separate nodes. This allows us to see which feature-trait combinations are selected in the final state. This visualisation is particularly useful when representing survey data as it illustrates the co-evolution of cultures and opinion-based groups in Axelrod's model of cultural diffusion. We also present a modification to the Axelrod model. A standard finding of the Axelrod model with many features is for all agents to fully agree in one cluster. We introduce an agreement threshold and allow nodes to interact only with those neighbours who are within this threshold (i.e., those with similar opinions) rather than those with any opinion. This method reliably yields a large number of clusters for small agreement thresholds and, importantly, does not limit to single cluster when the number of features grows large. This potentially provides a method for modelling opinion-based groups where as opinions are added, the number of clusters increase.

description: We consider chaotic inflation models with a pseudo-scalar field containing the general couplings to the four-form flux. The four-form mixing with the pseudo-scalar field induces a quadratic potential for inflaton while the coexisting four-form mixing with graviton generates a non-minimal gravity coupling for inflaton. The shift symmetry is respected by the derived inflaton couplings and it is broken spontaneously only by the fixed four-form flux. We discuss the success of inflationary predictions and robustness against higher order terms. Finally, the built-in reheating mechanism is also addressed.

description: The low-rank approximation is a complexity reduction technique to approximate a tensor or a matrix with a reduced rank, which has been applied to the simulation of high dimensional problems to reduce the memory required and computational cost. In this work, a dynamical low-rank approximation method is developed for the time-dependent radiation transport equation in 1-D and 2-D Cartesian geometries. Using a finite volume discretization in space and a spherical harmonics basis in angle, we construct a system that evolves on a low-rank manifold via an operator splitting approach. Numerical results on five test problems demonstrate that the low-rank solution requires less memory than solving the full rank equations with the same accuracy. It is furthermore shown that the low-rank algorithm can obtain high-fidelity results at a moderate extra cost by increasing the number of basis functions while keeping the rank fixed.

description: The Dirac equation is not semisimple. We therefore regard it as a contraction of a simpler decontracted theory. The decontracted theory is necessarily purely algebraic and non-local. In one simple model the algebra is a Clifford algebra with 6N generators. The quantum imaginary $\hbar i$ is the contraction of a dynamical variable whose back-reaction provides the Dirac mass. The simplified Dirac equation is exactly Lorentz invariant but its symmetry group is SO(3,3), a decontraction of the Poincare group, and it has a slight but fundamental non-locality beyond that of the usual Dirac equation. On operational grounds the non-locality is ~10^{-25} sec in size and the associated mass is about the Higgs mass. There is a non-standard small but unique spin-orbit coupling ~1/N, whose observation would be some evidence for the simpler theory. All the fields of the Standard Model call for similar non-local simplification.

description: We construct ten-dimensional supergravity solutions corresponding to the near horizon limit of IIB fivebranes wrapping special Lagrangian three-cycles of constant curvature. The case of branes wrapping a three-sphere provides a gravity dual of pure N=2 super-Yang-Mills theory in D=3. The non-trivial part of the solutions are seven manifolds that admit two G_2 structures each of which is covariantly constant with respect to a different connection with torsion. We derive a formula for the generalised calibration for this general class of solutions. We discuss analogous aspects of the geometry that arises when fivebranes wrap other supersymmetric cycles which lead to Spin(7) and SU(N) structures. In some cases there are two covariantly constant structures and in others one.

A straightforward a posteriori method for reduction of density-fitting error in coupled-cluster calculations
Creators: name: Lesiuk, Michał
Publisher: name: arXiv
Year: 2019
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: We present a simple method for \emph{a posteriori} removal of a significant fraction of the density-fitting error from the calculated total coupled-cluster energies. The method treats the difference between the exact and density-fitted integrals as a perturbation, and simplified response-like equations allow to calculate improved amplitudes and the corresponding energy correction. The proposed method is tested at the coupled-cluster singles and doubles level of theory for a diverse set of moderately-sized molecules. On average, error reductions by a factor of approximately ten and twenty are observed in double-zeta and triple-zeta basis sets, respectively. Similar reductions are observed in calculations of interaction energies of several model complexes. The computational cost of the procedure is small in comparison with the preceding coupled-cluster iterations. The applicability of the method is not limited to the density-fitting approximation; in principle, it can be used in conjunction with an arbitrary decomposition scheme of the electron repulsion integrals.
Dynamical mean-field approximation for pair contact process with a particle source

Publisher: name: arXiv
Year: 2002
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The one-dimensional pair contact process with a particle source is studied by using dynamical cluster mean-field approximations with sites up to $n=12$. The results obtained for different levels of approximation become convergent especially for $n \ge 6$ and allow us to derive reliable extrapolations to the limit $n \to \infty$. At the zero source limit, the critical point exhibits a discontinuity whose magnitude vanishes with $1/n$. The coherent anomaly analysis of data supports that the vanishing of order parameter and density of isolated particles has the same critical behavior. In contrast to an earlier prediction, the present approximation does not support the existence of critical behavior in the inactive phase where the frozen density of isolated particles depends on the initial state.

Here we prove that the completeness of one (any one) of the biorthogonal sequences can be omitted in the characterization.

description: Purpose: Melanocortin receptor 1 (MC1R) is overexpressed in melanoma and may be a molecular target for imaging and peptide receptor radionuclide therapy. 68Gallium (68Ga) labeling of DOTA-conjugated peptides is an established procedure in the clinic for use in positron emission tomography (PET) imaging. Aim of this study was to compare a standard labeling protocol against the 68Ga-DOTA peptide purified from the excess of unlabeled peptide. Procedures: The MC1R ligand DOTA-NAPamide was labeled with 68Ga using a standard clinical protocol. Radioactive peptide was separated from the excess of unlabeled DOTA-NAPamide by HPLC. Immediately after the incubation of peptide and 68Ga (95˚C, 15 min), the reaction was loaded on a C18 column and separated by a water/acetonitrile gradient, allowing fractionation in less than 20 minutes. Radiolabeled products were compared in biodistribution studies and PET imaging using nude mice bearing MC1R-expressing B16/F1 xenograft tumors. Results: In biodistribution studies, non-purified 68Ga-DOTA-NAPamide did not show significant uptake in the tumor at 1 h post injection (0.78% IA/g). By the additional HPLC step, the molar activity was raised around 10,000-fold by completely removing unlabeled peptide. Application of this rapid purification strategy led to a more than 8-fold increase in tumor uptake (7.0% IA/g). The addition of various amounts of unlabeled DOTA-NAPamide to the purified product led to a blocking effect and decreased specific tumor uptake, similar to the result seen with non-purified radiopeptide. PET imaging was performed using the same tracer preparations. Purified 68Ga-DOTA-NAPamide, in comparison, showed superior tumor uptake. Conclusions: We demonstrated that chromatographic separation of radiolabeled from excess unlabeled peptide is technically feasible and beneficial, even for short-lived isotopes such as 68Ga. Unlabeled peptide molecules compete with receptor binding sites in the target tissue. Purification of the radiopeptide therefore improved tumor uptake.

description: Customer satisfaction is considered a key performance indicator in business. It is a common assumption that high customer satisfaction ratings leads to repurchase of products and may also result in purchase of other products in the product line. In the present study, focus is directed at measuring customer satisfaction for wooden decking materials. Customer preferences for materials that had been subject to simulated use for two years were measured and these were compared with consumer preferences for new materials. The results indicate that customers prefer deck materials with age effects. The deck materials that had the lowest score when new, had the highest improvement of preference score after aging.

description: Public policy actions to promote innovations related business based house construction and related wood use enhancement have been wide in Finland from the mid 1990’s on but without many commercially successful innovations. This paper discusses national public policy activities in the two major clusters, real estate & construction and forest & wood product forest industry respectively. Major focus is in the challenges related to cross sectoral innovation processes that do not have position in cluster based national innovation policy favoring supply (technology) push innovation processes in financing in Finland from the mid 1990’s up to the mid 2000’s. Real estate & construction cluster enterprises tend to be risk averters in connection to new process and material solutions but have gradually from the early 2000’s started to adapt customer orientation, networking and building information models based on shared information and communication networks into their business models. Challenges to climate change mitigation and new carbon sinks have improved the potential competitive advantages of wood frame construction with respect to concrete and steel frame solutions. Innovation processes by wood product industry firms imply new orientation if they aim to BtoB demand segment outcomes. Recent Living Business program, characterized by cross cluster center of expertise networks is part of the new innovation policy approach. This try to counteract the prior low interests on cross cluster interactions, that have weakened innovation attempts to react on demand signals.

Redefining the torus: A unifying view of AGN in the infrared and sub-mm

description: The advent of high-angular resolution IR and sub-mm interferometry allows for spatially-resolved observations of the parsec-scale environment of active galactic nuclei (AGN), commonly referred to as the "torus." While molecular lines show the presence of large, massive disks, the IR observations appear to be dominated by a strong polar component that has been interpreted as a dusty wind. This paper aims at using characteristics shared by AGN in each of the wavebands and a set of simple physical principles to form a unifying view of these seemingly contradictory observations: Dusty molecular gas flows in from galactic scales of ~100 pc to the sub-parsec environment via a disk with small to moderate scale height. The hot, inner part of the disk puffs up due to IR radiation pressure and unbinds a large amount of the inflowing gas from the black hole's gravitational potential, providing the conditions to launch a wind driven by the radiation pressure from the AGN. The dusty wind feeds back mass into the galaxy at a rate of the order of ~0.1-100 $M_\odot$/yr, depending on AGN luminosity and Eddington ratio. Angle-dependent obscuration as required by AGN unification is provided by a combination of disk, wind, and wind launching region.

description: Qubit entanglement is a valuable resource for quantum information processing, where increasing its dimensionality provides a pathway towards higher capacity and increased error resilience in quantum communications, cluster computation and quantum phase measurements. Time-frequency entanglement, a continuous variable subspace, enables the high-dimensional encoding of multiple qubits per particle, bounded only by the spectral correlation bandwidth and readout timing jitter. Extending from a dimensionality of two in discrete polarization variables, here we demonstrate a hyperentangled, mode-locked, biphoton frequency comb with a time-frequency Hilbert space dimensionality of at least 648. Hong-Ou-Mandel revivals of the biphoton qubits are observed with 61 time-bin recurrences, biphoton joint spectral correlations over 19 frequency-bins, and an overall interference visibility of the high-dimensional qubits up to 98.4%. We describe the Schmidt mode decomposition analysis of the high-dimensional entanglement, in both time- and frequency-bin subspaces, not only verifying the entanglement dimensionality but also examining the time-frequency scaling. We observe a Bell violation of the high-dimensional qubits up to 18.5 standard deviations, with recurrent correlation-fringe Clauser-Horne-Shimony-Holt S-parameter up to 2.771. Our biphoton frequency comb serves as a platform for dense quantum information processing and high-dimensional quantum key distribution.

description: Due to its specific nature agriculture is exposed to a number of risks, whose emergence could lead to the losses in production as well as volatility in the business. The risks can not be completely eliminated, but they can be managed and their impacts can be minimized. Insurance could have the most important role in minimization of risk. Insurance is a form of risk management used to limit potential losses. Insurance in agriculture includes crop and fruit insurance, but also insurance of livestock, domestic and wild animals, buildings and machinery, and can be applied in greenhouses, forestry and aquaculture as well. Insurance in Serbian agriculture is undeveloped. The share of the crop insurance and the animal insurance premiums was only about 2.6% of the total non-life insurance premiums in 2011. In Serbia it has been insured only about 3% of registered farms and 8-10% of the cultivable land areas. It is common practice that governments around the world take an active role in subsidizing agricultural insurance. Since 2006 Serbian government has also introduced the subsidizing of insurance premiums in the case of animals, crops and fruits insurance (in 2006 and 2007 by 30%, while since 2007 onward by 40%). Some local governments subsidize additional 10% of premium. These incentives have not led to the increased interest of farmers to ensure their production and fixed assets. By utilization of the desk research method it has been analyzed the general situation of agricultural insurance in Serbia, together with comparative analysis of the situation in Serbia with the one in the neighboring countries and EU. On the basis of the case study method for 100 family farms belonging to the municipalities of the Belgrade city, there have been analyzed the following parameters: presence of the crop and fruit insurance at the family farms, the types of risk from which the farmers usually insure their crops and fruits, the success of getting fee for damages caused by the insured events, the reasons why insurance is not present in the larger extent in Serbian agriculture and what are the possibilities for greater use of insurance as the safest form of minimization the potential risks in agriculture. The authors have also discussed a possibility of introducing the mandatory insurance for agricultural production, as well as the participation in agricultural insurance of those stakeholders which have interest for greater use of insurance in Serbian agriculture (insurance companies, food processing companies, banks, veterinary and extension services, local government authorities etc).
