description: The sensitivity of asset fixity conclusions, input adjustment rates, and elasticities to choice of functional form is examined using a dynamic dual model of U.S. agriculture. A very general initial specification allows tests of instantaneous adjustment to be performed for every input. Test results are mixed across functional forms for all inputs except real estate, which is consistently found to be quasi-fixed. Important differences in estimated adjustment rates and elasticities are also found among the functional forms. The translog has higher likelihood support than either the generalized Leontief or normalized quadratic functional forms for this dynamic model specification and data set.

description: A growth accounting and an econometric exercise are used to provide insights into the evolution of the Taiwanese economy over the period 1966-96. The approach links the GDP function of a multiple sector neoclassical growth model to growth accounting and, subsequently to the estimation of the parameters of this function. The growth accounting results show that the contribution of total factor productivity (TFP) to growth in GDP averaged about 32 percent over the period, and this contribution increased as the economy approached its long-run equilibrium during the decade of the 1980s, with evidence of some departure during 1991-96. Growth in TFP increased output growth in industry and services while growth in skilled labor benefited all sectors. Growth in capital stock increased the growth of the industrial sector the most, followed by services, but the effect on agricultural output growth was negative. Growth in TFP and capital stock appear to have increased the capacity of the industrial and service sectors to pull resources from agriculture.

description: The problem of open-loop dynamical control of generic open quantum systems is addressed. In particular, I focus on the task of effectively switching off environmental couplings responsible for unwanted decoherence and dissipation effects. After revisiting the standard framework for dynamical decoupling via deterministic controls, I describe a different approach whereby the controller intentionally acquires a random component. An explicit error bound on worst-case performance of stochastic decoupling is presented.

description: This paper reviews recent research on the determinants of educational outcomes, and the impact of those outcomes on other socioeconomic phenomena. More specifically, it addresses three questions: 1. What school policies are most cost-effective in producing students with particular cognitive skills, such as literacy and numeracy? 2. What is the relationship between schooling, particularly cognitive skills acquired in school, and labor productivity? 3. What impact does schooling, especially cognitive skills, have on other socioeconomic outcomes? While recent research has made some progress, these are difficult questions and much more work is needed. The paper provides suggestions for future research on these questions.

description: We seek to remove foreground contaminants from 21cm intensity mapping observations. We demonstrate that a deep convolutional neural network (CNN) with a UNet architecture and three-dimensional convolutions, trained on simulated observations, can effectively separate frequency and spatial patterns of the cosmic neutral hydrogen (HI) signal from foregrounds in the presence of noise. Cleaned maps recover cosmological clustering statistics within 10% at all relevant angular scales and frequencies. This amounts to a reduction in prediction variance of over an order of magnitude on small angular scales ($\ell > 300$), and improved accuracy for small radial scales ($k_{\parallel} > 0.17\ \rm h\ Mpc^{-1})$ compared to standard Principal Component Analysis (PCA) methods. We estimate posterior confidence intervals for the network's prediction by training an ensemble of UNets. Our approach demonstrates the feasibility of analyzing 21cm intensity maps, as opposed to derived summary statistics, for upcoming radio experiments, as long as the simulated foreground model is sufficiently realistic. We provide the code used for this analysis on Github https://github.com/tlmakinen/deep21 as well as a browser-based tutorial for the experiment and UNet model via the accompanying http://bit.ly/deep21-colab Colab notebook.

description: We present a general equilibrium model with oligopsonistic market structure in one of the sectors. Buyers of inputs can set the price of inputs by being involved in rent seeking activities. The framework developed is applied to the Bulgarian economy in particular to the agro-food chain. From the application to the Bulgarian economy we find that if there are market imperfections, such as oligopsonistic behavior in the economy, there are no significant welfare gains from free trade. Significant welfare gains from trade are observed only when a competitive structure prevails. We show that eliminating this market imperfection can bring important welfare implications and an efficient reallocation of resources.

description: The population evolution of single excitation is studied in the Aubry- André- Harper (AAH) model coupled to a $d (=1,2,3)$-dimensional simple lattices bath with a focus on the effect of localization in the system and the dimensionality of bath. By performing a precise evaluation of time-independent Schrödinger equation, the reduced energy levels of the system can be determined. It is found that the reduce energy levels show significant relevance for the bath dimensions. Subsequently, the time evolution of excitation is studied in both the system and bath. It is found that excitation in the system can decay super-exponentially when $d=1$ or exponentially when $d=2,3$. Regarding the finite nature of bath, the spreading of excitation in the lattices bath is also studied. We find that, depending on the dimensions of bath and the initial state, the spreading of excitation in the bath is diffusive or behaves localization.

description: Magnetic properties of SFS and SF ramp-type junctions with $YBa_2Cu_3O_{7-δ}$ (YBCO) electrodes (S), and the itinerant ferromagnet $SrRuO_3$ (SRO - F), were investigated. We looked for a crossed Andreev reflection effect (CARE) in which an electron from one magnetic domain in F is Andreev reflected as a hole into an adjacent, oppositely polarized, domain while a pair is transmitted into S. CARE is possible in SRO since the width of its domain walls is of the order of the YBCO coherence length (2-3 nm). Our junctions behave as typical magnetic tunneling junctions, as the conductance spectra were always asymmetric, and a few showed bound state peaks at finite bias that shifted with field according to the classical Tedrow and Meservey theory. In many of our SFS junctions with a barrier thickness of 10-20 nm, a prominent zero bias conductance peak (ZBCP) has been observed. This peak was found to decrease \textit{linearly} with magnetic field, as expected for Andreev and CARE scattering. In contrast, in SF junctions, the observed ZBCP was found to decrease versus field almost \textit{exponentially}, in agreement with the Anderson-Appelbaum theory of scattering by magnetic states in F. Thus, transport in our SFS and SF junctions depends strongly on the size of the F layer. We also found that in both cases, the ZBCP height at zero field decreased with increasing magnetic order of the domains in F, in agreement with the CARE mechanism.

description: We present a numerical strategy to efficiently estimate bipartite entanglement measures, and in particular the Entanglement of Formation, for many-body quantum systems on a lattice. Our approach exploits the Tree Tensor Operator tensor network ansatz, a positive loopless representation for density matrices which, as we demonstrate, efficiently encodes information on bipartite entanglement, enabling the up-scaling of entanglement estimation. Employing this technique, we observe a finite-size scaling law for the entanglement of formation in 1D critical lattice models at finite temperature for up to 128 spins, extending to mixed states the scaling law for the entanglement entropy.

description: This paper analyzes the economy-wide gains obtainable from the allocation of surface irrigation water to its most productive use, and evaluates a decentralized mechanism for achieving this result in a spatially heterogeneous environment. The focus country for the analysis is Morocco. The analysis is based on a general equilibrium model that, in addition to the rest of the economy, captures 83 agricultural production activities, 66 of which are in seven separately identified water districts that span the entire country. The results suggest that a decentralized water trading mechanism could increase agricultural output by 8.3 percent, affect the rental rates of other agricultural inputs at the national level, including labor, and have economy-wide effects that entail modest declines in the cost of living, an increase in aggregate consumption, and expansion of international trade.

description: Spin-orbit coupled honeycomb magnets with the Kitaev interaction have received a lot of attention due to their potential of hosting exotic quantum states including quantum spin liquids. Thus far, the most studied Kitaev systems are 4d/5d-based honeycomb magnets. Recent theoretical studies predicted that 3d-based honeycomb magnets, including Na2Co2TeO6 (NCTO), could also be a potential Kitaev system. Here, we have used a combination of heat capacity, magnetization, electron spin resonance measurements alongside inelastic neutron scattering (INS) to study NCTO's quantum magnetism, and we have found a field-induced spin disordered state in an applied magnetic field range of 7.5 T < B (vertical to b-axis) < 10.5 T. The INS spectra were also simulated to tentatively extract the exchange interactions. As a 3d-magnet with a field-induced disordered state on an effective spin-1/2 honeycomb lattice, NCTO expands the Kitaev model to 3d compounds, promoting further interests on the spin-orbital effect in quantum magnets.

Mathematical modelling of liquids on surfaces

Year: 2020
Subjects: subject: 19999 Mathematical Sciences not elsewhere classified
subject: FOS: Mathematics

description: This thesis investigates the wetting behaviour of liquids on solid surfaces both in and out of equilibrium using two different general approaches from statistical mechanics. These are based on generalised lattice-gas models. Properties such as wettability and the contact angle are determined by the attraction strength parameters between the particles and with the solid surface. The wetting behaviour of liquids is characterised by the binding or interface potential, which we calculate. The two approaches used are kinetic Monte Carlo (KMC) and density functional theory (DFT). The time evolution in our KMC model involves two processes: (1) single-particle moves, which incorporates into the model particle diffusion over the surface and within the droplets, evaporation and condensation, i.e., the exchange of particles between droplets and the surrounding vapour; (2) larger-scale collective moves, which model advective hydrodynamic fluid motion, which are determined by considering the dynamics predicted by a thin-film equation. We calculate the thermodynamic quantities such as the contact angle using various methods and make a comparison between results from the different approaches. We present results for droplets joining, spreading, sliding under gravity, dewetting, the effects of evaporation, the interplay of diffusive and advective dynamics, and how all this behaviour depends on the temperature and other parameters. In addition, we consider the interfacial phase behaviour of binary liquid mixtures. We develop a DFT based method for calculating the binding potential as a function of the local adsorption of each species at the interface. This function characterises the interfacial phase behaviour of the mixture. Moreover, we show that in certain cases it can be multivalued.

We say that these manifolds are strictly causal. In particular, we prove that their fundamental groups are virtually abelian. In dimension 4, there is only one, up to a scaling factor, strictly causal manifold which is not globally hyperbolic. For a generic point of this manifold, either the past or the future is not closed and contains a lightlike straight line.

description: A wetland has no economic value in and of itself. Nor does it have a unique value, irrespective of context. Economic value is ascribed to a wetland by humans operating at a confluence of individual preferences, property rights, technological opportunities, and available resources. Such values are not generally reflected in market prices, a deficiency that can nonetheless addressed by competent economic analysis, using a variety of empirical techniques. The task is complicated by scientific information shortfalls, by ever-changing technologies and economies, and by evolving societal preferences--but it can be done. Economic valuations have been used in wetland priority rankings and in comparative investment analyses.

description: Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose condensed environment, experiments can image the system-environment interface that is central for decoherence. High precision absorption images of the condensed environment will be able to capture transient signals that show the real time build up of a mesoscopic entangled state in the environment. This is possible before decoherence sources other than the condensate itself can kick in, since qubit decoherence time-scales can be tuned from the order of nanoseconds to microseconds by choice of the excited Rydberg principal quantum number ν. Imaging the interface will allow detailed explorations of open quantum system concepts and may offer guidance for coherence protection in challenging scenarios with non-Markovian environments.

description: The problem of dipole-dipole decoherence of nuclear spins is considered for strongly entangled spin cluster. Our results show that its dynamics can be described as the decoherence due to interaction with a composite bath consisting of fully correlated and uncorrelated parts. The correlated term causes the slower decay of coherence at larger times. The decoherence rate scales up as a square root of the number of spins giving the linear scaling of the resulting error. Our theory is consistent with recent experiment reported in decoherence of correlated spin clusters.

description: The brain efficiently performs nonlinear computations through its intricate networks of spiking neurons, but how this is done remains elusive. While nonlinear computations can be implemented successfully in spiking neural networks, this requires supervised training and the resulting connectivity can be hard to interpret. In contrast, the required connectivity for any computation in the form of a linear dynamical system can be directly derived and understood with the spike coding network (SCN) framework. These networks also have biologically realistic activity patterns and are highly robust to cell death. Here we extend the SCN framework to directly implement any polynomial dynamical system, without the need for training. This results in networks requiring a mix of synapse types (fast, slow, and multiplicative), which we term multiplicative spike coding networks (mSCNs). Using mSCNs, we demonstrate how to directly derive the required connectivity for several nonlinear dynamical systems. We also show how to carry out higher-order polynomials with coupled networks that use only pair-wise multiplicative synapses, and provide expected numbers of connections for each synapse type. Overall, our work demonstrates a novel method for implementing nonlinear computations in spiking neural networks, while keeping the attractive features of standard SCNs (robustness, realistic activity patterns, and interpretable connectivity). Finally, we discuss the biological plausibility of our approach, and how the high accuracy and robustness of the approach may be of interest for neuromorphic computing.

description: Effect of uniaxial single-ion anisotropy upon magnetic properties of a mixed spin-1/2 and spin-S (S>=1) Ising model on a bathroom tile (4-8) lattice is examined within the framework of an exact star-triangle mapping transformation. The particular attention is focused on the phase diagrams established for several values of the quantum spin number S. It is shown that the mixed-spin bathroom tile lattice exhibits very similar phase boundaries as the mixed-spin honeycomb lattice whose critical points are merely slightly enhanced with respect to the former ones. The influence of uniaxial single-ion anisotropy upon the total magnetization vs. temperature dependence is particularly investigated as well.

Archival systems in the context of science
Creators: name: Rodgers, Diane Margaret
Publisher: name: University of British Columbia
Year: 2009

description: The concept of systems accounts for the organization and patterns of order that characterize the natural world. Throughout the history of science, scientific activity has been based on this concept, either implicitly under a mechanistic approach or explicitly under an holistic systems approach. Contemporary science is now based on an holistic systems viewpoint that encompasses both the natural and social worlds as objects for study. Based on this context for the systems viewpoint, the thesis addresses archival constructs, arising spontaneously as a byproduct of societal activity, as instances of systems. This is an aspect of their nature that was recognized by traditional theorists, who devised the methodology that still fundamentally guides archival practice. However, the archival field has not yet recognized the applicability and utility of formal systems notions to the work of the archivist, specifically to the tasks of arrangement, description, and appraisal. The thesis argues that appropriate handling of archival constructs requires that they be treated as systems, that the concept of systems provides a necessary framework for archival theory, and that by adopting a systems viewpoint, the archival field may regain the status of a recognized profession and join with other fields of applied science that contribute to systems research.

description: The observed pattern of neutrino mixing may be the result of a 2-3($ μ- τ$) symmetry in the leptonic sector. We consider a two Higgs doublet model with a 2-3 symmetry in the down type quark and the charged lepton sector. The breaking of the 2-3 symmetry by the strange quark mass and the muon mass leads to FCNC in the quark sector and the charged lepton sector that are suppressed by ${m_s \over m_b}$ and ${m_μ \over m_τ}$ in addition to the mass of the heavy Higgs boson of the second Higgs doublet. A Higgs boson mass of $ m_H \sim 600 - 900$ GeV can explain the deviation from standard model reported in several rare B decays. Predictions for other B decays are made and a new CP phase is predicted in $B_{s}-{\bar{B}_{s}}$ mixing. The lepton flavour violating decays $ τ\to μ\bar{l}(\bar{q}) l(q)$ are below the experimental limits. The breaking of 2-3 symmetry in the lepton sector can lead to deviations of the atmospheric neutrino mixing angle from the maximal value by $ \sim 2$ degrees.

description: We present the results of high quality long-slit spectroscopy of planetary nebulae (PNe) and HII regions in the two dwarf irregular galaxies Sextans A and B, which belong to a small group of galaxies just outside the Local Group. In Sextans A we obtained the element abundances in its only known PN and in three HII regions with the classical Te method. The oxygen abundances in these three HII regions of Sextans A are all consistent within the individual rms uncertainties, with the average 12+log(O/H) = 7.54+/-0.06. The oxygen abundance of the PN in Sextans A is, however, significantly higher: 12+$\log$(O/H) = 8.02+/-0.05. This PN is even more enriched in nitrogen and helium, suggesting a classification as a PN of Type I. In Sextans B we obtained spectra of one PN and six HII regions. Element abundances with the Te method could be derived for the PN and three of the HII regions. For two of these HII regions, which have a separation of only ~70 pc in projection, the oxygen abundances do not differ within the rms uncertainties, with a mean of 12+log(O/H) = 7.53+/-0.05. The third HII region, which is about 0.6 kpc northeast from the former two, is twice as metal-rich, with 12+log(O/H) = 7.84+/-0.05. This suggests considerable inhomogeneity in the present-day metallicity distribution in Sextans B. (Abridged)

The BRST treatment of stretched membranes

description: The BRST-invariant formulation of the bosonic stretched membrane is considered. In this formulation the stretched membrane is given as a perturbation around zero-tension membranes, where the BRST-charge decomposes as a sum of a string-like BRST-charge and a perturbation. It is proven, by means of cohomology techniques, that there exists to any order in perturbation theory a canonical transformation that reduces the full BRST-charge to the string-like one. It is also shown that one may extend the results to the quantum level yielding a nilpotent charge in 27 dimensions.

description: We study the evolution of the luminosity function (LF) of type-1 and type-2 AGN in the mid-infrared, and derive their contribution to the Cosmic InfraRed Background (CIRB) and the expected deep source counts to be observed by Spitzer at 24 micron. The sample of type-1 and type-2 AGN was selected at 15 micron (ISO) and 12 micron (IRAS), and classified on the basis of their optical spectra. Local templates of type-1 and type-2 AGN have been used to derive the intrinsic 15 micron luminosities. We adopted an evolving smooth two-power law shape of the LF, whose parameters have been derived using an un-binned maximum likelihood method. We find that the LF of type-1 AGN is compatible with a pure luminosity evolution (L(z)=L(0)(1+z)^k_L) model where k_L~2.9. A small flattening of the faint slope of the LF with increasing redshift is favoured by the data. A similar evolutionary scenario is found for the type-2 population with a rate k_L ranging from ~1.8 to 2.6, depending significantly on the adopted mid-infrared spectral energy distribution. Also for type-2 AGN a flattening of the LF with increasing redshift is suggested by the data, possibly caused by the loss of a fraction of type-2 AGN hidden within the optically classified starburst and normal galaxies. The type-1 AGN contribution to the CIRB at 15 micron is (4.2-12.1) x 10e-11 W m^-2 sr^-1, while the type-2 AGN contribution is (5.5-11.0) x 10e-11 W m^-2 sr^-1. We expect that Spitzer will observe, down to a flux limit of S_24 = 0.01 mJy, a density of ~1200 deg^-2 type-1 and ~1000 deg^-2 type-2 optically classified AGN. The derived total contribution of the AGN galaxies to the CIRB (4-10%) and Spitzer counts should be considered as lower limits, because of a possible loss of type-2 sources caused by the optical classification.

description: Dynamical phase transitions extend the notion of criticality to non-stationary settings and are characterized by sudden changes in the macroscopic properties of time-evolving quantum systems. Investigations of dynamical phase transitions combine aspects of symmetry, topology, and non-equilibrium physics, however, progress has been hindered by the notorious difficulties of predicting the time evolution of large, interacting quantum systems. Here, we tackle this outstanding problem by determining the critical times of interacting many-body systems after a quench using Loschmidt cumulants. Specifically, we investigate dynamical topological phase transitions in the interacting Kitaev chain and in the spin-1 Heisenberg chain. To this end, we map out the thermodynamic lines of complex times, where the Loschmidt amplitude vanishes, and identify the intersections with the imaginary axis, which yield the real critical times after a quench. For the Kitaev chain, we can accurately predict how the critical behavior is affected by strong interactions, which gradually shift the time at which a dynamical phase transition occurs. We also discuss the experimental perspectives of predicting the first critical time of a quantum many-body system by measuring the energy fluctuations in the initial state, and we describe the prospects of implementing our method on a near-term quantum computer with a limited number of qubits. Our work demonstrates that Loschmidt cumulants are a powerful tool to unravel the far-from-equilibrium dynamics of strongly correlated many-body systems, and our approach can immediately be applied in higher dimensions.

A Worldsheet Perspective on Heterotic T-Duality Orbifolds
Creators: name: Nibbelink, Stefan Groot
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Asymmetric heterotic orbifolds are discussed from the worldsheet perspective. Starting from Buscher's gauging of a theory of D compact bosons the duality covariant description of Tseytlin is obtained after a non-Lorentz invariant gauge fixing. A left-over of the gauge symmetry can be used to removed the doubled constant zero modes so that D physical target space coordinate remain. This can be thought of as the worldsheet realization of the strong constraint of double field theory. The extension of this description to the heterotic theory is straightforward as all results are written in terms of the invariant and the generalized metrics. An explicit method is outline how to obtain a generalized metric which is invariant under T-duality orbifold actions. It is explicitly shown how shift orbifolds lead to redefinitions of the Narain moduli. Finally, a number of higher dimensional T-folds are constructed including a novel asymmetric Z6 orbifold.

description: Optimal-control techniques and a fast-approach scheme are used to implement a collisional control phase gate in a model of cold atoms in an optical lattice, significantly reducing the gate time as compared to adiabatic evolution while maintaining high fidelity. New objective functionals are given for which optimal paths are obtained for evolution that yields a control-phase gate up to single-atom Rabi shifts. Furthermore, the fast-approach procedure is used to design a path to significantly increase the fidelity of non-adiabatic transport in a recent experiment. Also, the entanglement power of phase gates is quantified.

description: Observational data hints at a finite universe, with spherical manifolds such as the Poincare dodecahedral space tentatively providing the best fit. Simulating the physics of a model universe requires knowing the eigenmodes of the Laplace operator on the space. The present article provides explicit polynomial eigenmodes for all globally homogeneous 3-manifolds: the Poincare dodecahedral space S3/I*, the binary octahedral space S3/O*, the binary tetrahedral space S3/T*, the prism manifolds S3/D_m* and the lens spaces L(p,1).
