The influence of a combined elevation-vegetation site factor on the nature of the stable humus formed in soils derived from volcanic ash
Creators: name: Drijber, Rhae Alda
Publisher: name: University of British Columbia
Year: 2010

description: An elevational sequence of soils on the volcano Iztaccihuatl was selected to study the effect of a combined elevation-vegetation site factor on the nature of the stable humus formed in soils developed from recent volcanic ash. One sample plot was selected in each of three vegetation zones; Abies religiosa, Pinus hartwegii and Zacatonal, an alpine grassland. In Part 1, non-parametric statistics were used to evaluate several parameters measured on the Ah₁ and Ah₂ soil horizons. In Part 2, composite samples were prepared and the polymeric humic acid and fraction A were bulk isolated. The results from Part 1 indicated that the soils were at an early stage in their development. The degree of mineral weathering increased with elevation and with depth in the profile. In the surface mineral horizons humus-Al complexes were dominant with insignificant formation of "amorphous" aluminosilicate clay minerals. Horizon differences in organic matter characteristics were not apparent in the Abies religiosa and Zacatonal zones, but were present in the Pinus hartwegii zone. The humus content differed little among the three zones, although qualitative differences related to the vegetation site factor were apparent in the kinds of organic components in the fulvic acid fraction. The Ch/Cf ratio 1% was related to the regional climate. E 1%/400 HA indicated that the humic acids from the three vegetation zones were similar in maturity; hence, zonal differences in E 1%/600 HA and E₄/E₆ HA were related to the average polymer molecular weight which increased from the Abies religiosa to the Zacatonal zone. In Part 2, elemental and infrared analysis failed to detect any zonal differences in the humic acid and fraction A. However, the data supported the rapid formation of a high molecular weight, highly aliphatic humic acid fraction rich in nitrogen. Four major phenolic acids of lignin origin were identified in the humic acid and fraction A hydrolysates -protocatechuic acid, p-hydroxybenzoic acid, vanillic acid and syringic acid - which established a lignin-derived component of the polymeric humus fractions. The source of vegetation for humus formation could be clearly distinguished from the ratios of the major phenolic acids identified.

description: Nuclear fusion is, in a sense, the opposite of nuclear fission. Fission, which is a mature technology, produces energy through the splitting of heavy atoms like uranium in controlled chain reactions. Unfortunately, the by-products of fission are highly radioactive and long lasting. On the other hand, fusion is the process by which the nuclei of two light atoms such as hydrogen are fused together to form a heavier (helium) nucleus, with energy produced as a by-product.
Although controlled fusion is extremely technologically challenging, a fusion-power reactor would offer significant advantages over existing energy sources.
This thesis is devoted to the control of tokamaks, magnetic confinement devices constructed in the shape of a torus (or doughnut). Tokamaks are the most promising of several proposed magnetic confinement devices.
The need to improve the performance of modern tokamak operations has led to a further development of the plasma shape and position control systems. In particular, extremely elongated plasmas, with high vertical-instability growth rate, are envisaged to reach the required performance for ignition. This request for better performance from the experimentalists’ side has motivated the development of the new vertical-stabilization (VS) system at the JET tokamak, which has been proposed within the Plasma Control Upgrade project.
This thesis presents the activity carried out to increase the capability of the VS system and to understand the operational limits in order to assess what can be done to improve the overall performance with the existing hardware and control system so as to minimize the impact on JET operation.
The first objective of this work is the analysis of the new diagnostic system and the influence of the mechanical structure on the magnetic measurements used as diagnostics by the VS controller; the main focus is on the influence on the controller performance in the presence of large perturbations. The second objective is to design a new controlled variable to increase the performance of the VS system. The third objective is to provide an equivalent model of an ELM (Edge Localized Mode), in terms of internal plasma profile parameters via best fit of the vertical velocity estimation. The last objective is to obtain a reliable and accurate model of the overall system, based on the new platform MARTe, developed at JET and useful also for
other devices.

Το βασικό ερευνητικό ερώτημα είναι αφενός το πώς ανταποκρίνονται οι έξυπνες πόλεις σήμερα στη σύγχρονη πρόκληση για τη γενικότερη βελτίωση της ποιότητας ζωής στις πόλεις αλλά και πώς οι ίδιοι οι πολίτες διαδραματίζουν ενεργό ρόλο σε αυτή τη διαδικασία.
Με επίκεντρο το δημόσιο χώρο, η εργασία αναπτύσσει μια μεθοδολογία που βασίζεται στη χρήση αστικών τεχνολογιών και στην οπτικοποίηση δεδομένων για τη συμμετοχική επανάκτηση των υπαρχόντων δημόσιων ανοιχτών χώρων της πόλης όσον αφορά την αστική ευημερία. Μέσω της μεθοδολογίας προτείνεται ότι μια συνεχής κυκλική διαδικασία μπορεί να ενισχύσει την αναγέννηση των αστικών χώρων, εν μέρει σε επίπεδο γειτονιάς και συνολικά σε επίπεδο πόλης, και να βοηθήσει τους δημόσιους ανοιχτούς χώρους να διαμορφωθούν ως πιο βιώσιμα αστικά περιβάλλοντα με τον ενεργό ρόλο των πολιτών.

description: The aim of the dissertation is to investigate the relationship of the contemporary city with urban prosperity, the achievement of physical and mental well-being of its inhabitants. The key research question is on the one hand how smart cities today are responding to the contemporary challenge of improving the overall quality of life in cities but also how citizens themselves are playing an active role in this process. Focusing on public space, research develops a methodology based on the use of urban technologies and data visualization for the participatory regain of existing public open spaces in the city in terms of urban prosperity. Through the proposed methodology it is expected that a cyclical process can continuously empower the urban spaces regeneration, partially at neighborhood level and overall at the city level, and help public open spaces be shaped as more sustainable urban environments with the active role of citizens.

description: Binary evolution is influenced by dynamical scattering with other stars in dense environments. Heggie's law states that, due to their environments, hard binaries (whose orbital energy surpasses the typical energy of single stars) tend to harden (increase their orbital energy), while soft binaries typically soften. Here, we show that Heggie's law sometimes needs to be revised, by accounting for an external potential, for example, for binaries in nuclear stellar discs or AGN discs, that are affected by the central massive black hole, or binary planetesimals in proto-planetary discs, affected by the host star. We find that in such environments, where the Hill radius is finite, binary-single scattering can have different outcomes. In particular, a three-body encounter could be cut short due to stars being ejected beyond the Hill radius, thereby ceasing to participate in further close interactions. This leads to a systematic difference in the energy changes brought about by the encounter, and in particular slows binary hardening, and even causes some hard binaries to soften, on average, rather than harden. We use our previously derived analytical, statistical solution to the bound chaotic three-body problem to quantitatively characterise the revision of the hardening-softening phase transition and evolution of binaries. We also provide an analytical calculation of the mean hardening rate of binaries in any environment (also reproducing the results of detailed N-body simulations). We show that the latter exhibits a non-trivial dependence on the Hill radius induced by the environment.

description: We study the growth of cosmological perturbations in the model of Lorentz-violating massive gravity. The Friedman equation in this model acquires an unconventional term due to the Lorentz-breaking condensates which has the equation of state w = -1 / (3 gamma) with gamma being a free parameter taking values outside of the range [0,1/3]. Apart from the standard contributions, the perturbations above the Friedmann background contain an extra piece which is proportional to an arbitrary function theta(x) of the space coordinates. This function appears as an integration constant and corresponds to a non-propagating scalar mode which may, however, become dynamical with the account of the higher-derivative corrections. For -1 < gamma < 0 and gamma = 1 the ``anomalous'' perturbations grow slower than the standard ones and thus the model is compatible with observations. Whether the model is experimentally acceptable at other values of γdepends on the value of the function theta(x) at the beginning of the radiation-dominated epoch.

A review of the one-parameter division undistortion model
Creators: name: Erdnüß, B.
Publisher: name: International Society for Photogrammetry and Remote Sensing (ISPRS)
Year: 2021

description: The one-parameter division undistortion model by (Lenz, 1987) and (Fitzgibbon, 2001) is a simple radial distortion model with beneficial algebraic properties that allows to reason about some problems analytically that can only be handled numerically in other distortion models. One property of this distortion model is that straight lines in the undistorted image correspond to circles in the distorted image. These circles are fully described by their center point, as the radius can be calculated from the position of the center and the distortion parameter only. This publication collects the properties of this distortion model from several sources and reviews them. Moreover, we show in this publication that the space of this center is projectively isomorphic to the dual space of the undistorted image plane, i.e. its line space. Therefore, projective invariant measurements on the undistorted lines are possible by the according measurements on the centers of the distorted circles. As an example of application, we use this to find the metric distance of two parallel straight rails with known track gauge in a single uncalibrated camera image with significant radial distortion.
Liquid elasticity length, universal dynamic crossovers and glass transition

description: We discuss two main universal dynamic crossovers in a liquid that correspond to relaxation times of 1 ps and 10^{-7}--10^{-6} s. We introduce the concept of liquid elasticity length $d_{\rm el}$. At room temperature, $d_{\rm el}$ is several Åin water and increases to 0.01 mm in honey and 1 mm in tar. We discuss that on temperature decrease, $d_{\rm el}=d_{\rm m}$ and $d_{\rm el}=L$ correspond to the two dynamic crossovers, where $d_{\rm m}$ is the medium-range order and L is system size. The second crossover defines all kinetic aspects of the glass transition whereas ``thermodynamic'' glass transition is realized in the limit of infinite system size only. One prediction of this picture is the increase of viscosity with the size of macroscopic system, which we verify by measuring the viscosity of honey.

description: Using an extended chromomagnetic model, we perform a systematic study of the masses of the doubly heavy tetraquarks. We find that the ground states of the doubly heavy tetraquarks are dominated by color-triplet $\ket{(qq)^{\bar{3}_{c}}(\bar{Q}\bar{Q})^{3_{c}}}$ configuration, which is opposite to that of the fully heavy tetraquarks. The combined results suggest that the color-triplet configuration becomes more important when the mass difference between the quarks and antiquarks increases. We find three stable states which lie below the thresholds of two pseudoscalar mesons. They are the $IJ^{P}=01^{+}$ $nn\bar{b}\bar{b}$ tetraquark, the $IJ^{P}=00^{+}$ $nn\bar{c}\bar{b}$ tetraquark and the $J^{P}=1^{+}$ $ns\bar{b}\bar{b}$ tetraquark.

description: We have performed a thorough study of the meson-meson S-waves with isospin (I) 0 and 1/2, up to sqrt(s) ~ 2 GeV. This is the first study that includes 13 channels that have their threshold below that energy. All the resonances below 2 GeV, namely the f_0(600) or sigma, f_0(980), f_0(1370), f_0(1500), f_0(1710) and f_0(1790) for I=0, and the K*_0(800) or kappa, K*_0(1430) and K*_0(1950) for I=1/2, are generated. We can then extract a clear picture of the spectroscopy, finding that the f_0(1710), together with an important contribution to the f_0(1500), are glueballs. Another pole, which corresponds mainly to the f_0(1370), is a pure octet I=0 state, and does not mix with the glueball.

IAM_COMPACT_D2.1_Stakeholder_Engagement_Plan
Creators: name: Heussaff, Conall
Publisher: name: Zenodo
Year: 2022

description: Ensuring the policy-relevant output is a fundamental aim of IAM COMPACT. This document outlines a stakeholder engagement plan that can facilitate knowledge sharing and collaboration between modellers and stakeholders to achieve these aims. The key objectives of stakeholder engagement in the project are to ensure policy relevance, share knowledge and enhance trust between modellers and stakeholders, and provide direct inputs from stakeholders to make modelling socially and politically realistic.

The core of the stakeholder engagement plan will revolve around the policy response mechanism, a structured format for engagement between project partners and stakeholders. The stakeholders for IAM COMPACT will be selected from a stakeholder pool, managed by project partner Bruegel, building upon Bruegel’s contacts from previous similar projects. A variety of engagement techniques will be employed, including but not limited to bilateral interviews, workshops, and public events.

Bruegel will lead the operation of the policy response mechanism, in collaboration with all project partners. The process will involve two co-creative cycles, each comprising: selection of stakeholders from the project database, co-creation with stakeholders of a policy-relevant research agenda for two modelling iterations, refinement and updating of the research questions after the first iteration, discussion and feedback on modelling results, and finally the dissemination of the policy recommendations based on the research outputs.

IAM_COMPACT_D4.3_Broad_Scenario_Logic
Creators: name: Korsbakken, Jan Ivar

Publisher: name: Zenodo
Year: 2023

description: This report provides the first iteration of a broad scenario logic for the IAM COMPACT project. A broad scenario logic is a narrative and/or a set of assumptions and specifications that serve as a common basis for a number of different modelling exercises that in turn address a collection of different research questions. It serves as a default background, which is then complemented and potentially overridden by more specific and detailed scenario protocols for each modelling exercise. In IAM COMPACT the set of research questions is highly diverse, without a common thread across the whole project. This report, therefore, does not contain a background narrative but focuses on harmonising assumptions and input data that are likely to be relatively independent of specific research questions and can serve as common defaults across most modelling exercises. It also briefly outlines how input data will be shared and gives guidelines for model output formats. Because the definition of the concrete modelling approaches to be used to address the individual research questions follow the submission of this deliverable, this report is only a first iteration and maps out questions that need to be settled through more detailed discussions with modelling teams at the beginning of the first IAM COMPACT modelling cycle. A more complete update will be given in D4.4, at the transition from the first to the second modelling cycle (July 2024)

description: Collective excitations spectrum of Dirac electrons in mono and bilayer graphene in the presence of a uniform magnetic field is investigated. Analytical results for inter-Landau band plasmon spectrum within the self-consistent-field approach are obtained. SdH type oscillations that are a monotonic function of the magnetic field are observed in the plasmon spectrum of both mono- and bi-layer graphene systems. The results presented are also compared with those obtained in conventional 2DEG. The chiral nature of the quasiparticles in mono and bilayer graphene system results in the observation of $π$ and $2π$ Berry's phase in the SdH- type oscillations in the plasmon spectrum.

description: We revisit the problem of building the Lagrangian of a large class of metric theories that respect spatial covariance, which propagate at most two degrees of freedom and in particular no scalar mode. The Lagrangians are polynomials built of the spatially covariant geometric quantities. By expanding the Lagrangian around a cosmological background and focusing on the scalar modes only, we find the conditions for the coefficients of the monomials in order to eliminate the scalar mode at the linear order in perturbations. We find the conditions up to $d=4$ with $d$ the total number of derivatives in the monomials and determine the explicit Lagrangians for the cases of $d=2$, $d=3$ as well as the combination of $d=2$ and $d=3$. We also expand the Lagrangian of $d=2$ to the cubic order in perturbations, and find additional conditions for the coefficients such that the scalar mode is eliminated up to the cubic order. This perturbative analysis can be performed order by order, and one expects to determine the final Lagrangian at some finite order such that the scalar mode is fully eliminated. Our analysis provides an alternative and complimentary approach to building spatially covariant gravity with only tensorial degrees of freedom. The resulting theories can be used as alternatives to the general relativity to describe the tensorial gravitational waves in a cosmological setting.

Modelling survival rates in bilateral breast cancer
Creators: name: Dunn, Lindsay Allison
Publisher: name: University of British Columbia
Year: 2010

description: This study involves modelling hazard rates for failure from two related causes, unilateral and bilateral breast cancer in women. Of interest is the incorporation of information from cases who survived the first cause of death into the hazard for the second cause of death. Proportional hazards regression models and survival plots are used to investigate this question for breast cancer patients seen by the A. Maxwell Evans Clinic in Vancouver; a large data set was provided by the Cancer Control Agency of B.C. It is discovered that controls and cases differ in covariates important to the first cause of death. As a result, hazard functions for the two causes of death are not directly comparable. A multistate model using hazards specific to particular transitions towards death is recommended for further analysis of the survival relationships.
Effect of aspect ratio on cross-flow turbine performance

description: Cross-flow turbines convert kinetic power in wind or water currents to mechanical power. Unlike axial-flow turbines, the influence of geometric parameters on turbine performance is not well-understood, in part because there are neither generalized analytical formulations nor inexpensive, accurate numerical models that describe their fluid dynamics. Here, we experimentally investigate the effect of aspect ratio - the ratio of the blade span to rotor diameter - on the performance of a straight-bladed cross-flow turbine in a water channel. To isolate the effect of aspect ratio, all other non-dimensional parameters are held constant, including the relative confinement, Froude number, and Reynolds number. The coefficient of performance is found to be invariant for the range of aspect ratios tested (0.95 - 1.63), which we ascribe to minimal blade-support interactions for this turbine design. Finally, a subset of experiments is repeated without controlling for the Froude number and the coefficient of performance is found to increase, a consequence of Froude number variation that could mistakenly be ascribed to aspect ratio. This highlights the importance of rigorous experimental design when exploring the effect of geometric parameters on cross-flow turbine performance.

description: Light-front holographic QCD provides a successful first approximation to hadron spectroscopy in the chiral limit of $(3+1)$-dim light-front QCD, where a holographic Schrödinger-like equation, with an emerging confining scale, $κ$, governs confinement in the transverse direction. In its supersymmetric formulation, light-front holography predicts that each baryon has two superpartners: a meson and a tetraquark, with their degenerate masses being generated by the same scale, $κ$. In nature, this mass degeneracy is lifted by chiral symmetry breaking and longitudinal confinement. In this paper, we show that the latter can be successfully captured by the 't Hooft equation of $(1+1)$-dim, large $N_c$, QCD. Together, the holographic Schrödinger equation and the 't Hooft equation, provide a good global description of the data across the full hadron spectrum with a universal $κ$.

description: In this paper, the nonlinear dimension reduction algorithm Uniform Manifold Approximation and Projection (UMAP) is investigated to visualize information contained in high dimensional feature representations of Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) data. Based on polarimetric parameters, target decomposition methods and interferometric coherences a wide range of features is extracted that spans the high dimensional feature space. UMAP is applied to determine a representation of the data in 2D and 3D euclidean space, preserving local and global structures of the data and still suited for classification. The performance of UMAP in terms of generating expressive visualizations is evaluated on PolInSAR data acquired by the F-SAR sensor and compared to that of Principal Component Analysis (PCA), Laplacian Eigenmaps (LE) and t-distributed Stochastic Neighbor embedding (t-SNE). For this purpose, a visual analysis of 2D embeddings is performed. In addition, a quantitative analysis is provided for evaluating the preservation of information in low dimensional representations with respect to separability of different land cover classes. The results show that UMAP exceeds the capability of PCA and LE in these regards and is competitive with t-SNE.

Политика инновационного развития региона, исходя из условий неравномерного развития его территории, должна предполагать генерацию инноваций в инновационно - активных территориях и их трансфер на территории с малой инновационной активностью. Для повышения инновационного потенциала необходимо в первую очередь генерировать инновационные технологии и перестраивать все производство непосредственно под данные технологии. В настоящее время инновационные технологии адаптируют под производственные возможности, которые зачастую ограничены. В итоге затраты на инновации становятся неэффективными. Высшие учебные заведения оказывают значительное влияние на развитие региона. Прямое влияние идет за счет подготовки высокоспециализированных кадров, таким образом, реализуется основная задача вуза как учебного заведения, а также за счет инновационных разработок, которые необходимы для устойчивого развития промышленности в регионе.

description: Современный мир отличает углубление процессов международной экономической интеграции, в условиях которой приобретает актуальность проблема поддержания необходимого уровня конкурентоспособности. В статье представлены результаты сравнительного анализа влияния инновационной составляющей экономики в обеспечении конкурентоспособности развитых и развивающихся стран. Теоретической базой исследования выступает трехуровневая модель М. Портера, согласно которой факторы конкурентоспособности имеют разное значение для стран, находящихся на разных уровнях экономического развития. В качестве основной проблематики исследования был выдвинут вопрос о роли инноваций в поддержании национальной конкурентоспособности развитых и развивающихся стран. Для проверки поставленной гипотезы были использованы методы эконометрического моделирования. В ходе исследования было показано, что влияние инновационных факторов на формирование конкурентоспособности изменяется для стран, находящихся на разных стадиях экономического развития.

description: The periodic standing wave method studies circular orbits of compact objects coupled to helically symmetric standing wave gravitational fields. From this solution an approximation is extracted for the strong field, slowly inspiralling motion of black holes and binary stars. Previous work on this model has dealt with nonlinear scalar models, and with linearized general relativity. Here we present the results of the method for the post-Minkowski (PM) approximation to general relativity, the first step beyond linearized gravity. We compute the PM approximation in two ways: first, via the standard approach of computing linearized gravitational fields and constructing from them quadratic driving sources for second-order fields, and second, by solving the second-order equations as an ``exact'' nonlinear system. The results of these computations have two distinct applications: (i) The computational infrastructure for the ``exact'' PM solution will be directly applicable to full general relativity. (ii) The results will allow us to begin supplying initial data to collaborators running general relativistic evolution codes.

description: We compute the dispersion relations for scalar, vector and tensor modes of a viscous relativistic fluid, linearized around an equilibrium solution, for a divergence type theory (which, in the linearized theory, includes Israel-Stewart and anisotropic hydrodynamics as particular cases) and contrast them to the corresponding results derived from kinetic theory under the relaxation time approximation, and from causal first order theories. We conclude that all approaches give similar dynamics for the scalar and vector modes, while the particular divergence type theory presented here also contains propagating damped tensor waves, in agreement with kinetic theory. Non hydrodynamic tensor modes are also a feature of holographic fluids. These results support the application of hydrodynamics in problems involving the interaction between fluids and gravitational waves.

description: In 1981, Foias, Guillopé and Temam proved a priori estimates for arbitrary-order space derivatives of solutions to the Navier-Stokes equation. Such bounds are instructive in the numerical investigation of intermittency often observed in simulations, e.g., numerical study of vorticity moments by Donzis et al. (2013) revealed depletion of nonlinearity that may be responsible for smoothness of solutions to the Navier-Stokes equation. We employ an original method to derive analogous estimates for space derivatives of three-dimensional space-periodic weak solutions to the evolutionary equations of diffusive magnetohydrodynamics. Construction relies on space analyticity of the solutions at almost all times. An auxiliary problem is introduced, and a Sobolev norm of its solutions bounds from below the size in $C^3$ of the region of space analyticity of the solutions to the original problem. We recover the exponents obtained earlier for the hydrodynamic problem. The same approach is also followed here to derive and prove similar a priori bounds for arbitrary-order space derivatives of the first-order time derivative of the weak MHD solutions. This paper is dedicated to Professor Uriel Frisch on the occasion of his 80th anniversary as a sign of appreciation of the Scientist and the Teacher.

Interplay of size and Landau quantizations in the de Haas-van Alphen oscillations of metallic nanowires

description: We examine the interplay between size quantization and Landau quantization in the De Haas-Van Alphen oscillations of clean, metallic nanowires in a longitudinal magnetic field for `hard' boundary conditions, i.e. those of an infinite round well, as opposed to the `soft' parabolically confined boundary conditions previously treated in Alexandrov and Kabanov (Phys. Rev. Lett. {\bf 95}, 076601 (2005) (AK)). We find that there exist {\em two} fundamental frequencies as opposed to the one found in bulk systems and the three frequencies found by AK with soft boundary counditions. In addition, we find that the additional `magic resonances' of AK may be also observed in the infinite well case, though they are now damped. We also compare the numerically generated energy spectrum of the infinite well potential with that of our analytic approximation, and compare calculations of the oscillatory portions of the thermodynamic quantities for both models.
description: Title changed, paper streamlined on suggestion of referrees, typos corrected, numerical error in figs 2 and 3 corrected and final result simplified -- two not three frequencies (as in the previous version) are observed. Abstract altered accordingly. Submitted to Physical Review B

description: Менеджмент в наши дни остро нуждается в переосмыслении. Его теория и методология уже не просто не соответствуют, но всё чаще противоречат сложившейся практике управления коллективной деятельностью. Однообразие теоретических моделей, выводов и рекомендаций не согласовывается с многообразием форм и методов социально-экономической активности людей. Общество пережило не одну научно-техническую революцию, которые радикально изменили технологии производства, роль и место человека в производственном процессе. Однако, это почти никак не отразилось на методах и формах организации управления, не привело к появлению принципиально новых знаний в теории менеджмента. В связи с этим основное внимание в статье обращено к исследованию аксиоматики классической теории управления как основы для формирования в дальнейшем новой парадигмы управления современными организациями, представляющими из себя сложные социально-экономические системы, на принципах управления контекстом организации. В статье, не претендуя на полноту, представлена достаточно стройная система, включающая десять аксиом классической теории менеджмента. На основе данной аксиоматической системы можно выстраивать дальнейший анализ слабых мест и направлений развития теории и методологии организации управления в современных социально-экономических системах. Аксиоматика практически однозначно определяет те направления, по которым может развиваться научная управленческая мысль.
Extracting signatures of quantum criticality in the finite-temperature behavior of many-body systems

description: We face the problem of detecting and featuring footprints of quantum criticality in the finite-temperature behavior of quantum many-body systems. Our strategy is that of comparing the phase diagram of a system displaying a T=0 quantum phase transition with that of its classical limit, in order to single out the genuinely quantum effects. To this aim, we consider the one-dimensional Ising model in a transverse field: while the quantum S=1/2 Ising chain is exactly solvable and extensively studied, results for the classical limit (infinite S) of such model are lacking, and we supply them here. They are obtained numerically, via the Transfer-matrix method, and their asymptotic low-temperature behavior is also derived analytically by self-consistent spin-wave theory. We draw the classical phase-diagram according to the same procedure followed in the quantum analysis, and the two phase diagrams are found unexpectedly similar: Three regimes are detected also in the classical case, each characterized by a functional dependence of the correlation length on temperature and field analogous to that of the quantum model. What discriminates the classical from the quantum case are the different values of the exponents entering such dependencies, a consequence of the different nature of zero-temperature quantum fluctuations with respect to thermal ones.
