description: Ce mémoire de fin d’étude interroge les différences culturelles dans la maternité en se référant au maternage dans le post partum par les femmes camerounaises, soit les rites qui entourent certains soins faits au nouveau-né au sein de diverses ethnies du Cameroun. Le travail met en évidence les dilemmes de valeurs, de loyauté, de croyances et traditions à une culture d’origine par ces femmes confrontées à la culture du pays d’accueil. Cette recherche s’intéresse à visiter, dans un premier temps, les pratiques de maternage telles qu’elles sont mises en oeuvre par les femmes camerounaises dans leur pays d’origine ; il s’agit alors de voir ce qui y est fait, comment cela est-il fait et pour quelle finalité. Dans un second temps, une interview des mères camerounaises vivant en Suisse permet non seulement de « vérifier » le ressenti qui a conduit au questionnement mais aussi d’interroger ces mères sur leur vécu de la maternité en Suisse, leurs besoins et leurs attentes (...)
title: Changes in GSH and taurine levels in respose to different cage beddings and dietary patterns
Creators: name: Pehn, Kathrin
Year: 2023

description: Verschiedene Diätinterventionen haben bereits in der Vergangenheit positive Einflüsse auf oxidativen Stress gezeigt. Taurin und GSH sind ebenfalls involviert in Redox-Mechanismen. Deswegen war es von Interesse zu zeigen, ob verschiedene Diätformen Einfluss auf die Konzentrationen dieser Metabolite haben. Zuvor wurde bereits festgestellt, dass kalorienreduzierte Diäten Taurinkonzentrationen im Jejunum erhöhen, währen die GSH-Konzentrationen senken. In den Fäzes wurde ein umgekehrter Effekt festgestellt. Das führte zu der Frage, ob das Microbiom des Darms eine Rolle in diesem Zusammenhang spielen. Um dieser Frage auf den Grund zu gehen, wurde ein Experiment mit Antibiotika-behandelten Mäusen durchgeführt. Um die Mechanismen hinter diesen Veränderungen besser zu verstehen, wurden Taurintransporter und Glutathiontransferasen gemessen. Leider waren wir nicht in der Lage, einen signifikanten Einfluss verschiedener Diätformen auf die Expression der hierfür verantwortlichen Gene zu finden. Allerdings, konnten wir einen signifikanten Einfluss des Mikrobioms auf Taurin- und GSH-Konzentrationen feststellen.
description: Different diets, especially caloric restriction and fasting have shown positive influences on oxidative stress levels before. As taurine and GSH also have been shown to be involved in mechanisms of the redox-system, it was interesting to verify, if different dietary patterns might influence these levels as well. It has been shown before that caloric restriction increases taurine levels and decreases GSH levels in jejunum, whereas it shows the opposite effect in feces. Therefore, an experiment with antibiotic treated mice was performed, to see if there is any influence of microbiota on taurine and GSH-levels. To investigate into mechanisms, taurine transporter and glutathione transferases expression have been measured as well. We failed to prove any significant influences gene expressions of taurine transporters and glutathione transferases, however it was shown that microbiota has an influence on GSH and taurine levels. This proves that microbiota may have an influence on antioxidative responses.

description: In this paper we consider massless spin 2 interacting with the massive arbitrary spin fermions in d=3. First of all, we study all possible deformations for the massive fermion unfolded equations in the massless spin 2 background. We find three linearly independent solutions one of which corresponds to the standard gravitational interactions. Then for all three cases we reconstruct appropriate Lagrangian formulation.

Le genre Cheliomyrmex possède, comme les Eciton, deux castes de neutres distinctes et reconnaissables à la conformation toute différente des mandibules. La description de Mayr se rapporte au soldat, mais il existe aussi des ouvrières avec les mandibules de conformation ordinaire, c’est-à-dire aplaties, triangulaires et munies d’un bord terminal denté. Sur deux individus du Ch. Nortoni Mayr, que j'ai reçus du Mexique, l’un se trouve être un soldat, correspondant tout à fait à la description de Mayr; l’autre, au contraire, est une véritable ouvrière, et ses mandibules, conformées comme je viens de le dire, sont armées d'une grande dent à chacune des extrémités antérieure et postérieure de leur bord terminal, et en outre de cinq autres plus petites entre ces dernières. Si j’en juge d’après le seul exemplaire que j’ai sous les yeux, la taille de l’ouvrière est légèrement plus faible (6 mill.), sa tête est relativement plus petite mais de même forme, et tous ses autres caractères concordent avec ceux du soldat,

description: This paper provides an overview of the recently developed notion of viscosity solutions of path-dependent partial di erential equations. We start by a quick review of the Crandall- Ishii notion of viscosity solutions, so as to motivate the relevance of our de nition in the path-dependent case. We focus on the wellposedness theory of such equations. In partic- ular, we provide a simple presentation of the current existence and uniqueness arguments in the semilinear case. We also review the stability property of this notion of solutions, in- cluding the adaptation of the Barles-Souganidis monotonic scheme approximation method. Our results rely crucially on the theory of optimal stopping under nonlinear expectation. In the dominated case, we provide a self-contained presentation of all required results. The fully nonlinear case is more involved and is addressed in [12].

description: The Berry phase associated with energy bands in crystals can lead to quantized quantities, such as the quantization of electric dipole polarization in an insulator, known as a one-dimensional (1D) topological insulator (TI) phase. Recent theories have generalized such quantization from dipole to higher multipole moments, giving rise to the discovery of multipole TIs, which exhibit a cascade hierarchy of multipole topology at boundaries of boundaries: A quantized octupole moment in the three-dimensional (3D) bulk can induce quantized quadrupole moments on its two-dimensional (2D) surfaces, which then produce quantized dipole moments along 1D hinges. The model of 2D quadrupole TI has been realized in various classical structures, exhibiting zero-dimensional (0D) in-gap corner states. Here we report on the realization of a quantized octupole TI on the platform of a 3D acoustic metamaterial. By direct acoustic measurement, we observe 0D corner states, 1D hinge states, 2D surface states, and 3D bulk states, as a consequence of the topological hierarchy from octupole moment to quadrupole and dipole moment. The critical conditions of forming a nontrivial octupole moment are further demonstrated by comparing with another two samples possessing a trivial octupole moment. Our work thus establishes the multipole topology and its full cascade hierarchy in 3D geometries.

description: We investigate exclusive electroproduction of $π^-Δ^{++}$ within the handbag approach in which the helicity amplitudes factorize into generalized parton distributions (GPDs) and hard partonic subprocesses. We define the $p-Δ$ transversity GPDs while the helicity non-flip GPDs are taken from the literature. For the numerical estimates of observables we utilize large-$N_C$ results in order to relate a few of the $p-Δ$ GPDs to the proton-proton ones and neglect all other GPDs. In the calculation of the twist-2 and twist-3 subprocess amplitudes we take into account quark transverse momenta in combination with Sudakov suppressions. The partial cross sections for $γ^*p\to π^-Δ^{++}$ are predicted in the large-$N_C$ limit.

description: Die vorliegende Masterarbeit widmet sich drei Texten, welche alle der Dokumentarliteratur zuzuordnen sind: Martin Pollacks Der Tote im Bunker. Bericht über meinen Vater, Uwe Timms Am Beispiel meines Bruders und Sacha Battyanys Und was hat das mit mir zu tun? Ein Verbrechen im März 1945. Die Geschichte meiner Familie. Pollack, Timm und Batthyany können im Zusammenhang mit dem Nationalsozialismus als Sekundärzeugen, als nachfolgende Generation der Erlebnisgeneration, betrachtet werden. In ihren literarischen Werken setzen sich die drei genannten Schriftsteller mit ihrer eigenen Familie sowie deren Involvierung im Nationalsozialismus auseinander und stehen damit literarisch in der Tradition der Väterbücher und Familiengeschichten. Alle drei legen den Fokus auf Dokumente, Fotos, Zeug*innenaussagen, Protokolle sowie ihre eigenen Erinnerungen und versuche mithilfe dessen, ihre jeweilige Familiengeschichte zu rekonstruieren sowie Lücken, Umdeutungen und Mythen aufzudecken. Mithilfe literarischer Gestaltungsmittel soll dadurch ein realistisches Bild ihrer Familien bzw. einzelner Familienmitglieder geformt werden. Die Familie als Erinnerungsgemeinschaft stellt hierbei jenen sozialen Rahmen dar, in dem Erinnerungen an Ereignisse oder konkrete Personen ausverhandelt und ein Familiengedächtnis konstruiert wurden. Besonders die Rolle der Frauen als Erinnerungsträgerinnen im Familiengedächtnis wird im Rahmen dieser Masterarbeit kritisch hinterfragt und beleuchtet sowie deren Positionen, Zugänge und deren Schweigen und Sprechen in Bezug auf das Familiengedächtnis analysiert und miteinander verglichen. Theoretischen Erkenntnisse der Kommunikation bzw. Nicht-Kommunikation über den Nationalsozialismus werden dabei mit Pollacks, Timms und Batthyanys literarischem Werk verknüpft und der Frage nachgegangen, inwiefern sich diese theoretischen Überlegungen und Perspektiven auch in deren Rekonstruktion ihrer Familiengeschichte und ihrer literarischen Ausgestaltung von dieser zeigen.
Curriculum innovation : navigating the tensions betwen a standardised curriculum and professional autonomy

Year: 2022
Subjects: Uncategorized

description: Based on the belief that the current curriculum was not developing necessary skills or preparing pupils adequately for their next stages of education and for future employability, this research project documents the curriculum development journey of Castle School. The castle’s special story is told in an attempt to discover how teacher practitioners experience curriculum innovation against the backdrop of an externally configured National Curriculum and system of accountability. The research focuses on an innovative curriculum model, Mission Possible (MP) and adopts an ethnographic approach incorporating the use of participatory action research. This methodology was employed in order to gain an understanding of teachers’ views, perceptions and social interactions throughout the curriculum development journey. Telling the school’s story, it reveals the accounts of teachers, pupils and other members of the school community. It analyses the issues raised by teachers and explores their interpretations and explanations in relation to their own delivery of the curriculum model. It explores the tensions and risk associated with curriculum innovation, in relation to curriculum, pedagogy and assessment alongside teacher behaviours and a readiness and capacity to innovate. During this journey, the MP approach changed the interactional dimensions within the classroom, focussing on pupil collaboration. Driven by an ideology of learning and its measurement, contradictions then occurred between what was considered to be a good lesson, what good teaching looked like and how outcomes were assessed. Teachers found that learning could not be measured in the same way, as with written outcomes, resulting in assessment and curriculum coverage difficulties and a sense of uncertainty as the roles of both teacher and pupil changed. This challenged teachers’ professional identity in terms of control and performativity as their indicators of success were placed under the microscope. The researcher tells the story as a personal, autoethnographic account of a participative, action research project in order to present a personal narrative of the ethnography of the castle’s inhabitants. This allows for teachers’ views, perceptions and social interactions to be explored subjectively. It places the researcher as narrator of the castle’s unique seven year, collaborative curriculum development journey. The story of Castle School’s journey will support the curriculum development of future schools in their attempts to provide the type of education which will deliver vital tools for the future, more sophisticated skills which will prepare pupils for their next stage of education and subsequently employment.

description: Attribution methods, which employ heatmaps to identify the most influential regions of an image that impact model decisions, have gained widespread popularity as a type of explainability method. However, recent research has exposed the limited practical value of these methods, attributed in part to their narrow focus on the most prominent regions of an image -- revealing "where" the model looks, but failing to elucidate "what" the model sees in those areas. In this work, we try to fill in this gap with CRAFT -- a novel approach to identify both "what" and "where" by generating concept-based explanations. We introduce 3 new ingredients to the automatic concept extraction literature: (i) a recursive strategy to detect and decompose concepts across layers, (ii) a novel method for a more faithful estimation of concept importance using Sobol indices, and (iii) the use of implicit differentiation to unlock Concept Attribution Maps. We conduct both human and computer vision experiments to demonstrate the benefits of the proposed approach. We show that the proposed concept importance estimation technique is more faithful to the model than previous methods. When evaluating the usefulness of the method for human experimenters on a human-centered utility benchmark, we find that our approach significantly improves on two of the three test scenarios.

description: This paper summarizes the applied deep learning practices in the field of speaker recognition, both verification and identification. Speaker recognition has been a widely used field topic of speech technology. Many research works have been carried out and little progress has been achieved in the past 5-6 years. However, as deep learning techniques do advance in most machine learning fields, the former state-of-the-art methods are getting replaced by them in speaker recognition too. It seems that DL becomes the now state-of-the-art solution for both speaker verification and identification. The standard x-vectors, additional to i-vectors, are used as baseline in most of the novel works. The increasing amount of gathered data opens up the territory to DL, where they are the most effective.

description: We demonstrate fast control of the interatomic interactions in a Bose-Einstein condensate by coherently coupling two atomic states with intra- and inter-state scattering lengths of opposite signs. We measure the elastic and inelastic scattering properties of the system and find good agreement with a theoretical model describing the interactions between dressed states. In the attractive regime, we observe the formation of bright solitons formed by dressed-state atoms. Finally, we study the response of the system to an interaction quench from repulsive to attractive values, and observe how the resulting modulational instability develops into a bright soliton train.

description: In this work, we study the Gross-Pitaevskii hierarchy on general --rational and irrational-- rectangular tori of dimension two and three. This is a system of infinitely many linear partial differential equations which arises in the rigorous derivation of the nonlinear Schrödinger equation. We prove a conditional uniqueness result for the hierarchy. In two dimensions, this result allows us to obtain a rigorous derivation of the defocusing cubic nonlinear Schrödinger equation from the dynamics of many-body quantum systems. On irrational tori, this question was posed as an open problem in previous work of Kirkpatrick, Schlein, and Staffilani.

description: Ultralight dark matter is a compelling dark matter candidate. In this work, we examine the impact of quadratically-coupled ultralight dark matter on the predictions of Big Bang Nucleosynthesis. The presence of ultralight dark matter can modify the effective values of fundamental constants during Big Bang Nucleosynthesis, modifying the predicted abundances of the primordial elements such as Helium-4. We improve upon the existing literature in two ways: firstly, we take into account the thermal mass acquired by the ultralight dark matter due to its quadratic interactions with the Standard Model bath, which affects the cosmological evolution of the dark matter. Secondly, we treat the weak freeze-out using the full kinetic equations instead of using an instantaneous approximation. Both improvements were shown to impact the Helium-4 prediction in the context of universally-coupled dark matter in previous work. We extend these lessons to more general couplings. We show that with these modifications, Big Bang Nucleosynthesis provides strong constraints of ultralight dark matter with quadratic couplings to the Standard Model for a large range of masses as compared to other probes of this model, such as equivalence principle tests, atomic and nuclear clocks, as well as astrophysical and other cosmological probes.

Efficiency of Observed Information Adaptive Designs

Year: 2019
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: In this work the primary objective is to maximize the precision of the maximum likelihood estimate in a linear regression model through the efficient design of the experiment. One common measure of precision is the unconditional mean square error. Unconditional mean square error has been a primary motivator for optimal designs; commonly, defined as the design that maximizes a concave function of the expected Fisher information. The inverse of expected Fisher information is asymptotically equal to the mean square error of the maximum likelihood estimate. There is a substantial amount of existing literature that argues the mean square error conditioned on an appropriate ancillary statistic better represents the precision of the maximum likelihood estimate. Despite evidence in favor of conditioning, limited effort has been made to find designs that are optimal with respect to conditional mean square error. The inverse of observed Fisher information is a higher order approximation of the conditional mean square error than the inverse of expected Fisher information [Efron and Hinkley (1978)]. In light of this, a more relevant objective is to find designs that optimize observed Fisher information. Unlike expected Fisher information, observed Fisher information depends on the observed data and cannot be used to design an experiment completely in advance of data collection. In a sequential experiment the observed Fisher information from past observations is available to inform the design of the next observation. In this work an adaptive design that incorporates observed Fisher information is proposed for linear regression models. It is shown that the proposed design is more efficient, at the limit, than any fixed design, including the optimal design, with respect to conditional mean square error.

description: Utilizing existing transportation networks better and designing (parts of) networks involves routing decisions to minimize transportation costs and maximize consolidation effects. We study the concrete example of hinterland networks for the truck-transportation of less-than-container-load (LCL) ocean freight shipments: A set of LCL shipments is given. They have to be routed through the hinterland network to be transported to an origin port and finally to the destination port via ship. On their way, they can be consolidated in hubs to full-container-load (FCL) shipments. The overall transportation cost depends on the selection of the origin port and the routing and consolidation in the hinterland network. A problem of this type appears for the global logistics provider DB Schenker. We translate the business problem into a hub location problem, describe it mathematically, and discuss solution strategies. As a result, an integrated modeling approach has several advantages over solving a simplified version of the problem, although it requires more computational effort.

description: We study the vacuum-subtracted von Neumann entropy of a segment on a null plane. We argue that for interacting quantum field theories in more than two dimensions, this entropy has a simple expression in terms of the expectation value of the null components of the stress tensor on the null interval. More explicitly $ΔS = 2π\int d^{d-2}y \int_0^1 dx^+\, g(x^+)\, \langle T_{++}\rangle$, where $g(x^+)$ is a theory-dependent function. This function is constrained by general properties of quantum relative entropy. These constraints are enough to extend our recent free field proof of the quantum Bousso bound to the interacting case. This unusual expression for the entropy as the expectation value of an operator implies that the entropy is equal to the modular Hamiltonian, $ΔS = \langle ΔK \rangle $, where $K$ is the operator in the right hand side. We explain how this equality is compatible with a non-zero value for $ΔS$. Finally, we also compute explicitly the function $g(x^+)$ for theories that have a gravity dual.

title: Das Leben vor und nach dem Fall des Eisernen Vorhangs in einer Grenzregion - Fallbeispiel Frauenkirchen
Creators: name: Thury, Jürgen
Year: 2023

description: 1989 fiel der Eiserne Vorhang an der österreichisch-ungarischen Grenze. Zuvor bildete er nicht nur 41 Jahre die Ostgrenze des Burgenlandes, sondern teilte ganz Europa in Ost und West beziehungsweise Kapitalismus und Kommunismus. Inwiefern sich das Leben nach dem Fall des Eisernen Vorhangs in der Grenzregion liegenden Ortschaft Frauenkirchen verändert hat, wird anhand der Indikatoren Alltag, Wirtschaft, Bildung und Kultur, in der Arbeit untersucht. Neben der Analyse der Leitfadeninterviews ist die Entstehungsgeschichte des Burgenlandes, beginnend mit dem Zerfall der Doppelmonarchie bis zum noch immer andauernden Russisch-Ukrainischen-Krieg, ein wichtiger Bestandteil. Durch viele politischen Entscheidungen veränderte sich das Leben in der Grenzregion, welche natürlich auch in Frauenkirchen zu spüren waren und auch immer noch sind. Der theoretische Teil dieser Arbeit informiert über die verwendete Oral-History-Methode sowie die Erklärung des Begriffes Grenze und die Begriffsgeschichte des „Eisernen Vorhangs“.

description: We propose a class of non-integrable quantum spin chain models that exhibit quantum many-body scars even in the presence of disorder. With the use of the so-called Onsager symmetry, we construct such scarred models for arbitrary spin quantum number $ S $. There are two types of scar states, namely, coherent states associated to an Onsager-algebra element and one-magnon scar states. While both of them are highly-excited states, they have area-law entanglement and can be written as a matrix product state. Therefore, they explicitly violate the eigenstate thermalization hypothesis. We also investigate the dynamics of the fidelity and entanglement entropy for several initial states. The results clearly show that the scar states are trapped in a perfectly periodic orbit in the Hilbert subspace and never thermalize, whereas other generic states do rapidly. To our knowledge, our model is the first explicit example of disordered quantum many-body scarred model.

description: We report our comprehensive study of physical properties of a ternary intermetallic compound PrIrSi3 investigated by dc magnetic susceptibility chi(T), isothermal magnetization M(H), thermo-remnant magnetization M(t), ac magnetic susceptibility chi_ac(T), specific heat C_p(T), electrical resistivity rho(T), muon spin relaxation (muSR) and inelastic neutron scattering (INS) measurements. A magnetic phase transition is marked by a sharp anomaly at T_tr = 12.2 K in chi(T) measured at low applied fields which is also reflected in the C_p(T) data through a weak anomaly at 12 K. An irreversibility between the zero field cooled and field cooled chi(T) data below 12.2 K and a very large relaxation time of M(t) indicates the presence of ferromagnetic correlation. The magnetic part of specific heat shows a broad Schottky-type anomaly near 40~K due to the crystal electric field (CEF) effect. An extremely small value of magnetic entropy below 12 K suggests a CEF-split singlet ground state which is confirmed from our analysis of INS data. The INS spectra show two prominent inelastic excitations at 8.5 meV and 18.5 meV that could be well accounted by a CEF model. The CEF splitting energy between the ground state singlet and the first excited doublet is found to be 92 K. Our muSR data reveal a possible magnetic ordering below 30 K which is much higher than that found from the specific heat and magnetic susceptibility measurements. This could be due to the presence of short range correlations well above the long range magnetic ordering or due to the electronic changes induced by muons. The induced moment magnetism in the singlet ground state system PrIrSi3 with such a large splitting energy of 92 K is quite surprising.

description: In his classical argument, Rao derives the Riemannian distance corresponding to the Fisher metric using a mapping between the space of positive measures and Euclidean space. He obtains the Hellinger distance on the full space of measures and the Fisher distance on the subset of probability measures. In order to highlight the interplay between Fisher theory and quantum information theory, we extend this construction to the space of positive-definite Hermitian matrices using Riemannian submersions and quotient manifolds. The analog of the Hellinger distance turns out to be the Bures-Wasserstein (BW) distance, a distance measure appearing in optimal transport, quantum information, and optimisation theory. First we present an existing derivation of the Riemannian metric and geodesics associated with this distance. Subsequently, we present a novel derivation of the Riemannian distance and geodesics for this metric on the subset of trace-one matrices, analogous to the Fisher distance for probability measures.
title: Sensorische Prüfung als fachspezifische Methode in der Ernährungsbildung: ein erprobtes Unterrichtsbeispiel für die Sekundarstufe I
Creators: name: Kopecky, Claudia
Year: 2023

description: Das Ziel dieser Masterarbeit ist es, eine sensorische Prüfung in der Schule im Unterrichtsfach „Ernährung und Haushalt“ als fachspezifische Methode zu erproben und aufzuzeigen, ob sich dieses Konzept als geeignet erweist. Im ersten Teil wird auf die Theorie mit den bedeutendsten Begrifflichkeiten eingegangen und es werden auf fachwissenschaftlichem Niveau literaturbasiert die theoretischen Grundlagen dargestellt. Des Weitern geht der empirische Teil auf das Forschungsvorhaben ein und führt durch die verschiedensten Methoden eines Stationenbetriebs, die von Schüler*innen im handlungsorientierten Unterricht im Themenbereich Sensorik durchgeführt werden. Dabei werden die Schüler*innen durch sieben verschiedene Stationen in der Schulküche in mehreren Durchgängen gustatorisch geleitet, um am Ende der Verkostung ihre objektiven Eindrücke auf Fragebögen und Feedbackbögen zu vermerken. Währenddessen wurden Beobachtungen von drei Lehrkräften anhand von Beobachtungsbögen während der Verkostungen an den Stationen vorgenommen. Sowohl diese Materialien als auch die Auswertungsbögen wurden mittels Excel quantitativ und deskriptiv evaluiert. Die Analyse brachte hervor, dass die sensorische Prüfung den Schüler-Tester*innen besonders gut gefallen hat, sie diese nicht schwer fanden und sich auskannten, sowie die Verkostung gerne wiederholen würden. Besondere Bedeutung bei den Schüler*innen hatten die unterschiedlichen Herangehensweisen der Verkostungen, wie beispielsweise die Blindverkostung, die am besten ankam, oder die Verkostung verschiedener Säfte in schwarzen Gläsern und die Station, bei der mit Nasenklammer geforscht wurde. Die daraus resultierenden Forschungsergebnisse zeigen, dass eine sensorische Prüfung als fachspezifische Methode im Unterricht lehr- und abwechslungsreich für die Schüler*innen war, die sie sich in der Schule in der Ernährungsbildung, oder auch in fächerübergreifenden Lehr/Lerneinheiten, des Öfteren vorstellen können.

description: We prove the existence of minimizers of causal variational principles on second countable, locally compact Hausdorff spaces. Moreover, the corresponding Euler-Lagrange equations are derived. The method is to first prove the existence of minimizers of the causal variational principle restricted to compact subsets for a lower semi-continuous Lagrangian. Exhausting the underlying topological space by compact subsets and rescaling the corresponding minimizers, we obtain a sequence which converges vaguely to a regular Borel measure of possibly infinite total volume. It is shown that, for continuous Lagrangians of compact range, this measure solves the Euler-Lagrange equations. Furthermore, we prove that the constructed measure is a minimizer under variations of compact support. Under additional assumptions, it is proven that this measure is a minimizer under variations of finite volume. We finally extend our results to continuous Lagrangians decaying in entropy.

description: Tensor network states provide an efficient class of states that faithfully capture strongly correlated quantum models and systems in classical statistical mechanics. While tensor networks can now be seen as becoming standard tools in the description of such complex many-body systems, close to optimal variational principles based on such states are less obvious to come by. In this work, we generalize a recently proposed variational uniform matrix product state algorithm for capturing one-dimensional quantum lattices in the thermodynamic limit, to the study of regular two-dimensional tensor networks with a non-trivial unit cell. A key property of the algorithm is a computational effort that scales linearly rather than exponentially in the size of the unit cell. We demonstrate the performance of our approach on the computation of the classical partition functions of the antiferromagnetic Ising model and interacting dimers on the square lattice, as well as of a quantum doped resonating valence bond state.
