description: The famous three-body problem can be traced back to Newton in 1687, but quite few families of periodic orbits were found in 300 years thereafter. In this paper, we propose an effective approach and roadmap to numerically gain planar periodic orbits of three-body systems with arbitrary masses by means of machine learning based on an artificial neural network (ANN) model. Given any a known periodic orbit as a starting point, this approach can provide more and more periodic orbits (of the same family name) with variable masses, while the mass domain having periodic orbits becomes larger and larger, and the ANN model becomes wiser and wiser. Finally we have an ANN model trained by means of all obtained periodic orbits of the same family, which provides a convenient way to give accurate enough predictions of periodic orbits with arbitrary masses for physicists and astronomers. It suggests that the high-performance computer and artificial intelligence (including machine learning) should be the key to gain periodic orbits of the famous three-body problem.

THE INFLUENCE OF GOVERNMENT FISCAL POLICIES ON CORPORATE BUDGETING: HOW PUBLIC SECTOR BUDGETING TRENDS AFFECT PRIVATE SECTOR FINANCIAL PLANNING
Creators: name: Mbonigaba Celestin
Publisher: name: Zenodo
Year: 2017

description: This study explores the impact of government fiscal policies on corporate budgeting, focusing on the period from 2012 to 2016. The need for this study arises from the volatile fiscal landscape that many countries experienced during these years, characterized by fluctuating tax rates, changes in public expenditure, and increasing fiscal deficits. These fiscal changes created an uncertain environment for businesses, necessitating adaptive corporate financial strategies. The research objectives were to assess the influence of corporate tax rate changes, government expenditure fluctuations, and fiscal policy uncertainty on private sector budgeting. A descriptive and explanatory methodology was employed, utilizing secondary data from global economic records and financial reports. Key findings include a negative correlation between rising tax rates and capital investment, with investment declining by 0.6% for every 1% increase in tax rates. Additionally, an increase in government expenditure was linked to more proactive corporate budgeting, as companies anticipated higher demand driven by public sector activities. The study also found that fiscal unpredictability led to a heightened adoption of risk management strategies by businesses. In conclusion, fiscal stability is crucial for fostering business confidence and encouraging long-term investments. It is recommended that governments aim for more predictable fiscal policies and that companies strengthen their financial adaptability to mitigate risks. The overall correlation coefficient between fiscal policy changes and corporate budgeting was -0.45, indicating a significant inverse relationship between fiscal unpredictability and corporate investment decisions.

description: Collective behaviour of final-state hadrons, and multiparton interactions are studied in high-multiplicity $ep$ scattering at a centre-of-mass energy $\sqrt{s}=318$ GeV with the ZEUS detector at HERA. Two- and four-particle azimuthal correlations, as well as multiplicity, transverse momentum, and pseudorapidity distributions for charged-particle multiplicities $N_{\textrm ch} \geq 20$ are measured. The dependence of two-particle correlations on the virtuality of the exchanged photon shows a clear transition from photoproduction to neutral current deep inelastic scattering. For the multiplicities studied, neither the measurements in photoproduction processes nor those in neutral current deep inelastic scattering indicate significant collective behaviour of the kind observed in high-multiplicity hadronic collisions at RHIC and the LHC. Comparisons of PYTHIA predictions with the measurements in photoproduction strongly indicate the presence of multiparton interactions from hadronic fluctuations of the exchanged photon.

description: Climate transition spans all aspects of society, including the Digital Humanities. Researchers and research development professionals will need to play their part. However, as yet UK funders do not provide resources detailing how researchers can make changes to their  research practices in support of environmental and ecological sustainability.

Funders justifiably set expectations around research practice, including impacts on the environment.  UK Research and Innovation (UKRI) have published a sustainability strategy and is a signatory of a cross-sector environmental sustainability concordat, and in December 2024, the AHRC Research Funding Guide was updated to include a statement on environmental responsibility.

Aimed primarily at Digital Humanities researchers and research offices, this short guide explores the policy resources underpinning the AHRC statement. It offers a series of interpretations of existing guidance on research practice and points to advice on how to operationalise sustainable practice in Digital Humanities research. Our interpretations draw on the Digital Humanities Climate Coalition Toolkit, an extensive and evolving resource that provides guidance on making research practices more environmentally responsible.

description: In this work, perovskite solar cells (PSCs) with different transport layers were fabricated to understand the hysteresis phenomenon under a series of scan rates. The experimental results show that the hysteresis phenomenon would be affected by the dielectric constant of transport layers and scan rate significantly. To explain this, a modified Poisson and drift-diffusion solver coupled with a fully time-dependent ion migration model is developed to analyze how the ion migration affects the performance and hysteresis of PSCs. The simulation model was optimized for carrier transportation of organic materials, which can simulate the organic transport layer correctly without using heavy doping in simulating the organic transport layer. The modeling results show that the most crucial factor in the hysteresis behavior is the built-in electric field of the perovskite. The non-linear hysteresis curves are demonstrated under different scan rates, and the mechanism of the hysteresis behavior is explained. The findings reveal why the change in hysteresis degree with scan rate is Gaussian shaped rather than monotonic. Additionally, other factors contributing to the degree of hysteresis are determined to be the degree of degradation in the perovskite material, the quality of the perovskite crystal, and the materials of the transport layer, which corresponds to the total ion density, carrier lifetime of perovskite, and the dielectric constant of the transport layer, respectively. Finally, it was found that the dielectric constant of the transport layer is a key factor affecting hysteresis in perovskite solar cells; a lower dielectric constant corresponds to a higher electric field of the transport layer. Hence, if the electric field of the perovskite material is small, the degree of hysteresis is small and vice versa.

description: GitHub has become the central online platform for much of open source, hosting most open source code repositories. With this popularity, the public digital traces of GitHub are now a valuable means to study teamwork and collaboration. In many ways, however, GitHub is a convenience sample, and may not be representative of open source development off the platform. Here we develop a novel, extensive sample of public open source project repositories outside of centralized platforms. We characterized these projects along a number of dimensions, and compare to a time-matched sample of corresponding GitHub projects. Our sample projects tend to have more collaborators, are maintained for longer periods, and tend to be more focused on academic and scientific problems.

Radiative decay of an emitter due to non-Markovian interactions with dissipating matter

description: It is known that the more tractable Markovian models of coupling suited for weak interactions may overestimate the Rabi frequency notably when applied to the strong-coupling regime. Here, a more significant consequence of the non-Markovian interaction between a photon emitter and dissipating matter such as resonant plasmonic nanoparticles is described. A large increase of radiative decay and a diminished non-radiative loss is shown, which unravels the origin of unexpected large enhancements of surface-enhanced-Raman-spectroscopy (SERS), as well as the anomalous enhancements of emission due to extremely small fully absorbing metal nanoparticles less than 10 nm in dimensions. We construct the mixture of pure states of the coupled emitter-nanoparticle system, unlike conventional methods that rely on the orthogonal modes of the nanoparticle alone.

Serial correlation of withdrawal properties from axially-loaded self-tapping screws
Creators: name: Brandner, Reinhard

Publisher: name: The University of British Columbia
Year: 2015

description: Previous investigations outline the applicability of a two-level hierarchical stochastic material model combined with equicorrelation for the description of timber strength and elasticity, by explicit differentiation in variation within and between timber elements. Consequently, as far as withdrawal of primary axially-loaded self-tapping screws is concerned, the load bearing capacity of screw groups in laminated timber products depends on their positioning relative to the product layup. We analyse the first time the applicability of a two-level hierarchical model on withdrawal strength, stiffness properties and density. By testing a saturated data set, the hypothesis of equicorrelated withdrawal properties could not be rejected. Test setup, examination and accompanied epistemic uncertainties in analysing the stiffness properties are seen as general reason for their relatively high variation and consequently low correlation, whereas the high equicorrelation of withdrawal strength is explained by the homogeneous test material. However, in reality screw groups are influenced by unavoidable flaws which provoke higher variation and lower correlation. In view of previous investigations on timber strengths, an equicorrelation for withdrawal strength in the range of 0.40 to 0.50 (0.60) appears more reasonable.

description: Thermodynamics of Bardeen AdS black holes has attracted a great deal of attentions due to its intrinsic complications and rich phase structures. However, the entropy and thermodynamic volume are incorrect in some literatures. In this paper we revisit the thermodynamics of Bardeen AdS black holes and provide the correct entropy and thermodynamic volume. Furthermore, thermodynamic geometries are a powerful tool to probe the microstructure of black holes. Based on the Hessian matrix of black hole mass, we introduce a thermodynamic metric and give its scalar curvature in Weinhold's geometry. The conformal relation between Weinhold's geometry and Ruppeiner's geometry will be changed due to the specific first law of thermodynamics for regular black holes like the Bardeen AdS black hole. We also investigate the critical behaviour of phase transitions in an extended phase space, and find that the critical behaviour of the Bardeen AdS black hole coincides with that of liquid-gas systems. In particular, based on the Weinhold geometry we unveil a repulsive interaction in the microstructure of the Bardeen AdS black hole under its small volume state, while it is known that only attractive interaction exists in the microstructure of the van der Waals fluid.

description: Data representation techniques have made a substantial contribution to advancing data processing and machine learning (ML). Improving predictive power was the focus of previous representation techniques, which unfortunately perform rather poorly on the interpretability in terms of extracting underlying insights of the data. Recently, the Kolmogorov model (KM) was studied, which is an interpretable and predictable representation approach to learning the underlying probabilistic structure of a set of random variables. The existing KM learning algorithms using semi-definite relaxation with randomization (SDRwR) or discrete monotonic optimization (DMO) have, however, limited utility to big data applications because they do not scale well computationally. In this paper, we propose a computationally scalable KM learning algorithm, based on the regularized dual optimization combined with enhanced gradient descent (GD) method. To make our method more scalable to large-dimensional problems, we propose two acceleration schemes, namely, the eigenvalue decomposition (EVD) elimination strategy and an approximate EVD algorithm. Furthermore, a thresholding technique by exploiting the error bound analysis and leveraging the normalized Minkowski $\ell_1$-norm, is provided for the selection of the number of iterations of the approximate EVD algorithm. When applied to big data applications, it is demonstrated that the proposed method can achieve compatible training/prediction performance with significantly reduced computational complexity; roughly two orders of magnitude improvement in terms of the time overhead, compared to the existing KM learning algorithms. Furthermore, it is shown that the accuracy of logical relation mining for interpretability by using the proposed KM learning algorithm exceeds $80\%$.

description: Achieving an accurate description of fermionic systems typically requires considerably many more orbitals than fermions. Previous resource analyses of quantum chemistry simulation often failed to exploit this low fermionic number information in the implementation of Trotter-based approaches and overestimated the quantum-computer runtime as a result. They also depended on numerical procedures that are computationally too expensive to scale up to large systems of practical interest. Here we propose techniques that solve both problems by using various factorized decompositions of the electronic structure Hamiltonian. We showcase our techniques for the uniform electron gas, finding substantial (over 100x) improvements in Trotter error for low-filling fraction and pushing to much higher numbers of orbitals than is possible with existing methods. Finally, we calculate the T-count to perform phase-estimation on Jellium. In the low-filling regime, we observe improvements in gate complexity of over 10x compared to the best Trotter-based approach reported to date. We also report gate counts competitive with qubitization-based approaches for Wigner-Seitz values of physical interest.

description: We study the effect of probabilistic distortions to the local majority rules used in the Galam model of opinion dynamics and bottom-up hierarchical voting. A different probability for a flip against the local majority within the discussion group is associated with each ratio of majority / minority. The cases of groups of sizes 3 and 5 are investigated in detail. For hierarchical voting, the local flip corresponds to a `faithless elector', a representative who decides to vote against the choice of their electing group. Depending on the flip probabilities, the model exhibits a rich variety of patterns for the dynamics, which include novel features in the topology of the landscape. In particular, for size 5, we uncover for the first time an interplay between five fixed points, which split into either three attractors and two tipping points or two attractors and three tipping points, depending on the flip probabilities. Larger groups are also analysed. These features were absent in the former versions of the Galam model, which has at maximum three fixed points for any group size. The results shed a new light on a series of social phenomena triggered by one single individual who acts against the local majority.

description: Ce papier est une recherche consacrée à l’étude exploratoire, théorique sur la proposition d’une méthodologie d’évaluation d’un service d’audit interne à travers le cas de la SOTELMA. L’audit interne est un ensemble de processus mis en œuvre au sein d’une organisation. L’évaluation d’un service d’audit interne revient ainsi à apprécier comment ces processus sont mis en œuvre conformément aux normes d’audit. On distingue généralement trois processus à auditer au niveau Service Audit et Contrôle (SAC) de la de la SOTELMA, à savoir : le processus support relatif aux règles et aux procédures du service d’audit et la gestion des ressources ; le processus produit en rapport avec la conduite des missions d’audit à travers la planification, la réalisation des missions et le suivi des recommandations ; le processus client en relation avec les communications du service d’audit au demandeurs (clients) à savoir le management et les audités. Les résultats de l’étude intègrent le fait que les auditeurs internes font partie du cadre de pilotage. Ainsi, ils ont la possibilité d'effectuer des évaluations, permanentes ou ponctuelles, sur les autres éléments du contrôle interne de la SOTELMA. Par conséquent, l'audit interne est un élément du système de contrôle interne, et sa finalité est de s'assurer que toutes les opérations de l'entreprise sont maîtrisées et que la SOTELMA est gérée de manière efficace et transparente. L'objectif ultime de notre recherche est de mettre en place une méthodologie d’évaluation du Service Audit et Contrôle (SAC) de la SOTELMA afin de mettre en exergue son importance comme outil de gestion de l’ensemble de la SOTELMA.

description: Many scenarios of physics beyond the standard model predict new light, weakly coupled degrees of freedom, populated in the early universe and remaining as cosmic relics today. Due to their high abundances, these relics can significantly affect the evolution of the universe. For instance, massless relics produce a shift $ΔN_{\rm eff}$ to the cosmic expectation of the effective number of active neutrinos. Massive relics, on the other hand, additionally become part of the cosmological dark matter in the later universe, though their light nature allows them to freely stream out of potential wells. This produces novel signatures in the large-scale structure (LSS) of the universe, suppressing matter fluctuations at small scales. We present the first general search for such light (but massive) relics (LiMRs) with cosmic microwave background (CMB) and LSS data, scanning the 2D parameter space of their masses $m_X$ and temperatures $T_X^{(0)}$ today. In the conservative minimum-temperature ($T_X^{(0)}=0.91$ K) scenario, we rule out Weyl (and higher-spin) fermions -- such as the gravitino -- with $m_X\geq 2.26$ eV at 95% C.L., and set analogous limits of $m_X\leq 11.2, 1.06, 1.56$ eV for scalar, vector, and Dirac-fermion relics. This is the first search for LiMRs with joint CMB, weak-lensing, and full-shape galaxy data; we demonstrate that weak-lensing data is critical for breaking parameter degeneracies, while full-shape information presents a significant boost in constraining power relative to analyses with only baryon acoustic oscillation parameters. Under the combined strength of these datasets, our constraints are the tightest and most comprehensive to date.

description: p-tert-Butyphenol (PTBP) is a phenolic monomer used in the synthesis of numerous industrially useful chemicals. The current research work aimed to evaluate the effect of the biofield energy treatment on the isotopic abundance ratios of PM+1/PM and PM+2/PM in PTBP using gas chromatography - mass spectrometry (GC-MS). The sample, PTBP was distributed into two parts - one part was designated as control PTBP and another part was considered as biofield energy treated PTBP. The biofield energy treatment was achieved through unique biofield energy transmission process by Mr. Trivedi (also known as The Trivedi Effect®). T1, T2, T3, and T4 were indicated to the different time interval analysis of the biofield treated PTBP. The GC-MS spectra of the both control and biofield treated PTBP showed the presence of molecular ion peak [M+] at m/z 150 (calculated 150.10 for C10H14O) along with eight major fragmented peaks at m/z 135, 107, 95, 91, 77, 65, 41, and 39, which might be due to C10H15+, C7H7O+ or C8H11+, C6H7O+, C7H7+, C6H5+, C5H5+, C3H5+, and C3H3• •+ ions, respectively. The relative intensities of the parent molecule and other fragmented ions of the biofield treated PTBP were altered as compared to the control PTBP. The percentage in the isotopic abundance ratio of PM+1/PM was enhanced in the biofield treated PTBP at T2, T3 and T4 by 1.60%, 3.57%, and 120.13%, respectively while it was decreased by 4.14% in the treated sample at T1 with respect to the control PTBP. Consequently, the isotopic abundance ratio of PM+2/PM was increased in the biofield treated PTBP at T1, T3, and T4 by 1.28%, 2.56%, and 123.08%, respectively with respect to the control sample. On the other hand, it was reduced in the biofield treated sample at T2 by 1.28% as compared to the control PTBP. Concisely, 13C, 2H, and 17O contributions from (C10H14O)+ to m/z 151 and 18O contribution from (C10H14O)+ to m/z 152 in the biofield treated PTBP were changed with respect to the control sample and was found to have time dependent effect. The biofield energy treated PTBP might display isotope effects such as different physicochemical and thermal properties, rate of the reaction, selectivity and binding energy due to the changed isotopic abundance ratio as compared to the control sample. Biofield treated PTBP could be valuable for the designing new chemicals and pharmaceuticals through using its kinetic isotope effects.

description: We place unprecedented constraints on recoil corrections in the $β$ decay of $^8$Li, by identifying a strong correlation between them and the $^8$Li ground state quadrupole moment in large-scale ab initio calculations. The results are essential for improving the sensitivity of high-precision experiments that probe the weak interaction theory and test physics beyond the Standard Model (BSM). In addition, our calculations predict a $2^+$ state of the $α+α$ system that is energetically accessible to $β$ decay but has not been observed in the experimental $^8$Be energy spectrum, and has an important effect on the recoil corrections and $β$ decay for the $A=8$ systems. This state and an associated $0^+$ state are notoriously difficult to model due to their cluster structure and collective correlations, but become feasible for calculations in the ab initio symmetry-adapted no-core shell-model framework.

description: The objective of the current study was to evaluate the effect of biofield energy treatment on the isotopic abundance ratios of P M+1/PM, PM+2/PM, PM+3/PMand PM+4/PM in p-DCB using gas chromatography-mass spectrometry (GC-MS). The p-DCB was divided into two parts - one part was control sample, and another part was considered as the treated sample which was subjected to biofield energy treatment (The Trivedi Effect®). T1, T2, T3, and T4 were referred the biofield treated p-DCB having analyzed at different time intervals. The GC-MS analysis of both the control and biofield treated p-DCB indicated the presence of the parent molecular ion peak at m/z 146 along with four major fragmentation peaks at m/z 111, 75, 55 and 50. The relative peak intensities of the fragmented ions in the biofield treated p-DCB were notably changed as compared to the control sample with respect to the time. The isotopic abundance ratio analysis using GC-MS revealed that the isotopic abundance ratio of PM+1/PM at T1, T2, T3, and T4 (biofield energy treated p-DCB) was significantly increased by 10.87, 83.90, 225.16, and 241.15%, respectively as compared to the control sample. Consequently, the percentage change in the isotopic abundance ratio of PM+2/PM at T1, T2, and T3 (biofield energy treated p-DCB) was enhanced by 4.55, 9.49, and 1.80%, respectively as compared to the control sample. Beside these, another two isotopic molecular ion peaks at m/z 149 and 150 were found in the GS-MS spectra due to arise from the contributions of various combinations of 2H, 13C, and 37Cl. The isotopic abundance ratios of PM+3/PM in biofield energy treated sample at T1, T2, T3, and T4 was significantly increased by 15.14, 82.57, 192.43, and 218.31%, respectively as compared to the control sample. Similarly, the PM+4/PM in biofield energy treated sample at T1, T2, T3, and T4 was significantly increased by 13.80, 86.66, 186.13, and 204.29%, respectively as compared to the control sample. Overall, the isotopic abundance ratios of PM+1/PM (2H/1H or 13C/12C), PM+2/PM (37Cl/35Cl), for PM+3/PM and PM+4/PM (the probable combinations of 2H/1H, 13C/12C, and 37Cl/35Cl) were significantly enhanced in the biofield energy treated p-DCB. The biofield treated p-DCB has shown improved isotopic abundance ratios that might have altered the physicochemical properties, thermal properties and rate of reaction. Biofield treated p-DCB might be useful in pharmaceutical and chemical industries as intermediates during the manufacturing of pharmaceuticals and chemicals by monitoring the rate of chemical reaction.

description: We present the first example of $\mathcal{N}=(2,2)$ formulation for the extended higher-spin $AdS_3$ supergravity with the most general boundary conditions as an extension of the $\mathcal{N} =\,(1,1)$ work, discovered recently by us [1]. Using the method proposed by Grumiller and Riegler, we construct a consistent class of the most general boundary conditions to extend it. An important consequence of our method is that, for the loosest set of boundary conditions it ensures that their asymptotic symmetry algebras consist of two copies of the $\mathfrak{sl}(3|2)_k$. Moreover, we enjoin some certain restrictions on the gauge fields for the most general boundary conditions, leading to the supersymmetric extensions of the Brown and Henneaux boundary conditions. Based on these results, we finally find out that the asymptotic symmetry algebras are two copies of the super $\mathcal{W}_3$ algebra for $\mathcal{N} = (2,2)$ extended higher-spin supergravity theory in $AdS_3$.

description: The increasing frequency and intensity of extreme weather events caused by climate change pose significant threats toglobal ecosystems, economies, and human lives. Traditional climate monitoring and forecasting systems, while valuable, oftenstruggle to provide accurate, timely, and localized predictions. Artificial Intelligence (AI) has emerged as a powerful tool toenhance early warning systems by leveraging vast amounts of environmental, geospatial, and meteorological data. This paperexplores how AI-based early warning systems can predict climate change-related phenomena and extreme weather events moreeffectively. It examines the integration of machine learning, deep learning, and data analytics in forecasting models, highlightsreal-world applications, and discusses the role of AI in disaster preparedness and climate resilience planning. The paper alsoaddresses challenges such as data availability, model bias, and the need for transparent and ethical AI use. By improving accuracyand lead time in predictions, AI holds the potential to save lives, protect infrastructure, and inform policy decisions in an era ofaccelerating climate risks.
5D Time-Field Explanation for Fine-Structure ConstantVariations
Creators: name: MacDonald, Nathaniel
Publisher: name: Zenodo
Year: 2025

description: bstract: This paper presents a novel theoretical framework addressing the observed tension between laboratory precision measurements and astrophysical anomalies in the fine-structure constant (αα). By extending General Relativity into a five-dimensional (5D) time-field formulation, we derive a Hamiltonian structure that naturally leads to small variations in fundamental constants as a function of an extra time-like dimension. This approach provides a unified explanation for both the observed stability of αα in atomic clock experiments and the potential variation detected in quasar absorption spectra. Our model makes explicit, testable predictions, bridging the gap between quantum physics, cosmology, and gravitational theory. We discuss the implications for fundamental physics, the arrow of time, and the unification of physical laws.

Predictability as a quantum resource

description: Just recently, complementarity relations (CRs) have been derived from the basic rules of Quantum Mechanics. The complete CRs are equalities involving quantum coherence, $C$, quantum entanglement, and predictability, $P$. While the first two are already quantified in the resource theory framework, such a characterization lacks for the last. In this article, we start showing that, for a system prepared in a state $ρ$, $P$ of $ρ$, with reference to an observable $X$, is equal to $C$, with reference to observables mutually unbiased (MU) to $X$, of the state $Φ_{X}(ρ)$, which is obtained from a non-revealing von Neumann measurement (NRvNM) of $X$. We also show that $P^X(ρ)>C^{Y}(Φ_{X}(ρ))$ for observables not MU. Afterwards, we provide quantum circuits for implementing NRvNMs and use these circuits to experimentally test these (in)equalities using the IBM's quantum computers. Furthermore, we give a resource theory for predictability, identifying its free quantum states and free quantum operations and discussing some predictability monotones. Besides, after applying one of these predictability monotones to study bipartite systems, we discuss the relation among the resource theories of quantum coherence, predictability, and purity.

description: Quantum annealers manufactured by D-Wave Systems, Inc., are computational devices capable of finding high-quality solutions of NP-hard problems. In this contribution, we explore the potential and effectiveness of such quantum annealers for computing Boolean tensor networks. Tensors offer a natural way to model high-dimensional data commonplace in many scientific fields, and representing a binary tensor as a Boolean tensor network is the task of expressing a tensor containing categorical (i.e., {0, 1}) values as a product of low dimensional binary tensors. A Boolean tensor network is computed by Boolean tensor decomposition, and it is usually not exact. The aim of such decomposition is to minimize the given distance measure between the high-dimensional input tensor and the product of lower-dimensional (usually three-dimensional) tensors and matrices representing the tensor network. In this paper, we introduce and analyze three general algorithms for Boolean tensor networks: Tucker, Tensor Train, and Hierarchical Tucker networks. The computation of a Boolean tensor network is reduced to a sequence of Boolean matrix factorizations, which we show can be expressed as a quadratic unconstrained binary optimization problem suitable for solving on a quantum annealer. By using a novel method we introduce called \textit{parallel quantum annealing}, we demonstrate that tensor with up to millions of elements can be decomposed efficiently using a DWave 2000Q quantum annealer.

description: We continue our exploration of exotic, gapless lattice and continuum field theories with subsystem global symmetries. In an earlier paper, we presented free lattice models enjoying all the global symmetries (except continuous translations), dualities, and anomalies of the continuum theories. Here, we study in detail the relation between the lattice models and the corresponding continuum theories. We do that by analyzing the spectrum of the theories and several correlation functions. These lead us to uncover interesting subtleties in the way the continuum limit can be taken. In particular, in some cases, the infinite volume limit and the continuum limit do not commute. This signals a surprising UV/IR mixing, i.e., long distance sensitivity to short distance details.
