Direct numerical simulation of controlled turbulent duct flows
Creators: name: Straub, Steffen
Publisher: name: Karlsruhe
Year: 2015

description: Direkte numerische Simulationen von kontrollierten turbulenten Strömungen werden im Kanal unter Berücksichtigung der Seitenwände mit dem spectral element code Nek5000 Fischer et al. (2008) durchgeführt. Die verwendete Technik zur Strömungskontrolle ist die harmonische Oszillation der horizontalen Wände zum Zwecke der Reduktion der turbulenten Reibung. Nach bestem Wissen des Autors ist dies das erste Mal in der diese Technik zur Strömungskontrolle in in einem Kanal mit Seitenwänden numerisch untersucht wird. Verschiedene Parameter der Strömungskontrolle, und zwar die Wandgeschwindigkeitsamplitude und die kontrollierte Fläche, werden in drei unterschiedlichen Fällen getestet und ihre Ergebnisse untereinander und mit dem unkontrollierten Fall verglichen. Zwei Effekte dieser Technik zur Strömungskontrolle im rechteckigen Kanal mit Seitenwänden werden untersucht: der Effekt auf die Reibungsminderung und der Effekt auf die Sekundärströmungen, welche durch die Ecken im Kanal erzeugt werden. Zusätzlich werden einige gemittelte Statistiken ausgewertet um die Auswirkung der bewegten Wände auf die turbulente Strömung zu verstehen. Die Sekundärströmung wird verglichen zum unkontrollierten Fall stark angefacht und in Gestalt und Lage verändert. Einer der entgegengesetzt rotierenden Wirbeln in der Ecke wird verstärkt und verdrängt den anderen Wirbel näher ins Zentrum des Kanals. Im Falle von nur teilweise kontrollierten horizontalen Wänden wird ein weiteres Paar von entgegengesetzt rotierenden Wirbeln erzeugt. Das erzielte Niveau der Reibungsminderung ist verglichen zu den Ergebnissen im Kanal ohne Seitenwände sehr gering. Die einzige positive Reibungsminderung, die erreicht wird beträgt 3% in einem Fall bei dem 19% im Kanal ohne Seitenwände erreicht wird. Der Fall mit höherer Wandgeschwindigkeitsamplitude ergibt eine Reibungserhöhung von 10% und im Falle verkleinerter Fläche der Strömungskontrolle nur im Zentrum des Kanals ergibt sich eine Reibungserhöhung von 1%. Es wird gezeigt, dass diese niedrigen oder sogar negativen Werte der Reibungsminderung ein Resultat der schlechten Performance an den
Seiten des kontrollierten Gebiets sind.
First row late d-block metal pincer complexes: exploring their coordination chemistry and catalysis
Creators: name: Jinting Xu
Publisher: name: University of Leicester

Subjects: Uncategorized

description: In this thesis, the synthesis and characterisation of a series of sterically and electronically distinct N,Npy,O and N,NPy,N pincer complexes based on the late 3d metals, Zn, Co, Ni and Fe, are described; some reaction chemistry including catalysis is also disclosed. Chapter 1 presents an overview of the development and application of first row transition metal pincer complexes and their role in modern homogeneous catalysis. In Chapter 2, the synthesis of a series of novel unsymmetrical N,Npy,O and N,Npy,N (pro)ligands and their reactions with zinc(II) chloride and zinc(II) tetrafluoroborate are documented. The resulting complexes are all diamagnetic and adopt both mono- and bimetallic structures based on neutral species or cation-anion pairs; in one case a bis(pincer ligand) complex has been isolated. The amenability of selected BF4-containing zinc complexes to undergo BF4-coordination or B-F bond cleavage/hydrolysis has been demonstrated. Chapters 3 and 4 report the preparation of cobalt(II) and nickel(II) chloride/tetrafluoroborate complexes of the same (pro)ligands. A wide variety of structural types are exhibited including those based on square planar or square pyramidal geometries with steric and electronic effects proving influential. Where appropriate the paramagnetic behaviour of selected Co(II) and Ni(II) complexes has been the subject of a 1H NMR spectroscopic investigation. As with the zinc work, evidence for B-F bond hydrolysis has been noted with the N,N,N-family of pincer complexes. As an underlying theme across these three synthetic chapters, chloride exchange reactions by using CsF, AgF AgOAc and AgBF4 have been explored. Chapter 5 discusses the synthesis of one N,N,O-iron(II) chloride along with two iron(II) tetrafluoroborate complexes bearing symmetrical and unsymmetrical N,N,N-ligands. Investigations reveal that the N,N,N-complexes are suitable for use as ethylene polymerisation precatalysts when treated with either MAO or MMAO as co-catalyst. Indeed, the catalytic activity of the symmetrical N,N,N-iron(II) tetrafluoroborate catalyst has proved exceptionally high affording highly linear high molecular weight polyethylene. All experimental details for Chapters 2 – 5, including the single crystal X-ray diffraction parameters, are provided in Chapter 6.

description: The study aims to explore (1) the perspectives of health professionals on increased attendance of physical therapists (PTs) and occupational therapists (OTs) in clearly defined work assignments in two in-hospital departments and (2) the perspectives of geriatric patients on physical activity during hospitalization. A mixed-methods study using a focus group interview and a questionnaire in assessing the impact of an intervention on increased attendance of PTs and OTs in clearly defined work assignments. The patients’ perspectives on physical activity were explored in one-on-one interviews. The health professionals reported that the intervention led to a higher degree of patients’ mobilization, increased collaboration, improved the health professionals’ competencies, and provided more time for monodisciplinary assignments. The six patients stated that encouragements promoted physical activity. Increased attendance of PTs showed a positive impact on both the patients’ level of physical activity and the health professionals’ monodisciplinary assignments.

description: Foreign direct investment (FDI) in developing countries is often associated with higher economic growth due to knowledge and technology spillovers to local firms. One way how FDI speeds up growth is that it facilitates the manufacturing of more sophisticated products by local firms. So far, firm-level evidence is missing on how the presence of multinational firms affects the product sophistication of firms in a developing country. This paper aims to fill this gap. We compile an extensive firm-product-level dataset of Indian manufacturing firms which we complement with information on product sophistication and spillovers from FDI. We then explore different channels through which spillovers from multinationals to local Indian firms foster the manufacturing of sophisticated products. We find evidence that spillovers through supplier linkages strongly increase the manufacturing of sophisticated products in India.

description: In the last years several web services emerged that manage and make accessible place thesauri for the archaeologies and historical sciences. By making use of semantic technologies these applications are able to act as linked data hubs thereby making possibe the linkage of multiple datasets of varying thematic focus and of different structural properties. Another common denominator of archaeological data resources, besides geo-spatial properties, is the temporal classification of research objects. One of the applications that try to assume a role similar to that of gazetteers but for temporal concepts and cultural periods is developed in the chronOntology project. In this project, funded by the German Research Foundation, the German Archaeologial Institute (DAI) together with the i3mainz are developing a system for storing, managing, mapping and making accessible descriptions of temporal concepts. The core of this endeavor is a rich semantic modeling of various existing terminological systems for cultural periods using a data model based on the CIDOC-CRM and its extensions. The use of the rich ontological model provided by the CRM on the one hand permits representing the measurable temporal extent (with the possibility for fuzzy edges) while also making it possible to embed temporal concepts in a network of semantic relationships to other temporal concepts, connected historical regions and thematic contexts. Besides documenting the general architecture and data model of the project the paper will present possibilities of querying different heterogeneous data resources collected throughout various digitization and digging activities inside the DAI with the help of concepts defined in chronOntology. We will also point out the potential and problems of reasoning over geographically and temporally connected datasets.
Understanding when spatial transformer networks do not support invariance, and what to do about it

description: Spatial transformer networks (STNs) were designed to enable convolutional neural networks (CNNs) to learn invariance to image transformations. STNs were originally proposed to transform CNN feature maps as well as input images. This enables the use of more complex features when predicting transformation parameters. However, since STNs perform a purely spatial transformation, they do not, in the general case, have the ability to align the feature maps of a transformed image with those of its original. STNs are therefore unable to support invariance when transforming CNN feature maps. We present a simple proof for this and study the practical implications, showing that this inability is coupled with decreased classification accuracy. We therefore investigate alternative STN architectures that make use of complex features. We find that while deeper localization networks are difficult to train, localization networks that share parameters with the classification network remain stable as they grow deeper, which allows for higher classification accuracy on difficult datasets. Finally, we explore the interaction between localization network complexity and iterative image alignment.

description: The preparation stage of optical qubits is an essential task in all the experimental setups employed for the test and demonstration of Quantum Optics principles. We consider a deterministic protocol for the preparation of qubits as a superposition of vacuum and one photon number states, which has the advantage to reduce the amount of resources required via phase-sensitive measurements using a local oscillator ('dyne detection'). We investigate the performances of the protocol using different phase measurement schemes: homodyne, heterodyne, and adaptive dyne detection (involving a feedback loop). First, we define a suitable figure of merit for the prepared state and we obtain an analytical expression for that in terms of the phase measurement considered. Further, we study limitations that the phase measurement can exhibit, such as delay or limited resources in the feedback strategy. Finally, we evaluate the figure of merit of the protocol for different mode-shapes handily available in an experimental setup. We show that even in the presence of such limitations simple feedback algorithms can perform surprisingly well, outperforming the protocols when simple homodyne or heterodyne schemes are employed.

description: In a previous work, the second-named author gave a complete description of the action of automorphisms on the ordinary irreducible characters of the finite symplectic groups. We generalise this in two directions. Firstly, using work of the first-named author, we give a complete description of the action of Galois automorphisms on irreducible characters. Secondly, we extend both descriptions to cover the case of special orthogonal groups. As a consequence, we obtain explicit descriptions for the character fields of symplectic and special orthogonal groups.

description: To review the effectiveness of a tailored activity program (TAP) on neuropsychiatric symptoms (NPS), occupational performance, and quality of life among people with dementia and their caregiver burden. A literature review was completed using the following inclusion criteria: published prior to May 2021 and written in either English or Korean. The following databases were searched Embase, ProQuest, PubMed, and RISS using keywords “tailored activity program” and “dementia.” Seven studies were identified and analyzed. The effect size of the increase in quality of life was 0.79, the decrease in caregiver burden was 0.68, the decrease in NPS was 0.62, and the increase in occupational performance was 0.51. There were no publication biases. Participation in TAP resulted in decreased NPS, improved occupational performance and quality of life, and decreased caregiver burden. This study presents evidence supporting the active application of TAP for community-dwelling people with dementia.

description: We perform a comprehensive analysis of the bimagnon resonant inelastic x-ray scattering (RIXS) intensity spectra of the spatially frustrated Jx-Jy-J2 Heisenberg model on a square lattice in both the antiferromagnetic and the collinear antiferromagnetic phase. We study the model for strong frustration and significant spatial anisotropy to highlight the key signatures of RIXS spectrum splitting which may be experimentally discernible. Based on an interacting spin wave theory study within the ladder approximation Bethe-Salpeter scheme, we find the appearance of a robust two-peak structure over a wide range of the transferred momenta in both magnetically ordered phases. The unfrustrated model has a single-peak structure with a two-peak splitting originating due to spatial anisotropy and frustrated interactions. Our predicted two-peak structure from both magnetically ordered regime can be realized in iron pnictides.

description: This paper examines the holographic computation of bulk and shear viscosity ratios in strongly coupled thermal plasmas using the AdS/BCFT correspondence within Horndeski gravity. We demonstrate that this framework leads to non-zero viscosity-to-entropy ratios ($ζ/S$ and $η/S$) at low temperatures, indicating a break in conformal symmetry. At high temperatures, these ratios approach zero, recovering the expected conformal behavior of quark-gluon plasma. Our findings provide new insights into the hydrodynamic properties of strongly coupled plasmas and offer a more nuanced understanding of QCD-like theories in holographic models.

description: A typical signature of charge extraction in disordered organic systems is dispersive transport, which implies a distribution of charge carrier mobilities that negatively impact on device performance. Dispersive transport has been commonly understood to originate from a time-dependent mobility of hot charge carriers that reduces as excess energy is lost during relaxation in the density of states. In contrast, we show via photon energy, electric field and film thickness independence of carrier mobilities that the dispersive photocurrent in organic solar cells originates not from the loss of excess energy during hot carrier thermalization, but rather from the loss of carrier density to trap states during transport. Our results emphasize that further efforts should be directed to minimizing the density of trap states, rather than controlling energetic relaxation of hot carriers within the density of states.

description: We present an exact expansion of the master equation for an open quantum system. The resulting equation is time local and enables us to calculate clearly defined higher order corrections to the Born-Markov approximation. In particular, we show that non-Markovian terms are of the same order of magnitude as higher order terms in the system-bath coupling. As a result we emphasize that analyzing non-Markovian behaviour of a system implies going beyond Born approximation. Additionally, we address with this approach the initial state problem occurring in non-Markovian master equations.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The photon magnetic moment for radiation propagating in magnetized vacuum is defined as a pseudo-tensor quantity, proportional to the external electromagnetic field tensor. After expanding the eigenvalues of the polarization operator in powers of $k^2$, we obtain approximate dispersion equations (cubic in $k^2$), and analytic solutions for the photon magnetic moment, valid for low momentum and/or large magnetic field. The paramagnetic photon experiences a red shift, with opposite sign than the gravitational one, which differs for parallel and perpendicular polarizations. It is due to the drain of photon transverse momentum and energy by the external field. By defining an effective transverse momentum, the constancy of the speed of light orthogonal to the field is guaranteed. We conclude that the propagation of the photon non-parallel to the magnetic behaves as if there is a quantum compression of vacuum or warp of space-time in an amount depending on its angle with regard to the field.

description: In 1963, at the height of the Cold War, R. W. Stewart visited the Institute of Atmospheric Physics in Moscow for three months, including a side trip to a field station on the River Don. The visit followed on from discussions at scientific meetings on the topic of turbulence in fluid flows. Major theoretical advances had been made in the USSR, while Stewart's group in Canada had conducted a key observational programme in turbulent tidal currents off the coast of British Columbia. During his visit, Stewart was able to show how some Soviet observations were in accord with others after correction for instrument size and, most importantly, with Evgeny Novikov he pioneered a new approach to the theory of turbulence to allow for intermittency. His report contains observations of the style of science in the USSR in that era, as well as interesting comments on food and culture. The visit produced lasting dividends in scientific collaboration, particularly in international programmes related to climate.

description: The effective Lagrangian for Nambu-Goldstone bosons (NGBs) in systems without Lorentz invariance has a novel feature that some of the NGBs are canonically conjugate to each other, hence describing $1$ dynamical degree of freedom by two NGB fields. We develop explicit forms of their effective Lagrangian up to the quadratic order in derivatives. We clarify the counting rules of NGB degrees of freedom and completely classify possibilities of such canonically conjugate pairs based on the topology of the coset spaces. Its consequence on the dispersion relations of the NGBs is clarified. We also present simple scaling arguments to see whether interactions among NGBs are marginal or irrelevant, which justifies a lore in the literature about the possibility of symmetry breaking in $1+1$ dimensions.

description: The total infrared (IR) luminosity is very useful for estimating the star formation rate (SFR) of galaxies, but converting the IR luminosity into an SFR relies on assumptions that do not hold for all galaxies. We test the effectiveness of the IR luminosity as an SFR indicator by applying it to synthetic spectral energy distributions generated from three-dimensional hydrodynamical simulations of isolated disc galaxies and galaxy mergers. In general, the SFR inferred from the IR luminosity agrees well with the true instantaneous SFR of the simulated galaxies. However, for the major mergers in which a strong starburst is induced, the SFR inferred from the IR luminosity can overestimate the instantaneous SFR during the post-starburst phase by greater than two orders of magnitude. Even though the instantaneous SFR decreases rapidly after the starburst, the stars that were formed in the starburst remain dust-obscured and thus produce significant IR luminosity. Consequently, use of the IR luminosity as an SFR indicator may cause one to conclude that post-starburst galaxies are still star-forming, whereas in reality, star formation was recently quenched.

description: The use of herbomineral formulations in the healthcare sector has increased due to their high safety and better therapeutic action. A new proprietary herbomineral formulation was formulated with a combination of the herbal root extract ashwagandha and minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the test formulation in splenocytes. The test formulation was divided into two parts; one was the control without the Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely by seven renowned Biofield Energy Healers. The MTT assay showed that the test formulation exhibited safe concentrations up to 1.053 µg/mL with cell viability ranging from 88.19% to 110.30% in the Biofield Energy Treated sample. The Biofield Energy Healing significantly enhanced the cell viability as compared with the untreated test formulation. The expression of TNF-α was significantly inhibited by 7.23% at 1.053 µg/mL in the Biofield Energy Treated test formulation compared with the vehicle control. The level of TNF-α was significantly decreased by 3.90%, 11.74%, 3.12%, and 9.17% at 0.001053, 0.01053, 0.1053 and 1.053 µg/mL, respectively in the Biofield Energy Treated test formulation compared with the untreated test formulation. Additionally, the expression of IL-1β was significantly reduced by 28.98%, 51.23%, 53.06%, 48.98%, 55.71%, and 59.10% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, and 1.053 µg/mL, respectively in the Biofield Energy Treated test formulation compared with the vehicle control. Further, the Biofield Treated test formulation showed significant reduction of IL-1β by 35.07% (p≤0.05), 47.46% (p≤0.05), and 57.51% (p≤0.01) at 0.001053, 0.1053, and 1.053 µg/mL, respectively compared with the untreated test formulation. Similarly, the MIP-1α expression was inhibited by the Biofield Energy Treated formulation and showed immunosuppressive activity at 0.00001053, 0.0001053, 0.001053, and 0.01053 µg/mL by 19.38%, 24.97%, 31.23%, and 25.41%, respectively compared with the vehicle control group. The Biofield Treated test formulation significantly (p0.001) reduced the MIP-1α expression by 19.33%, 22.57%, and 30.50% at 0.0001053, 0.001053, and 0.01053 µg/mL, respectively compared with the untreated test formulation. Overall, The Trivedi Effect® - Biofield Energy Healing (TEBEH) significantly down-regulated the pro-inflammatory cytokines and potentiated the immunosuppressive effect of the Biofield Energy Treated test formulation, which can be better utilized for organ transplants, autoimmune diseases, inflammatory disorders, anti-aging, stress management, overall health and quality of life, etc.

description: We study the problem of solving strongly convex and smooth unconstrained optimization problems using stochastic first-order algorithms. We devise a novel algorithm, referred to as Recursive One-Over-T SGD (ROOT-SGD), based on an easily implementable, recursive averaging of past stochastic gradients. We prove that it simultaneously achieves state-of-the-art performance in both a finite-sample, nonasymptotic sense and an asymptotic sense. On the non-asymptotic side, we prove risk bounds on the last iterate of ROOT-SGD with leading-order terms that match the optimal statistical risk with a unity pre-factor, along with a higher-order term that scales at the sharp rate of $O(n^{-3/2})$ under the Lipschitz condition on the Hessian matrix. On the asymptotic side, we show that when a mild, one-point Hessian continuity condition is imposed, the rescaled last iterate of (multi-epoch) ROOT-SGD converges asymptotically to a Gaussian limit with the Cramér-Rao optimal asymptotic covariance, for a broad range of step-size choices.

description: A proprietary herbomineral formulation was formulated with four ingredients; a mixture of the minerals (zinc, magnesium, and selenium) and the herbal root extract ashwagandha. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the herbomineral formulation in splenocyte cells, which were isolated from Biofield Treated mice. The test formulation was divided into two parts. One part was denoted as the control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely from seven renowned Biofield Energy Healers. The splenocyte cells were treated with the test formulation at concentrations ranges from 0.00001053 to 10.53 µg/mL and analyzed after 48 hours of treatment by MTT assay. The cell viability data showed safe concentrations up to 1.053 µg/mL with viability ranges from 69.22% to 123.88% in the test formulation groups. The expression of TNF-α was decreased by 4.82% at 1.053 µg/mL in the Biofield Energy Treated test formulation compared with the vehicle control. The level of TNF-α was significantly decreased by 2.02%, 4.92%, and 18.78% at 0.00001053, 0.001053, and 1.053 µg/mL, respectively in the Biofield Energy Treated test formulation group as compared to the untreated test formulation. The expression of IL-1β was significantly reduced by 83.65%, 92.15%, 27.30%, and 41.88% at 0.00001053, 0.0001053, 0.001053, and 1.053 µg/mL, respectively in the Biofield Energy Treated test formulation compared with the vehicle control. The Biofield Treated test formulation showed significant reduction of IL-1β by 17.26%, 92.61% (p≤0.001), 34.62% (p≤0.05), and 16.13% at 0.00001053, 0.0001053, 0.001053, and 1.053 µg/mL, respectively compared with the untreated test formulation. Additionally, the expression of chemokine MIP-1α was significantly reduced by 17.03%, 10.99%, 22.33%, 24.21%, 21.61%, and 30.67% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, and 1.053 µg/mL, respectively in the Biofield Treated test formulation compared with the vehicle control. The MIP-1α expression was significantly reduced by 19.32% and 12.56% at 0.01053 and 0.1053 µg/mL, respectively in the Biofield Treated test formulation compared with the untreated test formulation. The overall results demonstrated that the Biofield Energy Treated test formulation significantly down-regulated the expression of TNF-α, IL-1β, and MIP-1α in the Biofield Treated mice splenocyte cells compared to the untreated test formulation. These data suggest that the Biofield Treated test formulation can be used for autoimmune and inflammatory diseases, stress management and anti-aging by improving overall health.

description: We extend the holographic construction from AdS3 to higher dimensions. In particular, we show that the Bekenstein-Hawking entropy of codimension-two surfaces in the bulk with planar symmetry can be evaluated in terms of the 'differential entropy' in the boundary theory. The differential entropy is a certain quantity constructed from the entanglement entropies associated with a family of regions covering a Cauchy surface in the boundary geometry. We demonstrate that a similar construction based on causal holographic information fails in higher dimensions, as it typically yields divergent results. We also show that our construction extends to holographic backgrounds other than AdS spacetime and can accommodate Lovelock theories of higher curvature gravity.

description: A holographic superconductor is constructed in the background of a massive gravity theory. In the normal state without condensation, the conductivity exhibits a Drude peak that approaches a delta function in the massless gravity limit as studied by David Vegh. In the superconducting state, besides the infinite DC conductivity, the AC conductivity has Drude behavior at low frequency followed by a power law-fall. These results are in agreement with that found earlier by Horowitz and Santos, who studied a holographic superconductor with an implicit periodic potential beyond the probe limit. The results also agree with measurements on some cuprates.

description: Surface floating microplastic material was collected in the Ligurian Sea during specific campaigns of the citizen science association Expedition MED. 52 samples were collected between Toulon, Calvi and Genova at an average speed of 2.5 knots during 60 min each with a Manta trawl net lined with 0.333 mm mesh. Samples were transferred to the collaborating scientific institutes. Microplastic was enumerated and measured by imaging techniques and sorted out. It was further characterized using spectroscopy or thermal analysis in order to classify it into different families of plastics as polyolefins, polystyrenics, polyesters, polyamides and others. Volunteers were involved in assisting sampling operations and were supervised closely. This interactive science program allows comforting the study on the long term. A more collaborative governance of the marine environment by citizens is another benefit of this approach.

description: We consider pure SU(N) gauge theories defined on an orbifold lattice, analogous to the S^1/Z_2 gauge theory orbifolds of the continuum, which according to the perturbative analysis do not have a Higgs phase. Non-perturbatively the conclusion for N even is the opposite, namely that spontaneous symmetry breaking does take place and some of the gauge bosons become massive. We interpret this new, non-perturbative phenomenon both mathematically and physically.

description: This paper presents a hybrid approach between scale-space theory and deep learning, where a deep learning architecture is constructed by coupling parameterized scale-space operations in cascade. By sharing the learnt parameters between multiple scale channels, and by using the transformation properties of the scale-space primitives under scaling transformations, the resulting network becomes provably scale covariant. By in addition performing max pooling over the multiple scale channels, a resulting network architecture for image classification also becomes provably scale invariant. We investigate the performance of such networks on the MNISTLargeScale dataset, which contains rescaled images from original MNIST over a factor of 4 concerning training data and over a factor of 16 concerning testing data. It is demonstrated that the resulting approach allows for scale generalization, enabling good performance for classifying patterns at scales not present in the training data.

description: We simulate, using nonperturbative methods, the real-time dynamics of small bubbles of "false vacuum" in a quantum spin chain near criticality, where the low-energy physics is described by a relativistic (1+1)-dimensional quantum field theory. We consider bubbles whose walls are kink and antikink quasiparticle excitations, so that wall collisions are kink-antikink scattering events. To construct these bubbles in the presence of strong correlations, we extend a recently proposed matrix product state (MPS) ansatz for quasiparticle wavepackets. We simulate dynamics within a window of about 1000 spins embedded in an infinite chain at energies of up to about 5 times the mass gap. By choosing the wavepacket width and the bubble size appropriately, we avoid strong lattice effects and observe relativistic kink-antikink collisions. We use the MPS quasiparticle ansatz to detect scattering outcomes. (i) In the Ising model, with transverse and longitudinal fields, we do not observe particle production despite nonintegrability (supporting recent observations of nonthermalizing states in this model). (ii) Switching on an additional interaction, we see production of confined and unconfined particle pairs. We characterize the amount of entanglement generated as a function of energy and time and conclude that our classical simulation methods will ultimately fail as these increase. We anticipate that kink-antikink scattering in 1+1 dimensions will be an instructive benchmark problem for future quantum computers and analog quantum simulators.
