description: Abstract

Using non-planar (3D) transistor architectures like FinFETs and Gate-all-around (GAA) FETs is a major advancement in the electrical industry. Multiple considerations have shown that 3D transistors are replacing 2D planar transistors. Short channel effects may be mitigated by using 3D transistors to adjust channel area. However, silicon dioxide (SiO2) dielectric performance limits device scaling. FinFETs using HK-MG materials can better manipulate channel electrons, improving device performance. In FinFET technology, HK-MG materials are compatible with traditional manufacturing methods, meeting the need for a replacement to SiO2. Hafnium and Titanium oxides are promising high-k dielectrics for submicron electronics. This study uses Ashby's methods to choose high-k metal gate (HK-MG) materials for FinFETs. The goal is to simulate energy band-gap, electric field distribution, charge density, and surface potential to prove these materials can replace SiO2.FinFET with HK-MG improves band-gap Energy (Eg) in addition to Electric Field Density, Surface Potential and Charge Density Distribution. With the use of High-k materials the corresponding bandgap energy is reduced. With Si. Ge, GaAs, InN and GaN the Eg (eV) was reduced to about 0.613eV, 0.08eV, 0.879eV, 1.932eV and 1.148eV respectively. As a result, GaAs, InN, and GaN as metal gate (MG) materials are more appropriate candidates than classic Si materials. High-k dielectric oxide (HK) materials and Metal Gates (MG) are examined for energy band-gap, electric field distribution, charge density, and surface potential in this work. Semiconductors with better electron mobility than silicon are better for high-frequency applications. GaN's high mobility and power density, which dissipates heat from tiny components, are noteworthy.
Universal avalanche statistics and triggering close to failure in a mean field model of rheological fracture

description: The hypothesis of critical failure relates the presence of an ultimate stability point in the structural constitutive equation of materials to a divergence of characteristic scales in the microscopic dynamics responsible for deformation. Avalanche models involving critical failure have determined common universality classes for stick-slip processes and fracture. However, not all empirical failure processes exhibit the trademarks of criticality. The rheological properties of materials introduce dissipation, usually reproduced in conceptual models as a hardening of the coarse grained elements of the system. Here, we investigate the effects of transient hardening on (i) the activity rate and (ii) the statistical properties of avalanches. We find the explicit representation of transient hardening in the presence of generalized viscoelasticity and solve the corresponding mean field model of fracture. In the quasistatic limit, the accelerated energy release is invariant with respect to rheology and the avalanche propagation can be reinterpreted in terms of a stochastic counting process. A single universality class can be defined from such analogy, and all statistical properties depend only on the distance to criticality. We also prove that inter-event correlations emerge due to the hardening --- even in the quasistatic limit --- that can be interpreted as "aftershocks" and "foreshocks".

description: We consider a class of numerical approximations to the Caputo fractional derivative. Our assumptions permit the use of nonuniform time steps, such as is appropriate for accurately resolving the behavior of a solution whose derivatives are singular at~$t=0$. The main result is a type of fractional Grönwall inequality and we illustrate its use by outlining some stability and convergence estimates of schemes for fractional reaction-subdiffusion problems. This approach extends earlier work that used the familiar L1 approximation to the Caputo fractional derivative, and will facilitate the analysis of higher order and linearized fast schemes.

description: The Herschel Lensing Survey (HLS) takes advantage of gravitational lensing by massive galaxy clusters to sample a population of high-redshift galaxies which are too faint to be detected above the confusion limit of current far-infrared/submillimeter telescopes. Measurements from 100–500 μm bracket the peaks of the far-infrared spectral energy distributions of these galaxies, characterizing their infrared luminosities and star formation rates. We introduce initial results from our science demonstration phase observations, directed toward the Bullet cluster (1E0657-56). By combining our observations with LABOCA 870 μm and AzTEC 1.1 mm data we fully constrain the spectral energy distributions of 19 MIPS 24 μm-selected galaxies which are located behind the cluster. We find that their colors are best fit using templates based on local galaxies with systematically lower infrared luminosities. This suggests that our sources are not like local ultra-luminous infrared galaxies in which vigorous star formation is contained in a compact highly dust-obscured region. Instead, they appear to be scaled up versions of lower luminosity local galaxies with star formation occurring on larger physical scales.

description: We study the properties of quarkonia inside a bulk-viscous quark gluon plasma. The non-equilibrium nature of the medium is encoded in the deformed distribution functions of thermal quarks and gluons, with which we compute the dielectric permittivity within the hard thermal loop approximation at one-loop. The modified dielectric permittivity is used to calculate the in-medium heavy quark potential, and using the potential we compute spectral functions, which reflect the physical properties of heavy quarkonia. We discuss how the bulk viscous effect influences quantities such as binding energies and thermal widths. Based on those properties, we discuss the implications of the bulk viscous effect on the physical observables such as $ ψ' $ to $ J/ψ$ ratio and the nuclear modification factor, $R_{AA}$. In particular, we argue that the nuclear modification factors of excited and ground states show different sensitivities to the bulk viscous nature of a plasma, which is potentially useful for the critical point search.

Our zero-field $μ$SR results provide a direct evidence of a fluctuating collective paramagnetic state down to 60 mK, supported by a wipe-out of the Ga nuclear magnetic resonance (NMR) signal below 25 K. At 60 mK a dynamics crossover to a much more static state is observed by $μ$SR in magnetic fields above 0.5 T. Accordingly, the NMR signal is recovered at low $T$ above a threshold field, revealing a rapid temperature and field variation of the magnetic fluctuations.

description: Dieser deutschsprachige Text von 1831 wurde als Einleitung zu der ersten Ausgabe der Statuten einer Hamburger Krankenpflegegesellschaft gedruckt, die scheinbar nicht erhalten geblieben sind. Sie ging aber auch den überarbeiteten Statuten des gleichen Vereins von 1836 voraus und wird in diesem Zusammenhang im Folgenden erläutert. In der Einleitung werden die Werte und Prinzipien des Vereins, der sehr allgemein als Verein für Krankenpflege bezeichnet wird, vorgestellt. Der Verein war ein moderner freiwilliger Zusammenschluss, der den religiös motivierten Rahmen der frühneuzeitlichen jüdischen hevrot traditionelle jüdische Vereine hinter sich gelassen und sich der Aufklärung und bürgerlichen Werten verschrieben hatte. Tatsächlich besagen weder die Einleitungnoch die Satzung selbst, dass diese Krankenpflegegesellschaft von Juden oder für Juden gegründet wurde. Vielmehr erwähnt die Einleitung, dass „Mitglieder des Kaufmanns=Standes“ den Verein für solche Kaufleute gegründet hatten, welche „Individuen der gebildeten Klassen“ waren (S. 1). Die Namen der Unterzeichner des Vorwortes von 1836 und die Tatsache, dass das Dokument heute in den Central Archives for the History of the Jewish People in Jerusalem aufbewahrt wird, deuten jedoch darauf hin, dass der Verein zumindest weitestgehend jüdische Mitglieder hatte. Einige der Unterzeichner haben eindeutig jüdische Namen, wie David J. Levi, und andere, wie Siegmund Robinow und J. M. Warburg, gehörten zu bekannten jüdischen Familien in Hamburg, die mit dem Israelitischen Tempel verbunden waren.

description: This work presents a two-stage text line detection method for historical documents. Each detected text line is represented by its baseline. In a first stage, a deep neural network called ARU-Net labels pixels to belong to one of the three classes: baseline, separator or other. The separator class marks beginning and end of each text line. The ARU-Net is trainable from scratch with manageably few manually annotated example images (less than 50). This is achieved by utilizing data augmentation strategies. The network predictions are used as input for the second stage which performs a bottom-up clustering to build baselines. The developed method is capable of handling complex layouts as well as curved and arbitrarily oriented text lines. It substantially outperforms current state-of-the-art approaches. For example, for the complex track of the cBAD: ICDAR2017 Competition on Baseline Detection the F-value is increased from 0.859 to 0.922. The framework to train and run the ARU-Net is open source.

description: 1. Lipid metabolism is an indispensable process in an organism, though little is known about the regulatory mechanisms of fat deposition in different types of adipose tissue. 2. The differentially expressed genes related to triglyceride (TG) metabolism between abdominal and intramuscular fat of Beijing-You chickens were investigated in this study. 3. TG content in abdominal fat (349.7 mg/g) was significantly higher (P<0.01) than in the breast and thigh (12.3 mg/g and 24.8 mg/g, respectively). 4. Using Agilent chicken gene expression profiling in adipose tissues between abdominal fat and muscle (breast and thigh), certain representative genes related to fatty acid metabolism, lipoprotein catabolism and esterification reactions were significantly up-regulated (P<0.05 or P< 0.01). 5. Genes involved in fatty acid oxidation or carbohydrate utilisation were significantly up- or down-regulated (P<0.05 or P<0.01), including those involved with highly enriched pathways of lipid metabolism (PPAR, Wnt pathway, inositol phosphate metabolism), cell junctions (focal adhesion, regulation of actin cytoskeleton), and muscle contraction. 6. Overall, higher TG levels were observed in abdominal fat tissue than in adipose tissues of breast and thigh, which could be regulated through gene expression of pathways related to lipid metabolism (PPAR, Wnt pathway, inositol phosphate metabolism), cell junctions (focal adhesion, regulation of actin cytoskeleton), and muscle contraction. These results provide clues to understanding the molecular mechanisms of TG metabolism between abdominal and intramuscular fat.

description: This German-language text from 1831 was the introduction to the first edition of the statutes of a Hamburg sick-care society, which seem not to have been preserved. However, it also preceded the revised statutes of the same association from 1836, and is discussed below in this context. The introduction lays out the values and the principles of the association, called most generically Association for Sick-Care Verein für Kranken=Pflege. The association was a modern voluntary association that had left behind the religiously motivated framework of early modern Jewish hevrot fellowships or confraternities and had adopted Enlightenment and bourgeois or middle-class values. In fact, neither the introduction nor the statutes themselves state that this sick-care society was established by Jews or for Jews. Rather, the introduction informs us that “members of the merchant order” founded the association for merchants who were “individuals of the educated classes” (p. 1). However, the names of the signatories of the 1836 preface and the fact that the document is housed today in the Central Archives for the History of the Jewish People in Jerusalem suggest that the association had at least a largely Jewish membership. Some of the signatories have distinctly Jewish names, such as David J. Levi, and others, such as Siegmund Robinow and J. M. Warburg, belonged to well-known Jewish families in Hamburg, associated with the Reform Temple.

description: Interlayer stacking order has recently emerged as a unique degree of freedom to control crystal symmetry and physical properties in two-dimensional van der Waals (vdW) materials and heterostructures. By tuning the layer stacking pattern, symmetry-breaking and electric polarization can be created in otherwise non-polar crystals, whose polarization reversal depends on the interlayer sliding motion. Herein, we demonstrate that in a vdW layered ferroelectric, its existing polarization is closely coupled to the interlayer sliding driven by hydrostatic pressure. Through combined structural, electrical, vibrational characterizations, and theoretical calculations, we clearly map out the structural evolution of CuInP2S6 under pressure. A tendency towards a high polarization state is observed in the low-pressure region, followed by an interlayer-sliding-mediated phase transition from a monoclinic to a trigonal phase. Along the transformation pathway, the displacive-instable Cu ion serves as a pivot point that regulates the interlayer interaction in response to external pressure. The rich phase diagram of CuInP2S6, which is enabled by stacking orders, sheds light on the physics of vdW ferroelectricity and opens an alternative route to tailoring long-range order in vdW layered crystals.

description: Relaxation of a non-equilibrium state in a disordered metal with a spin-dependent electron energy distribution is considered. The collision integral due to the electron-electron interaction is computed within the approximation of a two-quasiparticle scattering. We show that the spin-flip scattering processes with a small energy transfer may lead to the divergence of the collision integral for a quasi one-dimensional wire. This divergence is present only for a spin-dependent electron energy distribution which corresponds to the total electron spin magnetization M=0 and only for non-zero interaction in the triplet channel. In this case a non-perturbative treatment of the electron-electron interaction is needed to provide an effective infrared cut-off.

description: Prolonged paradoxical sleep deprivation (PSD) and cold stress (CS) are known to cause sympathoexcitation and increase the risk of cardiovascular disease. The present study examined the effect of PSD with CS on hemodynamic perturbations by investigating blood pressure and heart rate variability (BPV and HRV) in conscious rats. Adult male Sprague-Dawley rats were divided into three groups (n = 10, each): normal sleep (NS), PSD of 72 h, and recovery sleep of 7 days after PSD. When compared with NS, PSD increased systolic blood pressure in all three conditions: before CS (PreCS), CS, and after CS (PostCS). The PSD also increased heart rate in both PreCS and PostCS. Furthermore, spectral power changes were observed throughout the experiment. The PSD increased very-low-frequency BPV in PreCS, decreased very-low-frequency HRV in CS, and increased low-frequency BPV in all three conditions. The PSD increased low-frequency HRV in PreCS, increased high-frequency BPV in both CS and PostCS, and also increased high-frequency HRV in both PreCS and CS but decreased that in PostCS. On the other hand, when compared with PSD, recovery sleep has reversed most cardiovascular changes in PSD toward the NS level. However, when compared with NS, spectral powers of very-low-frequency BPV in the recovery phase showed a lower level. These results showed that in the resting condition, PSD might evoke sympathoexcitation with a tendency to increase both very-low-frequency BPV and very-low-frequency HRV, as the intensified myogenic oscillations. However, in the CS condition, PSD evoked the sympathoexcitation yet might attenuate such myogenic oscillations.

description: Recent advances have made it possible to obtain two-dimensional line-of-sight magnetic field maps of the solar corona from spectropolarimetric observations of the Fe XIII 1075 nm forbidden coronal emission line. Together with the linear polarization measurements that map the azimuthal direction of the coronal magnetic field, these coronal vector magnetograms now allow for direct observational testing of theoretical coronal magnetic field models. This paper presents a study testing the validity of potential-field coronal magnetic field models. We constructed a theoretical coronal magnetic field model of active region AR 10582 observed by the SOLARC coronagraph in 2004 by a global potential field extrapolation of the synoptic map of Carrington Rotation 2014. Synthesized linear and circular polarization maps from thin layers of the coronal magnetic field model above the active region along the line of sight are compared with the observed maps. We found that reasonable agreement occurs from layers located just above the sunspot of AR 10582, near the plane of the sky. This result provides the first observational evidence that potential field extrapolation can yield a reasonable approximation of the magnetic field configuration of the solar corona for simple and stable active regions.

description: We show that, for a certain class of partitions and an even number of variables of which half are reciprocals of the other half, Schur polynomials can be factorized into products of odd and even orthogonal characters. We also obtain related factorizations involving sums of two Schur polynomials, and certain odd-sized sets of variables. Our results generalize the factorization identities proved by Ciucu and Krattenthaler (Advances in combinatorial mathematics, 39-59, 2009) for partitions of rectangular shape. We observe that if, in some of the results, the partitions are taken to have rectangular or double-staircase shapes and all of the variables are set to 1, then factorization identities for numbers of certain plane partitions, alternating sign matrices and related combinatorial objects are obtained.

Neutron matter at low density and the unitary limit

subject: FOS: Physical sciences

description: Neutron matter at low density is studied within the hole-line expansion. Calculations are performed in the range of Fermi momentum $k_F$ between 0.4 and 0.8 fm$^{-1}$. It is found that the Equation of State is determined by the $^1S_0$ channel only, the three-body forces contribution is quite small, the effect of the single particle potential is negligible and the three hole-line contribution is below 5% of the total energy and indeed vanishing small at the lowest densities. Despite the unitary limit is actually never reached, the total energy stays very close to one half of the free gas value throughout the considered density range. A rank one separable representation of the bare NN interaction, which reproduces the physical scattering length and effective range, gives results almost indistinguishable from the full Brueckner G-matrix calculations with a realistic force. The extension of the calculations below $k_F = 0.4$ fm$^{-1}$ does not indicate any pathological behavior of the neutron Equation of State.

description: Objectives: Quantitative sensory testing (QST) is a method to assess somatosensory function in osteoarthritis (OA), but reliability data on the performance of different QST modalities on different joint structures are missing. The main aims of our study were to assess intertester and intratester reliability of tactile detection thresholds (TDTs), vibration detection thresholds (VDTs), and pressure pain thresholds (PPTs) on different knee joint structures. Method: In total, 32 subjects with knee OA and 32 volunteers with healthy knees participated. TDTs, VDTs, and PPTs were examined on the medial tibial condyle, medial tibiofemoral joint line, and rectus femoris muscle twice on the first visit and once after 1–3 weeks. Results: The intratester and intertester intraclass correlation coefficients (ICCs) of PPT measurements varied from 0.60 to 0.90 on different joint structures, showing good to excellent reliability. Intratester reliability (ICC 0.64–0.76) of VDT measurements was higher than intertester reliability (0.48–0.75). The intertester reliability of TDT measurements was excellent in subjects with knee OA (ICC 0.84–0.86) and good in controls (0.67) on the medial tibial condyle. Intratester reliability of TDT measurements varied greatly. Conclusion: PPT testing is a reliable tool for measuring pain thresholds on different joint structures. The VDT measurement is reliable when taken by the same evaluator. The reliability of TDT measurements depends on the site of the measurement.

description: Two circumbinary planets have been recently discovered by TESS. The main aim of this work is to explore whether it is possible, besides the discovered circumbinary planet, to have an Earth-like planet within the habitable zone of the system. We carry out numerical simulations over the whole range of the two habitable zones in order to see whether an Earth mass planet can exist there. We find that both systems seem to be able to host an additional planet in their habitable zone. We construct dynamically informed habitable zones and we find that a large percentage of the habitable zone can be suitable for a planet to retain liquid water on its surface no matter what its orbital evolution will be. Moreover, we investigate the possibility to detect an Earth-like planet in the habitable zone of the two systems. We find that for both systems, if such a planet existed, the radial velocity and astrometry signals would be rather small to be detected by our current instruments. Some discussion is also made for the dynamical evolution of the existing planet.

description: We report the detection of OH 1667 MHz and wide HI 21cm absorption at $z \sim 0.67$ towards the red quasar 1504+377, with the Green Bank Telescope and the Giant Metrewave Radio Telescope. The HI 21cm absorption extends over a velocity range of $\sim 600$ km/s blueward of the quasar redshift ($z=0.674$), with the new OH 1667 MHz absorption component at $\sim -430$ \kms, nearly coincident with earlier detections of mm-wave absorption at $z \sim 0.6715$. The atomic and molecular absorption appear to arise from a fast gas outflow from the quasar, with a mass outflow rate ${\dot M} \sim 12 M_\odot$ yr$^{-1}$ and a molecular hydrogen fraction $f_{\rm H_2} \equiv (N_{\rm H_2}/N_{\rm HI}) \sim 0.2$. The radio structure of 1504+377 is consistent with the outflow arising due to a jet-cloud interaction, followed by rapid cooling of the cloud material. The observed ratio of HCO$^+$ to OH column densities is $\sim 20$ times higher than typical values in Galactic and high-$z$ absorbers. This could arise due to small-scale structure in the outflowing gas on sub-parsec scales, which would also explain the observed variability in the HI 21cm line.

description: The primary objectives of this research were to clinically examine the New Jersey Low Contact Stress (LCS)™ Rotating Platform and Meniscal knee bearing systems and to investigate the tribological properties of a new polymer for potential application in total joint replacement. Thus, clinical studies were performed on subjects having the LCSTM Rotating Platform knee bearing and subjects having the LCS™ meniscal knee bearing. The results indicated that there was a statistically significant difference in the braking force for both implant groups when compared to a control group. There was also a statistically significant difference noted for the LCS™ Rotating Platform group with regards to propulsion force and time spent during stance phase. The tribological studies demonstrated that LaRCTM_SI (3% Offset) along with particulate reinforcements of Graphite, Aluminum Oxide (Al2O3), X-903 and Polytetrafluoroethylene (PTFE) produced significantly higher wear rates than the reference material, Ultra High Molecular Weight Polyethylene (UHMWPE). The results obtained for the coefficient of friction demonstrated higher values when compared to the reference material, UHMWPE.

description: We consider a quantum graph as a model of graphene in constant magnetic field and describe the density of states in terms of relativistic Landau levels satisfying a Bohr--Sommerfeld quantization condition. That provides semiclassical corrections (with the magnetic flux as the semiclassical parameter) in the study of magnetic oscillations.

description: Amir Temur's activity in ancient times and the Middle Ages is considered one of the three great generals. These are: Alexander Makedonskiy, Chigizkhan and Amir Temur. They worked in different eras and under completely different historical conditions. Therefore, it is difficult to compare them. Nevertheless, French and Russian researchers studied the lives of these great generals and gave the highest praise to Amir Temur.

description: The concept of gauge field is a cornerstone of modern physics and the synthetic gauge field has emerged as a new way to manipulate particles in many disciplines. In optics, several schemes of Abelian synthetic gauge fields have been proposed. Here, we introduce a new platform for realizing synthetic SU(2) non-Abelian gauge fields acting on two-dimensional optical waves in a wide class of anisotropic materials and discover novel phenomena. We show that a virtual non-Abelian Lorentz force arising from material anisotropy can induce light beams to travel along Zitterbewegung trajectories even in homogeneous media. We further design an optical non-Abelian Aharonov-Bohm system which results in the exotic spin density interference effect. We can extract the Wilson loop of an arbitrary closed optical path from a series of gauge fixed points in the interference fringes. Our scheme offers a new route to study SU(2) gauge field related physics using optics.

Magnetic field emergence in quiet Sun granules

description: We describe a new form of small-scale magnetic flux emergence in the quiet Sun. This process seems to take vertical magnetic fields from the solar interior to the photosphere, where they appear above granular convection cells. High-cadence time series of spectropolarimetric measurements obtained by Hinode in a quiet region near disk center are analyzed. We extract line parameters from the observed Stokes profiles and study their evolution with time. The circular polarization maps derived from the observed \ion{Fe}{i} 630 nm lines show clear magnetic signals emerging at the center of granular cells. We do not find any evidence for linear polarization signals associated with these events. The magnetic flux patches grow with time, occupying a significant fraction of the granular area. The signals then fade until they disappear completely. The typical lifetime of these events is of the order of 20 minutes. No significant changes in the chromosphere seem to occur in response to the emergence, as revealed by co-spatial \ion{Ca}{ii} H filtergrams. The Stokes I and V profiles measured in the emerging flux concentrations show strong asymmetries and Doppler shifts. The origin of these events is unclear at present, but we suggest that they may represent the emergence of vertical fields lines from the bottom of the photosphere, possibly dragged by the convective upflows of granules. Preliminary inversions of the Stokes spectra indicate that this scenario is compatible with the observations. The emergence of vertical field lines is not free from conceptual problems, though.

description: The observation of the nature and world represents the main source of human knowledge on the basis of our reason. At the present it is also the use of precise measurement approaches, which may contribute significantly to the knowledge of the world but cannot substitute fully the knowledge of the whole reality obtained also with the help of our senses. It is not possible to omit the ontological nature of matter world. However, any metaphysical consideration was abandoned when mainly under the influence of positivistic philosophy phenomenological models started to be strongly preferred and any intuitive approach based on human senses has been refused. Their success in application region has seemed to provide decisive support for such preference. However, it is limited practically to the cases when only interpolation between measured data is involved. When the extrapolation is required the ontological models are much more reliable and practically indispensable in realistic approach.

Indigineous Knowledge

description: Indigenous peoples are on the front lines of climate change. In the face of rising temperatures and more extreme weather events, Indigenous communities increasingly use Earth observation satellite data to adapt to climate change and protect their unique relationship with their environment. Satellite data can be used to track environmental changes such as deforestation and changes in sea ice. This information can help Indigenous and local communities adapt and respond to the impacts of climate change so that their way of life is sustainable for future generations.   
In recent years, the GEO community has seen significant progress in adopting and advancing Open Knowledge principles. These innovations have sparked essential discussions on how these emerging concepts and technologies can better support the use of Indigenous Knowledge and Data. 
This session featured diverse speakers representing various regions and thematic areas where GEO is actively engaged. Together, they explored the primary needs of the Indigenous community in GEO (such as infrastructure and capacity development) and discussed how Open Knowledge practices can enhance their activities.

Collimation and Radiative Deceleration of Jets in TeV AGNs

description: We consider some implications of the rapid X-ray and TeV variability observed in M87 and the TeV blazars. We outline a model for jet focusing and demonstrate that modest radiative cooling can lead to recollimation of a relativistic jet in a nozzle having a very small cross-sectional radius. Such a configuration can produce rapid variability at large distances from the central engine and may explain recent observations of the HST-1 knot in M87. Possible applications of this model to TeV blazars are discussed. We also discuss a scenario for the very rapid TeV flares observed with HESS and MAGIC in some blazars, that accommodates the relatively small Doppler factors inferred from radio observations.

description: Deconfined quantum critical points govern continuous quantum phase transitions at which fractionalized (deconfined) degrees of freedom emerge. Here we study dynamical signatures of the fractionalized excitations in a quantum magnet (the easy-plane J-Q model) that realize a deconfined quantum critical point with emergent O(4) symmetry. By means of large-scale quantum Monte Carlo simulations and stochastic analytic continuation of imaginary-time correlation functions, we obtain the dynamic spin structure factors in the $S^{x}$ and $S^{z}$ channels. In both channels, we observe broad continua that originate from the deconfined excitations. We further identify several distinct spectral features of the deconfined quantum critical point, including the lower edge of the continuum and its form factor on moving through the Brillouin Zone. We provide field-theoretical and lattice model calculations that explain the overall shapes of the computed spectra, which highlight the importance of interactions and gauge fluctuations to explaining the spectral-weight distribution. We make further comparisons with the conventional Landau O(2) transition in a different quantum magnet, at which no signatures of fractionalization are observed. The distinctive spectral signatures of the deconfined quantum critical point suggest the feasibility of its experimental detection in neutron scattering and nuclear magnetic resonance experiments.
