description: A resonant inelastic x-ray scattering (RIXS) study of overdamped spin-excitations in slightly underdoped La$_{2-x}$Sr$_{x}$CuO$_4$ (LSCO) with $x=0.12$ and $0.145$ is presented. Three high-symmetry directions have been investigated: (1) the antinodal $(0,0)\rightarrow (1/2,0)$, (2) the nodal $(0,0)\rightarrow (1/4,1/4)$ and (3) the zone boundary direction $(1/2,0)\rightarrow (1/4,1/4)$ connecting these two. The overdamped excitations exhibit strong dispersions along (1) and (3), whereas a much more modest dispersion is found along (2). This is in strong contrast to the undoped compound La$_{2}$CuO$_4$ (LCO) for which the strongest dispersions are found along (1) and (2). The $t-t^{\prime}-t^{\prime\prime}-U$ Hubbard model used to explain the excitation spectrum of LCO predicts $-$ for constant $U/t$ $-$ that the dispersion along (3) scales with $(t^{\prime}/t)^2$. However, the diagonal hopping $t^{\prime}$ extracted on LSCO using single-band models is low ($t^{\prime}/t\sim-0.16$) and decreasing with doping. We therefore invoked a two-orbital ($d_{x^2-y^2}$ and $d_{z^2}$) model which implies that $t^{\prime}$ is enhanced. This effect acts to enhance the zone-boundary dispersion within the Hubbard model. We thus conclude that hybridization of $d_{x^2-y^2}$ and $d_{z^2}$ states has a significant impact on the zone-boundary dispersion in LSCO.

description: This document reports the up-to-date progress towards achieving smart E2E network slicing. It focuses on the prototyping of enabling technologies for E2E network slicing across network segments, their intent-based Management and Orchestration, and AI-based RAN resource allocation enabled with the Cognitive Plane’s Multi-Agent Deep Reinforcement Learning platform. Moreover, it covers preliminary integration work between different network slicing enablers over the E2E data path, with the MANO plane, and with the MA-DRL platform. Together, these technological enablers, algorithmic advances and initial integration work lay down the foundation for implementing the targeting E2E slicing system.

description: Selon le folkloriste russe Vladimir Propp, la fonction du « manque » constitue un élément structurel du conte extrêmement important, dans la mesure où il donne à celui-ci son mouvement, mobilisant la quête du héros. Dans le cadre de cet article, nous tentons d’analyser comment quelques auteurs se sont appropriés au fil du temps cet élément fondamental du conte, l’investissant chaque fois d’une signification particulière, en vue de l’insérer dans un contexte socioculturel précis. À cet égard, nous nous penchons sur trois réécritures contemporaines qui revisitent « Le Petit Poucet » de Charles Perrault.

Fair densest subgraph across multiple graphs

Subjects: subject: Data Structures and Algorithms (cs.DS)

description: Many real-world networks can be modeled as graphs. Finding dense subgraphs is a key problem in graph mining with applications in diverse domains. In this paper, we consider two variants of the densest subgraph problem where multiple graph snapshots are given and the goal is to find a fair densest subgraph without over-representing the density among the graph snapshots. More formally, given a set of graphs and input parameter $α$, we find a dense subgraph maximizing the sum of densities across snapshots such that the difference between the maximum and minimum induced density is at most $α$. We prove that this problem is NP-hard and present an integer programming based, exact algorithm and a practical polynomial-time heuristic. We also consider a minimization variant where given an input parameter $σ$, we find a dense subgraph which minimizes the difference between the maximum and minimum density while inducing a total density of at least $σ$ across the graph snapshots. We prove the NP-hardness of the problem and propose two algorithms: an exponential time algorithm based on integer programming and a greedy algorithm. We present an extensive experimental study that shows that our algorithms can find the ground truth in synthetic dataset and produce good results in real-world datasets. Finally, we present case studies that show the usefulness of our problem.

description: We compare the two main techniques used for estimating the state of a physical system from unknown measurements: standard detector tomography and data-pattern tomography. Adopting linear inversion as a fair benchmark, we show that the difference between these two protocols can be traced back to the nonexistence of the reverse-order law for pseudoinverses. We capitalize on this fact to identify regimes where the data-pattern approach outperforms the standard one and vice versa. We corroborate these conclusions with numerical simulations of relevant examples of quantum state tomography.

Les doubles morales de Riquet à la houppe. Analyse linguistique comparée des contes de Perrault et Salvayre
Creators: name: Perusset, Alain
Publisher: name: Syn-Thèses
Year: 2023
Subjects: Linguistics; Argumentation; Perrault; Fairytale; Riquet

description: Rhetoric is a recurrent topic of Charles Perrault’s tales (1697). Riquet with the Tuft, one of the texts of his work, is no exception and even appears to be the tale that most thematizes this form of art. In one of its contemporary rewritings, De l'avantage d'être laid by Lydie Salvayre (2002), this argumentative dimension also occupies a preponderant place, but to manifest a different moral from the one defended in Perrault’s original tale. The objective of this article is to compare the morals of the two tales so as to put them in perspective with the period of their production. To this end, we will focus on the dialogical and argumentative sequences of the two main characters, Riquet and his ladylove, paying particular attention to their turn-taking and the stylistics of their conversations. This analysis relies on Jean-Michel Adam's textual linguistics for the analysis of dialogues, narratives and argumentative discourses (2017).

Neutrino-induced one-pion production revisited: the $ν_μn\toμ^- nπ^+$ channel

description: Understanding single pion production reactions on free nucleons is the first step towards a correct description of these processes in nuclei, which are important for signal and background contributions in current and near future accelerator neutrino oscillation experiments. In this work, we reanalyze our previous studies of neutrino-induced one-pion production on nucleons for outgoing $πN$ invariant masses below 1.4 GeV. Our motivation is to get a better description of the $ν_μn\toμ^- nπ^+$ cross section, for which current theoretical models give values significantly below data. This channel is very sensitive to the crossed $Δ(1232)$ contribution and thus to spin 1/2 components in the Rarita-Schwinger $Δ$ propagator. We show how these spin 1/2 components are nonpropagating and give rise to contact interactions. In this context, we point out that the discrepancy with experiment might be corrected by the addition of appropriate extra contact terms and argue that this procedure will provide a natural solution to the $ν_μn\toμ^- nπ^+$ puzzle. To keep our model simple, in this work we propose to change the strength of the spin 1/2 components in the $Δ$ propagator and use the $ν_μn\toμ^- nπ^+$ data to constraint its value. With this modification, we now find a good reproduction of the $ν_μn\toμ^- nπ^+$ cross section without affecting the good results previously obtained for the other channels. We also explore how this change in the $Δ$ propagator affects our predictions for pion photoproduction and find also a better agreement with experiment than with the previous model.

New constraints on the AME polarisation in bright galactic molecular complexes with QUIJOTE
Creators: name: Gonzalez, Raul Gonzalez
Publisher: name: Zenodo
Year: 2022

description: Anomalous microwave emission (AME) is an additional component of diffuse foreground emission that cannot be easily explained by synchrotron, free-free, or thermal dust emission. AME has been observed by numerous experiments in the frequency range ∼10–60 GHz within specific galactic clouds as ρ Ophiuchi, W43 or Perseus and potentially even in external galaxies. It is found to be very closely correlated with far infrared (FIR) emission associated with thermal emission from dust grains. However, its polarized properties are still uncertain as physical models predict varying levels of potential polarized emission, and there is no observational detection of AME polarised emission so far. Up to now the most accredited model is the “electric dipole emission from spinning dust grains". In this work we present new Q-U-I JOint Tenerife Experiment (QUIJOTE) 10–20 GHz maps in intensity and in polarisation of the ρ Ophiuchi molecular cloud AME region. We also provide new maps with improved sensitivity on W43 and we started a new analysis also for Perseus molecular cloud. These last regions have already been studied in past works. For each region we provide spectra over the frequency range 0.4–3000 GHz after combination with other publicly available intensity data, which confirm that the emission in the range between 10 and 60 GHz is dominated by AME in these regions.

description: Whenever the integrand of a gauge-theory loop amplitude can be arranged into a form where the BCJ duality between color and kinematics is manifest, a corresponding gravity integrand can be obtained simply via the double-copy procedure. However, finding such gauge-theory representations can be challenging, especially at high loop orders. Here we show that we can instead start from generic gauge-theory integrands, where the duality is not manifest, and apply a modified double-copy procedure to obtain gravity integrands that include contact terms generated by violations of dual Jacobi identities. We illustrate this with three-, four- and five-loop examples in N=8 supergravity.

description: Papillomaviruses, members of a group of dsDNA viruses associated with epithelial growths and tumors, have compact capsids assembled from 72 pentamers of the protein L1. We have determined the structure of bovine papillomavirus by electron cryomicrosopy (cryoEM), at ∼3.6 Å resolution. The density map, obtained from single-particle analysis of ∼4,000 particle images, shows the trace of the L1 polypeptide chain and reveals how the N- and C-terminal “arms” of a subunit (extensions from its β-jelly-roll core) associate with a neighboring pentamer. Critical contacts come from the C-terminal arm, which loops out from the core of the subunit, forms contacts (including a disulfide) with two subunits in a neighboring pentamer, and reinserts into the pentamer from which it emanates. This trace corrects one feature of an earlier model. We discuss implications of the structure for virion assembly and for pathways of infectious viral entry. We suggest that it should be possible to obtain image reconstructions of comparable resolution from cryoEM images of asymmetric particles. From the work on papillomavirus described here, we estimate that such a reconstruction will require about 1.5 million images to achieve the same number of averaged asymmetric units; structural variability will increase this number substantially.Data descriptionLinked at right is a stack (16 GB) of 5,546 images (MRC/CCP4 format) of bovine papillomavirus (BPV [1]) collected at 300 kV and a calibrated magnification of 56,588, giving a pixel size on the specimen of 1.237 Å. Alignment parameters determined by Frealign for each particle in the stack can also be found below, as well as a reconstruction of BPV (also MRC/CCP4 format). Ewald sphere and beamtilt correction were performed. The atomic coordinates contain the coordinates from one subunit (3IYJ.pdb) and the five surrounding subunits to enable exploration of inter-subunit contacts.

description: The motion of a charged particle in a nonuniform straight magnetic field with a uniform magnetic-field gradient is solved exactly in terms of elliptic functions. The connection between this problem and the guiding-center approximation is discussed. It is shown that, for this problem, the predictions of guiding-center theory agree very well with the orbit-averaged particle motion and hold well beyond the standard guiding-center limit $ε\equiv ρ/L \ll 1$, where $ρ$ is the gyromotion length scale and $L$ is the magnetic-field gradient length scale.

Mobility Edges in 1D Bichromatic Incommensurate Potentials

description: We theoretically study a one-dimensional (1D) mutually incommensurate bichromatic lattice system which has been implemented in ultracold atoms to study quantum localization. It has been universally believed that the tight-binding version of this bichromatic incommensurate system is represented by the well-known Aubry-Andre model. Here we establish that this belief is incorrect and that the Aubry-Andre model description, which applies only in the extreme tight-binding limit of very deep primary lattice potential, generically breaks down near the localization transition due to the unavoidable appearance of single-particle mobility edges (SPME). In fact, we show that the 1D bichromatic incommensurate potential system manifests generic mobility edges which disappear in the tight-binding limit, leading to the well-studied Aubry-Andre physics. We carry out an extensive study of the localization properties of the 1D incommensurate optical lattice without making any tight-binding approximation. We find that, for the full lattice system, an intermediate phase between completely localized and completely delocalized regions appears due to the existence of the SPME, making the system qualitatively distinct from the Aubry-Andre prediction. Using the Wegner flow approach, we show that the SPME in the real lattice system can be attributed to significant corrections of higher-order harmonics in the lattice potential which are absent in the strict tight-binding limit. We calculate the dynamical consequences of the intermediate phase in detail to guide future experimental investigations for the observation of 1D SPME and the associated intermediate phase. We consider effects of interaction numerically, and conjecture the stability of SPME to weak interaction effects, thus leading to the exciting possibility of an experimentally viable nonergodic extended phase in interacting 1D optical lattices.

description: Most theoretical studies of nanoscale transport in molecular junctions rely on the combination of the Landauer formalism with Kohn-Sham density functional theory (DFT) using standard local and semilocal functionals to approximate exchange and correlation effects. In many cases, the resulting conductance is overestimated with respect to experiments. Recent works have demonstrated that this discrepancy may be reduced when including many-body corrections on top of DFT. Here we study benzene-dithiol (BDT) gold junctions and analyze the effect of many-body perturbation theory (MBPT) on the calculation of the conductance with respect to different bonding geometries. We find that the many-body corrections to the conductance strongly depend on the metal-molecule coupling strength. In the BDT junction with the lowest coupling, many-body corrections reduce the overestimation on the conductance to a factor two, improving the agreement with experiments. In contrast, in the strongest coupling cases, many-body corrections on the conductance are found to be sensibly smaller and standard DFT reveals a valid approach.

description: We deal with quadratic metric-affine gravity (QMAG), which is an alternative theory of gravity and present a new explicit representation of the field equations of this theory. In our previous work we found new explicit vacuum solutions of QMAG, namely generalised pp-waves of parallel Ricci curvature with purely tensor torsion. Here we do not make any assumptions on the properties of torsion and write down our field equations accordingly. We present a review of research done thus far by several authors in finding new solutions of QMAG and different approaches in generalising pp-waves. We present two conjectures on the new types of solutions of QMAG which the ansatz presented in this paper will hopefully enable us to prove.

description: The new vector-like top partners with charge $2/3$ are a typical feature of many new physics models beyond the Standard Model (SM). We propose a search strategy for single production of top partners $T$ focusing on both the $T\to Wb$ and $T\to th$ decay channels at the Large Hadron Electron Collider (LHeC). Our analysis is based on a simplified model in which the top partner is an $SU(2)$ singlet, with couplings only to the third generation of SM quarks. We study the observability of the single $T$ through the processes $e^{+}p \to T(\to bW^{+})\barν_{e}\to b\ell^{+}+ \not E_T^{miss}$ and $e^{+}p \to T(\to th)\barν_{e}\to t(\to jj'b)h(\to b\bar{b}) \not E_T^{miss}$ at the LHeC with the proposed 140 GeV electron beam (with $80\%$ polarization) and 7 TeV proton beam. For three typical $T$-quark masses (800, 900 and 1000 GeV), the $3σ$ exclusion limits on the $TWb$ coupling are respectively presented for various values of the integrated luminosity.

description: In health technology assessment, decisions are based on complex cost-effectiveness models which, to be implemented, require numerous input parameters. When some of relevant estimates are not available the model may have to be simplified. Multi-parameter evidence synthesis allows to combine data from diverse sources of evidence resulting in obtaining estimates required in clinical decision-making that otherwise may not be available. We demonstrate how bivariate meta-analysis (BVMA) can be used to predict unreported estimate of a treatment effect enabling implementation of multi-state Markov model, which otherwise needs to be simplified. To illustrate this, we used an example of cost-effectiveness analysis for docetaxel in combination with prednisolone in metastatic hormone-refractory prostate cancer (mHRPC). BVMA was used to model jointly available data on treatment effects on overall survival (OS) and progression-free survival (PFS) to predict the unreported effect on PFS in a study evaluating docetaxel. Predicted treatment effect on PFS allowed implementation of a three-state Markov model comprising of stable disease, progressive disease and death states, whilst lack of the estimate restricted the model to two-state model (stable disease and death states). The two-state and three-state models were compared by calculating incremental cost-effectiveness ratios, which was much lower in the three-state model: £21966 per QALY gained compared to £30026 obtained from the two-state model. In contrast to the two-state model, the three-state model has the advantage of distinguishing patients who progressed from those who did not progress. The use of advanced meta-analytic technique helped to obtain relevant parameter estimate to populate a model which describes natural history more accurately, and at the same helped to prevent valuable clinical data from being discarded.

description: Wychowanie fizyczne dzieci w wieku przedszkolnym w literaturze pedagogicznej zajmuje bardzo ważne miejsce w kontekście wszechstronnego przygotowania dzieci do nauki szkolnej. Kluczową rolę odgrywa w tych działaniach odgrywa także właściwa pedagogiczna postawa samych rodziców: przestrzeganie norm higieny życia codziennego, uprawianie gimnastyki porannej, zdrowe wyżywienie, rekreacja ruchowa w czasie wolnym oraz zabiegi hartujące. Szczególną uwagę w monografii poświęcono roli gier i zabaw ruchowych w rozwoju motoryki dziecięcej (zwłaszcza, gdy gry i zabawy są przeprowadzane na świeżym powietrzu) oraz problematyce kreowania postaw prozdrowotnych u dzieci, takich jak: kwestia stworzenia pozytywnego klimatu psychologicznego, kultura pedagogiczna rodziców oraz odpowiedniego nastawienia, zarówno pomiędzy rodzicami jak i wobec dzieci. Poważne traktowanie wychowania fizycznego w rodzinie pozwala ukształtować u dziecka przyzwyczajenia i potrzebę uczestnictwa w systematycznych ćwiczeniach fizycznych. Monografia składa się z: wstępu, czterech rozdziałów, zakończenia oraz z bibliografii. Publikacja przeznaczona jest dla studentów, pracowników naukowych oraz nauczycieli. Rozdział pierwszy pt. „Aktywność ruchowa dzieci w wieku 3-7 lat” poświęcono problematyce dynamiki aktywności ruchowej dzieci w wieku 3-7 lat, a także formom optymizacji kształtowania cech motorycznych dzieci w wieku przedszkolnym. W rozdziale drugim pt. „Rozwój dzieci w wieku przedszkolnym” przedstawiono wzorce pedagogicznego, fizycznego i umysłowego rozwoju dzieci w wieku 3-7 lat. Zilustrowano również uwarunkowania przeprowadzenia kontroli rozwoju fizycznego dzieci w kontekście działań wychowawczych w rodzinie. Rozdział trzeci pt. „Uwarunkowania prawidłowego rozwoju i wzmacnia zdrowia dzieci” skupia się na zaleceniach i propozycjach dotyczących przestrzegania przez rodziny przedszkolaków zdrowego trybu życia, zasad hartowania, kształtowania prawidłowych postaw oraz zapobiegania powstawania płaskostopia. Rozdział czwarty pt. „Wychowanie fizyczne dzieci w wieku przedszkolnym” poświęcono zagadnieniom dotyczących organizacji i stosowaniu różnorakich form wychowania fizycznego u dzieci w wieku przedszkolnym przez rodziców. Monografia przeznaczona jest dla studentów pedagogiki, pracowników naukowych oraz doktorantów zajmujących się problematyką wychowania w rodzinie, rozwoju i dobrostanu dzieci.

description: We extend the matter bounce scenario to a more general theory in which the background dynamics and cosmological perturbations are generated by a $k$-essence scalar field with an arbitrary sound speed. When the sound speed is small, the curvature perturbation is enhanced, and the tensor-to-scalar ratio, which is excessively large in the original model, can be sufficiently suppressed to be consistent with observational bounds. Then, we study the primordial three-point correlation function generated during the matter-dominated contraction stage and find that it only depends on the sound speed parameter. Similar to the canonical case, the shape of the bispectrum is mainly dominated by a local form, though for some specific sound speed values a new shape emerges and the scaling behaviour changes. Meanwhile, a small sound speed also results in a large amplitude of non-Gaussianities, which is disfavored by current observations. As a result, it does not seem possible to suppress the tensor-to-scalar ratio without amplifying the production of non-Gaussianities beyond current observational constraints (and vice versa). This suggests an extension of the previously conjectured no-go theorem in single field nonsingular matter bounce cosmologies, which rules out a large class of models. However, the non-Gaussianity results remain as a distinguishable signature of matter bounce cosmology and have the potential to be detected by observations in the near future.

description: Complementary to scattering techniques, scanning tunnelling microscopy provides atomic-scale real space information about a material's electronic state of matter. State-of-the-art designs of a scanning tunnelling microscope (STM) allow measurements at millikelvin temperatures with unprecedented energy resolution. Therefore, this instrument excels in probing the superconducting state at low temperatures and especially its local quasiparticle excitations as well as bosonic degrees of freedom.

description: The paper presents a computational study of the ground-state magnetic phases of a selected bilayer graphene nanoflake in external electric field and magnetic field. The electric field has parallel and perpendicular component while the magnetic field is oriented in plane. The system consists of two rectangular layers having armchair edges and zigzag terminations with Bernal stacking. The theoretical model is based on a tight binding Hamiltonian with Hubbard term. The magnetic phase diagram involving the total spin is constructed, showing the stability areas of phases with total spin values equal to 0 and 1. A significant stability range of antiferromagnetic, layer-like arrangements is found and extensively discussed. The possibility of switching between nonmagnetic, antiferromagnetic and ferrimagnetic phases with both components of external electric field is demonstrated, being a manifestation of a magnetoelectric effect. The influence of magnetic field on the phase diagrams is analysed.

description: The local kinematic formulas on complex space forms induce the structure of a commutative algebra on the space $\mathrm{Curv}^{\mathrm{U}(n)*}$ of dual unitarily invariant curvature measures. Building on the recent results from integral geometry in complex space forms, we describe this algebra structure explicitly as a polynomial algebra. This is a short way to encode all local kinematic formulas. We then characterize the invariant valuations on complex space forms leaving the space of invariant angular curvature measures fixed.

Bias voltage effects on tunneling magnetoresistance in Fe/MgAl${}_2$O${}_4$/Fe(001) junctions: Comparative study with Fe/MgO/Fe(001) junctions

description: We investigate bias voltage effects on the spin-dependent transport properties of Fe/MgAl${}_2$O${}_4$/Fe(001) magnetic tunneling junctions (MTJs) by comparing them with those of Fe/MgO/Fe(001) MTJs. By means of the nonequilibrium Green's function method and the density functional theory, we calculate bias voltage dependences of magnetoresistance (MR) ratios in both the MTJs. We find that in both the MTJs, the MR ratio decreases as the bias voltage increases and finally vanishes at a critical bias voltage $V_{\rm c}$. We also find that the critical bias voltage $V_{\rm c}$ of the MgAl${}_2$O${}_4$-based MTJ is clearly larger than that of the MgO-based MTJ. Since the in-plane lattice constant of the Fe/MgAl${}_2$O${}_4$/Fe(001) supercell is twice that of the Fe/MgO/Fe(001) one, the Fe electrodes in the MgAl${}_2$O${}_4$-based MTJs have an identical band structure to that obtained by folding the Fe band structure of the MgO-based MTJs in the Brillouin zone of the in-plane wave vector. We show that such a difference in the Fe band structure is the origin of the difference in the critical bias voltage $V_{\rm c}$ between the MgAl${}_2$O${}_4$- and MgO-based MTJs.

description: The Carnegie-Chicago Hubble Program seeks to anchor the distance scale of Type Ia supernovae via the Tip of the Red Giant Branch (TRGB). Based on deep $Hubble$ $Space$ $Telescope$ ACS/WFC imaging, we present an analysis of the TRGB for the metal-poor halo of NGC 1365, a giant spiral galaxy in the Fornax Cluster that is host to the supernova SN2012fr. We have measured its extinction-corrected TRGB magnitude to be F814W $= 27.34 \pm 0.03_{stat} \pm0.01_{sys}$ mag. In advance of future direct calibration by $Gaia$, we set a provisional TRGB luminosity via the Large Magellanic Cloud and find a true distance modulus $μ_0 = 31.29 \pm 0.04_{stat}\pm0.05_{sys}$ mag or $D = 18.1 \pm 0.3_{stat} \pm0.4_{sys}$ Mpc. This high-fidelity measurement shows excellent agreement with recent Cepheid-based distances to NGC 1365 and suggests no significant difference in the distances derived from stars of Population I and II. We revisit the error budget for the $CCHP$ path to the Hubble Constant based on this analysis of one of our most distant hosts, finding a 2.5% measurement is feasible with our current sample.

description: The physical reason why one can calculate with similar accuracy, as compared to the experimental data, the absolute cross section associated with two-nucleon transfer processes between members of pairing rotational bands, making use of simple BCS (constant matrix elements) or of many-body (Nambu-Gorkov (NG), nuclear field theory (NFT)) spectroscopic amplitudes, is not immediately obvious. Restoration of spontaneous symmetry breaking and associated emergent generalised rigidity in gauge space provides the answer, and points to a new emergence: a physical sum rule resulting from the intertwining of structure and reaction processes and closely connected with the central role induced pairing interaction plays in structure together with the fact that successive transfer dominates Cooper pair tunnelling.
Ideal strength of two-dimensional stanene may reach or exceed Griffith strength estimate

description: The ideal strength is the maximum stress a material can withstand, and it is an important intrinsic property for structural applications. Griffith strength limit ~E/9 is the best known upper bound of this property for a material loaded in tension. Here we report that stanene, a recently fabricated two-dimensional material, could approach and possibly exceed this limit from a theoretical perspective. Utilizing first-principles density functional theory, we investigated the nonlinear elastic behavior of stanene and found that its strength could reach ~E/7.4 under uniaxial tension in both armchair and zigzag directions without incurring phonon instability or mechanical failure. The unique mechanical properties of stanene are further appreciated by comparisons with two other Group-IV 2D materials, graphene and silicene.

description: We consider the Aharonov-Bohm effect on entanglement entropy for one interval in (1+1) dimensional conformal field theory on a one dimensional ring. The magnetic field is confined inside the ring, i.e. there is a Wilson loop on the ring. The Aharonov-Bohm phase factor which is proportional to the Wilson loop is represented as insertion of twist operators. We compute exactly the Renyi entropy from a four point function of twist operators in a free charged scalar field.
