description: In this work, we study the t-J model using a two-pole approximation within the composite operator method. We choose a basis of two composite operators -- the constrained electrons and their spin-fluctuation dressing -- and approximate their currents in order to compute the corresponding Green's functions. We exploit the algebraic constraints obeyed by the basis operators to close a set of self-consistent equations that is numerically solved. This allows to determine the physical parameters of the system such as the spin-spin correlation function and the kinetic energy. Our results are compared to those of an exact numerical method on a finite system to asses their reliability. Indeed, a very good agreement is achieved through a far less numerically demanding and a more versatile procedure. We show that by increasing the hole doping, anti-ferromagnetic correlations are replaced by ferromagnetic ones. The behavior on changing temperature and exchange integral is also studied and reported.

description: Spectropolarimetric reconstructions of the photospheric vector magnetic field are intrinsically limited by the so-called 180$^\circ$ ambiguity in the orientation of the transverse component. The successful launch and operation of Solar Orbiter has made the removal of the 180$^\circ$ ambiguity possible using solely observations obtained from two different vantage points. While the exploitation of such a possibility is straightforward in principle, it is less so in practice and it is therefore important to assess the accuracy and limitations, as a function of both the satellites orbits and measurement principles. In this work we present a stereoscopic disambiguation method (SDM) and discuss a thorough testing of its accuracy in applications to modeled active regions and quiet Sun observations. In a first series of tests, we employ magnetograms extracted from three different numerical simulations as test fields, and model observations of the magnetograms from different angles and distances. In these more idealized tests, the SDM is proven to to reach a 100% disambiguation accuracy when applied to moderately-to-well resolved fields. Even in the case of disambiguation of quiet Sun magnetograms with significant under-resolved scale, the SDM provides an accuracy between 82% and 98% depending on the field strength. The accuracy of the SDM is found to be mostly sensitive to the variable resolution of Solar Orbiter on its highly elliptic orbit, as well as to the intrinsic scale of the observed field. Finally, as a more realistic test, we consider magnetograms that are obtained using a radiative transfer inversion code and the SOPHISM instrument simulator applied to a 3D simulation of a pore, and present a preliminary discussion of the effect of the viewing angle on the observed field.

The Smart Wizard: Literature as a Lie, Theatre as a Rite (Giorgio Manganelli reads W.B. Yeats)
Creators: name: Luppi, Fabio
Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2013

description: The present essay investigates the relationship between the literary critic and writer Giorgio Manganelli, and W.B. Yeats. It is composed of two parts. The first deals with the idea of literature as a lie presented by Manganelli in his famous book collecting several essays on literary figures, La letteratura come menzogna (1985) and focuses on the articles written by Manganelli on Yeats over the years, explaining why the Italian writer was so fond of the Irish poet. Whereas in his first essays Manganelli proposed an introductory reading of Yeats, though centered on peculiar aspects of his poetry, later he concentrated on the idea which lies beneath the conception of Yeats’s poetics. Yeats’s poetry suggests to Manganelli the deep meaning of literature providing the most correct interpretation for all fictional work. In the second part of this essay focus shifts from literature in generalf to the idea of theatre expressed by the two writers. The attempt is to find the similarities between their conceptions of the theatrical work and their experimental plays, considering Yeats’s plays as a fundamental model for Manganelli’s theatre. The keyword which joins together their poetics is the return to the rituals of the primitive stage and the ceremonial aspects of ancient times.

description: In this paper, we study the greybody factors (GFs) for fermions with different spins and bosons in the regular black hole (BH) predicted by a non-minimal Einstein-Yang-Mills (EYM) theory. We investigate the effect of magnetic charge on effective potentials and GFs. For this purpose, we consider the Dirac and Rarita-Schwinger, as well as Klein-Gordon equations. First, we study the Dirac equation in curved spacetime for massive and massless spin-1/2 fermions. We then separate the Dirac equation into sets of radial and angular equations. Using the analytical solution of the angular equation, the Schrödinger-like wave equations with potentials are derived by decoupling the radial wave equations via the tortoise coordinate. We also consider the Rarita-Schwinger equation for massless spin-3/2 fermions and derive the one-dimensional Schrödinger wave equation with gauge-invariant effective potential. For bosons, we study the Klein-Gordon equation in the regular non-minimal EYM BH. Afterward, semi-analytic methods were used to calculate the fermionic and bosonic GFs. Finally, we discuss the graphical behavior of the obtained effective potentials and bounds on the GFs. According to graphs, the GF is highly influenced by the potential's shape, which is determined by the parameterization of the model. This is in line with quantum theory.

description: This essay provides a critical analysis of Don DeLillo’s novel The Body Artist and Samuel Beckett’s work for television Ghost Trio. In particular it analyses the representation of time and its perception in both these works, highlighting some shared aesthetic modalities such as their attempt to depict duration through a poetics of slow motion. The essay also foregrounds how both these works give narrative form to Merleau-Ponty’s understanding of ‘time as its perception’.

Student attitude and achievement in freshman physics, as related to stated student occupational choice : a multivariate approach
Creators: name: Fox, Roger F.
Publisher: name: University of British Columbia
Year: 2010

description: Knowledge of how different vocation-oriented groups of students respond to the classroom environment is a serious concern of an instructor in a first year college physics course -- especially those who accept the responsibility of facilitating the resolution of vocational choice determination. Knowledge about the nature of the instructor's class -- in terms of how they respond to various aspects of the teaching-learning situation -- has interpretative value in making decisions about special instructional provisions for the groups. This thesis was an attempt to provide information about the nature of the differences between vocation-oriented groups of students, in terms of selected dependent variables, important to the instructor of a first year college physics course. The data for the study was gathered from one class of a Physics 110 course offered at the University of British Columbia. Students in the class were divided into three groups based on vocational choice. Each of these groups were further subdivided in terms of the amount of high-school physics experience. Nineteen dependent variables were classified into three categories: (a) Antecedent -- Variables which provided information on a student's general academic ability, and his competence in Science subjects at the high-school level, (b) Cognitive -- Variables which provided information on student achievement during the year in Physics 110, and (c) Affective -- Variables providing information about a student's attitude towards concepts related to science in general and physics in particular. The data gathered was analysed first by a one-way multivariate analysis of variance. This analysis showed that there was a statistical significant difference between vocation-oriented group centroids on the dependent variables taken all at a time. The analysis was carried further to determine the nature of these group differences through a discriminant analysis. The discriminant analysis produced two significant discriminant functions which provided information on the variables that contributed most to differentiating between the groups along each function. The overall conclusion that was suggested is that only those students who were required to take just one year of college physics were clearly distinguished from the other vocation oriented groups. The major distinction between these groups being academic ability. Years of schooling in a subject area was also an important distinguishing factor for instructional purposes, but this factor did not discriminate between the various vocation-oriented groups.
Effect of evolutionary physical constants on type-1a supernova luminosity

description: Type 1a supernovae, SNeIa, are used as standard candles in cosmology for determining the distances of the galaxies harboring them. We show that the luminosity of an SNIa depends on its distance from us when physical constants (the speed of light $c$, the gravitational constant $G$, and the Planck constant $h$) are permitted to evolve. It is because the Chandrasekhar mass of the white dwarf that explodes to create SNIa depends on the values of the constants at the epoch the SNIa is formed. We show that the SNeIa luminosities were up to about four times higher in the past than they are now. Thus, the luminosity distance estimation of the earliest SNeIa could be off by up to a factor of two. Cosmological parameters, determined with this correction applied to the redshift vs. distance modulus database (Pantheon SNeIa), are not very different from those from the standard $Λ$CDM model without this correction, except for the dark-energy density and the curvature energy density; the latter increases at the cost of the former. Variations of the constants are given by $\dot{G}/G=3.90(\pm 0.04)\times 10^{-10} yr^{-1} $ and $\dot{c}/c=\dot{h}/h=1.30(\pm 0.01)\times 10^{-10} yr^{-1} $ at present. These variations are valid only when $G$, $c$, and $h$ are permitted to vary concurrently rather than individually.

The targum (1971:May 3 - 1971:May 14)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1971

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We report on the fabrication and characterization of a few-electron quantum dot controlled by a single gate electrode. Our device has a double-quantum-well design, in which the doping controls the occupancy of the lower well while the upper well remains empty under the free surface. A small air-bridged gate contacts the surface, and is positively biased to draw laterally confined electrons into the upper well. Electrons tunneling between this accumulation-mode dot and the lower well are detected using a quantum point contact (QPC), located slightly offset from the dot gate. The charge state of the dot is measured by monitoring the differential transconductance of the QPC near pinch-off. Addition spectra starting with N=0 were observed as a function of gate voltage. DC sensitivity to single electrons was determined to be as high as 8.6%, resulting in a signal-to-noise ratio of ~9:1 with an equivalent noise bandwidth of 12.1 kHz. Analysis of random telegraph signals associated with the zero to one electron transition allowed a measurement of the lifetimes for the filled and empty states of the one-electron dot: 0.38 ms and 0.22 ms, respectively, for a device with a 10 nm AlInAs tunnel barrier between the two wells.

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Magnetic helicity plays a tremendously important role when it is different from zero on average. Most notably, it leads to the phenomenon of an inverse cascade. Here, we consider decaying magnetohydrodynamic (MHD) turbulence as well as some less common examples of magnetic evolution under the Hall effect and ambipolar diffusion, as well as cases in which the magnetic field evolution is constrained by the presence of an asymmetry in the number density of chiral fermions, whose spin is systematically either aligned or anti-aligned with its momentum. In all those cases, there is a new conserved quantity: the Hosking integral. We present quantitative scaling results for the magnetic integral scale as well as the magnetic energy density and its spectrum. We also compare with cases were a magnetic version of the Saffman integral is initially finite. Rotation in MHD turbulence tends to suppress nonlinearity and thereby also inverse cascading. Finally, the role of the Hosking and magnetic Saffman integrals in shell models of turbulence is examined.

description: In biology, information flows from the environment to the genome by the process of natural selection. But it has not been clear precisely what sort of information metric properly describes natural selection. Here, I show that Fisher information arises as the intrinsic metric of natural selection and evolutionary dynamics. Maximizing the amount of Fisher information about the environment captured by the population leads to Fisher's fundamental theorem of natural selection, the most profound statement about how natural selection influences evolutionary dynamics. I also show a relation between Fisher information and Shannon information (entropy) that may help to unify the correspondence between information and dynamics. Finally, I discuss possible connections between the fundamental role of Fisher information in statistics, biology, and other fields of science.

description: In this review, we outline the expected tests of gravity that will be achieved at cosmological scales in the upcoming decades. We focus mainly on constraints on phenomenologically parameterized deviations from general relativity, which allow to test gravity in a model-independent way, but also review some of the expected constraints obtained with more physically motivated approaches. After reviewing the state-of-the-art for such constraints, we outline the expected improvement that future cosmological surveys will achieve, focusing mainly on future large-scale structures and cosmic microwave background surveys but also looking into novel probes on the nature of gravity. We will also highlight the necessity of overcoming accuracy issues in our theoretical predictions, issues that become relevant due to the expected sensitivity of future experiments.

Sentence, phrase and pivotal word recall as related to sentence complexity, response mode, and practice
Creators: name: Mitchell, Diana Lee
Publisher: name: University of British Columbia
Year: 2010

description: The effects on sentence, phrase, and pivotal word recall of variations in mean depth, type, and length of sentences, response mode, and practice were studied with one hundred twenty-eight Grade Eleven students. The results provide substantial support for Martin and Roberts' (1966) listening-reproducing model of sentence processing. Verbatim recall of low mean depth sentences exceeded that of high mean depth sentences; pivotal words from phrases of the greatest mean depth were harder to recall than were their lower mean depth counterparts; and the analysis of phrase dependency measures indicated that left-to-right binary processing was taking place during the encoding and decoding of responses. In addition, the results provided partial confirmation of the notion of coding by transformational tags. Verbatim sentence recall was affected by the stimulus sentence's transformational type, but not in the predicted direction. Errors in sentence recall, however, were as was predicted: K > N, P, Q > NP, NQ, PQ > NPQ. Further, declarative sentences were recalled correctly more often than were interrogative, as was predicted from the coding hypothesis, but active and passive sentences were equally well recalled, and negative sentences were recalled better than affirmative sentences, neither of which result can be accounted for by the coding hypothesis. Mood, voice, and modality changes were found to have various effects on the recall of phrases and pivotal items, but often these effects were related to the lexical density of specific phrases. Pivotal words were observed to have performed an important function in early recall particularly, and this function was explained in terms of the memory for "gist" hypothesis (Reid, 1974). Sentence length interacted with mean depth and lexical density, a result which was felt to be an artifact resulting from incomplete orthogonality of these variables. The written response mode facilitated recall generally, as did practice, with practice resulting most noticeably in improved recall of all pivotal words, and of low mean depth and long sentences which were written rather than spoken.

description: The ferroelectric order and magnetic field induced effects observed in the spiral phase of MnWO4 are described theoretically. It is demonstrated explicitly that the Dzyaloshinskii-Moriya antisymmetric interactions contribute to the correlation between spins and electric dipoles in the incommensurate and commensurate ferroelectric phases of magnetic multiferroics. However, other single-site symmetric interactions are shown to be involved in the magnetoelectric process, suggesting the possible existence of an electric polarization originating from purely symmetric effects.

description: Quantum models for synchronously pumped type I optical parametric oscillators (SPOPO) are presented. The study of the dynamics of SPOPOs, which typically involves millions of coupled signal longitudinal modes, is significantly simplified when one considers the ?supermodes?, which are independent linear superpositions of all the signal modes diagonalizing the parametric interaction. In terms of these supermodes the SPOPO dynamics becomes that of about a hundred of independent, single mode degenerate OPOs, each of them being a squeezer. One derives a general expression for the squeezing spectrum measured in a balanced homodyne detection experiment, valid for any temporal shape of the local oscillator. Realistic cases are then studied using both analytical and numerical methods: the oscillation threshold is derived, and the spectral and temporal shapes of the squeezed supermodes are characterized.

description: We investigate the properties of dark energy halos in models with a nonminimal coupling in the dark sector. We show, using a quasistatic approximation, that a coupling of the mass of dark matter particles to a standard quintessence scalar field $ϕ$ generally leads to the formation of dark energy concentrations in and around compact dark matter objects. These are associated with regions where scalar field gradients are large and the dark energy equation of state parameter is close to $-1/3$. We find that the energy and radius of a dark energy halo are approximately given by $E_{\rm halo} \sim \boldsymbolβ^2 φ\, m$ and $r_{\rm halo} \sim \sqrt{\boldsymbolβ \,φ({R}/{H})}$, where $φ=Gm/(R c^2)$, $m$ and $R$ are, respectively, the mass and radius of the associated dark matter object, $\boldsymbolβ = -(8πG)^{-1/2} d \ln m/d ϕ$ is the nonminimal coupling strength parameter, $H$ is the Hubble parameter, $G$ is the gravitational constant, and $c$ is the speed of light in vacuum. We further show that current observational limits on $\boldsymbolβ$ over a wide redshift range lead to stringent constraints on $E_{\rm halo}/m$ and, therefore, on the impact of dark energy halos on the value of the dark energy equation of state parameter. We also briefly comment on potential backreaction effects that may be associated with the breakdown of the quasistatic approximation and determine the regions of parameter space where such a breakdown might be expected to occur.

description: Background: Emerging epidemiological data suggest that Hypertension (HTN) has become a significant public health challenge in sub-Saharan Africa. HTN in young adults is a problem lacking relevant attention because it is still erroneously considered a disease of the old. This study aimed to determine the prevalence of hypertension and its associated risk factors in undergraduate medical students at the University of Nigeria, Enugu Campus, Enugu State, Nigeria.

Methodology: This was a cross-sectional study conducted between March and April 2021. This study recruited 279 consenting medical students (136 males and 143 females) aged 18–35 years. They were administered with a structured questionnaire. Data on sociodemographic information and risk factors for hypertension were collected. Blood pressure, waist circumference, weight, height, and body mass index were measured using standard methods. All data collected were carried out following the Institutional ethical guidelines and that of the Helsinki as revised in 2000. Data were analyzed using IBM Statistical Package for Social Sciences version 25, and statistical tools employed include descriptive statistics and Chi tests. Results were recorded as mean standard deviation, and statistical significance was taken at p<0.05. 

Results: This present study has shown a prevalence rate of 19.93% for hypertension. Isolated diastolic hypertension constituted a greater burden with a prevalence of 13.65% than systolic Hypertension (0.74%) and systolic-diastolic Hypertension 5.4%. The prevalence of prehypertension was 48.7%, with a higher incidence observed in females (25.8%), individuals aged 21-25 years (26.4), and those with normal BMI (35.1%). A significant association was observed between the stage of hypertension and gender (p = 0.005), and age category (p = 0.037). Of the examined cohort, 7.75% were underweight, 16.5% overweight, and 2.2% obese. Notably, systolic, and diastolic blood pressure, weight, as well as waist circumference showed significant (p = 0.01, p = 0.007, p =0.01 and p<0.0001 respectively) increases concomitant with advancing age.

Conclusion: There is an increased prevalence of prehypertension and hypertension among young adults. This calls for a comprehensive national screening, public enlightenment, and targeted prevention programs that foster healthy lifestyle behaviours, physical activity, and healthy eating among students

Translating Others, Discovering Himself: Beckett as Translator

Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2011

description: This paper examines the work of Samuel Beckett in the light of his early work as a translator of the works of other writers.  In his translations for Negro: An Anthology (1934), the Anthology of Mexican Poetry (1958), or commissioned translations for journals such as “This Quarter”, early pre-figurings of Beckett’s own thematic and linguistic concerns abound.  Rarely viewed as more than acts of raising money for himself, Beckett’s acts of translation, examined chronologically, demonstrate a writer discovering his craft, and developing his unique voice, unencumbered by the expectations of originality.  This essay posits that Beckett’s works, with their distinctive voice and characterisation, owe much to the global perspective he gained through translating across cultural, continental divides, as well as experimenting with form, which became a staple of Beckett’s own work.  Without formal training or theoretical grounding in translation, Beckett utilises the act of translation as a means of finding himself, revisiting it as a means of shaping his own unique literary voice.

Prevalence and Predictors for use of Herbal medicine in the treatment of Infertility in a secondary Health facility in South-South Nigeria
Creators: name: Maduka, Ngozi Roy
name: Okubor, Onyekachukwu Paul
Publisher: name: Nigerian Medical Journal
Year: 2024

description: Background: Infertility is one of the major medical problems seen in the Gynaecology clinic. Herbal medicine (HM) has become one the of treatment options used to circumvent infertility problems. This study aims to explore the prevalence and predictors for HM use in the management of infertility in our region. 

Methodology: The method used was a cross-sectional study of 117 women attending the infertility clinic at Central Hospital Agbor, Delta State, Nigeria. The interviewer administered a questionnaire comprised of socio-demographic characteristics, infertility-related aspects and information on herbal medicine usage. The main outcome measure was the Prevalence of HM use for infertility treatment and the possible predictors. Analysis was done using SPSS version 22.

Results: The mean age of participants was 34.1 with a standard deviation of 6.66 years. The minimum age of participants was 23 years and while maximum age was 48 years. The prevalence of HM use was 79.9%. The factors that were significantly associated with the use of HM were marital status (p 0.033), history of primary infertility (0.026) and having used HM for the management of other ailments (0.000). Women who were married and having fertility issues were more likely to seek alternative methods like the use of HM.

Conclusion: The prevalence of use of HM among participants attending the fertility clinic was high at 79.9%. We recommend that health professionals should enquire about the use of HM as this may help in educating the patients about the health risks of using HM. There is a need to explore the potential benefits and risks of HM use.

description: The work presents a solution for completely decentralized data management systems in geographically distributed environments with administratively unrelated or loosely related user groups and in conditions of partial or complete lack of trust between them. The solution is based on the integration of blockchain technology, smart contracts and provenance metadata driven data management. Architecture, operation principles and algorithms developed provides fault-tolerant, safe and reliable management of provenance metadata, control of operations with data files, as well as resource access management in collaborative distributed computing systems. The latter refer to distributed systems formed by combining into a single pool of computer resources of various organizations (institutions) to work together in the framework of some project.

Una dinamica dialogica per la nascita delle Scienze bioeducative

description: The author gives a brief background on the relationship between education and biology. It identifies, well, a new area of research that reinterprets, in the plurality of meanings that affect modifiability biological and environmental variability, the potential for individual learning. Dewey considers crucial the role of individual and especially of past experience: the ideas we have in mind and processed depends largely on the experience already had in the same manner by the individual and the reflective process depend on the “dress of thought “that every individual has accrued through their own past experience. The author focuses on the reflection of his own encounter between biological and social aspects in the learning process.

description: We argue that macroeconomic performance shapes the evasion of presidential term limits in two ways: first, by influencing the decision to extend, abolish, or simply avoid term limits, and second, by shaping the choice to rely on judicial decisions, legislative action, or a public referendum for implementation. Drawing on the theory of retrospective economic voting, we argue that strong economic performance increases the likelihood of evasion types and methods subject to voter participation in the process, such as extending and abolishing term limits and employing public referendum. Weak economic performance, by contrast, encourages presidents to avoid term limits altogether or adopt evasion methods that allow them to mitigate public scrutiny. We collect new data that codes details about the methods used in more than 80 instances of presidential term limit violations globally and find robust empirical support for these claims. We find particularly strong evidence that increases in unemployment are associated with a higher risk of avoidance, since this strategy allows presidents to stay in office while evading punishment at the polls. Faster rates of economic growth, by contrast, are associated with greater risk of extending and abolishing term limits, and the use of public referenda that legitimate these changes.

description: Ferroelectricity (Valasek, J. Phys. Rev. 1921, 17, 475) - a spontaneous formation of electric polarisation - is a solid state phenomenon, usually, associated with ionic compounds or complex materials. Here we show that, atypically for elemental solids, few-layer graphenes can host an equilibrium out-of-plane electric polarisation, switchable by sliding the constituent graphene sheets. The systems hosting such effect include mixed-stacking tetralayers and thicker (5-9 layers) rhombohedral graphitic films with a twin boundary in the middle of a flake. The predicted electric polarisation would also appear in marginally (small-angle) twisted few-layer flakes, where lattice reconstruction would give rise to networks of mesoscale domains with alternating value and sign of out-of-plane polarisation.

Multiflavor QCD* on R_3 x S_1: Studying Transition From Abelian to Non-Abelian Confinement

description: The center-stabilized multiflavor QCD* theories formulated on R_3 x S_1 exhibit both Abelian and non-Abelian confinement as a function of the S_1 radius, similar to the Seiberg-Witten theory as a function of the mass deformation parameter. For sufficiently small number of flavors and small r(S_1), we show occurence of a mass gap in gauge fluctuations, and linear confinement. This is a regime of confinement without continuous chiral symmetry breaking (χSB). Unlike one-flavor theories where there is no phase transition in r(S_1), the multiflavor theories possess a single phase transition associated with breaking of the continuous chiral symmetry. We conjecture that the scale of the χSB is parametrically tied up with the scale of Abelian to non-Abelian confinement transition.

description: The VERITAS gamma-ray telescope array has been operating since 2007 and has been equipped with Hamamatsu R10560-100-20 PMTs since 2012. A decision to continue operations into the mid 2020s was taken in 2019 so the question of whether the PMTs would need replacing became important and a study was initiated. We present results from scanning two groups of 20 Hamamatsu R10560-100-20 PMTs with an LED flasher. One group comprised five PMTs from each of the four VERITAS telescopes and the other was made up of 20 PMTs of the same type, and date of manufacture, that had never been used. We measured three test variables related to gains and high-voltage response and found that there were no significant differences between the two groups. This indicates that there has been little ageing in the PMTs that have been used on the telescopes and that replacement is unnecessary.

description: Local excitations as carriers of quantum information spread out in the system in ways governed by the underlying interaction and symmetry. Understanding this phenomenon, also called quantum scrambling, is a prerequisite for employing interacting systems for quantum information processing. The character and direction dependence of quantum scrambling can be inferred from the out-of-time-ordered commutators (OTOCs) containing information on correlation buildup and entanglement spreading. Employing OTOC, we study and quantify the directionality of quantum information propagation in oxide-based helical spin systems hosting a spin-driven ferroelectric order. In these systems, magnetoelectricity permits the spin dynamics and associated information content to be controlled by an electric field coupled to the emergent ferroelectric order. We show that topologically nontrivial quantum phases, such as chiral or helical spin ordering, allows for electric-field controlled anisotropic scrambling and a direction-dependent buildup of quantum correlations. Based on general symmetry considerations, we find that starting from a pure state (e.g., the ground state) or a finite temperature state is essential for observing directional asymmetry in scrambling. In the systematic numerical studies of OTOC, we quantify the directional asymmetry of the scrambling and verify the conjectured form of the OTOC around the ballistic wavefront. The obtained direction-dependent butterfly velocity $v_{\mathrm{B}}(\mathbf{n})$ provides information on the speed of the ballistic wavefront. In general, our calculations show an early-time power-law behavior of OTOC, as expected from an analytic expansion for small times. The long-time behavior of OTOC reveals the importance of (non-)integrability of the underlying Hamiltonian as well as the implications of conserved quantities such as the $z$-projection of the total spin.
