description: "The Future of Supersonic Flight"
Supersonic travel is a ubiquitous mode of transport that has been widely recognised since the 1960s. Humans rely on supersonic flights to traverse across vast landmasses in an efficient time. Not until recently, the future of aviation has been rendered uncertain due to the unforeseen pandemic. Nevertheless, this denotes a transformative period of the aviation industry, with the emergence of disruptive technologies and pivotal design features, in lieu of grounded flights. In this essay, we will primarily discuss about the background and renaissance of commercial supersonic transport, its prevailing challenges, proposed novel solutions and technologies, and the future sustainability.

description: The COMPTEL experiment on CGRO observed the gamma-ray sky at energies from 0.75 MeV to 30 MeV between April 1991 and June 2000. COMPTEL detected many gamma-ray sources, among them an unidentified one labeled GRO J1823-12, which is positionally consistent with the prominent high-mass X-ray binary LS 5039. Because LS 5039 was established as gamma-ray emitter during recent years, whose gamma-radiation radiation is modulated along its binary orbit, we reanalysed the COMPTEL data of GRO J1823-12 including an orbital resolved analysis. We find a significant MeV source, showing evidence for a modulated MeV flux corresponding to the orbital period of LS 5039 of about 3.9 days. We show that its MeV emission is stronger at the orbital part around the inferior conjuction than at the part of the superior conjunction, being in phase with X-rays and TeV gamma-rays, however being in anti-phase with GeV gamma-rays. We conclude that the COMPTEL source GRO J1823-12 is the counterpart of the microquasar candidate LS 5039, at least for the majority of its MeV emission. The COMPTEL fluxes, put into multifrequency perspective, provide new constraints on the modelling of the high-energy emission of LS 5039.

description: Objective: To increase the nutritional value of donations given by donor organizations to the Food Bank based on a Red-Yellow-Green (RYG) scale. Background: Food banks have been planted across the Southeastern Virginia region to help with the prevalent issue of food insecurity. The food bank receives various food donations. The goal, however, is to implement education to the donor organizations to improve the nutritional value of the donations based on the Red-Yellow-Green scale. Participants and Methods: A Quasi-Experimental Before-and-After design across multiple groups will be used. Consistent donor groups will be selected for the intervention and baseline donations will be monitored for a month based on health value. After the first month, the one-week education intervention will be implemented. Donations from the donor organizations will, then, be monitored for an additional month. Finally, the nutritional value of the donations will be assessed based on the RYG scale. Analysis: The data will be analyzed using the central tendency method of descriptive statistics. A paired T-test will determine whether there was a statistical difference pre- and post-intervention, which will infer the impact of nutrition education on the quality of donations presented by the organizations. Results: There is an expected increase in the amount of green donations and decrease in the amount of red donations received by donor organizations. Limitations: Limitations of this study include the trial period, season, convenience of items, selected sample size, and finances.
Out-group hate in the UK: Insights from race and religious hate crime representations and attitudes towards immigrants
Creators: name: Dave, Ravi
Publisher: name: University of Lincoln
Year: 2023

description: Hate crimes have become a common problem in the United Kingdom (UK), especially following the European Union (EU) referendum and the BREXIT vote in June 2016. Consequently, hate crimes have received a great deal of attention in the recent past, with increasing discussions tailored around the need to accurately record and investigate these crimes. However, the field of hate crimes is complicated by inaccuracies in reporting and recording of these crimes, in addition to there being no clear understanding of how hate crimes are constructed by the general public and the intersection between the public perceptions and hate crime scholarship. Hate crime policing has advocated the protection of five-strands of people that are most likely to be recipients of such victimisation, while statistics suggest that two of the strands, race and religion, account for 80% of hate crime in the UK. Due to the frequent occurrence of race and religious hate crimes in the UK, this research aimed to investigate the general public and cultural perceptions and understandings of race and religious hate crime, in particular. Using a mixed-method design, this thesis conducted three empirical studies to investigate the facets of race and religious hate crimes in the UK. Study 1 carried out a cultural analysis of hate crime by examining newspaper articles to extract the key attributes evident in the reporting of race and religious hate crimes. A total of 22 key variables were seen to present when reporting such crimes, so for the general public these maybe the trigger for, and ideas by which, they come to define and understand an event as possibly being a hate crime. Study 2 looked more specifically at this perception and understanding of race and religious hate crimes amongst the general public by using a ‘storycompletion task’. The results suggested a variety of themes by which people might understand and demarcate race and religious hate crime; these are key social-psychological factors that need to be considered in terms of hate crime practice and policy. Finally, Study 3 evaluated the underlying social-psychological factors that may contribute to negative attitudes towards out-groups, a well-established finding in previous literature and evident in study two, that ‘othering’ and being seen as an out-group can be the basis of hate crime. The results suggested that people who are high on ethnocentrism are significantly more likely to show prejudice towards immigrants. In conclusion, the thesis highlighted that ‘othering’ individuals based on prejudicial attitudes can lead to hate crimes, therefore it is proposed that education on ethnic differences and early interventions to reduce prejudice (e.g. incorporating discussions of ethnicity in school curriculums), may be beneficial in reducing overall prejudice amongst the general public, which in-turn would help reduce hate crimes.

description: We present first-principles calculations of silicene/graphene and germanene/graphene bilayers. Various supercell models are constructed in the calculations in order to reduce the strain of the lattice-mismatched bilayer systems. Our energetics analysis and electronic structure results suggest that graphene can be used as a substrate to synthesize monolayer silicene and germanene. Multiple phases of single crystalline silicene and germanene with different orientations relative to the substrate could coexist at room temperature. The weak interaction between the overlayer and the substrate preserves the low-buckled structure of silicene and germanene, as well as their linear energy bands. The gap induced by breaking the sublattice symmetry in silicene on graphene can be up to 57 meV.

description: This thesis explores the positionality of women in ancient Athenian culture through the context of funerary engagement. The research examines the evolution of female identity in grave reliefs and how ideals were instilled and perpetuated in society. By comprehensively reviewing influential voices of ancient Athens that contributed to discussions surrounding women and their positionalities in ancient Athens, historically significant laws and legislation pertaining to funeral rites, an investigation of grave stelae manufacturing, before a final analysis of crafted grave stelae representing women at different life stages, this thesis aims to holistically investigate the ways in which women in ancient Athens were memorialized and how this affected the production of social ideology surrounding female identity. This research aims to contribute to a richer understanding of the ancient Athenian social landscape during the Classical period to better comprehend the production of social ideology. By examining the interplay between socio-political factors and individual agency, valuable insights into the complex dynamics and underlying forces that shaped the societal perceptions and roles of women in ancient Athens can be better understood.
Animal-Assisted Interventions in Special Needs Schools: What Works?

description: The present research set out to answer the question of what impact does a dog-assisted intervention have on children with special educational needs and if there are benefits, how long do they last for. The project was underpinned by previous research which for well over 30 years has indicated many benefits (Friesen, 2010; Fine, 2015). In addition, theories supporting the beneficial effects of animals such as Biophilia Hypothesis (Wilson, 1984), Attachment (Bowlby, 1969), Social Buffer (McNicholas & Collis, 2006) and Biopsychosocial Model (Engel, 1981) were also discussed. Literature reviews in the area of Animal-Assisted Interventions (AAIs) have established the lack of scientific rigour and consistency in the literature (e.g. O’Haire, 2013; O’Haire, 2017 Brelsford, Meints, Gee & Pfeffer, 2017), which this thesis set out to address. A Randomised Control Trial (RCT) design was employed with three conditions: dog intervention, relaxation intervention and no-treatment control group. The interventions were provided either as one-to-one or in a group setting. Measures were taken on academic factors (cognition and language) and well as physiological (cortisol) socioemotional (anxiety, self-esteem) and behavioural (behaviour at school and home, empathizing and systemizing) factors. The project included any 8-10-year-old children (N=157) who attended the special educational needs schools taking part, regardless of ability or diagnosis. The findings indicated that overall children benefitted from the dog and relaxation intervention but the benefits differed between tasks. There were also differences in progress between children of high and low ability. Some benefits lasted for 6 weeks after the intervention but were no longer present at 6-months or 1-year after the end of the intervention. This would indicate that children benefit from having a dog (or relaxation) intervention but the effects were not permanent so the intervention would need to be reintroduced. Future research needs to consider dosage of the AAI and exactly when the reintroduction needs to occur for optimum benefits.
The Prospects and Possibilities of Broadening the use of the Irish language in an English-medium post-primary school: A Case Study
Creators: name: Author, Unknown
Publisher: name: University of Lincoln
Year: 2023

description: The Irish language, classed as an endangered language, has been supported by successive Irish Government since the inception of the State in 1922. Yet, today, the high levels of support are not translated into daily usage and census data reveals a very low percentage admitting they use the language in their daily lives. This data is echoed in this study of Irish language knowledge and usage in a coeducational, English-medium, postprimary school in the West of Ireland. This single exploratory case study sought information from stakeholders about their attitudes and beliefs about the Irish language. Information was sought also about their perceptions of initiatives they envisaged would assist in broadening the use of Irish in school, as was their level of awareness of Governmental initiatives that support Irish in schools and in society.While positive sentiments were expressed about the language there was less evidence of this sentiment being translated into action unless there was sufficient support and scaffolding available. The Irish langauge was valued as a weak marker of Irish identity rather than as a communicative tool due to English being spoken by the community. This removed the necessity to speak Irish. In this community Irish is rarely used in the home and it is used more often when on holidays or working abroad. Due to the lack of urgency to learn the language stakeholders in this community interviewees called for Irish learning to be entertaining and fun. The apparent lack of ability to engage in more meaningful conversation was blamed on the Irish language syllabus, where there was a focus on literature and rote learning rather than on communicative skills. The Irish language was supported insofar as it was an opportunity to use Irish outside the classroom, but the support waned if extra work was involved. Participants in this study were unable to envisage how the proposed intervention would work. Evidently a lot of planning, headed by a committed team, is what was indicated to instil the promotion of the language.

description: In this paper we propose a new mechanism describing the initial spike of giant flares in the framework of the starquake model. We investigate the evolution of a plasma on a closed magnetic flux tube in the magnetosphere of a magnetar in the case of a sudden energy release and discuss the relationship with observations of giant flares. We perform one-dimensional numerical simulations of the relativistic magnetohydrodynamics in Schwarzschild geometry. We assume energy is injected at the footpoints of the loop by a hot star surface containing random perturbations of the transverse velocity. Alfvén waves are generated and propagate upward, accompanying very hot plasma that is also continuously heated by nonlinearly generated compressive waves. We find that the front edges of the fireball regions collide at the top of the tube with their symmetrically launched counterparts. This collision results in an energy release which can describe the light curve of initial spikes of giant flares.

description: A recently discovered magnetic semiconductor Ba$_{1-x}$K$_{x}$(Zn$_{1-y}$Mn$_{y}$)$_2$As$_{2}$, with its decoupled spin and charge doping, provides a unique opportunity to elucidate the microscopic origin of the magnetic interaction and ordering in dilute magnetic semiconductors (DMS). We show that (i) the conventional density functional theory accurately describes this material, and (ii) the magnetic interaction emerges from the competition of the short-range superexchange and the longer-range spin-spin interaction mediated by the itinerant As holes. The latter can be viewed as a high-doping extrapolation of with the Schrieffer-Wolff $p-d$ interaction representing an effective Hund's rule coupling, $J_{H}^{\text{eff}}$. The key difference between the classical double exchange and the actual interaction in DMS is that an effective $J_{H}^{\text{eff}}$, as opposed to the standard Hund's coupling $J_{H}$, depends on the Mn $d-$band position with respect to the Fermi level, and thus allows tuning of the magnetic interactions. The physical picture revealed for this transparent system may also be applicable to more complicated DMS systems.

description: For an elastic system that is non-conservative but autonomous, subjected for example to time-independent loading by a steadily flowing fluid (air or water), a dangerous bifurcation, such as a sub-critical bifurcation, or a cyclic fold, will trigger a dynamic jump to one or more remote stable attractors. When there is more than one candidate attractor, the one onto which the structure settles can then be indeterminate, being sensitive to infinitesimally small variations in starting conditions or parameters. In this paper we develop and study an archetypal model to explore the nonlinear dynamic interactions between galloping at an incipient sub-critical Hopf bifurcation of a structure with shell-like buckling behaviour that is gravity-loaded to approach a sub-critical pitch-fork bifurcation. For the fluid forces, we draw on the aerodynamic coefficients determined experimentally by Novak for the flow around a bluff body of rectangular cross-section. Meanwhile, for the structural component, we consider a variant of the propped-cantilever model that is widely used to illustrate the sub-critical pitchfork: within this model a symmetry-breaking imperfection makes the behaviour generic. The compound bifurcation corresponding to simultaneous galloping and buckling is the so-called Takens-Bodganov Cusp. We make a full unfolding of this codimension-3 bifurcation for our archetypal model to explore the adjacent phase-space topologies and their indeterminacies.

description: A Bose-Einstein condensate trapped in a double-well potential, where atoms are incoupled to one side and extracted from the other, can in the mean-field limit be described by the nonlinear Gross-Pitaevskii equation (GPE) with a $\mathcal{PT}$ symmetric external potential. If the strength of the in- and outcoupling is increased two $\mathcal{PT}$ broken states bifurcate from the $\mathcal{PT}$ symmetric ground state. At this bifurcation point a stability change of the ground state is expected. However, it is observed that this stability change does not occur exactly at the bifurcation but at a slightly different strength of the in-/outcoupling effect. We investigate a Bose-Einstein condensate in a $\mathcal{PT}$ symmetric double-$δ$ potential and calculate the stationary states. The ground state's stability is analysed by means of the Bogoliubov-de Gennes equations and it is shown that the difference in the strength of the in-/outcoupling between the bifurcation and the stability change can be completely explained by the norm-dependency of the nonlinear term in the Gross-Pitaevskii equation.

title:  Ideological Analysis of Colorblindness in Get Out
Creators: name: Goldstein, Danielle
Publisher: name: Old Dominion University Libraries
Year: 2019

description: This ideological analysis of the horror film, Get Out, directed by Jordan Peele investigates three major ideological aspects that are poignant to the film. The main ideology that will be examined is “colorblindness” also known as colorblind racism, which is the belief or attitude that denying the existence of race will cure racism and achieve racial equality. The two other sub-ideologies that will be examined are multicultural racism and post-racism, as they are both facets of colorblindness and work together to reinforce one another in society. Colorblindness is apparent in the film’s dialogue that reveal attitudes regarding interracial dating and how the characters in the film are not only blind to the challenges of being black in America, but how they are also ignorant to their own whiteness. Colorblind discourse uses race-neutral language which is another way colorblind ideology is manifested throughout the film. This analysis utilizes transcriptions and screenshot images from the film as a means of exposing the scenes in which these ideologies are salient. The structure of this paper is organized in six different parts. Part 1 gives a description of the ideological categories and subcategories. Part 2 is a description and brief summary of the ideological site. Part 3 consists of results and prose description of results, which is separated in sections relevant to their respective ideologies. Part 4 details the interpretations and findings. The overall conclusions can be found in Part 5. Lastly, Part 6 describes the benefits, challenges, and limitations of this analysis.

description: In today VLSI system design, power consumption is gaining more attention as compared to performance and area. This is due to battery life in portable devices and operating frequency of the design. Power consumption mainly consists of static power, dynamic power, leakage power and short circuit power. Dynamic power is dominant among all which depends on many factors viz. power supply, load capacitance and frequency. Switching activity also affects dynamic power consumption of bus which is determined by calculating the number of bit transitions on bus. The purpose of this paper is to design a bit transition counter which can be used to calculate the switching activity of the circuit nodes. The novel feature is that it can be inserted at any node of the circuit, thus helpful for calculating power consumption of bus.

Discussions and problems that are currently going on in this field are also mentioned, such as the separation of the scientific and humanistic disciplines (i.e. the two cultures problem). Suggestions based on contemporary philosophy are also reported. Finally, sky-gazing is proposed as the place where the two cultures could meet, since, taking Plato into account, sky-gazing could be considered the mom of the human knowledge, and of the scientific and humanistic disciplines.

description: We propose to create and detect opto-mechanical entanglement by storing one component of an entangled state of light in a mechanical resonator and then retrieving it. Using micro-macro entanglement of light as recently demonstrated experimentally, one can then create opto-mechanical entangled states where the components of the superposition are macroscopically different. We apply this general approach to two-mode squeezed states where one mode has undergone a large displacement. Based on an analysis of the relevant experimental imperfections, the scheme appears feasible with current technology.

description: A major impediment to understanding star formation in massive star forming regions (MSFRs) is the absence of a reliable stellar chronometer to unravel their complex star formation histories. We present a new estimation of stellar ages using a new method that employs near-infrared (NIR) and X-ray photometry, AgeJX. Stellar masses are derived from X-ray luminosities using the Lx - Mass relation from the Taurus cloud. J-band luminosities are compared to mass-dependent pre-main-sequence evolutionary models to estimate ages. AgeJX is sensitive to a wide range of evolutionary stages, from disk-bearing stars embedded in a cloud to widely dispersed older pre-main sequence stars. The MYStIX (Massive Young Star-Forming Complex Study in Infrared and X-ray) project characterizes 20 OB-dominated MSFRs using X-ray, mid-infrared, and NIR catalogs. The AgeJX method has been applied to 5525 out of 31,784 MYStIX Probable Complex Members. We provide a homogeneous set of median ages for over a hundred subclusters in 15 MSFRs; median subcluster ages range between 0.5 Myr and 5 Myr. The important science result is the discovery of age gradients across MYStIX regions. The wide MSFR age distribution appears as spatially segregated structures with different ages. The AgeJX ages are youngest in obscured locations in molecular clouds, intermediate in revealed stellar clusters, and oldest in distributed populations. The NIR color index J-H, a surrogate measure of extinction, can serve as an approximate age predictor for young embedded clusters.

Supporting Children with Identified Speech, Language and Communication Needs at Two-Years-Old: Voices of Early Years Practitioners
Creators: name: Author, Unknown

description: Communication and language skills are essential for children to access learning opportunities and the curriculum. Existing research has highlighted that some children are living in England who start school without the necessary level of communication and language skills, to access the curriculum fully. Previous research has demonstrated that early identification of a speech, language and communication need (SLCN), is key to providing targeted interventions, to reduce the impact caused by these additional needs. However, changes within policy have created challenges for early years practitioners in identifying SLCN and providing support for those children. The current study explores the experiences of early years practitioners, as they navigate through the current statutory and non-statutory guidance, to identify, assess and support children’s development. The study utilised a narrative inquiry approach, through unstructured conversational interviews, to explore participants’ experiences. The fourteen interviews conducted involved fifteen participants from two geographical locations. A synthesised approach to analysis was taken, using both constructivist grounded theory and narrative framework approaches that provided an analytical framework. Findings suggest that the level of external support available to practitioners through education and health authorities varies according to location. Assessment arrangements through the primary tools used to assess children and the external pressure to collect data from assessments were discussed as a pressure point for participants, that at times, impacted on the reliability of the assessments conducted. These findings could add to the existing body of knowledge, by providing insight of assessment processes and the differences in assessments from setting to setting within geographical locations. The findings could raise questions on the validity of the assessment tool gathered from local and national data to create an overview of children’s developmental levels nationally.

description: Using our recently proposed Bethe-Salpeter $G_0W_0$ formulation, we explore the optical absorption spectra of fullerene (C$_{60}$) near coinage metal surfaces (Cu, Ag, and Au). We pay special attention to how the surface plasmon $ω_S$ influences the optical activity of fullerene. We find the lower energy fullerene excitons at 3.77 and 4.8 eV only weakly interact with the surface plasmon. However, we find the surface plasmon strongly interacts with the most intense fullerene $π$ exciton, i.e.\ the dipolar mode at $\hbarω_+\approx$ 6.5 eV, and the quadrupolar mode at $\hbarω_-\approx$ 6.8 eV. When fullerene is close to a copper surface ($z_0\approx$ 5.3 Å) the dipolar mode $ω_+$ and "localized" surface plasmons in the molecule/surface interface hybridize to form two coupled modes which both absorb light. As a result, the molecule gains an additional optically active mode. Moreover, in resonance, when $ω_S\approxω_\pm$, the strong interaction with the surface plasmon destroys the $ω_-$ quadrupolar character and it becomes an optically active mode. In this case the molecule gains two additional very intense optically active modes. Further, we find this resonance condition, $ω_S \approx ω_\pm$, is satisfied by silver and gold metal surfaces.

description: The Casimir-Polder and van der Waals interaction energy of an atom with infinitely thin sphere with finite conductivity is investigated in the framework of the hydrodynamic approach. We put the sphere into spherical cavity inside the infinite dielectric media, then calculate the energy of vacuum fluctuations in the context of the zeta-function approach. The energy for a single atom is obtained by rarefying media. The Casimir-Polder expression for an atom and plate is recovered in the limit of the infinite radius of the sphere. Assuming a finite radius of the sphere, the interaction energy of an atom falls down monotonic as third power of distance between atom and sphere for short distance and as seventh power for large distance from the sphere.

description: We explore the link between data representation and soft errors in dot products. We present an analytic model for the absolute error introduced should a soft error corrupt a bit in an IEEE-754 floating-point number. We show how this finding relates to the fundamental linear algebra concepts of normalization and matrix equilibration. We present a case study illustrating that the probability of experiencing a large error in a dot product is minimized when both vectors are normalized. Furthermore, when data is normalized we show that the absolute error is less than one or very large, which allows us to detect large errors. We demonstrate how this finding can be used by instrumenting the GMRES iterative solver. We count all possible errors that can be introduced through faults in arithmetic in the computationally intensive orthogonalization phase, and show that when scaling is used the absolute error can be bounded above by one.
Executive or Experience: Investigating the Role Executive Function Plays in Driving

description: Objective – Road traffic collisions (RTCs) are one of the leading causes of serious injury and fatality for adolescents and young adults. Human error is responsible for a large proportion of these RTCs in young drivers. Researchers have identified a number of contributory factors in human errors in RTCs. Executive Function (EF) is an area that is limited in research in relation to driving. This study examined the Behaviour Rating Inventory of Executive Function adult version (BRIEF-A) questionnaire, neuropsychological tests of EF as potential predictors of aberrant driving behaviour (i.e. atypical driving) and problematic driving outcomes in a driving simulator.Methods – 71 Young adult drivers (71 in part 1; 22 in part 2) completed an online self-report questionnaire consisting of the BRIEF-A, STAI-6, AQ-10 and the DBQ, four neuropsychological tests of EF, and three simulated drives that assess 11 problematic driving outcomes within a driving simulator (e.g. running red light, failure to signal and RTCs).Results – Higher levels of difficulty in executive skills were predictive of more aberrant driving behaviours. Neuropsychological tests did not find a predictive relationship between problematic driving outcomes however some relationships were found between variables. Other contributory factors were shown to predict small amounts of the variance within aberrant driving behaviours and overall EF score was a better predictor of singular components of EF.Conclusion – In summary findings indicated that the BRIEF-A showed significant association with aberrant behaviour in young adults. Predictive relationships were also found between these measures unlike, neuropsychological tests of EF and problematic driving outcomes in the driving simulator however a smaller sample size was used for the driving simulator section of the study. Future researchers should consider the self-reported examination of EF on individuals who have been charged with motoring offences also, high and low executive skills should be assessed against the reaction of drivers in hazardous driving scenarios. Driving safety officials should consider the affect EF has on driver training and rehabilitation.
Design of a 3D photonic band gap cavity in a diamond-like inverse woodpile photonic crystal

description: We theoretically investigate the design of cavities in a three-dimensional (3D) inverse woodpile photonic crystal. This class of cubic diamond-like crystals has a very broad photonic band gap and consists of two perpendicular arrays of pores with a rectangular structure. The point defect that acts as a cavity is centred on the intersection of two intersecting perpendicular pores with a radius that differs from the ones in the bulk of the crystal. We have performed supercell bandstructure calculations with up to $5 \times 5 \times 5$ unit cells. We find that up to five isolated and dispersionless bands appear within the 3D photonic band gap. For each isolated band, the electric-field energy is localized in a volume centred on the point defect, hence the point defect acts as a 3D photonic band gap cavity. The mode volume of the cavities resonances is as small as 0.8 $λ^{3}$ (resonance wavelength cubed), indicating a strong confinement of the light. By varying the radius of the defect pores we found that only donor-like resonances appear for smaller defect radius, whereas no acceptor-like resonances appear for greater defect radius. From a 3D plot of the distribution of the electric-field energy density we conclude that peaks of energy found in sharp edges situated at the point defect, similar to how electrons collect at such features. This is different from what is observed for cavities in non-inverted woodpile structures. Since inverse woodpile crystals can be fabricated from silicon by CMOS-compatible means, we project that single cavities and even cavity arrays can be realized, for wavelength ranges compatible with telecommunication windows in the near infrared.

description: Displaced single-photon entanglement is a simple form of optical entanglement, obtained by sending a photon on a beamsplitter and subsequently applying a displacement operation. We show that it can generate, through a momentum transfer in the pulsed regime, an optomechanical entangled state involving macroscopically distinct mechanical components, even if the optomechanical system operates in the single-photon weak coupling regime. We discuss the experimental feasibility of this approach and show that it might open up a way for testing unconventional decoherence models.

description: We derive the field correction to the Berry curvature of Bloch electrons, which can be traced back to a positional shift due to the interband mixing induced by external electromagnetic fields. The resulting semiclassical dynamics is accurate to second order in the fields, in the same form as before, provided that the wave packet energy is derived up to the same order. As applications, we discuss the orbital magnetoelectric polarizability and predict nonlinear anomalous Hall effects.
