Empowering the Next Generation of the Quantum Workforce
Creators: name: Araceli Venegas-Gómez
Publisher: name: Zenodo
Year: 2025

description: In this talk I will provide an overview of the quantum ecosystem, including public funding initiatives and companies around the world. Next, I will concentrate in the skills needed for quantum companies and the current job market situation. To finish, we will look at potential trends and career perspectives in the coming years.

Dr. Araceli Venegas-Gomez spent several years working for Airbus in Germany and France as an aerospace engineer, before falling in love with quantum mechanics. She then decided to follow her passion for physics, and moved to Scotland to pursue a PhD in quantum simulation at the University of Strathclyde. Following discussions with the different quantum stakeholders she had over the last years, Araceli identified the need to bridge the gap between businesses and academia, as well as to raise the quantum awareness to the general public. Continuing her work on outreach advocating quantum technologies, she was named the “quantum ambassador”, after winning the Optical Society Milton and Rosalind Chang Pivoting fellowship in 2019. Araceli founded her own company called QURECA (Quantum Resources and Careers) to create a link between the different stakeholders in the quantum community through a common language, and to generate global opportunities with quantum technologies. QURECA provides a range of professional services, business development, and the solution to the quantum workforce skills bottleneck: the first online platform for quantum training, to support individuals and businesses to be part of the quantum revolution.

description: We study the effect of a parallel magnetic field in a thin and small superconductor. The field suppresses superconductivity through Zeeman coupling while stabilizes the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state at high fields before superconductivity is destroyed. When the spatial period of FFLO state is comparable to the size of the superconductor, there is a strong commensuration effect, which modifies the superconducting phase diagram. We investigate the FFLO state and the phase diagram in the presence of strong commensuration effect both for the $s$-wave and $d$-wave superconductors using the Bogoliubov de Gennes equation, Green function approach, and Ginzburg-Landau theory. We found that the superconducting phase diagram is strongly modulated. Interestingly, there is re-entrance of superconductivity upon increasing the magnetic field. The commensuration effect of the FFLO state can be used to detect the FFLO state in experiments.

description: The study of elementary bosonic excitations is essential toward a complete description of quantum electronic solids. In this context, resonant inelastic X-ray scattering (RIXS) has recently risen to becoming a versatile probe of electronic excitations in strongly correlated electron systems. The nature of the radiation-matter interaction endows RIXS with the ability to resolve the charge, spin and orbital nature of individual excitations. However, this capability has been only marginally explored to date. Here, we demonstrate a systematic method for the extraction of the character of excitations as imprinted in the azimuthal dependence of the RIXS signal. Using this novel approach, we resolve the charge, spin, and orbital nature of elastic scattering, (para-)magnon/bimagnon modes, and higher energy dd excitations in magnetically-ordered and superconducting copper-oxide perovskites (Nd2CuO4 and YBa2Cu3O6.75). Our method derives from a direct application of scattering theory, enabling us to deconstruct the complex scattering tensor as a function of energy loss. In particular, we use the characteristic tensorial nature of each excitation to precisely and reliably disentangle the charge and spin contributions to the low energy RIXS spectrum. This procedure enables to separately track the evolution of spin and charge spectral distributions in cuprates with doping. Our results demonstrate a new capability that can be integrated into the RIXS toolset, and that promises to be widely applicable to materials with intertwined spin, orbital, and charge excitations.

description: We consider quantum systems which interact strongly with a rapidly varying environment and derive a Schrodinger-like equation which describes the time evolution of the average wave function. We show that the corresponding Hamiltonian can be taken to be Hermitian provided all states are rotated using an appropriate unitary transformation. The formalism is applied to a variety of systems and is compared and contrasted with related results describing stochastic resonances.

 Lithomelissa sp 1, Trubovitz et al., 2020, supplementary data 7.
 Remarks. This species has a compressed, asymmetrical cephalis, which is longer than it is wide. It differs from L. ehrenbergi (Pl. 15, Figs. 7A–C) in that it does not have an extended neck, and differs from L. mitra (Pl. 15, Figs. 4A – 6) in that cephalis is not round. The large, framed pores differentiate this species from L. alkonost n. sp. (Pl. 16, Figs. 1A – 7B) and L. sirin n. sp. (Pl. 17, Figs. 1 –11B). Thus, this species does not seem to fit in any of the species categories for far described, but here we leave it in open nomenclature until a better understanding of its variability can be reached.
 Material examined. 15 specimens observed from samples 321-1337A-16H- 6, 121–124cm (Late Miocene), 321-1337A-10H-2, 91–94cm (Early Pliocene), 321-1337A-7H- 6, 104–107cm (Early Pliocene), 321-1337A-6H-3, 29–32cm (Late Pliocene), 321-1337A-4H-2, 16–19cm (Middle Pleistocene), 321-1337A-3H- 2, 103–106cm (Middle Pleistocene), 321-1337A-2H-3, 76–79cm (Late Pleistocene).

Searching for the Origin of Flares in M dwarfs

description: We present an overview of K2 short cadence observations for 34 M dwarfs observed in Campaigns 1 - 9 which have spectral types between M0 - L1. All of the stars in our sample showed flares with the most energetic reaching $3\times10^{34}$ ergs. As previous studies have found, we find rapidly rotating stars tend to show more flares, with evidence for a decline in activity in stars with rotation periods longer than approximately 10 days. We determined the rotational phase of each flare and performed a simple statistical test on our sample to determine whether the phase distribution of the flares is random or if there is a preference for phase. We find, with the exception of one star which is in a known binary system, that none show a preference for the rotational phase of the flares. This is unexpected and all stars in our sample show flares at all rotational phases, suggesting these flares are not all originating from one dominant starspot on the surface of the stars. We outline three scenarios which could explain the lack of a correlation between the number of flares and the stellar rotation phase. In addition we also highlight preliminary observations of DP Cnc, observed in campaigns 16 and 18, and is one of the stars in our extended sample from K2 Campaigns 10 -18 which are still to be examined.

description: As notícias são “um meio altamente imprevisível”, as decisões sobre a cobertura noticiosa devem ser tomadas de forma rápida, a pressão do tempo deixa pouco espaço a elaboradas tomadas de decisão. Os jornalistas têm de dominar um espaço de autonomia considerável na seleção e construção da notícia e perceber que só se podem obter reações desenvolvendo-se outros e novos processos de feedback, processos de interação cuja grande vantagem é a de criar laços. Gans defende que os jornalistas analisam o atual sistema político-económico numa “perspectiva natural de estado de coisas”, sendo que a procura de fontes com valor noticioso incide na estrutura do poder e na defesa noticiosa do status quo.

description: Specific heat versus temperature curves for various pressures, or magnetic fields (or some other external control parameter) have been seen to cross at a point or in a very small range of temperatures in many correlated fermion systems. We show that this behavior is related to the vicinity of a quantum critical point in these systems which leads to a crossover at some temperature T^* from quantum to classical fluctuation regime. The temperature at which the curves cross turns out to be near T^*. We have discussed the case of the normal phase of liquid Helium three and the heavy fermion systems CeAl3 and UBe13 in detail within the spin fluctuation theory. When the crossover scale is any homogeneous function of these control parameters there is always crossing at a point.

A generalized linear Hubble law for an inhomogeneous barotropic Universe

Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this work, I present a generalized linear Hubble law for a barotropic spherically symmetric inhomogeneous spacetime, which is in principle compatible with the acceleration of the cosmic expansion obtained as a result of high redshift Supernovae data. The new Hubble function, defined by this law, has two additional terms besides an expansion one, similar to the usual volume expansion one of the FLRW models, but now due to an angular expansion. The first additional term is dipolar and is a consequence of the existence of a kinematic acceleration of the observer, generated by a negative gradient of pressure or of mass-energy density. The second one is quadrupolar and due to the shear. Both additional terms are anisotropic for off-centre observers, because of to their dependence on a telescopic angle of observation. This generalized linear Hubble law could explain, in a cosmological setting, the observed large scale flow of matter, without to have recourse to peculiar velocity-type newtonian models. It is pointed out also, that the matter dipole direction should coincide with the CBR dipole one.

description: Light scattering and spin-orbit angular momentum coupling phenomena from subwavelength objects, with electric and magnetic dipolar responses, are receiving an increasing interest. Under illumination by circularly polarized light, spin-orbit coupling effects have been shown to lead to significant shifts between the measured and actual position of particles. Here we show that the remarkable angular dependence of these "optical mirages" and those of the intensity, degree of circular polarization (DoCP), and spin and orbital angular momentum of scattered photons, are all linked and fully determined by the dimensionless "asymmetry parameter" g, being independent of the specific optical properties of the scatterer. Interestingly, for g different from 0, the maxima of the optical mirage and angular momentum exchange take place at different scattering angles. In addition we show that the g parameter is exactly half of the DoCP at a right-angle scattering. This finding opens the possibility to infer the whole angular properties of the scattered fields by a single far-field polarization measurement.

Αρχικά, περιγράφεται η τεχνική των απεικονίσεων SAR και στη συνέχεια αναλύεται o τρόπος λειτουργίας και η διαδικασία παραγωγής των προϊόντων του δορυφόρου TerraSAR–X. Αναλύεται το γενικό γεωμετρικό μοντέλο του δέκτη (Range – Doppler) και οι προσεγγιστικές μέθοδοι που χρησιμοποιούνται για τη γεωαναφορά (DLT, RPF 2ου βαθμού). Στη συνέχεια γίνεται εφαρμογή των μεθόδων γεωαναφοράς σε μια διαθέσιμη απεικόνιση TerraSAR–X, που απεικονίζει περιοχή της ΒΑ Αττικής και γίνεται σύγκριση και αξιολόγηση των αποτελεσμάτων που προκύπτουν από κάθε μέθοδο γεωαναφοράς. Το επόμενο στάδιο της εφαρμογής είναι η χρήση της γεωαναφοράς με το γενικό φυσικό μοντέλο του δέκτη, για την παραγωγή ορθοφωτογραφίας της περιοχής και αξιολόγησή της ως προς την ποιότητα και τα προβλήματα που προκύπτουν. Τέλος, αναφέρονται τα συμπεράσματα από την εφαρμογή των παραπάνω διαδικασιών και οι προτάσεις για περαιτέρω επεξεργασία και αξιοποίηση τέτοιου είδους απεικονίσεων.
description: In this diploma thesis the goal is the photogrammetric processing and evaluation of TerraSAR–X images registration and orthorectification, using three different registration methods (Range – Doppler Algorithm, DLT and 2nd order RPF). The first two chapters describe the SAR technique and TerraSAR–X operation. In particular, the characteristics, geometry, imaging modes and products of TerraSAR–X are specified, as well as how these are produced. In the next, the three registration methods are analyzed, specifically how the generic sensor model that is used, works. All the three methods are applied to a TerraSAR–X image of East Attica and the results of the registration are compared to each other and evaluated. The generic sensor model is used for the production of an orthorectified image, the quality of which is evaluated, the problems that occur are referenced and the way that can they be overcomed is proposed. At the end, the conclusions of the above are cited and proposals of future work and future applications of such images are made.

description: A general graded reflection equation algebra is proposed and the corresponding boundary quantum inverse scattering method is formulated. The formalism is applicable to all boundary lattice systems where an invertible R-matrix exists. As an application, the integrable open-boundary conditions for the $q$-deformed supersymmetric $U$ model of strongly correlated electrons are investigated. The diagonal boundary K-matrices are found and a class of integrable boundary terms are determined. The boundary system is solved by means of the coordinate space Bethe ansatz technique and the Bethe ansatz equations are derived. As a sideline, it is shown that all R-matrices associated with a quantum affine superalgebra enjoy the crossing-unitarity property.

description: Nos países ocidentais, criou-se uma cultura baseada na cobrança dos impostos destinada à satisfação das necessidades públicas. Esta cultura está mais enraizada nos países nórdicos do que nos países do sul, apesar dos esforços significativos no desenvolvimento de uma educação fiscal orientada para o cumprimento de direitos e interesses e a possibilidade de utilização de mecanismos de proteção dos contribuintes. O legislador fiscal português institui um conjunto de princípios e meios de defesa nas diversas fases do procedimento e do processo tributário para a tutela dos seus direitos e interesses legalmente protegidos perante as ilegalidades praticadas pela administração tributária. Mas o sistema fiscal não está suficientemente preparado para fazer às questões colocadas pelos contribuintes, o que provoca situações de maior contencioso tributário, que se arrastam durante anos na administração e nos tribunais tributários. A solução poderá passar por uma nova cultura fiscal, uma simplificação do sistema fiscal, uma desburocratização da administração e uma maior celeridade dos tribunais tributários.

description: We present numerical solutions to the extended Doering-Constantin variational principle for upper bounds on the energy dissipation rate in turbulent plane Couette flow. Using the compound matrix technique in order to reformulate this principle's spectral constraint, we derive a system of equations that is amenable to numerical treatment in the entire range from low to asymptotically high Reynolds numbers. Our variational bound exhibits a minimum at intermediate Reynolds numbers, and reproduces the Busse bound in the asymptotic regime. As a consequence of a bifurcation of the minimizing wavenumbers, there exist two length scales that determine the optimal upper bound: the effective width of the variational profile's boundary segments, and the extension of their flat interior part.

We find that charge density modulations emerge progressively when r_s >1, even away from half-filling, with only short-range density correlations. Classical geometry dependent "magic numbers" can show up in the addition spectrum which are remarkably robust against quantum fluctuations and disorder averaging.

The basic idea is that flavons are stabilized by the balance between the negative soft mass and non-renormalizable terms in the potential. We explicitly discuss how our mechanism works in $A_4$ flavor model, and show that the field content is significantly simplified. It also works as a natural solution to the cosmological domain wall problem.

Contudo, considerava também que tal estado de igualdade só poderia e deveria ser alcançado após um processo progressivo de libertação feminina do obscurantismo moral, civil e religioso em que havia sido mergulhada pelos ditames das sociedades monárquicas, conservadoras, religiosas e antropocêntricas. O direito ao voto não era considerado prioritário, nem deveria, na idiossincrasia dominante do republicanismo inicial, ser concedido sem «restrições». Defendia-se a precedência de direitos civis, por um lado, ou a associação de um determinado estatuto laboral ou económico por outro, como exercer uma profissão liberal ou pagar impostos.

description: A class of solid-on-solid growth models with short range interactions and sequential updates is studied. The models exhibit both smooth and rough phases in dimension d=1. Some of the features of the roughening transition which takes place in these models are related to contact processes or directed percolation type problems. The models are analyzed using a mean field approximation, scaling arguments and numerical simulations. In the smooth phase the symmetry of the underlying dynamics is spontaneously broken. A family of order parameters which are not conserved by the dynamics is defined as well as conjugate fields which couple to these order parameters. The corresponding critical behavior is studied and novel exponents identified and measured. We also show how continuous symmetries can be broken in one dimension. A field theory appropriate for studying the roughening transition is introduced and discussed.

description: We present numerical solutions to the extended Doering-Constantin variational principle for upper bounds on the energy dissipation rate in plane Couette flow, bridging the entire range from low to asymptotically high Reynolds numbers. Our variational bound exhibits structure, namely a pronounced minimum at intermediate Reynolds numbers, and recovers the Busse bound in the asymptotic regime. The most notable feature is a bifurcation of the minimizing wavenumbers, giving rise to simple scaling of the optimized variational parameters, and of the upper bound, with the Reynolds number.

description: Interaction of an intense electromagnetic (EM) beam with hot relativistic plasma is investigated. It is shown that the thermal pressure brings about a fundamental change in the dynamics - localized, high amplitude, EM field structures, not accessible to a cold (but relativisic) plasma, can now be formed under well- defined conditions. Examples of the trapping of EM beams in self-guiding regimes to form stable 2D solitonic structures in a pure e-p plasma are worked out.

 Remarks. Despite its abundance in our samples, this species is not commonly cited in the literature. Following Petrushevskaya (1971), we consider this species to have an elongated spiny cephalis with indistinct neck area, and a broad thorax (~2x the cephalis width) with numerous ribs and extended spines. Illustrations published under the names Lithomelissa cf. galeata Ehrenberg (Benson, 1966), Lophophaena variabilis Popofsky (Van de Paverd, 1995), and Lophophaena buetschlii Haeckel (Van de Paverd, 1995) best fit the description of Lophophaena nadezdae in our opinion, so these specimens are included in our synonymy.

description: Let $(X,d)$ be a compact metric space and $f:X \to X$ be a self-map. The compact dynamical system $(X,f)$ is called sensitive or sensitivity depends on initial conditions, if there is a positive constant $δ$ such that in each non-empty open subset there are distinct points whose iterates will be $δ-$apart at same instance. This dynamical property, though being a very weak one, brings in the essence of unpredictability in the system. In this article, we survey various sensitivities and some properties implied by and implying such sensitivities.

Uma Perspetiva Ocidental de Alguns Princípios Milenares do Feng Shui

description: Presume-se que tenham mais de 3500 anos as bases em que se fundamenta uma corrente de pensamento analítico de origem chinesa designada por Feng Shui. Os seus princípios foram aprofundados ao longo do tempo, tendo adquirido uma abrangência capaz de interligar todos os aspetos da vida do homem e assentam na ideia de que cada indivíduo, local e objeto têm uma energia e uma vibração próprias, que se entrecruzam e influenciam permanentemente. Otimizar essa conjugação de forças e conduzir a uma "vivência harmoniosa com a energia da terra e as leis da natureza" é o objetivo do Feng Shui. Esta corrente de pensamento, que faz parte da cultura do povo chinês, tem influenciado pessoas de outros países asiáticos e também ocidentais, tendo as normas que preconiza sido aplicadas em diversos espaços incluindo grandes empresas, onde são consideradas um meio de melhorar o ambiente de trabalho. O interesse crescente pelo Feng Shui, talvez se deva ao facto de o homem da era tecnológica sentir necessidade de encontrar uma ligação à natureza e ao universo e descobrir que, ao seguir algumas regras que aquela corrente de pensamento propõe, se sente melhor consigo próprio e com aqueles que o rodeiam.

description: Quintessence models with a dark energy generated by pseudo Nambu-Goldstone bosons provide a natural framework in which to test the possibility that type Ia supernovae luminosity distance measurements are at least partially due to an evolution of the sources, since these models can have parameter values for which the expansion of the Universe is decelerating as well as values for which it is accelerating, while being spatially flat in all cases and allowing for a low density of clumped matter. The results of a recent investigation (astro-ph/0004138) of current observational bounds which allow for SNe Ia source evolution are discussed. It is found that models with source evolution still favour cosmologies with an appreciable amount of acceleration in the recent past, but that the region of parameter space which is most favoured shifts significantly.

description: In recent years, single element two-dimensional atom crystal materials have aroused extensive interest in many applications. Blue phosphorus, successfully synthesized on Au substrate by molecular beam epitaxy not long ago, shows unusual geometrical and electronic structures. We investigate the electronic structures and transport properties of zigzag blue phosphorene nanoribbons by using a first-principles method, which can be obviously tuned via different groups passivation on the both edges. The ZBPNRs-H and ZBPNRs-OH present a wide gap semiconductor property. While the ZBPNRs-O are metallic. Interestingly, the current-voltage curves of ZBPNRs-O show a negative differential resistive effect, which is independent on the ribbon width. The electric current through the ZBPNRs-O is mainly flowing along the both outside zigzag phosphorus chains via the way of P-P bond current. Through modifying the both edges with various functional groups, the ZBPNRs can display some important functional characteristics and become a candidate of NDR devices.

Veado e veadeiros na procissão do Círio de Nazaré: O mito medieval português de Dom Fuas Roupinho reencenado inconscientemente na Festa gay da Chiquita

description: o objetivo dessa pesquisa é conhecer a dinâmica da Festa da Chiquita, na cidade de Belém do Pará, Amazônia, Brasil, aplicando a técnica da analogia com o mito de Dom Fuas Roupinho que se encontra visualmente gravado no azulejo histórico da Capela da Memória, em Nazaré, Portugal. O resultado desse procedimento metodológico mostra que a Festa da Chiquita reencena o azulejo mitológico de Portugal, inconscientemente; além disso, ele coloca em evidência a figura do veado que é um símbolo gay; proporcionando finalmente um espaço simbólico de reflexão aos participantes que são induzidos a repensar acerca do melhor caminho que veado e veadeiros poderiam seguir em suas vidas. Contribui esse estudo mostrando pelo viés analógico que a Festa popular da Chiquita não é estranha à Tradição nem à Espiritualidade do Círio de Nazaré, pois no próprio azulejo histórico português é retratado de forma explosiva o embate entre o Bem e o Mal, o Sagrado e o Profano, a Ordem e o Caos, a Vida e a Morte, destacando-se Nossa Senhora no Céu entre raios e trovões.

description: We consider a system of interacting bosons in one dimension at a two-body resonance. This system, which is weakly interacting, is known to give rise to effective three-particle interactions, whose dynamics is similar to that of a two-dimensional Bose gas with two-body interactions, and exhibits an identical scale anomaly. We consider the experimentally relevant scenario of a harmonically trapped system. We solve the three-body problem exactly and evaluate the shifts in the frequency of the lowest compressional mode with respect to the dipole mode, and find that the effect of the anomaly is to increase the mode's frequency. We also consider the weak-coupling regime of the trapped many-boson problem and find, within the local density approximation, that the frequency of the lowest compressional mode is also shifted upwards in this limit. Moreover, the anomalous frequency shifts are enhanced by the higher particle number to values that should be observable experimentally.

Midnight Expressas a Product of Hollywood Orientalism
Creators: name: Akkan, Goksu
Publisher: name: E- Revista de Estudos Interculturais

description: O conceito de orientalismo tem sido uma questão recorrente nos estudos cinematográficos, seja a (má)representação de grupos minoritários em Hollywood, ou de pessoas brancas de personagens a cores em remakes de filmes do 'Oriente', ou através de uma omissão completa de representação destas personagens. A ideologia é um grande aspeto na formação dos pontos de vista das massas, e à medida que se tornam mais incorporados em dispositivos culturais como os filmes, quanto mais suavemente se desdobram e mais problemáticos se tornam. Em termos foucaultianos, o conhecimento sobre o Oriente é produzido através de filmes feitos pelo Ocidente, e graças ao seu capital infinito e amplas redes de distribuição, o Ocidente, particularmente a América, é muito mais bem sucedido em manter um domínio transcultural através desta estrutura de poder/conhecimento. Este artigo visa desconstruir os motivos por detrás do filme de Oliver Stone & Alan Parker de 1978, Midnight Express, em termos de colocar a Turquia e o povo turco na posição oriental e colocar os personagens ocidentais e brancos nas posições epistemológicas ocidentais. Algumas das questões abordadas neste artigo incluem "Como funciona o Orientalismo no contexto dos Estudos Fílmicos? Será que Gaze concede um olhar monolítico e unidirecional para o Oriente em vez do Ocidente? Como é que o slogan "baseado numa história verdadeira" serve como tática de marketing a fim de aumentar o "horror" de estar preso numa prisão turca, enquanto os factos reais eram diferentes dos factos representados no filme? Que efeitos têm estas deturpações?
