The Einstein-Podolsky-Rosen Argument and the Bell Inequalities
No full textIn 1935 Einstein, Podolsky, and Rosen (EPR) published an important paper in which they claimed that the whole formalism of quantum mechanics together with what they called ``Reality Criterion'' imply that quantum mechanics cannot be complete. That is, there must exist some elements of reality that are not described by quantum mechanics. There must be, they concluded, a more complete description of physical reality behind quantum mechanics. There must be a state, a hidden variable, characterizing the state of affairs in the world in more details than the quantum mechanical state, something that also reflects the missing elements of reality. Under some further but quite plausible assumptions, this conclusion implies that in some spin-correlation experiments the measured quantum mechanical probabilities should satisfy particular inequalities (Bell-type inequalities). The paradox consists in the fact that quantum probabilities do not satisfy these inequalities. And this paradoxical fact has been confirmed by several laboratory experiments in the last three decades. The problem is still open and hotly debated among both physicists and philosophers. It has motivated a wide range of research from the most fundamental quantum mechanical experiments through foundations of probability theory to the theory of stochastic causality as well as the metaphysics of free will
And now I can say it too: Jewish identity in the poetry of Michael Rosen
No full textEsta dissertação investiga o processo de construção da identidade judaica na obra do poeta britânico Michael Rosen através da análise de oito poemas narrativos de caráter autobiográfico. Rosen é um dos autores de maior destaque em seu país na atualidade, sendo reconhecido por seu ativismo político e por seus livros destinados ao público infantil. A partir dos textos selecionados, este estudo explora a noção de infância e suas relações com a memória, levando em conta como elas influenciam o processo de elaboração de uma identidade judaica diaspórica desde a segunda metade do século XX, da maneira que encontramos na poesia de Rosen. Esta pesquisa acerca da identidade judaica do autor concentra-se em três aspectos principais: a língua ídiche, a herança cultural asquenaze nas configurações pós-guerra e a influência da memória coletiva no âmbito individual, conforme elaboradas nas narrativas RosenThis dissertation investigates the process of the construction of a Jewish identity in the poetry of British author Michael Rosen through the analysis of eight autobiographical narrative poems. Rosen is one of the most prominent authors in his country today, recognized for his political activism and his books for children. Using specific texts, this study explores the notion of childhood and its associations with memory, taking into account how they influence the development of a diasporic Jewish identity since the second half of the 20th century, as found in Rosen\'s poetry. This research on the author\'s Jewish identity focuses on three main aspects: the Yiddish language, the Ashkenazi cultural heritage in post-war conditions, and the influence of collective memory on the individual level, as elaborated in Rosen\'s narrative

Martial between Rome and Bilbilis
No full textThis article traces and synthesizes the complex representation of the motif city-countryside in Martial’s epigrams, taking into account its different, sometimes contradictory, aspects. These aspects, so far looked at either out of context or only within the framework of single books, are brought together and, above all, are seen in their different functions (especially the self-fashioning of the author) and diachronic development. Section 2 starts from Epigram1.49 to demonstrate the fluctuating evaluation of the appropriateness or otherwise of a life in the city or countryside, depending on one’s age, the alternation of one’s activities or perspective (patron or poet). Section 3 explores the tension between fond ideas of leaving the city behind and the ‘reality’ of being in provincial surroundings, unconducive to poetry, where positive evaluations of the countryside are lacking. In section 4, I explore Books 4–9 where otiumis sometimes situated in an urban context, while the opposition to life in the countryside recedes into the background. In so far as the relationship between city and coun-tryside plays a role, they are harmonious. By contrast, Book 10 returns to the motifs encountered in Books 1–2, but here they become more complex and problematic as they are linked to Martial’s move from Rome to Celtiberia (section 5). In Book 12, as earlier in Book 3, the dominant opposition is that between Rome and not-Rome (section 6). I conclude that the picture of a Martial constantly and consistently dreaming of a countryside existence must be adjusted: the depiction of city and countryside is not constant over the course of Books 1–12 but changes in accordance with the construction of the poet’s identity and his history within the text
The "Ethereal State:" Weddings in Modern American Feminist Drama
No full textThis study investigates weddings as moments of transition for women in three plays by American women playwrights in the late twentieth century. The study builds on the works of Gayle Austen and Judith E. Barlow on plays by American women through the application of the ideas of Stephanie Coontz, Jaclyn Geller, Chrys Ingraham, Jackie Stacey and Lynn Pearce. Jane Bowles's In the Summer House (1953) investigates the influence of the mother-daughter relationship on female identity formation and the resulting anxieties regarding marriage and maturation produced by the complexities of the mother-daughter bond. While exploring the bride's psychology, the play also probes the relationship between socio-economic conditions and marriage, showcasing how economic realities inform women's experiences of weddings. Henley's Impossible Marriage (1998) considers the tensions between societal conventions and personal desires, asserting the existence of true love while demonstrating the challenges society places on the individual's passions. Finally Ruhl's Eurydice (2006) showcases how multiple types of love affect women by moving Eurydice from the myth's margins into the play's center. In imagining loves intertwinement with loss, the play disproves the belief that romantic love ensures eternal happiness and makes up for past tragedies.Advisor(s): Carol Rosen.

Adiabatic Rosen-Zener interferometry with ultracold atoms
No full textWe propose a time-domain "interferometer" based on double-well ultracold atoms through a so-called adiabatic Rosen-Zener process, that is, the barrier between two wells is ramped down slowly, held for a while, and then ramped back. After the adiabatic Rosen-Zener process, we count the particle population in each well. We find that the final occupation probability shows nice interference fringes. The fringe pattern is sensitive to the initial state as well as the intrinsic parameters of the system such as interatomic interaction or energy bias between two wells. The underlying mechanism is revealed and possible applications are discussed.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000268616900152&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701OpticsPhysics, Atomic, Molecular & ChemicalSCI(E)EI10ARTICLE1null8
Mill como filósofo moral (Algúns comentarios sobre o Mill de Fredrick Rosen)
No full textFirst, I want to thank Professor Rosen’s deep and illuminating study of the Philosophy of Stuart Mill. In my view, one of the most important contributions of the author is his claim that Mill was not only a social moralist but was primarily a philosopher and a logician. In many ways, Rosen is right. Mill was not a moral philosopher, or at least was not only a moral philosopher. However, he was concerned with the part of philosophy that deals with morality and enthusiastically defended both the welfare and the individual and social development. First, I want to thank Professor Rosen’s deep and illuminating study of the Philosophy of Stuart Mill. In my view, one of the most important contributions of the author is his claim that Mill was not only a social moralist but was primarily a philosopher and a logician. In many ways, Rosen is right. Mill was not a moral philosopher, or at least was not only a moral philosopher. However, he was concerned with the part of philosophy that deals with morality and enthusiastically defended both the welfare and the individual and social development. As we say, Mill was not only a moral philosopher, because in many cases he anticipated to contemporary metaphysics, showing that the principles of normative ethical could be defended so that the human intellect helps to understand them. Even so, it should be added that Mill was, however, a reformer and a defender of moral character education. I think no exaggeration to say that Mill used logic and reasoning as ways to promote intellectual and moral development of all human beings, which is necessary for the individual improvement of welfare and social harmony. Reading Mill carefully is discovered that all his reasoning and use of the senses is aimed at deepening the welfare of all members of humanity, recommending the highest pleasures (more developed). Being a moral philosopher is not so, and as Fred Rosen suggests in his brilliant work, an obstacle to Mill being a defender of ethical revolution of society, i.e., the transformation of human life. Thus, while I deeply admire the contribution of Professor Rosen to the study of Mill, I will show my disagreement with it at some length, and finally I will also summarize the main points of convergence between the study of Rosen and my own view of John Stuart Mill’s thought.DOI http://dx.doi.org/10.15304/t.20.1.2623En primer lugar, quiero agradecer al Profesor Rosen su profundo y esclarecedor estudio sobre la Filosofía de Stuart Mill. A mi modo de ver, una de las contribuciones más importantes del autor es su afirmación de que Mill no era solamente un moralista social sino que era ante todo un filósofo y un lógico. En muchos sentidos, Rosen esta en lo cierto. Mill no era un filósofo moral, o al menos no era sólo un filósofo moral. Sin embargo, le preocupaba la parte de la filosofía que se ocupa de la moralidad y defendía de forma entusiasta el bienestar tanto como el desarrollo individual y social. Como decimos, Mill no era únicamente un filósofo moral, porque en muchos casos se anticipó a la metafísica contemporánea, mostrando que los principios de ética normativa podían ser defendidos de manera que el intelecto humano ayudase a comprenderlos. Sin embargo, debería añadirse que Mill fue, no obstante, un moralista reformador y un defensor de la educación moral. Creo que no exagerado afirmar que Mill usó la lógica y el razonamiento como formas de promover el desarrollo intelectual y moral de todos los seres humanos, lo cual es necesario para el perfeccionamiento individual del bienestar y la armonía social. Leyendo a Mill cuidadosamente se descubre que todo su razonamiento y uso de los sentidos está dirigido a profundizar sobre el bienestar de todos los miembros de la humanidad, recomendando los placeres más altos (más desarrollados). Ser un filósofo moral no es, así, y como parece sugerir Fred Rosen en su brillante trabajo, un obstáculo para que Mill sea un defensor de la revolución moral de la sociedad, es decir, de la transformación de la vida humana. Así pues, aunque admiro profundamente la contribución del Profesor Rosen al estudio de Mill, mostraré mis desacuerdos con ella con una cierta extensión, y resumiré finalmente los principales puntos de convergencia entre el estudio de Rosen y mi propio punto de vista sobre el pensamiento de John Stuart Mill.DOI http://dx.doi.org/10.15304/t.20.1.2623En primeiro lugar, quero agradecer ao Profesor Rosen o seu profundo e esclarecedor estudo sobre a Filosofía de Stuart Mill.

Genuine Multipartite Einstein-Podolsky-Rosen Steering
No full textWe develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This nonlocality is the natural multipartite extension of the original EPR paradox. Useful properties emerge that are not guaranteed for genuine multipartite entangled states. In particular, there is a close link with the task of one-sided, device-independent quantum secret sharing. We derive inequalities to demonstrate multipartite EPR steering for Greenberger-Horne-Zeilinger and Gaussian continuous variable states in loophole-free scenarios.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000328884000003&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)EIPubMed32ARTICLE2525040311
Efficient Scheme for Perfect Collective Einstein-Podolsky-Rosen Steering
No full textA practical scheme for the demonstration of perfect one-sided device-independent quantum secret sharing is proposed. The scheme involves a three-mode optomechanical system in which a pair of independent cavity modes is driven by short laser pulses and interact with a movable mirror. We demonstrate that by tuning the laser frequency to the blue (anti-Stokes) sideband of the average frequency of the cavity modes, the modes become mutually coherent and then may collectively steer the mirror mode to a perfect Einstein-Podolsky-Rosen state. The scheme is shown to be experimentally feasible, it is robust against the frequency difference between the modes, mechanical thermal noise and damping, and coupling strengths of the cavity modes to the mirror.National Natural Science Foundation of China [11274025, 61475006, 11121091]SCI(E)[email protected]
Rosen-Zener transition in a nonlinear two-level system
No full textWe study the Rosen-Zener transition (RZT) in a nonlinear two-level system in which the level energies depend on the occupation of the levels, representing a mean-field type of interaction between the particles. We find that the nonlinearity could affect the quantum transition dramatically. At certain nonlinearity the 100% population transfer between two levels is observed and found to be robust over a very wide range of external parameters. On the other hand, the quantum transition could be completely blocked by a strong nonlinearity. In the sudden and adiabatic limits we have derived analytical expressions for the transition probability. Numerical explorations are made for a wide range of parameters of the general case. Possible applications of our theory to Bose-Einstein condensates (BECs) and solid-state physics are discussed.OpticsPhysics, Atomic, Molecular & ChemicalSCI(E)EI0ARTICLE1null7
