strong quantum Darwinism and strong independence are equivalent to spectrum broadcast structure
Physical Review Letters, 2019Co-Authors: Thao P Le, Alexandra OlayacastroAbstract:How the objective everyday world emerges from the underlying quantum behavior of its microscopic constituents is an open question at the heart of the foundations of quantum mechanics. Quantum Darwinism and spectrum broadcast structure are two different frameworks providing key insight into this question. Recent works, however, indicate these two frameworks can lead to conflicting predictions on the objectivity of the state of a system interacting with an environment. Here, we provide a resolution to this issue by defining strong quantum Darwinism and proving that it is equivalent to spectrum broadcast structure when combined with strong independence of the subenvironments. We further show that strong quantum Darwinism is sufficient and necessary to signal state objectivity without the requirement of strong independence. Our Letter unveils the deep connection between strong quantum Darwinism and spectrum broadcast structure, thereby making fundamental progress toward understanding and solving the emergence of classicality from the quantum world. Together they provide us a sharper understanding of the transition in terms of state structure, geometry, and quantum and classical information.

Social Darwinism in American Human Geography: a study of selected works by Ellsworth Huntington and Ellen Semple
Faculdade de Filosofia Letras e Ciências Humanas, 2020Co-Authors: Coscioni, Fernando JoséAbstract:A tese busca, à luz de uma preocupação metodológica que coloca em diálogo a História Intelectual e a História da Geografia, compreender o impacto do Darwinismo Social sobre o pensamento do final do século XIX e início do século XX, com o objetivo de elucidar as relações existentes entre essa corrente intelectual e a fundamentação epistemológica e filosófica das obras de Ellsworth Huntington (1876-1947) e Ellen Semple (1863-1932), dois dos principais autores da Geografia Humana no contexto nacional estadunidense das décadas de 1900 a 1930. São estudadas as relações existentes entre a institucionalização da Geografia acadêmica nos EUA, a força do Darwinismo Social como um quadro de referência filosófico e epistemológico no campo intelectual do período, as trajetórias dos dois geógrafos e as ideias contidas nas obras \"Civilization and Climate\" (1915/1924), de Ellsworth Huntington, e \"Influences of Geographic Environment\" (1911), de Ellen Semple. Além dessas duas obras que recebem análises mais detalhadas, são abordadas outras contribuições de ambos à disciplina, buscando situar seus respectivos esforços intelectuais no quadro socioeconômico, geopolítico, epistemológico e ideológico mais amplo que caracterizou as primeiras décadas do século XX.The thesis seeks, under a methodological concern that puts in dialogue Intellectual History and History of Geography, to understand the impact of Social Darwinism on late nineteenth and early twentieth century thinking in order to elucidate existing relationships between this intellectual current and the epistemological and philosophical foundation of the works of Ellsworth Huntington (1876-1947) and Ellen Semple (1863-1932), two of the leading authors of Human Geography in the USA national context from the 1900s to 1930s. The relationships among the institutionalization of academic geography in the USA, the strength of Social Darwinism as a philosophical and epistemological reference framework in the intellectual field of the period, the trajectories of the two geographers and the ideas contained in the works \"Civilization and Climate\" (1915/1924), by Ellsworth Huntington, and \"Influences of Geographic Environment\" (1911), by Ellen Semple, are studied along the thesis. In addition to these two works which receive more detailed analysis, other contributions of both of them for the discipline are addressed in order to situate their respective intellectual efforts in the broader socioeconomic, geopolitical, epistemological and ideological scenario that characterized the first decades of the twentieth century

Social Darwinism in early twentieth century Human Geography: the case of Ellen Semple’s work Influences of Geographic Environment
Programa de Pós-Graduação de Geografia Humana e Programa de Pós-Graduação de Geografia Física, 2018Co-Authors: Coscioni, Fernando JoséAbstract:The article seeks to explain the relationship between Social Darwinism, the institutionalization of Human Geography in the United States in the first decades of the twentieth century, and the epistemological and philosophical positions underlying the work Influences of Geographic Environment(1911) written by Ellen Semple (1863-1932). The book in question was one of the main comprehensive attempts at theoretical systematization of Human Geography produced in the US during the critical period of expansion of the discipline university's presence in the country. We’ll defend the hypothesis that the ideas presented by the geographer in this work clearly demonstrate that the construction of the disciplinary field in the English-speaking world took place from the internalization of intellectual positions derived from the evolutionary debate that arrived at the Human Sciences through Social Darwinism and that were favored by the geopolitical context of the rise of imperialism.O artigo busca explicar a relação entre o Darwinismo Social, a institucionalização da Geografia Humana nos EUA nas primeiras décadas do século XX e as posturas epistemológicas e filosóficas que fundamentam a obra “Influences of Geographic Environment” (1911), escrita por Ellen Semple (1863-1932). O livro em questão foi uma das principais tentativas mais extensas de sistematização teórica da Geografia Humana produzidas nos EUA durante o período crítico de expansão da presença universitária da disciplina no país. Defenderemos a hipótese de que as ideias expostas pela geógrafa nesse trabalho evidenciam claramente que a construção do campo disciplinar no mundo de língua inglesa se deu a partir da internalização de posturas intelectuais derivadas do debate evolucionista que chegaram às Ciências Humanas através do Darwinismo Social e que foram favorecidas pelo contexto geopolítico de ascensão do imperialismo.

Anti-Zeno-based dynamical control of the unfolding of quantum Darwinism
'American Physical Society (APS)', 2020Co-Authors: Lorenzo Salvatore, Paternostro Mauro, Palma G. MassimoAbstract:We combine the collisional picture for open system dynamics and the control of the rate of decoherence provided by the quantum (anti-)Zeno effect to illustrate the temporal unfolding of the redundant encoding of information into a multipartite environment that is at the basis of quantum Darwinism, and to control it. The rate at which such encoding occurs can be enhanced or suppressed by tuning the dynamical conditions of system-environment interaction in a suitable and remarkably simple manner. This would help the design of a new generation of quantum experiments addressing the elusive phenomenology of quantum Darwinism and thus its characterization

Phylogenie und archaische Erbe in Freuds Werk: die Suche nach der Ätiologie und die Leidenschaft des real
'FapUNIFESP (SciELO)', 2017Co-Authors: Vetö Honorato Silvana, Vallejo, Mauro SebastiánAbstract:La obra teórica de Sigmund Freud contiene múltiples referencias al tópico de la herencia arcaica y la filogenia. El objetivo de este artículo es analizar ese aspecto de su obra, con el cometido de señalar las limitaciones de las interpretaciones más frecuentes, que tienden a ver allí un impacto del Darwinismo en Freud o de simplemente negar su relevancia. Intentaremos mostrar que el recurso a la filogenia respondió enteramente a un interrogante clínico por la etiología de las neurosis.O trabalho teórico de Sigmund Freud contém várias referências ao tema da herança arcaica, ou filogenia. O objetivo deste artigo é analisar esse aspecto de sua obra, com a tarefa de apontar as limitações das interpretações mais comuns, que tendem a ver um impacto do Darwinismo em Freud ou simplesmente negar sua relevância. Procuramos demonstrar que o uso da filogenia respondeu inteiramente a uma pergunta clínica sobre a etiologia da neurose.The theoretical work of Sigmund Freud contains multiple references to the topic of archaic inheritance and phylogeny. The aim of this paper is to analyze this aspect of his work, in order to point out the limitations of its most frequent interpretations, which tend to perceive the impact of Darwinism on Freud, or simply deny its relevance. We intend to prove that using phylogeny responded entirely to a clinical question regarding the etiology of neuroses.Le travail théorique de Sigmund Freud contient plusieurs références au sujet de l’héritage archaïque ou de la phylogénie. Le but de cet article est d’analyser cet aspect de son travail, soit de souligner les limites des interprétations les plus courantes qui ont tendance à voir un impact du Darwinisme chez Freud ou tout simplement à nier sa pertinence. Nous essayons ainsi de démontrer que l’utilisation de la phylogénie répondait parfaitement à la question clinique sur l’étiologie de la névrose.Die theoretische Arbeit Sigmund Freuds enthält mehrere Verweise auf das Thema der archaischen Erbschaft, welche auch Phylogenie genannt wird. Das Ziel dieser Arbeit ist es, diesen Aspekt seiner Arbeit zu analysieren und die Grenzen der häufigsten Interpretationen aufzuzeigen, welche dazu neigen, den Einfluss des Darwinismus auf Freud zu sehen, oder einfach seine Relevanz zu leugnen. Wir versuchen aufzuzeigen, dass die Einbeziehung der Phylogenie die klinische Frage der Ätiologie der Neurose gänzlich löste.Fil: Vetö Honorato, Silvana.
