    Quantum Darwinism and the spreading of classical information in non-classical theories

    Dr. Roberto Dobal Baldijão

    Unicamp

    Abstract:

    Quantum Darwinism helps us to understand how our world ends up looking classical, besides being non-classical in nature. It posits that such emergence of a classical reality relies on the spreading of classical information from a quantum system to many parts of its environment. But what are the essential physical principles of quantum theory that make this mechanism possible? We address this question by formulating the simplest instance of Darwinism — CNOT-like fan-out interactions – in a class of probabilistic theories that contain classical and quantum theory as special cases. We determine necessary and sufficient conditions for any theory to admit such interactions. We find that every theory with non-classical features that admits this idealized spreading of classical information must have both entangled states and entangled measurements. Furthermore, we show that Spekkens’ toy theory admits this form of Darwinism, and so do all probabilistic theories that satisfy principles like strong symmetry, or contain a certain type of decoherence processes. Our result suggests the counter-intuitive general principle that in the presence of local non-classicality, a classical world can only emerge if this non-classicality can be “amplified” to a form of entanglement.

    Delta Baryons in Magnetized Neutron-Star Matter

    Kauan Dalfovo Marquez

    UFSC/FSC

    Abstract:

    Strong magnetic fields, such the ones expected to occur in the interior of neutron stars, can modify the microscopic composition of baryonic matter. In this work, we study magnetic field effects on neutron star matter containing the baryon octet and additional heavier spin-3/2 baryons (the deltas). We make use of different relativistic models for the equation of state of dense matter under the influence of strong magnetic fields, also considering the effects of the anomalous magnetic moment of leptons and baryons. We find that a strong magnetic field enhances the delta-baryon population in dense matter, while decreasing the relative density of hyperons. Astrophysical implications are drawn from the assumption that magnetic neutron stars are likely to contain delta-baryons in their interior.

    Galáxias muito jovens no universo local: como são e onde estão?

    Profa. Dra. Marina Trevisan

    Universidade Federal do Rio Grande do Sul

    Abstract:

    No universo local, existem galáxias anãs que formaram uma grande fração de suas massas estelares nas últimas centenas de milhões de anos. No entanto, pouco se sabe sobre a fração de populações estelares jovens em galáxias mais massivas. Em um estudo recente utilizando dados do Sloan Digital Sky Survey, nós identificamos um número significativo de galáxias muito jovens que formaram pelo menos 50% de sua massa estelar no último bilhão de anos. Com o objetivo de investigar a natureza desses objetos, nós realizamos uma análise detalhada das propriedades e ambiente dessas galáxias. Os resultados do nosso estudo serão apresentados neste seminário.

    Meios granulares: silos, fluxos e obstruções

    Prof. Dr. Ramon Enrique Ramayo Gonzalez

    Universidade Federal Rural de Pernambuco

    Abstract:

    Recentemente foi proposta a existência de uma transição de um estado obstruído para um não obstruído em um fluxo de partículas macroscópicas através de “gargalos” em sistemas tão diversos quanto suspensões coloidais, matéria granular ou seres vivos. Nesta palestra, inicialmente, falaremos das características deste fenômeno e sua semelhança com outros fenômenos. Mostraremos, a seguir, resultados experimentais recentemente obtidos por nós, que demonstram a existência desta transição num meio granular bidimensional submetido a vibrações verticais e sua caracterização como uma função do tamanho do canal e intensidade de vibração. Confirmaremos também a adequação do “parâmetro de fluxo” como o parâmetro de ordem, e justificaremos a substituição da aceleração máxima reescalonada do sistema, como parâmetro de controle, por uma velocidade adimensional que pode ser vista como a raiz quadrada da razão entre energia cinética e potencial.
