    Aspectos importantes de complexidade através de modelos matemáticos simples

    Prof. Marcos Gomes Eleuterio da Luz

    Departamento de Física, UFPR

    Abstract:

    Complexidade é mais um conceito amplo do que realmente um conjunto de propriedades bem estabelecidas sobre um sistema natural. Entretanto, aspectos gerais e caracteristicas claras podem ser delineadas na definição do que seja um sistema complexo. Neste seminário iremos discutir a idea universal de sistemas complexos, pontuando seus atributos mais determinantes. Modelos matemáticos muito simples serão discutidos na tentativa de exemplificar as “impressões digitais” da complexidade.

    Buracos negros supermassivos e seu impacto sobre a evolução das galáxias

    Prof. Dr. Daniel Ruschel Dutra

    Departamento de Física | UFSC

    Abstract:

    Sabemos que toda a galáxia possui em seu centro um buraco negro com uma massa de milhões a bilhões de vezes a massa do Sol. O acúmulo de correlações observadas entre as propriedades de bojos galáticos e dos seus respectivos buracos negros supermassivos (SMBH) sugere uma ligação entre a evolução dos dois. Simulações hidrodinâmicas demonstram que a coevolução entre ambos é uma consequência natural do fluxo de material em direção ao centro da galáxia, provocando tanto a acresção que dá origem ao núcleo galático ativo (AGN), quanto favorecendo a formação de estrelas na região circum-nuclear pelo aumento da densidade do gás. Em contrapartida, os ventos e a radiação advindas do AGN, fenômenos que em conjunto são conhecidos como feedback, podem suprimir a formação estelar, impondo um limite para a massa de estrelas do bojo, um efeito que tem se provado necessário nas simulações cosmológicas. Neste seminário apresentarei um resumo de como chegamos ao presente entendimento acerca dos SMBHs, e discutirei alguns pontos ainda não completamente esclarecidos relacionados à conexão entre o AGN e sua galáxia hospedeira, abordando principalmente três aspectos da pesquisa atual na área: i) estudos observacionais do meio interestelar e das populações estelares; ii) simulações computacionais de sistema dinâmicos; e iii) análise de AGNs que apresentam grandes variações na sua emissão em períodos de anos ou menos.

    Analytically Solvable Problems in Quantum Mechanics and SWKB Quantization Condition

    Yuta Nasuda

    Tokyo University of Science

    Abstract:

    The Schrödinger-type equation appears not only in quantum mechanics but also in every corner of physics. It has long been studied what the basic feature of solvable potentials is, and how one solves the equation with those potentials analytically. Today we know infinitely many solvable potentials, but we still have no whole notion of the solvability of the Schrödinger equation. In this seminar, we first review several essential concepts in the solvability of the Schrödinger equation: factorization of Hamiltonian, shape invariance, and so on. Then we introduce the SWKB quantization condition, which is relevant to the solvability of the Schrödinger equation. We apply the condition to several solvable problems and show how they are closely connected.

    Optical spectroscopy: from a luminescent molecule to working OLED devices

    MSc Larissa Gomes França

    Department of Physics , Durham University – UK

    Abstract:

    Organic light-emitting diodes (OLEDs) have attracted tremendous interest from the luminescent display industry over the last years. Nowadays, this technology is already a part of peoples’ lives as being used in everyday items such as in mobile phones and televisions. Using organic semiconductors instead of the more traditional inorganic (i.e. GaN, InGaN, GaAs, etc.) introduces many technological advantages. Among them are flexibility, very low thickness of final luminescent displays as well as possibility to produce transparent displays and luminaries. In an OLED device, applied voltage bias induces injection of electrons and holes through the device cathode and anode, respectively. The charge carriers are transported through the device and migrate to the emissive layer where they recombine, generating light. Spin statistics based on the spin states of holes and electrons undergoing recombination leads to a 1:3 ratio between multiplicities of thus produced excited states: singlets and triplets. Considering that often triplet states do not contribute to the luminescent output of an OLED the efficiency of these devices becomes limited to 25% of what it could be. Mechanisms that enable turning non-emissive triplet states into luminescent singlets will be discussed in this talk. Key parameters to maximise efficiency of these mechanisms allowing 100% utilisation of all electron-hole recombination will also be covered.
