Previous issue date: 2016-07-29 / Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) / Nesta dissertação vamos estudar um problema de três corpos via aproximação de Born-Oppenheimer em duas dimensões para um sistema constituído de duas partículas pesadas e uma leve. Considerando uma interação de contato entre a partícula leve e as pesadas e desconsiderando a interação entre as pesadas, estudamos o efeito do momento angular e da diferença de massa entre as partículas. Notamos que diminuindo a diferença de massa entre as partículas encontramos um número menor de estados ligados. Conforme aumentamos o momento angular observamos um número menor de estados ligados, isto porque o momento angular soma ao sistema um potencial repulsivo, tornando o sistema mais fracamente ligado. Considerando um potencial gaussiano entre as partículas pesadas calculamos a energia de três corpos e o raio quadrático médio. Observamos que a introdução deste potencial torna possível o rompimento do sistema de três corpos e o fenômeno de tunelamento. Estudando o raio quadrático médio percebemos que na região de tunelamento o tamanho do sistema varia consideravelmente, tornando esta região interessante de ser detectada experimentalmente. / In this thesis we study mass-imbalanced three-body system in two dimensions using BornOppenheimer approximation. Considering the heavy-light particle system interacting through zero-range interaction and disregarding interaction between the heavy-heavy, we study effects the angular momentum and mass ratio difference. Decreasing the mass difference between the heavy and the light particles a smaller number of bound states is found. Increasing the angular momentum we add to the system a repulsive potential, making the system weakly bounded, in this case a small number of bound states are expected. Considering a gaussian potential between the heavy-heavy particles it is possible to unbounded the system and observe tunneling phenomena. The considerable change in the tunneling region for the mean square radii indicates an increase in the system size, making this region interesting to be experimentally detected. / CNPq: 147716/2014.4

Accurate Born-Oppenheimer Molecular Calculation with Explicitly Correlated Gaussian FunctionTung, Wei-Cheng January 2012 (has links)
The research over-viewed in this dissertation concerns very accurate variational calculations of the molecular systems with more than two electrons under the assumption of the Born-Oppenheimer (BO) approximation. The centerpiece of this research is the use of explicitly correlated Gaussian (ECG) basis functions with floating centers to generate the potential energy curve (PEC) and potential energy surface (PES) of the considered molecular systems. One challenge of such calculations is the occurrence of the linear dependency between basis functions in the process of basis set optimization. The BO PECs generated with ECG basis sets were limited to two-electron molecular systems for a few decades prior to the implementation of the author's approaches to this issue. These approaches include methods for a partial remedy to linear dependence, better guessing of initial basis functions, permanently removing the restriction of memory usage in parallel computer systems, and efficiently paralleling the calculations. The approach effectively utilizing the super computer systems yields benefits not only to the ECG calculations but could also be useful in the fields that require the significant amount of the computational resources. These procedures were implemented in computer codes that were run quite extensively on several parallel computer systems during the period of the author's Ph.D study. The calculated adiabatic PECs and the rovibrational energy levels are proven to be the most accurate ones to date. The dissertation is primarily based on the content of the papers that were published in co-authorship with my scientific advisor and other collaborators in several scientific journals. It also includes some details that were not considered in the publications but are essential for the completeness and good understanding of the presented work. In order to provide readers an insight into the development of the ECG based BO molecular calculation, the published results of many calculations are classified and presented in a comprehensive way.

Hur vi lärde oss att älska bomben – en studie i svensk atombombspress 1945-52Steen, Christian, Mattsson, Sebastian January 2012 (has links)
Inspired by the great arts of scientist and poet Robert J. Oppenheimer, the purpose of this paper is to unveil and highlight the attitudes towards the atomic bomb in Swedish newspapers during the early and most vivid years of the atomic era. By pinpointing and analysing central discourses caused by this paradigm breaking invention, this academic effort reveals the morbid moral of the story caused by loose speculations and the lack of knowledge.
