Ansatz de Bethe e princípio variacional aplicados a sistemas de poucas partículas interagentes em um potencial harmônico unidimensionalLima, Diefferson Rubeni da Rosa de January 2014 (has links)
Neste trabalho nós desenvolvemos uma abordagem baseada no método do ansatz de Bethe e no princípio variacional para encontrar a energia do estado fundamental para sistemas unidimensionais formados por um número pequeno de particulas interagentes. Particularmente, nós investigamos sistemas de duas e três partículas interagentes aprisionados em uma armadilha harmônica unidimensional. Nossos resultados apresentam uma boa concordância com as soluções analíticas e numéricas existentes na literatura. Também determinamos a densidade de probabilidade e a função de correlação de pares do sistema. Nossa abordagem é bastante genérica e permite o estudo de sistemas de poucas partículas mais complexos, alguns de interesse experimental, que não apresentam solução analítica. / In this work we develop an approach based on the Bethe ansatz method and the variational principle to nd the ground state energy for a one-dimensional few-body system. We investigate a system of two and three interacting particles con ned in a one-dimensional harmonic trap. Our results show a good agreement with existing analytical and numerical results. We also determine the probability density and the pair correlation function of the system. Our approach is very general and enables the study of more complex few-body systems, some of them of experimental interest, where no exact analytical solution is available.
