Abstract:
As aproximações de campo médio de Pierre Weiss e de Bethe-Peierls são implementadas para o modelo de Ising para ferromagnetismo, salientando-se o papel das flutuações espaciais dos momentos magnéticos localizados. Na aproximação de Bethe-Peierls, embora a Hamiltoniana não seja de partículas independentes, nós mostramos uma forma simples de se obter a energia média da rede utilizando a função de correlação spin-spin. Nós também comparamos a correlação de spins primeiros vizinhos calculada em ambas as aproximações com a solução exata para o sistema bidimensional de spins 1/2. Essa comparação dei

Abstract:
The Bethe–Peierls approximation to lattice gases is improved by introducing new self-consistent parameters relating to positional correlation between atoms. The improved method is applied to the triangular lattice with first nearest neighbour attractive interactions. Calculated critical temperature and critical thermodynamic properties show better agreement with the exact ones than those in the normal Bethe–Peierls approximation.

Abstract:
We study the transmission eigenvalues for the multipoint scatterers of the Bethe- Peierls-Fermi-Zeldovich-Beresin-Faddeev type in dimensions d = 2 and d = 3. We show that for these scatterers: 1) each positive energy E is a transmission eigenvalue (in the strong sense) of infinite multiplicity; 2) each complex E is an interior transmission eigenvalue of infinite multiplicity. The case of dimension d = 1 is also discussed.

Nesta tese estudamos o mapa de Bethe-Peierls (B. P.). Esse mapa racional é a transformação do grupo de renormalização do modelo de Potts na rede de Bethe. Ele é parametrizado pela temperatura, pelo campo magnético, pelo número de coordenação &#933 e pelo número de estados p do spin de Potts. Foram feitos cálculos para determinar as regiões no espaço de parâmetros onde existe caos. Para &#933 par não existe órbita periódica com período maior que dois. Para &#933 = 3 vários resultados analíticos são obtidos, pois o mapa é de grau três. Uma transformação recém descoberta nos permite restringir p

Orientador: Makoto Yoshida<br>Resumo: Apresenta-se um estudo das transições de fase de um material ferromagnético representado pelo modelo Blume-Capel. A investigação é realizada através da teoria de campo médio implementada através da aproximação de Bethe-Peierls. Como tarefa preliminar é proposta uma revisão detalhada da aproximação de Weiss para investigação dos fenômenos críticos de sistemas magnéticos. Nesta etapa, tanto o modelo de Ising quanto o modelo Blume-Capel são considerados. Em seguida, uma revisão do modelo de Ising através da aproximação de Bethe-Peierls, tida como mais precisa

Abstract:
In the fall of 1933, English physiologist A.V. Hill forcibly denounced the brutal Nazi racial policies, which the Nazi anti-Semite Johannes Stark then defended. Rutherford was drawn into the dispute in early 1934 and responded by first reviewing the long history of racial tolerance and academic freedom in England, and then by appealing for support for the Academic Assistance Council to help refugees. Among them were nuclear physicists Rudolf Peierls, Otto Robert Frisch, Maurice and Gertrude Goldhaber, Felix Bloch, Hans Bethe, and Walter Elsasser, who like many before him never forgot the first

Abstract:
Chapter 3 discusses the approximation schemes used to approach lattice statistical models that are not exactly solvable. In addition to the mean field approximation, it also considers the Bethe–Peierls approach to the Ising model. Moreover, there is a thorough discussion of the Gaussian model and its spherical version, both of which are two important systems with several points of interest. A chapter appendix provides a detailed analysis of the random walk on different lattices: apart from the importance of the subject on its own, it explains how the random walk is responsible for the critical properties of the spherical model.
