This paper has studied the problem of natural frequencies for Euler-Bernoulli beams having non-uniform crosssection. The numerically-obtained solutions were compared to asymptotic solutions obtained by the WentzelKramers-Brillouin ...

A quantização geométrica é um procedimento para construir uma teoria quântica a partir de elementos geométricos de um sistema clássico considerado como uma variedade simplética. Ele fornece uma abordagem matemática para ...

Neste trabalho foram resolvidos, através da Equação de Schrödinger Independente do tempo, o potencial biestável para um sistema de dois níveis do Poço Duplo Quadrado Unidimensional Simétrico, de forma exata e por métodos ...

The soft stadium is defined by a monomial potential with exponent α as a parameter, such that α → ∞ corresponds to the billiard. The practical use of the quantum section method depends only on the partial separability of ...

In this reply to the comment on 'Quantization rules for bound states in quantum wells' we point out some interesting differences between the supersymmetric Wentzel-Kramers-Brillouin (WKB) quantization rule and a matrix ...
