On Quasinormal Modes for Scalar Perturbations of Static Spherically Symmetric Black Holes in Nash Embedding Framework
S. C. Ulhoa, R. G. G. Amorim, Abraão J. S. Capistrano
In this paper we investigate scalar perturbations of black holes embedded in a five dimensional bulk space. It is calculated the quasinormal frequencies of a such black holes using…
Approximative Wigner function for the Helium atom and dissipation
H. Dessano, R. G. G. Amorim, S. C. Ulhoa +1
The Schrödinger equation in phase space is used to calculate the Wigner function for the Helium atom in the approximation of a system of two oscillators. Dissipation effect is anal…
Hénon-Heiles Interaction for Hydrogen Atom in Phase Space
J. S. da Cruz Filho, R. G. G. Amorim, S. C. Ulhoa +3
Using elements of symmetry, as gauge invariance, several aspects of a Schrödinger equation represented in phase-space are introduced and analyzed under physical basis. The Hydrogen…
