In this study, the energy equation and normalized wave function were obtained by solving the Schrödinger equation analytically utilizing the Eckart-Hellmann potential and the Nikiforov-Uvarov method. Fisher information and Shannon entropy were investigate... see more

In this study, the Schrödinger equation with the Hulthén plus screened Kratzer potentials (HSKP) are solved via the Nikiforov-Uvarov (NU) and the series expansion methods. We obtained the energy equation and the wave function in closed form with Greene-Al... see more

 
The propagation of light in a guided medium is generally described by the Maxwell’s equations. For long lengths of fiber, the Nonlinear Schrödinger (NLS) wave equation is typically derived under a few approximations on the waveguide properties of the guid... see more

We consider the focusing Nonlinear Schrödinger equation posed on the one dimensional line, with nonzero background condition at spatial infinity, given by a homogeneous plane wave. For this problem of physical interest, we study the initial value problem ... see more

The aim of this research paper is to establish sucient conditions for the nonexistence of global weak solution to the nonlinear Schrödinger equation on the Heisenberg group. The results are shown by the use of test function theory and extended t... see more

Esta resenha nasceu da constatação de que a obra Mi Concepción del Mundo, uma seleção de textos filosóficos de autoria de Erwin Schrödinger, laureado com o prêmio Nobel de Física de 1933, não possui, ainda, edição em língua portuguesa, não obstante sua ex... see more

We count invertible Schrödinger operators (perturbations by diagonal matrices of the adjacency matrix) over finite fields for trees, cycles and complete graphs. This is achieved for trees through the definition and use of local invariants (algebraic const... see more

In this paper, we have presented the exact solutions of the Schrödinger equation with the family of potentials V(r)=A/r^2-B/r+Cr^(d+1). We have obtained the energy eigenvalues and the corresponding wave functions expressed in terms of the associated Lague... see more
