On the Hamilton-Jacobi method in classical and quantum nonconservative systems
A. de Souza Dutra, R. A. C. Correa, P. H. R. S. Moraes
In this work we show how to complete some Hamilton-Jacobi solutions of linear, nonconservative classical oscillatory systems which appeared in the literature and we extend these co…
A complete set of eigenstates for position-dependent massive particles in a Morse-like scenario
R. A. C. Correa, A. de Souza Dutra, J. A. de Oliveira +1
In this work we analyze a system consisting in two-dimensional position-dependent massive particles in the presence of a Morse-like potential in two spatial dimensions. We obtain t…
Wide Localized Solitons in Systems with Time and Space-Modulated Nonlinearities
L. E. Arroyo-Meza, A. de Souza Dutra, M. B. Hott
In this work we apply point canonical transformations to solve some classes of nonautonomous nonlinear Schrödinger equation namely, those which possess specific cubic and quintic -…
Emerging 2D isospectral configurations for position-dependent mass quantum systems
A. de Souza Dutra, J. A. de Oliveira, R. A. C. Correa +1
In this work we construct a general class of exactly solvable non-relativistic bi-dimensional quantum systems with position-dependent masses (PDM). These systems are isospectral to…
Real spectra for non-Hermitian Dirac equation in 1+1 dimensions with a most general coupling
V. G. C. S. dos Santos, A. de Souza Dutra, M. B. Hott
The most general combination of couplings of fermions with external potentials in 1+1 dimensions, must include vector, scalar and pseudoscalar potentials. We consider such a mixing…
Exact solvability of potentials with spatially dependent effective masses
A. de Souza Dutra, C. A. S. Almeida
We discuss the relationship between exact solvability of the Schroedinger equation, due to a spatially dependent mass, and the ordering ambiguity. Some examples show that, even in…
