When describing quantum relativistic spin-1/2 particles moving in a plane one can in principle use Dirac matrices realized by either $2\times 2$ matrices (2-component spinors) or $4\times 4$ matrices (4-component spinors) in the quantum equation of motion. However, when spin is a relevant degree of freedom for particle dynamics, as when na external magnetic field is applied, it is impor...
The main purpose of this work plan is the detailed study of fermion and boson systems in low dimensions that present bound states and/or scattering states. The analytical solutions will be obtained by studying the Dirac (fermions) and Duffin-Kemmer-Petiau (bosons) equations. These solutions will be used for applications in the quantum Hall effect, spin quantum Hall effect and topologica...
In 3+1 dimensions, the relations between the isospectrality for spin-0 and spin-1/2 particles and pseudospin and pseudospin symmetries in the presence of scalar and vector potentials will be investigated. With applications in nuclear physics, the existence of antiparticles states in the presence of a mixed scalar-vector-tensor Woods-Saxon potential will also ivestigated. Assuming confin...
The Feynman-Gell-Mann version of the Dirac equation in 3+1 dimensions presents itself as a second-order equation and two components for the vector interaction. That alternative version of the Dirac equation is certainly a valuable tool for approaching the planar behavior of relativistic quantum systems and might resolve doubts relating spin as an independent degree of freedom in 2+1 dim...
The search for solutions to the Schrödinger's equation corresponding to the harmonic oscillator bound state solutions, to the pseudo-harmonic potential and the Kratzer potential is revised with the use of the method of Fourier sine and cosine transforms.
The searching for solutions of the one-dimensional Schrodinger equation corresponding to bound states of the harmonic oscillator, pseudoharmonic potential and to the Kratzer Potential is reviewed by using the Laplace transform method.
