On the singular position-dependent mass
F. C. E. Lima, F. M. Belchior, C. A. S. Almeida
Revisiting the issue associated with Position-Dependent Mass (PDM), we reaffirm that the appropriate framework for addressing a generic PDM is the symmetrization proposed by BenDan…
Properties of a Majorana fermion ensemble with exciton-like mass
L. E. S. Machado, F. C. E. Lima, C. A. S. Almeida
Considering the relativistic scenario, we dedicate our study to the relativistic quantum description of one-dimensional Majorana fermions. Thus, we focus on aspects related to exci…
Electronic states in quantum wires on a Möbius strip
J. J. L. R. Pinto, J. E. G. Silva, C. A. S. Almeida
We study the properties of a two-dimensional non-relativistic electron gas (TDEG) constrained on wires along a Möbius strip. We considered wires around the strip and along the tran…
Differential configurational entropy for multi-field of the theory
F. C. E. Lima, C. A. S. Almeida
The topological structures of a theory with multi-field are studied. The theory is interesting because it is a theory that allows the shrinkage of topological structure…
Aspects of kink-like structures in 2D dilaton gravity
F. C. E. Lima, C. A. S. Almeida
The topological structures that arise from two-dimensional models are relevant physically and the first step towards understanding more complex systems. In this work, one studies t…
Statistical properties of linear Majorana fermions
F. C. E. Lima, A. R. P. Moreira, L. E. S. Machado +1
A Majorana fermion is the single fermionic particle that is its own antiparticle. Its dynamics is determined by the Majorana equation, where the spinor field is by definition equal…
Ringlike vortices in a logarithmic generalized Maxwell theory
F. C. E. Lima, C. A. S. Almeida
We investigate the presence of vortex structures in a Maxwell model with a logarithmic generalization. This generalization becomes important because it generates stationary field s…
