On the Dirac oscillator in a spinning cosmic string spacetime in external magnetic fields: Investigation of energy spectrum and connection with the condensed matter physics
Márcio M. Cunha, Henrique S. Dias, Edilberto O. Silva
In this article, we study topological and noninertial effects on the motion of the two-dimensional Dirac oscillator in the presence of a uniform magnetic field and the Aharonov-Boh…
Relativistic quantum motion of an electron in spinning cosmic string spacetime in the presence of uniform magnetic field and Aharonov-Bohm potential
Márcio M. Cunha, Edilberto O. Silva
In this manuscript, we study the relativistic quantum mechanics of an electron in external fields in the spinning cosmic string spacetime. We obtain the Dirac equation, write the f…
Quantum particle motion on the surface of a helicoid in the presence of harmonic oscillator
Marcos C. R. Ribeiro, Márcio M. Cunha, Cleverson Filgueiras +1
The geometric potential in quantum mechanics has been attracted attention recently, providing a formalism to investigate the influence of curvature in the context of low-dimensiona…
Spin current generation and control in carbon nanotubes by combining rotation and magnetic field
Márcio M. Cunha, Jonas R. F. Lima, Fernando Moraes +2
We study the quantum dynamics of ballistic electrons in rotating carbon nanotubes in the presence of a uniform magnetic field. When the field is parallel to the nanotube axis, the…
Tripartite entanglement: Foundations and applications
Márcio M. Cunha, Alejandro Fonseca, Edilberto O. Silva
We review some current ideas about tripartite entanglement, the case representing the next level of complexity beyond the simplest one (though far from trivial), namely the biparti…
Finite-time collapse process and non-local correlations are incompatible with non-signaling theories
M. G. M. Moreno, Alejandro Fonseca, Márcio M. Cunha
We propose a hidden variable analysis of collapse dynamics in which the state's reduction process may take a finite time . A full characterization of the model is given for the…
