Approximate analytical solutions of the Schrödinger equation with Hulthén potential in the global monopole spacetime
Saulo S. Alves, Márcio M. Cunha, Hassan Hassanabadi +1
In this paper, we study the nonrelativistic quantum mechanics of an electron in a spacetime containing a topological defect. We also consider that the electron is influenced by the…
Effects of rotation and Coulomb type potential on the spin-1/2 Aharonov-Bohm problem
Márcio M. Cunha, Fabiano M. Andrade, Edilberto O. Silva
In this work, we investigate how both rotation and a Coulomb potential affect the quantum mechanical description of a spin- particle in the presence of the Aharonov-Bohm effec…
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…
Influence of rotation on the electronic states, magnetization and persistent current in 1D quantum ring
Luís Fernando C. Pereira, Márcio M. Cunha, Edilberto O. Silva
Inertial effects can affect several properties of physical systems. In particular, in the context of quantum mechanics, such effects have been studied in diverse contexts. In this…
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…
Non-ideal teleportation of tripartite entanglement: Einstein-Podolsky-Rosen versus Greenberger-Horne-Zeilinger schemes
Márcio M. Cunha, E. A. Fonseca, Fernando Parisio
Channels composed by Einstein-Podolsky-Rosen (EPR) pairs are capable of teleporting arbitrary multipartite states. The question arises whether EPR channels are also optimal against…
Remote preparation of states from imperfect bipartite sources
M. G. M. Moreno, Márcio M. Cunha, Fernando Parisio
Several proposals to produce {\it tripartite} -type entanglement are probabilistic even if no imperfections are considered in the processes. We provide a deterministic way to re…
Inertial-Hall effect: the influence of rotation on the Hall conductivity
Julio E. Brandão, F. Moraes, M. M. Cunha +2
Inertial effects play an important role in classical mechanics but have been largely overlooked in quantum mechanics. Nevertheless, the analogy between inertial forces on mass part…
Effects of rotation in the energy spectrum of
Jonas R. F. Lima, Julio Brandao, Marcio M. Cunha +1
In this paper, motivated by the experimental evidence of rapidly rotating molecules in fullerite, we study the low-energy electronic states of rotating fullerene within a…
