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…
Effects of curvature on the electronic states of a two-dimensional mesoscopic ring
Luís Fernando C. Pereira, Fabiano M. Andrade, Cleverson Filgueiras +1
The effects of surface curvature on the motion of electrons in a mesoscopic two-dimensional ring on a cone in the presence of external magnetic fields are examined. The approach fo…
Self-adjoint extension approach for singular Hamiltonians in (2+1) dimensions
Vinicius Salem, Ramon F. Costa, Edilberto O. Silva +1
In this work, we review two methods used to approach singular Hamiltonians in (2+1) dimensions. Both methods are based on the self-adjoint extension approach. It is very common to…
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…
Modifications of electron states, magnetization and persistent current in a quantum dot by controlled curvature
Luis Fernando C. Pereira, Fabiano M. Andrade, Cleverson Filgueiras +1
In this work, we use the thin-layer quantization procedure to study the physical implications due to curvature effects on a quantum dot in the presence of an external magnetic fiel…
