A general method for transforming non-physical configurations in BPS states
J. R. L. Santos, A. de Souza Dutra, O. C. Winter +1
In this work, we apply the so-called BPS method in order to obtain topological defects for a complex scalar field Lagrangian introduced by Trullinger and Subbaswamy. The BPS approa…
Effective electrostatic attraction between electrons due to quantum interference
Marina F. B. Cenni, Raul Corrêa, Pablo L. Saldanha
We show how, with the use of quantum interference, we can violate, in some sense, the rule that charges of equal sign always repel each other. By considering two electrons that pro…
The importance of scalar fields as extradimensional metric components in Kaluza-Klein models
P. H. R. S. Moraes, R. A. C. Correa
Extradimensional models are achieving their highest popularity nowadays, among other reasons, because they can plausible explain some standard cosmology issues, such as the cosmolo…
Oscillons in -theories: Possible occurrence in MHD
R. A. C. Correa, W. de Paula, T. Frederico +2
In this work, we report on the possibility of occurrence of oscillon configurations in the fourth state of matter. Oscillons are extremely long-lived, time-periodic, spatially-loca…
Quantum Interference of Force
Raul Corrêa, Marina F. B. Cenni, Pablo L. Saldanha
We show that a quantum particle subjected to a positive force in one path of a Mach-Zehnder interferometer and a null force in the other path may receive a negative average momentu…
