Numerical study of non-relativistic quantum systems and small oscillations induced in a helically twisted geometry
C. F. S. Pereira, R. L. L. Vitória, A. R. Soares +3
We investigate bound states of a non-relativistic scalar particle in a three-dimensional helically twisted (torsional) geometry, considering both the free case and the presence of…
Geometrical optical activity induced by a continuous distribution of screw dislocations
Humberto Belich, Edilberto O. Silva
We study light propagation in a medium with uniform torsion, modeled as a continuum of screw dislocations within the geometric theory of defects. By solving Maxwell's equations in…
Light deflection and gravitational lensing effects in acoustic black-bounce spacetime
C. F. S. Pereira, A. R. Soares, M. V. de S. Silva +2
In the present work, we analyze the gravitational deflection for a light beam in the weak and strong field regimes for the gravitational analogue geometry of an acoustic black hole…
Symplectic Representation of the Ginzburg-Landau Theory
E. A. Reis, G. X. A. Petronilo, R. G. G. Amorim +3
In this work, the Ginzburg-Landau theory is represented on a symplectic manifold with a phase space content. The order parameter is defined by a quasi-probability amplitude, which…
