Gravitational lensing by generalized black-bounce space-times
C. Furtado, A. L. A. Moreira, J. R. Nascimento +2
We study gravitational lensing by generalized black-bounce space-times both in regimes of weak and strong field approximations. These metrics interpolate between regular blac…
Linear confinement of a scalar particle in a Gödel-type spacetime
R. L. L. Vitória, C. Furtado, K. Bakke
Based on the studies of confinement of quarks, we introduce a linear scalar potential into the relativistic quantum dynamics of a scalar particle. Then, we analyse the linear confi…
The aether-modified gravity and the Godel metric
C. Furtado, J. R. Nascimento, A. Yu. Petrov +1
We formulate the nonminimal aether-modified gravity whose action represents itself as a sum of the usual Einstein-Hilbert action and the CPT-even Lorentz-breaking aether-like gravi…
Geometric Phase for Fermionic Quasiparticles Scattering by Disgyration in Superfluids
L. C. Garcia de Andrade, A. M. de M. Carvalho, C. Furtado
We consider a Volovik's analog model for description of a topological defects in a superfluid and we investigate the scattering of quasiparticles in this background. The analog of…
