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…
Missing Aharonov-Casher geometric quantum phase
K. Bakke, C. Furtado
From the interaction of the permanent magnetic dipole moment of a neutral particle with an electric field inside a long non-conducting cylindrical shell of inner radius and…
A Quantum Ring in a Nanosphere
A. L. Silva Netto, B. Farias, J. Carvalho +1
In this paper we study the quantum dynamics of an electron/hole in a two-dimensional quantum ring within a spherical space. For this geometry, we consider a harmonic confining pote…
Landau Quantization for -Type Neutral Atoms in an Homogeneous Spin-Dependent Gauge Potential
Bruno Farias, Claudio Furtado
We investigate the quantum dynamics of neutral atoms subject to a uniform spin-dependent gauge field. In particular, we analyze a simple experimental scheme to generate the Landau…
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…
Evidence for field induced proximity type behavior in ferromagnetic nanofluid
S. Sergeenkov, C. Stan, C. P. Cristescu +3
We report some unusual magnetic properties observed in CoFe2O4 based ferrofluid (with an average particle size of D = 6 nm). More precisely, in addition to the low-field ferromagne…
