Exploring light propagation in nonlinear electrodynamics: phase and group velocities and related phenomena
T. W. Cruz, V. A. De Lorenci, E. Guzmán-Herrera +1
Nonlinear electrodynamics has been an important area of research for a long time. Investigations based on nonlinear Lagrangians, such as Euler-Heisenberg and Born-Infeld, are instr…
Anisotropic motion of an electric dipole in a photon gas near a flat conducting boundary
G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1
The quantum Brownian motion of a single neutral particle with nonzero electric dipole moment placed in a photon gas at fixed temperature and close to a conducting wall is here exam…
Probing thermal fluctuations through scalar test particles
G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1
The fundamental vacuum state of quantum fields, related to Minkowski space, produces divergent fluctuations that must be suppressed in order to bring reality to the description of…
New point-like sources and a conducting surface in Maxwell-Chern-Simons electrodynamics
L. H. C. Borges, F. E. Barone, C. C. H. Ribeiro +3
We investigate some aspects of the Maxwell-Chern-Simons electrodynamics focusing on physical effects produced by the presence of stationary sources and a perfectly conducting plate…
Analogues of gravity-induced instabilities in anisotropic metamaterials
C. C. H. Ribeiro, D. A. T. Vanzella
In the context of field theory in curved spacetimes, it is known that suitable background spacetime geometries can trigger instabilities of fields, leading to exponential growth of…
Vacuum induced dispersions on the motion of test particles in dimensions
G. H. S. Camargo, V. A. De Lorenci, C. C. H. Ribeiro +1
When the vacuum state of a scalar or electromagnetic field is modified by the presence of a reflecting boundary, an interacting test particle undergoes velocity fluctuations. Such…
Remarks on the influence of quantum vacuum fluctuations over a charged test particle near a conducting wall
V. A. De Lorenci, C. C. H. Ribeiro
Quantum vacuum fluctuations of the electromagnetic field in empty space seem not to produce observable effects over the motion of a charged test particle. However, when a change in…
Vacuum fluctuations of a scalar field near a reflecting boundary and their effects on the motion of a test particle
G. H. Camargo, V. A. De Lorenci, C. C. H. Ribeiro +2
The contribution from quantum vacuum fluctuations of a real massless scalar field to the motion of a test particle that interacts with the field in the presence of a perfectly refl…
Probing quantum vacuum fluctuations over a charged particle near a reflecting wall
V. A. De Lorenci, C. C. H. Ribeiro, M. M. Silva
We investigate the influence of the vacuum fluctuations of a background electric field over a charged test particle in the presence of a perfectly reflecting flat wall. A switching…
A Model for Lightcone Fluctuations due to Stress Tensor Fluctuations
C. H. G. Bessa, V. A. De Lorenci, L. H. Ford +1
We study a model for quantum lightcone fluctuations in which vacuum fluctuations of the electric field and of the squared electric field in a nonlinear dielectric material produce…
