Polarization and energy ellipsoids for an introductory visualization of tensors
Danilo T. Alves, Lucas Queiroz, Jeferson Danilo L. Silva
In ``The Feynman Lectures on Physics'' is discussed an introduction to tensors by means of the polarization tensor, including a way of ``visualizing'' this tensor via the energy el…
Renormalization of the band gap in 2D materials near an interface between two dielectrics
Alessandra N. Braga, Wagner P. Pires, Jeferson Danilo L. Silva +2
We investigate how the renormalization of the band gap in a planar 2D material is affected by the consideration of two nondispersive semi-infinite dielectrics, with dielectric cons…
Dynamical Casimir effect enhanced by decreasing the mirror reflectivity
Andreson L. C. Rego, Alessandra N. Braga, Jeferson Danilo L. Silva +1
In the present paper, we show that a partially reflecting static mirror with time-dependent properties can produce, via dynamical Casimir effect in the context of a massless scalar…
Motion induced by asymmetric excitation of the quantum vacuum
Jeferson Danilo L. Silva, Alessandra N. Braga, Andreson L. C. Rego +1
During the last fifty-one years, the effect of excitation of the quantum vacuum field induced by its coupling with a moving object has been systematically studied. Here, we propose…
Scattering coefficients and bound states for high-energy transparent interactions
Danilo C. Pedrelli, Jeferson Danilo L. Silva, Alessandra N. Braga +1
We propose a model for energy-dependent interactions which yields scattering coefficients exhibiting full transmission for high-energy incident particles, also compu…
Casimir force between mirrors transparent at high frequencies
Alessandra N. Braga, Jeferson Danilo L. Silva, Danilo T. Alves
We investigate, in the context of a real massless scalar field in dimensions, models of partially reflecting mirrors simulated by Dirac point interactions. In…
Dynamical Casimir effect with mirrors
Jeferson Danilo L. Silva, Alessandra N. Braga, Danilo T. Alves
We calculate the spectrum and the total rate of created particles for a real massless scalar field in dimensions, in the presence of a partially transparent moving mirror sim…
