Teaching materials aligned or unaligned with the principles of the Cognitive Theory of Multimedia Learning: the choices made by Physics teachers and students
Aline N. Braga, Antonio A. M. Neto, Alessandra N. Braga +3
In a recent study [Rev. Bras. Ens. Fís. vol. 45, 2023], the absence of the Cognitive Theory of Multimedia Learning (CTML) in the curricula of Physics teacher education programs at…

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…

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…
