Fractional cosmic strings
Sebastien Fumeron, Malte Henkel, Alexander Lopez
Topological defects in the framework of effective quantum gravity model are investigated, based on the hypothesis of an effective fractal dimension of the universe. This is done by…
On the possibility of classical vacuum polarization and magnetization
Sébastien Fumeron, Fernando Moraes, Bertrand Berche
It is common practice to take for granted the equality (up to the constant ) of the electric displacement () and electric () field vectors in vacuum.…
Classical Kalb-Ramond field theory in curved spacetimes
Bertrand Berche, Sébastien Fumeron, Fernando Moraes
We propose to develop the Kalb-Ramond theory in four-dimensional spacetime at the level of a classical field theory by following the same formal development steps as in Maxwell the…
Improving student understanding of electrodynamics: the case for differential forms
Sébastien Fumeron, Bertrand Berche, Fernando Moraes
The illuminating role of differential forms in electromagnetism is seldom discussed in the classroom. It is the aim of this article to bring forth some of the relevant insights tha…
The wiggly cosmic string as a waveguide for massless and massive fields
Frankbelson dos S. Azevedo, Fernando Moraes, Francisco Mireles +2
We examine the effect of a wiggly cosmic string for both massless and massive particle propagation along the string axis. We show that the wave equation that governs the propagatio…
Cosmology in the laboratory: an analogy between hyperbolic metamaterials and the Milne universe
David Figueiredo, Fernando Moraes, Sébastien Fumeron +1
This article shows that the compactified Milne universe geometry, a toy model for the big crunch/big bang transition, can be realized in hyperbolic metamaterials, a new class of na…
