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…

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…
