Casimir effect in Plebański nonlinear electrodynamics with spontaneously Lorentz-breaking magnetic vacua
C. A. Escobar, Román Linares, A. Martín-Ruiz
We study the Casimir effect in a class of gauge-invariant nonlinear electrodynamics models designed to admit spontaneously Lorentz-breaking magnetic vacua. The theory is formulated…

Optical scalar beam propagation in nontrivial spacetime backgrounds
C. A. Escobar, A. Martín-Ruiz, M. Mondragón +1
We study the propagation of structured optical scalar beams in a spacetime background parameterized by a second-rank symmetric tensor. An analytic expression for the Green's functi…
