Propagation of Laguerre-Gaussian and Bessel-Gaussian scalar beams in an effective anisotropic background
C. A. Escobar, Román Linares, E. Plácido-Flores
We investigate the propagation of structured scalar optical beams in an effective anisotropic background inspired by the scalar sector of the Standard-Model Extension and controlle…

Stable Magnetic Lorentz-Violating Vacua in Gauge-Invariant Nonlinear Electrodynamics
E. Plácido-Flores, Román Linares, V. López +1
We investigate gauge-invariant nonlinear electrodynamics in the Plebański first-order Hamiltonian formulation, taking the single-invariant potential as the primary obje…

Casimir effect between semitransparent mirrors in a Lorentz-violating background
Román Linares, C. A. Escobar, A. Martín-Ruiz +1
We investigate the Casimir effect for a massless scalar field confined between two parallel semitransparent mirrors in a vacuum modified by spontaneous Lorentz symmetry breaking. U…
