Effective-metric formulation of Casimir energies in nonlinear scalar and electromagnetic theories
C. A. Escobar
We study the Casimir effect in nonlinear field theories through the effective geometries that \mbox{govern} their linearized fluctuations. Previous analyses of Lorentz-violating sc…
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…
Constitutive Origin of Hamiltonian Degeneracy in Nonlinear Electrodynamics with Spontaneous Lorentz Symmetry Breaking
C. A. Escobar, Román Linares
In Plebański nonlinear electrodynamics with spontaneous Lorentz symmetry breaking, nontrivial magnetic backgrounds are selected by stationary points of an effective Hamiltonian. Pr…
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…
Spontaneous symmetry breaking in models with second-class constraints
C. A. Escobar, Román Linares
In this work the spontaneous symmetry breaking in certain nonlinear theories with second-class constraints is explored. Using the Dirac's method we perform an analysis of the const…
Testing the scalar sector of the Standard-Model Extension with neutron gravity experiments
C. A. Escobar, A. Martín-Ruiz, A. M. Escobar-Ruiz +1
In the present study we analyse, within the scalar sector of the Standard-Model Extension (SME) framework, the influence of a spontaneous Lorentz symmetry breaking on gravitational…
