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…
