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…
Lorentz violating scalar Casimir effect for a -dimensional sphere
A. Martín-Ruiz, C. A. Escobar, A. M. Escobar-Ruiz +1
We investigate the Casimir effect, due to the confinement of a scalar field in a -dimensional sphere, with Lorentz symmetry breaking. The Lorentz-violating part of the theory is…
A non-perturbative approach to the scalar Casimir effect with Lorentz symmetry violation
C. A. Escobar, A. Martín-Ruiz, O. J. Franca +1
We determine the effect of Lorentz invariance violation in the vacuum energy and stress between two parallel plates separated by a distance , in the presence of a massive real s…
Casimir effect in Lorentz-violating scalar field theory: a local approach
C. A. Escobar, Leonardo Medel, A. Martín-Ruiz
We study the Casimir effect in the classical geometry of two parallel conductive plates, separated by a distance , for a Lorentz-breaking extension of the scalar field theory. T…
Nonlinear vacuum electrodynamics and spontaneous breaking of Lorentz symmetry
C. A. Escobar, R. Potting
We study nonlinear vacuum electrodynamics in a first-order formulation proposed by Plebański. By applying a Dirac constraint analysis, we derive an effective Hamiltonian, together…
Testing Lorentz- and CPT-invariance with ultracold neutrons
A. Martín-Ruiz, C. A. Escobar
In this paper we investigate, within the standard model extension framework, the influence of Lorentz- and CPT-violating terms on gravitational quantum states of ultracold neutrons…
