Degenerate behavior in nonlinear vacuum electrodynamics
C. A. Escobar, R. Potting
We study nonlinear vacuum electrodynamics in the first-order formulation proposed by Plebański. We analyze in detail the equations of motion, and identify conditions for which a si…
Gravitational Searches for Lorentz Violation with Ultracold Neutrons
C. A. Escobar, A. Martín-Ruiz
We investigate the consequences of Lorentz violation (as expressed within the gravity sector of the Standard-Model Extension) for gravitational quantum states of ultracold neutrons…
Cosmic-ray fermion decay through tau-antitau emission with Lorentz violation
C. A. Escobar, J. P. Noordmans, R. Potting
We study CPT and Lorentz violation in the tau-lepton sector of the Standard Model in the context of the Standard-Model Extension, described by a coefficient which is thus far unbou…
Conditions for the emergence of gauge bosons from spontaneous Lorentz symmetry breaking
C. A. Escobar, L. F. Urrutia
The emergence of gauge particles (e.g., photons and gravitons) as Goldstone bosons arising from spontaneous symmetry breaking is an interesting hypothesis which would provide a dyn…
