This work tabulates measured and derived values of coefficients for Lorentz and CPT
violation in the standard-model extension. Summary tables are extracted listing maximal …

The realization that Planck-scale physics can be tested with existing technology through the
search for spacetime-symmetry violation brought about the development of a …

Lorentz violation modifies the dispersion relation of gravitational waves (GWs), and induces
birefringence and anisotropy in propagation. Our study shows that Lorentz violation can also …

The classification of Lorentz-and CPT-violating operators in non-Abelian gauge field
theories is performed. We construct all gauge-invariant terms describing propagation and …

Lorentz symmetry is a foundational property of modern physics, underlying the standard
model of particles and general relativity. It is anticipated that these two theories are low …

The effects of Lorentz-violating operators of nonrenormalizable dimension in optical
resonate cavities are studied. Optical-frequency experiments are shown to provide …

We demonstrate technological improvements in phonon sector tests of the Lorentz
invariance that implement quartz bulk acoustic wave oscillators. In this experiment, room …

High-energy physics is primarily concerned with uncovering the laws and principles that
govern nature at the fundamental level. Research in this field usually relies on probing the …

The propagation of electromagnetic waves in a Lorentz-symmetry violating scenario is
investigated in connection with non-linear (photon self-interacting) terms induced by …

We address the study of gauge invariance in the Standard Model extension which
encompasses all Lorentz-violating terms originated by spontaneous symmetry breaking at …
