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 …

We propose a novel experiment to search for axion dark matter that differentiates the phase
velocities of the left-and right-handed polarized photons. Our optical cavity measures the …

We explore the interplay of matter with quantum gravity with a preferred frame to highlight
that the matter sector cannot be protected from the symmetry-breaking effects in the …

We recently set a new limit on the electric dipole moment of the electron (eEDM)(J Baron et
al and ACME collaboration 2014 Science 343 269–272), which represented an order-of …

We have proposed a new approach to search for axion dark matter with an optical ring cavity
[Phys. Rev. Lett. 121, 161301 (2018)]. The coupling of photons to axions or axion-like …

A bstract We address the question whether a violation of Lorentz symmetry can explain the
tension between the measurement and the Standard-Model prediction of the anomalous …

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 …

We examine one of the standard loci for studying electromagnetic wave emission—the
radiation from an oscillating electric dipole—in a model in which the electromagnetic sector …

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

The phase diagram of massless quantum electrodynamics in three space-time dimensions
as a function of fermion flavor number N exhibits two well-known phases: at large N> N c …
