Quantum gravity and spacetime symmetries
Ralf Lehnert
Small violations of spacetime symmetries have recently been identified as promising Planck-scale signals. This talk reviews how such violations can arise in various approaches to q…

CPT- and Lorentz-symmetry breaking: a review
Ralf Lehnert
The breakdown of spacetime symmetries has recently been identified as a promising candidate signal for underlying physics, possibly arising through quantum-gravitational effects. T…

Spacetime symmetries of the Lorentz-violating Maxwell-Chern-Simons model
A. J. Hariton, Ralf Lehnert
The spacetime symmetries of classical electrodynamics supplemented with a Chern-Simons term that contains a constant nondynamical 4-vector are investigated. In addition to translat…
