Sigma-Model Aether
Sean M. Carroll, Timothy R. Dulaney, Moira I. Gresham +1
Theories of low-energy Lorentz violation by a fixed-norm "aether" vector field with two-derivative kinetic terms have a globally bounded Hamiltonian and are perturbatively stable o…

Instabilities in the Aether
Sean M. Carroll, Timothy R. Dulaney, Moira I. Gresham +1
We investigate the stability of theories in which Lorentz invariance is spontaneously broken by fixed-norm vector "aether" fields. Models with generic kinetic terms are plagued eit…
