Lorentz Violation in Goldstone Gravity
Sean M. Carroll, Heywood Tam, Ingunn Kathrine Wehus
We consider a theory of gravity in which a symmetric two-index tensor in Minkowski spacetime acquires a vacuum expectation value (vev) via a potential, thereby breaking Lorentz inv…
Dynamical compactification from de Sitter space
Sean M. Carroll, Matthew C. Johnson, Lisa Randall
We show that D-dimensional de Sitter space is unstable to the nucleation of non-singular geometries containing spacetime regions with different numbers of macroscopic dimensions, l…
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…
Extremal limits and black hole entropy
Sean M. Carroll, Matthew C. Johnson, Lisa Randall
Taking the extremal limit of a non-extremal Reissner-Nordström black hole (by externally varying the mass or charge), the region between the inner and outer event horizons experien…
