Dark Matter, Baryon Asymmetry, and Spontaneous B and L Breaking
Timothy R. Dulaney, Pavel Fileviez Perez, Mark B. Wise
We investigate the dark matter and the cosmological baryon asymmetry in a simple theory where baryon (B) and lepton (L) number are local gauge symmetries that are spontaneously bro…
Primordial Power Spectra from Anisotropic Inflation
Timothy R. Dulaney, Moira I. Gresham
We examine cosmological perturbations in a dynamical theory of inflation in which an Abelian gauge field couples directly to the inflaton, breaking conformal invariance. When the c…
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…
Direction-dependent Jeans instability in an anisotropic Bianchi type I space-time
Timothy R. Dulaney, Moira I. Gresham
We derive the metric for a Bianchi type I space-time with energy density that is dominated by that of a perfect fluid with equation of state and whose anisotropy is seeded b…
Classical stability of a homogeneous, anisotropic inflating space-time
Timothy R. Dulaney, Moira I. Gresham, Mark B. Wise
We study the classical stability of an anisotropic space-time seeded by a spacelike, fixed norm, dynamical vector field in a vacuum-energy-dominated inflationary era. It serves as…
