Perturbative solutions for the bumblebee field in a Schwarzschild background
Demetre Seturidze, Don Colladay
In this paper, we investigate the behavior of a vector field subject to a Lorentz-violating quartic potential on a fixed Schwarzschild background. We analyze the equilibrium config…
CPT-Violating Gravitational Orbital Perturbations
Don Colladay
A model for spontaneous symmetry breaking using a specific form of the bumblebee model is analyzed in the context of a Schwarzschild background metric. The resulting back reaction…
CPT and Lorentz violation en the Photon and -boson sector
D. Colladay, J. P. Noordmans, R. Potting
CPT and Lorentz violation in the photon sector is described within the minimal Standard-Model Extension by a dimension-3 Chern-Simons-like operator parametrized by a four-vector pa…
Quantization of Space-like States in Lorentz-Violating Theories
Don Colladay
Lorentz violation frequently induces modified dispersion relations that can yield space-like states that impede the standard quantization procedures. In certain cases, an extended…
Extended Hamiltonian Formalism and Lorentz-Violating Lagrangians
Don Colladay
A new perspective on the classical mechanical formulation of particle trajectories in lorentz-violating theories is presented. Using the extended hamiltonian formalism, a Legendre…
Comparison Results, Exit Time Moments, And Eigenvalues On Riemannian Manifolds With A Lower Ricci Curvature Bound
Don Colladay, Jeffrey J. Langford, Patrick McDonald
We study the relationship between the geometry of smoothly bounded domains in complete Riemannian manifolds and the associated sequence of -norms of exit time moments for Brow…
