Spontaneous Lorentz violation and asymptotic flatness
Yuri Bonder, Christian Peterson
The Standard Model Extension (SME) is a generic parametrization for Lorentz violation and the phenomenological consequences of the minimal gravity sector of the SME are usually stu…

Explicit Lorentz violation in a static and spherically-symmetric spacetime
Yuri Bonder, Christian Peterson
Lorentz violation is motivated by quantum gravity and it is generically described by nondynamical tensors. In this work a Lorentz violating extension of general relativity is studi…

Symmetries and conserved quantities with arbitrary torsion: A generalization of Killing's theorem
Christian Peterson, Yuri Bonder
When spacetime torsion is present, geodesics and autoparallels generically do not coincide. In this work, the well-known method that uses Killing vectors to solve the geodesic equa…
